+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+\&\s-1GNU \s0\fBas\fR is really a family of assemblers.
+If you use (or have used) the \s-1GNU\s0 assembler on one architecture, you
+should find a fairly similar environment when you use it on another
+architecture. Each version has much in common with the others,
+including object file formats, most assembler directives (often called
+\&\fIpseudo-ops\fR) and assembler syntax.
+.PP
+\&\fBas\fR is primarily intended to assemble the output of the
+\&\s-1GNU C\s0 compiler \f(CW\*(C`gcc\*(C'\fR for use by the linker
+\&\f(CW\*(C`ld\*(C'\fR. Nevertheless, we've tried to make \fBas\fR
+assemble correctly everything that other assemblers for the same
+machine would assemble.
+Any exceptions are documented explicitly.
+This doesn't mean \fBas\fR always uses the same syntax as another
+assembler for the same architecture; for example, we know of several
+incompatible versions of 680x0 assembly language syntax.
+.PP
+Each time you run \fBas\fR it assembles exactly one source
+program. The source program is made up of one or more files.
+(The standard input is also a file.)
+.PP
+You give \fBas\fR a command line that has zero or more input file
+names. The input files are read (from left file name to right). A
+command line argument (in any position) that has no special meaning
+is taken to be an input file name.
+.PP
+If you give \fBas\fR no file names it attempts to read one input file
+from the \fBas\fR standard input, which is normally your terminal. You
+may have to type \fBctl-D\fR to tell \fBas\fR there is no more program
+to assemble.
+.PP
+Use \fB\-\-\fR if you need to explicitly name the standard input file
+in your command line.
+.PP
+If the source is empty, \fBas\fR produces a small, empty object
+file.
+.PP
+\&\fBas\fR may write warnings and error messages to the standard error
+file (usually your terminal). This should not happen when a compiler
+runs \fBas\fR automatically. Warnings report an assumption made so
+that \fBas\fR could keep assembling a flawed program; errors report a
+grave problem that stops the assembly.
+.PP
+If you are invoking \fBas\fR via the \s-1GNU C\s0 compiler,
+you can use the \fB\-Wa\fR option to pass arguments through to the assembler.
+The assembler arguments must be separated from each other (and the \fB\-Wa\fR)
+by commas. For example:
+.PP
+.Vb 1
+\& gcc \-c \-g \-O \-Wa,\-alh,\-L file.c
+.Ve
+.PP
+This passes two options to the assembler: \fB\-alh\fR (emit a listing to
+standard output with high-level and assembly source) and \fB\-L\fR (retain
+local symbols in the symbol table).
+.PP
+Usually you do not need to use this \fB\-Wa\fR mechanism, since many compiler
+command-line options are automatically passed to the assembler by the compiler.
+(You can call the \s-1GNU\s0 compiler driver with the \fB\-v\fR option to see
+precisely what options it passes to each compilation pass, including the
+assembler.)
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+.IP "\fB@\fR\fIfile\fR" 4
+.IX Item "@file"
+Read command-line options from \fIfile\fR. The options read are
+inserted in place of the original @\fIfile\fR option. If \fIfile\fR
+does not exist, or cannot be read, then the option will be treated
+literally, and not removed.
+.Sp
+Options in \fIfile\fR are separated by whitespace. A whitespace
+character may be included in an option by surrounding the entire
+option in either single or double quotes. Any character (including a
+backslash) may be included by prefixing the character to be included
+with a backslash. The \fIfile\fR may itself contain additional
+@\fIfile\fR options; any such options will be processed recursively.
+.IP "\fB\-a[cdghlmns]\fR" 4

+.IX Item "-as"
+include symbols
+.IP "\fB=file\fR" 4
+.IX Item "=file"
+set the name of the listing file
+.RE
+.RS 4
+.Sp
+You may combine these options; for example, use \fB\-aln\fR for assembly
+listing without forms processing. The \fB=file\fR option, if used, must be
+the last one. By itself, \fB\-a\fR defaults to \fB\-ahls\fR.
+.RE
+.IP "\fB\-\-alternate\fR" 4
+.IX Item "--alternate"
+Begin in alternate macro mode.
+.IP "\fB\-\-compress\-debug\-sections\fR" 4
+.IX Item "--compress-debug-sections"
+Compress \s-1DWARF\s0 debug sections using zlib. The debug sections are renamed
+to begin with \fB.zdebug\fR, and the resulting object file may not be
+compatible with older linkers and object file utilities.
+.IP "\fB\-\-nocompress\-debug\-sections\fR" 4
+.IX Item "--nocompress-debug-sections"
+Do not compress \s-1DWARF\s0 debug sections. This is the default.
+.IP "\fB\-D\fR" 4
+.IX Item "-D"
+Ignored. This option is accepted for script compatibility with calls to
+other assemblers.
+.IP "\fB\-\-debug\-prefix\-map\fR \fIold\fR\fB=\fR\fInew\fR" 4
+.IX Item "--debug-prefix-map old=new"
+When assembling files in directory \fI\fIold\fI\fR, record debugging
+information describing them as in \fI\fInew\fI\fR instead.
+.IP "\fB\-\-defsym\fR \fIsym\fR\fB=\fR\fIvalue\fR" 4
+.IX Item "--defsym sym=value"
+Define the symbol \fIsym\fR to be \fIvalue\fR before assembling the input file.
+\&\fIvalue\fR must be an integer constant. As in C, a leading \fB0x\fR
+indicates a hexadecimal value, and a leading \fB0\fR indicates an octal
+value. The value of the symbol can be overridden inside a source file via the
+use of a \f(CW\*(C`.set\*(C'\fR pseudo-op.
+.IP "\fB\-f\fR" 4
+.IX Item "-f"
+\&\*(L"fast\*(R"\-\-\-skip whitespace and comment preprocessing (assume source is

+.PD
+Generate debugging information for each assembler source line using whichever
+debug format is preferred by the target. This currently means either \s-1STABS,
+ECOFF\s0 or \s-1DWARF2.\s0
+.IP "\fB\-\-gstabs\fR" 4
+.IX Item "--gstabs"
+Generate stabs debugging information for each assembler line. This
+may help debugging assembler code, if the debugger can handle it.
+.IP "\fB\-\-gstabs+\fR" 4
+.IX Item "--gstabs+"
+Generate stabs debugging information for each assembler line, with \s-1GNU\s0
+extensions that probably only gdb can handle, and that could make other
+debuggers crash or refuse to read your program. This
+may help debugging assembler code. Currently the only \s-1GNU\s0 extension is
+the location of the current working directory at assembling time.
+.IP "\fB\-\-gdwarf\-2\fR" 4
+.IX Item "--gdwarf-2"
+Generate \s-1DWARF2\s0 debugging information for each assembler line. This
+may help debugging assembler code, if the debugger can handle it. Note\-\-\-this
+option is only supported by some targets, not all of them.
+.IP "\fB\-\-gdwarf\-sections\fR" 4
+.IX Item "--gdwarf-sections"
+Instead of creating a .debug_line section, create a series of
+\&.debug_line.\fIfoo\fR sections where \fIfoo\fR is the name of the
+corresponding code section. For example a code section called \fI.text.func\fR
+will have its dwarf line number information placed into a section called
+\&\fI.debug_line.text.func\fR. If the code section is just called \fI.text\fR
+then debug line section will still be called just \fI.debug_line\fR without any
+suffix.

+.IX Item "--size-check=error"
+.PD 0

+Don't warn about signed overflow.
+.IP "\fB\-K\fR" 4
+.IX Item "-K"
+Issue warnings when difference tables altered for long displacements.
+.IP "\fB\-L\fR" 4
+.IX Item "-L"
+.PD 0
+.IP "\fB\-\-keep\-locals\fR" 4
+.IX Item "--keep-locals"
+.PD
+Keep (in the symbol table) local symbols. These symbols start with
+system-specific local label prefixes, typically \fB.L\fR for \s-1ELF\s0 systems
+or \fBL\fR for traditional a.out systems.
+.IP "\fB\-\-listing\-lhs\-width=\fR\fInumber\fR" 4
+.IX Item "--listing-lhs-width=number"
+Set the maximum width, in words, of the output data column for an assembler
+listing to \fInumber\fR.
+.IP "\fB\-\-listing\-lhs\-width2=\fR\fInumber\fR" 4
+.IX Item "--listing-lhs-width2=number"
+Set the maximum width, in words, of the output data column for continuation
+lines in an assembler listing to \fInumber\fR.
+.IP "\fB\-\-listing\-rhs\-width=\fR\fInumber\fR" 4
+.IX Item "--listing-rhs-width=number"
+Set the maximum width of an input source line, as displayed in a listing, to
+\&\fInumber\fR bytes.
+.IP "\fB\-\-listing\-cont\-lines=\fR\fInumber\fR" 4
+.IX Item "--listing-cont-lines=number"
+Set the maximum number of lines printed in a listing for a single line of input
+to \fInumber\fR + 1.
+.IP "\fB\-o\fR \fIobjfile\fR" 4
+.IX Item "-o objfile"
+Name the object-file output from \fBas\fR \fIobjfile\fR.
+.IP "\fB\-R\fR" 4
+.IX Item "-R"
+Fold the data section into the text section.
+.Sp
+Set the default size of \s-1GAS\s0's hash tables to a prime number close to
+\&\fInumber\fR. Increasing this value can reduce the length of time it takes the
+assembler to perform its tasks, at the expense of increasing the assembler's
+memory requirements. Similarly reducing this value can reduce the memory
+requirements at the expense of speed.
+.IP "\fB\-\-reduce\-memory\-overheads\fR" 4
+.IX Item "--reduce-memory-overheads"
+This option reduces \s-1GAS\s0's memory requirements, at the expense of making the
+assembly processes slower. Currently this switch is a synonym for
+\&\fB\-\-hash\-size=4051\fR, but in the future it may have other effects as well.
+.IP "\fB\-\-statistics\fR" 4
+.IX Item "--statistics"
+Print the maximum space (in bytes) and total time (in seconds) used by
+assembly.

+.IP "\fB\-\-text\-section\-literals | \-\-no\-text\-section\-literals\fR" 4
+.IX Item "--text-section-literals | --no-text-section-literals"
+Control the treatment of literal pools. The default is
+\&\fB\-\-no\-text\-section\-literals\fR, which places literals in
+separate sections in the output file. This allows the literal pool to be
+placed in a data \s-1RAM/ROM. \s0 With \fB\-\-text\-section\-literals\fR, the
+literals are interspersed in the text section in order to keep them as
+close as possible to their references. This may be necessary for large
+assembly files, where the literals would otherwise be out of range of the
+\&\f(CW\*(C`L32R\*(C'\fR instructions in the text section. These options only affect
+literals referenced via PC-relative \f(CW\*(C`L32R\*(C'\fR instructions; literals
+for absolute mode \f(CW\*(C`L32R\*(C'\fR instructions are handled separately.
+.IP "\fB\-\-absolute\-literals | \-\-no\-absolute\-literals\fR" 4
+.IX Item "--absolute-literals | --no-absolute-literals"
+Indicate to the assembler whether \f(CW\*(C`L32R\*(C'\fR instructions use absolute
+or PC-relative addressing. If the processor includes the absolute
+addressing option, the default is to use absolute \f(CW\*(C`L32R\*(C'\fR
+relocations. Otherwise, only the PC-relative \f(CW\*(C`L32R\*(C'\fR relocations
+can be used.
+.IP "\fB\-\-target\-align | \-\-no\-target\-align\fR" 4
+.IX Item "--target-align | --no-target-align"
+Enable or disable automatic alignment to reduce branch penalties at some
+expense in code size. This optimization is enabled by default. Note
+that the assembler will always align instructions like \f(CW\*(C`LOOP\*(C'\fR that
+have fixed alignment requirements.
+.IP "\fB\-\-longcalls | \-\-no\-longcalls\fR" 4
+.IX Item "--longcalls | --no-longcalls"
+Enable or disable transformation of call instructions to allow calls
+across a greater range of addresses. This option should be used when call
+targets can potentially be out of range. It may degrade both code size
+and performance, but the linker can generally optimize away the
+unnecessary overhead when a call ends up within range. The default is
+\&\fB\-\-no\-longcalls\fR.
+.IP "\fB\-\-transform | \-\-no\-transform\fR" 4
+.IX Item "--transform | --no-transform"
+Enable or disable all assembler transformations of Xtensa instructions,
+including both relaxation and optimization. The default is
+\&\fB\-\-transform\fR; \fB\-\-no\-transform\fR should only be used in the
+rare cases when the instructions must be exactly as specified in the
+assembly source. Using \fB\-\-no\-transform\fR causes out of range
+instruction operands to be errors.
+.IP "\fB\-\-rename\-section\fR \fIoldname\fR\fB=\fR\fInewname\fR" 4
+.IX Item "--rename-section oldname=newname"
+Rename the \fIoldname\fR section to \fInewname\fR. This option can be used
+multiple times to rename multiple sections.
+.IP "\fB\-\-trampolines | \-\-no\-trampolines\fR" 4
+.IX Item "--trampolines | --no-trampolines"
+Enable or disable transformation of jump instructions to allow jumps
+across a greater range of addresses. This option should be used when jump targets can
+potentially be out of range. In the absence of such jumps this option
+does not affect code size or performance. The default is
+\&\fB\-\-trampolines\fR.

+
+`@FILE'
+ Read command-line options from FILE. The options read are
+ inserted in place of the original @FILE option. If FILE does not
+ exist, or cannot be read, then the option will be treated
+ literally, and not removed.
+
+ Options in FILE are separated by whitespace. A whitespace
+ character may be included in an option by surrounding the entire
+ option in either single or double quotes. Any character
+ (including a backslash) may be included by prefixing the character
+ to be included with a backslash. The FILE may itself contain
+ additional @FILE options; any such options will be processed
+ recursively.
+
+`-a[cdghlmns]'
+ Turn on listings, in any of a variety of ways:
+
+ `-ac'
+ omit false conditionals
+
+ `-ad'
+ omit debugging directives
+
+ `-ag'
+ include general information, like as version and options
+ passed
+
+ `-ah'
+ include high-level source
+
+ `-al'
+ include assembly
+
+ `-am'
+ include macro expansions
+
+ `-an'
+ omit forms processing
+
+ `-as'
+ include symbols
+
+ `=file'
+ set the name of the listing file
+
+ You may combine these options; for example, use `-aln' for assembly
+ listing without forms processing. The `=file' option, if used,
+ must be the last one. By itself, `-a' defaults to `-ahls'.
+
+`--alternate'
+ Begin in alternate macro mode. *Note `.altmacro': Altmacro.
+
+`--compress-debug-sections'
+ Compress DWARF debug sections using zlib. The debug sections are
+ renamed to begin with `.zdebug', and the resulting object file may
+ not be compatible with older linkers and object file utilities.
+
+`--nocompress-debug-sections'
+ Do not compress DWARF debug sections. This is the default.
+
+`-D'
+ Ignored. This option is accepted for script compatibility with
+ calls to other assemblers.
+
+`--debug-prefix-map OLD=NEW'
+ When assembling files in directory `OLD', record debugging
+ information describing them as in `NEW' instead.
+
+`--defsym SYM=VALUE'
+ Define the symbol SYM to be VALUE before assembling the input file.
+ VALUE must be an integer constant. As in C, a leading `0x'
+ indicates a hexadecimal value, and a leading `0' indicates an octal
+ value. The value of the symbol can be overridden inside a source
+ file via the use of a `.set' pseudo-op.
+
+`-f'
+ "fast"--skip whitespace and comment preprocessing (assume source is
+ compiler output).
+
+`-g'
+`--gen-debug'
+ Generate debugging information for each assembler source line
+ using whichever debug format is preferred by the target. This
+ currently means either STABS, ECOFF or DWARF2.
+
+`--gstabs'
+ Generate stabs debugging information for each assembler line. This
+ may help debugging assembler code, if the debugger can handle it.
+
+`--gstabs+'
+ Generate stabs debugging information for each assembler line, with
+ GNU extensions that probably only gdb can handle, and that could
+ make other debuggers crash or refuse to read your program. This
+ may help debugging assembler code. Currently the only GNU
+ extension is the location of the current working directory at
+ assembling time.
+
+`--gdwarf-2'
+ Generate DWARF2 debugging information for each assembler line.
+ This may help debugging assembler code, if the debugger can handle
+ it. Note--this option is only supported by some targets, not all
+ of them.
+
+`--gdwarf-sections'
+ Instead of creating a .debug_line section, create a series of
+ .debug_line.FOO sections where FOO is the name of the
+ corresponding code section. For example a code section called
+ .TEXT.FUNC will have its dwarf line number information placed into
+ a section called .DEBUG_LINE.TEXT.FUNC. If the code section is
+ just called .TEXT then debug line section will still be called
+ just .DEBUG_LINE without any suffix.
+
+`--size-check=error'
+`--size-check=warning'
+ Issue an error or warning for invalid ELF .size directive.
+
+`--help'
+ Print a summary of the command line options and exit.
+
+`--target-help'
+ Print a summary of all target specific options and exit.
+
+`-I DIR'
+ Add directory DIR to the search list for `.include' directives.
+
+`-J'
+ Don't warn about signed overflow.
+
+`-K'
+ Issue warnings when difference tables altered for long
+ displacements.
+
+`-L'
+`--keep-locals'
+ Keep (in the symbol table) local symbols. These symbols start with
+ system-specific local label prefixes, typically `.L' for ELF
+ systems or `L' for traditional a.out systems. *Note Symbol
+ Names::.
+
+`--listing-lhs-width=NUMBER'
+ Set the maximum width, in words, of the output data column for an
+ assembler listing to NUMBER.
+
+`--listing-lhs-width2=NUMBER'
+ Set the maximum width, in words, of the output data column for
+ continuation lines in an assembler listing to NUMBER.
+
+`--listing-rhs-width=NUMBER'
+ Set the maximum width of an input source line, as displayed in a
+ listing, to NUMBER bytes.
+
+`--listing-cont-lines=NUMBER'
+ Set the maximum number of lines printed in a listing for a single
+ line of input to NUMBER + 1.
+
+`-o OBJFILE'
+ Name the object-file output from `as' OBJFILE.
+
+`-R'
+ Fold the data section into the text section.
+
+ Set the default size of GAS's hash tables to a prime number close
+ to NUMBER. Increasing this value can reduce the length of time it
+ takes the assembler to perform its tasks, at the expense of
+ increasing the assembler's memory requirements. Similarly
+ reducing this value can reduce the memory requirements at the
+ expense of speed.
+
+`--reduce-memory-overheads'
+ This option reduces GAS's memory requirements, at the expense of
+ making the assembly processes slower. Currently this switch is a
+ synonym for `--hash-size=4051', but in the future it may have
+ other effects as well.
+
+`--statistics'
+ Print the maximum space (in bytes) and total time (in seconds)
+ used by assembly.
+
+`--strip-local-absolute'
+ Remove local absolute symbols from the outgoing symbol table.
+
+`-v'
+`-version'
+ Print the `as' version.
+
+`--version'
+ Print the `as' version and exit.
+
+`-W'
+`--no-warn'
+ Suppress warning messages.
+
+`--fatal-warnings'
+ Treat warnings as errors.
+
+`--warn'
+ Don't suppress warning messages or treat them as errors.
+
+`-w'
+ Ignored.
+
+`-x'
+ Ignored.
+
+`-Z'
+ Generate an object file even after errors.
+
+`-- | FILES ...'
+ Standard input, or source files to assemble.

+ then exit. This option is only useful for testing `as'.
+
+
+ The following options are available when `as' is configured for the
+SPARC architecture:
+
+`-Av6 | -Av7 | -Av8 | -Asparclet | -Asparclite'
+`-Av8plus | -Av8plusa | -Av9 | -Av9a'
+ Explicitly select a variant of the SPARC architecture.
+
+ `-Av8plus' and `-Av8plusa' select a 32 bit environment. `-Av9'
+ and `-Av9a' select a 64 bit environment.
+
+ `-Av8plusa' and `-Av9a' enable the SPARC V9 instruction set with
+ UltraSPARC extensions.
+
+`-xarch=v8plus | -xarch=v8plusa'
+ For compatibility with the Solaris v9 assembler. These options are
+ equivalent to -Av8plus and -Av8plusa, respectively.
+
+`-bump'
+ Warn when the assembler switches to another architecture.
+
+ The following options are available when as is configured for the
+'c54x architecture.
+
+`-mfar-mode'
+ Enable extended addressing mode. All addresses and relocations
+ will assume extended addressing (usually 23 bits).
+
+`-mcpu=CPU_VERSION'
+ Sets the CPU version being compiled for.
+
+`-merrors-to-file FILENAME'
+ Redirect error output to a file, for broken systems which don't
+ support such behaviour in the shell.
+
+ The following options are available when as is configured for a MIPS
+processor.
+
+`-G NUM'
+ This option sets the largest size of an object that can be
+ referenced implicitly with the `gp' register. It is only accepted
+ for targets that use ECOFF format, such as a DECstation running
+ Ultrix. The default value is 8.

+`-mno-pdr'
+ Control generation of `.pdr' sections.
+
+`-mgp32'
+`-mfp32'
+ The register sizes are normally inferred from the ISA and ABI, but

+ bits wide at all times. `-mgp32' controls the size of
+ general-purpose registers and `-mfp32' controls the size of
+ floating-point registers.
+
+`-mgp64'
+`-mfp64'
+ The register sizes are normally inferred from the ISA and ABI, but
+ these flags force a certain group of registers to be treated as 64
+ bits wide at all times. `-mgp64' controls the size of
+ general-purpose registers and `-mfp64' controls the size of
+ floating-point registers.
+
+`-mfpxx'
+ The register sizes are normally inferred from the ISA and ABI, but
+ using this flag in combination with `-mabi=32' enables an ABI
+ variant which will operate correctly with floating-point registers
+ which are 32 or 64 bits wide.
+
+`-modd-spreg'
+`-mno-odd-spreg'
+ Enable use of floating-point operations on odd-numbered

+ implies `-mno-odd-spreg', otherwise the default is `-modd-spreg'.
+
+`-mips16'
+`-no-mips16'
+ Generate code for the MIPS 16 processor. This is equivalent to
+ putting `.set mips16' at the start of the assembly file.
+ `-no-mips16' turns off this option.
+
+`-mmicromips'
+`-mno-micromips'
+ Generate code for the microMIPS processor. This is equivalent to
+ putting `.set micromips' at the start of the assembly file.
+ `-mno-micromips' turns off this option. This is equivalent to
+ putting `.set nomicromips' at the start of the assembly file.
+
+`-msmartmips'
+`-mno-smartmips'
+ Enables the SmartMIPS extension to the MIPS32 instruction set.
+ This is equivalent to putting `.set smartmips' at the start of the
+ assembly file. `-mno-smartmips' turns off this option.
+
+`-mips3d'
+`-no-mips3d'
+ Generate code for the MIPS-3D Application Specific Extension.
+ This tells the assembler to accept MIPS-3D instructions.
+ `-no-mips3d' turns off this option.
+
+`-mdmx'
+`-no-mdmx'
+ Generate code for the MDMX Application Specific Extension. This
+ tells the assembler to accept MDMX instructions. `-no-mdmx' turns
+ off this option.
+
+`-mdsp'
+`-mno-dsp'
+ Generate code for the DSP Release 1 Application Specific Extension.
+ This tells the assembler to accept DSP Release 1 instructions.
+ `-mno-dsp' turns off this option.
+
+`-mdspr2'
+`-mno-dspr2'
+ Generate code for the DSP Release 2 Application Specific Extension.
+ This option implies -mdsp. This tells the assembler to accept DSP
+ Release 2 instructions. `-mno-dspr2' turns off this option.
+
+`-mmsa'
+`-mno-msa'
+ Generate code for the MIPS SIMD Architecture Extension. This
+ tells the assembler to accept MSA instructions. `-mno-msa' turns
+ off this option.
+
+`-mxpa'
+`-mno-xpa'
+ Generate code for the MIPS eXtended Physical Address (XPA)
+ Extension. This tells the assembler to accept XPA instructions.
+ `-mno-xpa' turns off this option.
+
+`-mmt'
+`-mno-mt'
+ Generate code for the MT Application Specific Extension. This
+ tells the assembler to accept MT instructions. `-mno-mt' turns
+ off this option.
+
+`-mmcu'
+`-mno-mcu'
+ Generate code for the MCU Application Specific Extension. This
+ tells the assembler to accept MCU instructions. `-mno-mcu' turns
+ off this option.
+
+`-minsn32'
+`-mno-insn32'
+ Only use 32-bit instruction encodings when generating code for the
+ microMIPS processor. This option inhibits the use of any 16-bit
+ instructions. This is equivalent to putting `.set insn32' at the
+ start of the assembly file. `-mno-insn32' turns off this option.
+ This is equivalent to putting `.set noinsn32' at the start of the
+ assembly file. By default `-mno-insn32' is selected, allowing all
+ instructions to be used.
+
+`--construct-floats'
+`--no-construct-floats'
+ The `--no-construct-floats' option disables the construction of
+ double width floating point constants by loading the two halves of
+ the value into the two single width floating point registers that
+ make up the double width register. By default
+ `--construct-floats' is selected, allowing construction of these
+ floating point constants.
+
+`--relax-branch'
+`--no-relax-branch'
+ The `--relax-branch' option enables the relaxation of out-of-range
+ branches. By default `--no-relax-branch' is selected, causing any
+ out-of-range branches to produce an error.
+
+`-mnan=ENCODING'
+ Select between the IEEE 754-2008 (`-mnan=2008') or the legacy
+ (`-mnan=legacy') NaN encoding format. The latter is the default.
+
+`--emulation=NAME'
+ This option was formerly used to switch between ELF and ECOFF
+ output on targets like IRIX 5 that supported both. MIPS ECOFF
+ support was removed in GAS 2.24, so the option now serves little
+ purpose. It is retained for backwards compatibility.
+
+ The available configuration names are: `mipself', `mipslelf' and
+ `mipsbelf'. Choosing `mipself' now has no effect, since the output
+ is always ELF. `mipslelf' and `mipsbelf' select little- and
+ big-endian output respectively, but `-EL' and `-EB' are now the
+ preferred options instead.
+
+`-nocpp'
+ `as' ignores this option. It is accepted for compatibility with
+ the native tools.
+
+`--trap'
+`--no-trap'
+`--break'
+`--no-break'
+ Control how to deal with multiplication overflow and division by
+ zero. `--trap' or `--no-break' (which are synonyms) take a trap
+ exception (and only work for Instruction Set Architecture level 2
+ and higher); `--break' or `--no-trap' (also synonyms, and the
+ default) take a break exception.
+
+`-n'
+ When this option is used, `as' will issue a warning every time it
+ generates a nop instruction from a macro.
+
+ The following options are available when as is configured for an
+MCore processor.
+
+`-jsri2bsr'
+`-nojsri2bsr'
+ Enable or disable the JSRI to BSR transformation. By default this
+ is enabled. The command line option `-nojsri2bsr' can be used to
+ disable it.
+
+`-sifilter'
+`-nosifilter'
+ Enable or disable the silicon filter behaviour. By default this
+ is disabled. The default can be overridden by the `-sifilter'
+ command line option.
+
+`-relax'
+ Alter jump instructions for long displacements.
+
+`-mcpu=[210|340]'
+ Select the cpu type on the target hardware. This controls which
+ instructions can be assembled.
+
+`-EB'
+ Assemble for a big endian target.
+
+`-EL'
+ Assemble for a little endian target.

+
+1.1 Structure of this Manual
+============================
+
+This manual is intended to describe what you need to know to use GNU
+`as'. We cover the syntax expected in source files, including notation
+for symbols, constants, and expressions; the directives that `as'
+understands; and of course how to invoke `as'.
+
+ This manual also describes some of the machine-dependent features of
+various flavors of the assembler.
+
+ On the other hand, this manual is _not_ intended as an introduction
+to programming in assembly language--let alone programming in general!
+In a similar vein, we make no attempt to introduce the machine
+architecture; we do _not_ describe the instruction set, standard
+mnemonics, registers or addressing modes that are standard to a
+particular architecture. You may want to consult the manufacturer's
+machine architecture manual for this information.
+
+
+File: as.info, Node: GNU Assembler, Next: Object Formats, Prev: Manual, Up: Overview
+
+1.2 The GNU Assembler
+=====================
+
+GNU `as' is really a family of assemblers. If you use (or have used)
+the GNU assembler on one architecture, you should find a fairly similar
+environment when you use it on another architecture. Each version has
+much in common with the others, including object file formats, most
+assembler directives (often called "pseudo-ops") and assembler syntax.
+
+ `as' is primarily intended to assemble the output of the GNU C
+compiler `gcc' for use by the linker `ld'. Nevertheless, we've tried
+to make `as' assemble correctly everything that other assemblers for
+the same machine would assemble. Any exceptions are documented
+explicitly (*note Machine Dependencies::). This doesn't mean `as'
+always uses the same syntax as another assembler for the same
+architecture; for example, we know of several incompatible versions of
+680x0 assembly language syntax.
+
+ Unlike older assemblers, `as' is designed to assemble a source
+program in one pass of the source file. This has a subtle impact on the
+`.org' directive (*note `.org': Org.).
+
+
+File: as.info, Node: Object Formats, Next: Command Line, Prev: GNU Assembler, Up: Overview
+
+1.3 Object File Formats
+=======================
+
+The GNU assembler can be configured to produce several alternative
+object file formats. For the most part, this does not affect how you
+write assembly language programs; but directives for debugging symbols
+are typically different in different file formats. *Note Symbol
+Attributes: Symbol Attributes.
+
+
+File: as.info, Node: Command Line, Next: Input Files, Prev: Object Formats, Up: Overview
+
+1.4 Command Line
+================
+
+After the program name `as', the command line may contain options and
+file names. Options may appear in any order, and may be before, after,
+or between file names. The order of file names is significant.
+
+ `--' (two hyphens) by itself names the standard input file
+explicitly, as one of the files for `as' to assemble.
+
+ Except for `--' any command line argument that begins with a hyphen
+(`-') is an option. Each option changes the behavior of `as'. No
+option changes the way another option works. An option is a `-'
+followed by one or more letters; the case of the letter is important.
+All options are optional.
+
+ Some options expect exactly one file name to follow them. The file
+name may either immediately follow the option's letter (compatible with
+older assemblers) or it may be the next command argument (GNU
+standard). These two command lines are equivalent:
+
+ as -o my-object-file.o mumble.s
+ as -omy-object-file.o mumble.s
+
+
+File: as.info, Node: Input Files, Next: Object, Prev: Command Line, Up: Overview
+
+1.5 Input Files
+===============
+
+We use the phrase "source program", abbreviated "source", to describe
+the program input to one run of `as'. The program may be in one or
+more files; how the source is partitioned into files doesn't change the
+meaning of the source.
+
+ The source program is a concatenation of the text in all the files,
+in the order specified.
+
+ Each time you run `as' it assembles exactly one source program. The
+source program is made up of one or more files. (The standard input is
+also a file.)
+
+ You give `as' a command line that has zero or more input file names.
+The input files are read (from left file name to right). A command
+line argument (in any position) that has no special meaning is taken to
+be an input file name.
+
+ If you give `as' no file names it attempts to read one input file
+from the `as' standard input, which is normally your terminal. You may
+have to type <ctl-D> to tell `as' there is no more program to assemble.
+
+ Use `--' if you need to explicitly name the standard input file in
+your command line.
+
+ If the source is empty, `as' produces a small, empty object file.
+
+Filenames and Line-numbers
+--------------------------
+
+There are two ways of locating a line in the input file (or files) and
+either may be used in reporting error messages. One way refers to a
+line number in a physical file; the other refers to a line number in a
+"logical" file. *Note Error and Warning Messages: Errors.
+
+ "Physical files" are those files named in the command line given to
+`as'.
+
+ "Logical files" are simply names declared explicitly by assembler
+directives; they bear no relation to physical files. Logical file
+names help error messages reflect the original source file, when `as'
+source is itself synthesized from other files. `as' understands the
+`#' directives emitted by the `gcc' preprocessor. See also *Note
+`.file': File.
+
+
+File: as.info, Node: Object, Next: Errors, Prev: Input Files, Up: Overview
+
+1.6 Output (Object) File
+========================
+
+Every time you run `as' it produces an output file, which is your
+assembly language program translated into numbers. This file is the
+object file. Its default name is `a.out'. You can give it another
+name by using the `-o' option. Conventionally, object file names end
+with `.o'. The default name is used for historical reasons: older
+assemblers were capable of assembling self-contained programs directly
+into a runnable program. (For some formats, this isn't currently
+possible, but it can be done for the `a.out' format.)
+
+ The object file is meant for input to the linker `ld'. It contains
+assembled program code, information to help `ld' integrate the
+assembled program into a runnable file, and (optionally) symbolic
+information for the debugger.
+
+
+File: as.info, Node: Errors, Prev: Object, Up: Overview
+
+1.7 Error and Warning Messages
+==============================
+
+`as' may write warnings and error messages to the standard error file
+(usually your terminal). This should not happen when a compiler runs
+`as' automatically. Warnings report an assumption made so that `as'
+could keep assembling a flawed program; errors report a grave problem
+that stops the assembly.
+
+ Warning messages have the format
+
+ file_name:NNN:Warning Message Text
+
+(where NNN is a line number). If a logical file name has been given
+(*note `.file': File.) it is used for the filename, otherwise the name
+of the current input file is used. If a logical line number was given
+(*note `.line': Line.) then it is used to calculate the number printed,
+otherwise the actual line in the current source file is printed. The
+message text is intended to be self explanatory (in the grand Unix
+tradition).
+
+ Error messages have the format
+ file_name:NNN:FATAL:Error Message Text
+ The file name and line number are derived as for warning messages.
+The actual message text may be rather less explanatory because many of
+them aren't supposed to happen.

+
+2 Command-Line Options
+**********************
+
+This chapter describes command-line options available in _all_ versions
+of the GNU assembler; see *Note Machine Dependencies::, for options
+specific to particular machine architectures.
+
+ If you are invoking `as' via the GNU C compiler, you can use the
+`-Wa' option to pass arguments through to the assembler. The assembler
+arguments must be separated from each other (and the `-Wa') by commas.
+For example:
+
+ gcc -c -g -O -Wa,-alh,-L file.c
+
+This passes two options to the assembler: `-alh' (emit a listing to
+standard output with high-level and assembly source) and `-L' (retain
+local symbols in the symbol table).
+
+ Usually you do not need to use this `-Wa' mechanism, since many
+compiler command-line options are automatically passed to the assembler
+by the compiler. (You can call the GNU compiler driver with the `-v'
+option to see precisely what options it passes to each compilation
+pass, including the assembler.)
+

+
+
+File: as.info, Node: a, Next: alternate, Up: Invoking
+
+2.1 Enable Listings: `-a[cdghlns]'
+==================================
+
+These options enable listing output from the assembler. By itself,
+`-a' requests high-level, assembly, and symbols listing. You can use
+other letters to select specific options for the list: `-ah' requests a
+high-level language listing, `-al' requests an output-program assembly
+listing, and `-as' requests a symbol table listing. High-level
+listings require that a compiler debugging option like `-g' be used,
+and that assembly listings (`-al') be requested also.
+
+ Use the `-ag' option to print a first section with general assembly
+information, like as version, switches passed, or time stamp.
+
+ Use the `-ac' option to omit false conditionals from a listing. Any
+lines which are not assembled because of a false `.if' (or `.ifdef', or
+any other conditional), or a true `.if' followed by an `.else', will be
+omitted from the listing.
+
+ Use the `-ad' option to omit debugging directives from the listing.
+
+ Once you have specified one of these options, you can further control
+listing output and its appearance using the directives `.list',
+`.nolist', `.psize', `.eject', `.title', and `.sbttl'. The `-an'
+option turns off all forms processing. If you do not request listing
+output with one of the `-a' options, the listing-control directives
+have no effect.
+
+ The letters after `-a' may be combined into one option, _e.g._,
+`-aln'.
+
+ Note if the assembler source is coming from the standard input (e.g.,
+because it is being created by `gcc' and the `-pipe' command line switch
+is being used) then the listing will not contain any comments or
+preprocessor directives. This is because the listing code buffers
+input source lines from stdin only after they have been preprocessed by
+the assembler. This reduces memory usage and makes the code more
+efficient.
+
+
+File: as.info, Node: alternate, Next: D, Prev: a, Up: Invoking
+
+2.2 `--alternate'
+=================
+
+Begin in alternate macro mode, see *Note `.altmacro': Altmacro.
+
+
+File: as.info, Node: D, Next: f, Prev: alternate, Up: Invoking
+
+2.3 `-D'
+========
+
+This option has no effect whatsoever, but it is accepted to make it more
+likely that scripts written for other assemblers also work with `as'.
+
+
+File: as.info, Node: f, Next: I, Prev: D, Up: Invoking
+
+2.4 Work Faster: `-f'
+=====================
+
+`-f' should only be used when assembling programs written by a
+(trusted) compiler. `-f' stops the assembler from doing whitespace and
+comment preprocessing on the input file(s) before assembling them.
+*Note Preprocessing: Preprocessing.
+
+ _Warning:_ if you use `-f' when the files actually need to be
+ preprocessed (if they contain comments, for example), `as' does
+ not work correctly.
+
+
+File: as.info, Node: I, Next: K, Prev: f, Up: Invoking
+
+2.5 `.include' Search Path: `-I' PATH
+=====================================
+
+Use this option to add a PATH to the list of directories `as' searches
+for files specified in `.include' directives (*note `.include':
+Include.). You may use `-I' as many times as necessary to include a
+variety of paths. The current working directory is always searched
+first; after that, `as' searches any `-I' directories in the same order
+as they were specified (left to right) on the command line.
+
+
+File: as.info, Node: K, Next: L, Prev: I, Up: Invoking
+
+2.6 Difference Tables: `-K'
+===========================
+
+`as' sometimes alters the code emitted for directives of the form
+`.word SYM1-SYM2'. *Note `.word': Word. You can use the `-K' option
+if you want a warning issued when this is done.
+
+
+File: as.info, Node: L, Next: listing, Prev: K, Up: Invoking
+
+2.7 Include Local Symbols: `-L'
+===============================
+
+Symbols beginning with system-specific local label prefixes, typically
+`.L' for ELF systems or `L' for traditional a.out systems, are called
+"local symbols". *Note Symbol Names::. Normally you do not see such
+symbols when debugging, because they are intended for the use of
+programs (like compilers) that compose assembler programs, not for your
+notice. Normally both `as' and `ld' discard such symbols, so you do
+not normally debug with them.
+
+ This option tells `as' to retain those local symbols in the object
+file. Usually if you do this you also tell the linker `ld' to preserve
+those symbols.
+
+
+File: as.info, Node: listing, Next: M, Prev: L, Up: Invoking
+
+2.8 Configuring listing output: `--listing'
+===========================================
+
+The listing feature of the assembler can be enabled via the command
+line switch `-a' (*note a::). This feature combines the input source
+file(s) with a hex dump of the corresponding locations in the output
+object file, and displays them as a listing file. The format of this
+listing can be controlled by directives inside the assembler source
+(i.e., `.list' (*note List::), `.title' (*note Title::), `.sbttl'
+(*note Sbttl::), `.psize' (*note Psize::), and `.eject' (*note Eject::)
+and also by the following switches:
+
+`--listing-lhs-width=`number''
+ Sets the maximum width, in words, of the first line of the hex
+ byte dump. This dump appears on the left hand side of the listing
+ output.
+
+`--listing-lhs-width2=`number''
+ Sets the maximum width, in words, of any further lines of the hex
+ byte dump for a given input source line. If this value is not
+ specified, it defaults to being the same as the value specified
+ for `--listing-lhs-width'. If neither switch is used the default
+ is to one.
+
+`--listing-rhs-width=`number''
+ Sets the maximum width, in characters, of the source line that is
+ displayed alongside the hex dump. The default value for this
+ parameter is 100. The source line is displayed on the right hand
+ side of the listing output.
+
+`--listing-cont-lines=`number''
+ Sets the maximum number of continuation lines of hex dump that
+ will be displayed for a given single line of source input. The
+ default value is 4.

+
+2.9 Assemble in MRI Compatibility Mode: `-M'
+============================================
+
+The `-M' or `--mri' option selects MRI compatibility mode. This
+changes the syntax and pseudo-op handling of `as' to make it compatible
+with the `ASM68K' or the `ASM960' (depending upon the configured
+target) assembler from Microtec Research. The exact nature of the MRI
+syntax will not be documented here; see the MRI manuals for more
+information. Note in particular that the handling of macros and macro
+arguments is somewhat different. The purpose of this option is to
+permit assembling existing MRI assembler code using `as'.
+
+ The MRI compatibility is not complete. Certain operations of the
+MRI assembler depend upon its object file format, and can not be
+supported using other object file formats. Supporting these would
+require enhancing each object file format individually. These are:
+
+ * global symbols in common section
+
+ The m68k MRI assembler supports common sections which are merged
+ by the linker. Other object file formats do not support this.
+ `as' handles common sections by treating them as a single common
+ symbol. It permits local symbols to be defined within a common
+ section, but it can not support global symbols, since it has no
+ way to describe them.
+
+ * complex relocations
+
+ The MRI assemblers support relocations against a negated section
+ address, and relocations which combine the start addresses of two
+ or more sections. These are not support by other object file
+ formats.
+
+ * `END' pseudo-op specifying start address
+
+ The MRI `END' pseudo-op permits the specification of a start
+ address. This is not supported by other object file formats. The
+ start address may instead be specified using the `-e' option to
+ the linker, or in a linker script.
+
+ * `IDNT', `.ident' and `NAME' pseudo-ops
+
+ The MRI `IDNT', `.ident' and `NAME' pseudo-ops assign a module
+ name to the output file. This is not supported by other object
+ file formats.
+
+ * `ORG' pseudo-op
+
+ The m68k MRI `ORG' pseudo-op begins an absolute section at a given
+ address. This differs from the usual `as' `.org' pseudo-op, which
+ changes the location within the current section. Absolute
+ sections are not supported by other object file formats. The
+ address of a section may be assigned within a linker script.
+
+ There are some other features of the MRI assembler which are not
+supported by `as', typically either because they are difficult or
+because they seem of little consequence. Some of these may be
+supported in future releases.
+
+ * EBCDIC strings
+
+ EBCDIC strings are not supported.
+
+ * packed binary coded decimal
+
+ Packed binary coded decimal is not supported. This means that the
+ `DC.P' and `DCB.P' pseudo-ops are not supported.
+
+ * `FEQU' pseudo-op
+
+ The m68k `FEQU' pseudo-op is not supported.
+
+ * `NOOBJ' pseudo-op
+
+ The m68k `NOOBJ' pseudo-op is not supported.
+
+ * `OPT' branch control options
+
+ The m68k `OPT' branch control options--`B', `BRS', `BRB', `BRL',
+ and `BRW'--are ignored. `as' automatically relaxes all branches,
+ whether forward or backward, to an appropriate size, so these
+ options serve no purpose.
+
+ * `OPT' list control options
+
+ The following m68k `OPT' list control options are ignored: `C',
+ `CEX', `CL', `CRE', `E', `G', `I', `M', `MEX', `MC', `MD', `X'.
+
+ * other `OPT' options
+
+ The following m68k `OPT' options are ignored: `NEST', `O', `OLD',
+ `OP', `P', `PCO', `PCR', `PCS', `R'.
+
+ * `OPT' `D' option is default
+
+ The m68k `OPT' `D' option is the default, unlike the MRI assembler.
+ `OPT NOD' may be used to turn it off.
+
+ * `XREF' pseudo-op.
+
+ The m68k `XREF' pseudo-op is ignored.
+
+ * `.debug' pseudo-op
+
+ The i960 `.debug' pseudo-op is not supported.
+
+ * `.extended' pseudo-op
+
+ The i960 `.extended' pseudo-op is not supported.
+
+ * `.list' pseudo-op.
+
+ The various options of the i960 `.list' pseudo-op are not
+ supported.
+
+ * `.optimize' pseudo-op
+
+ The i960 `.optimize' pseudo-op is not supported.
+
+ * `.output' pseudo-op
+
+ The i960 `.output' pseudo-op is not supported.
+
+ * `.setreal' pseudo-op
+
+ The i960 `.setreal' pseudo-op is not supported.

+2.10 Dependency Tracking: `--MD'
+================================
+
+`as' can generate a dependency file for the file it creates. This file
+consists of a single rule suitable for `make' describing the
+dependencies of the main source file.
+
+ The rule is written to the file named in its argument.
+
+ This feature is used in the automatic updating of makefiles.
+
+
+File: as.info, Node: o, Next: R, Prev: MD, Up: Invoking
+
+2.11 Name the Object File: `-o'
+===============================
+
+There is always one object file output when you run `as'. By default
+it has the name `a.out' (or `b.out', for Intel 960 targets only). You
+use this option (which takes exactly one filename) to give the object
+file a different name.
+
+ Whatever the object file is called, `as' overwrites any existing
+file of the same name.
+
+
+File: as.info, Node: R, Next: statistics, Prev: o, Up: Invoking
+
+2.12 Join Data and Text Sections: `-R'
+======================================
+
+`-R' tells `as' to write the object file as if all data-section data
+lives in the text section. This is only done at the very last moment:
+your binary data are the same, but data section parts are relocated
+differently. The data section part of your object file is zero bytes
+long because all its bytes are appended to the text section. (*Note
+Sections and Relocation: Sections.)
+
+ When you specify `-R' it would be possible to generate shorter
+address displacements (because we do not have to cross between text and
+data section). We refrain from doing this simply for compatibility with
+older versions of `as'. In future, `-R' may work this way.
+
+ When `as' is configured for COFF or ELF output, this option is only
+useful if you use sections named `.text' and `.data'.
+
+ `-R' is not supported for any of the HPPA targets. Using `-R'
+generates a warning from `as'.
+
+
+File: as.info, Node: statistics, Next: traditional-format, Prev: R, Up: Invoking
+
+2.13 Display Assembly Statistics: `--statistics'
+================================================
+
+Use `--statistics' to display two statistics about the resources used by
+`as': the maximum amount of space allocated during the assembly (in
+bytes), and the total execution time taken for the assembly (in CPU
+seconds).
+
+
+File: as.info, Node: traditional-format, Next: v, Prev: statistics, Up: Invoking
+
+2.14 Compatible Output: `--traditional-format'
+==============================================
+
+For some targets, the output of `as' is different in some ways from the
+output of some existing assembler. This switch requests `as' to use
+the traditional format instead.
+
+ For example, it disables the exception frame optimizations which
+`as' normally does by default on `gcc' output.
+
+
+File: as.info, Node: v, Next: W, Prev: traditional-format, Up: Invoking
+
+2.15 Announce Version: `-v'
+===========================
+
+You can find out what version of as is running by including the option
+`-v' (which you can also spell as `-version') on the command line.
+
+
+File: as.info, Node: W, Next: Z, Prev: v, Up: Invoking
+
+2.16 Control Warnings: `-W', `--warn', `--no-warn', `--fatal-warnings'
+======================================================================
+
+`as' should never give a warning or error message when assembling
+compiler output. But programs written by people often cause `as' to
+give a warning that a particular assumption was made. All such
+warnings are directed to the standard error file.
+
+ If you use the `-W' and `--no-warn' options, no warnings are issued.
+This only affects the warning messages: it does not change any
+particular of how `as' assembles your file. Errors, which stop the
+assembly, are still reported.
+
+ If you use the `--fatal-warnings' option, `as' considers files that
+generate warnings to be in error.
+
+ You can switch these options off again by specifying `--warn', which
+causes warnings to be output as usual.
+
+
+File: as.info, Node: Z, Prev: W, Up: Invoking
+
+2.17 Generate Object File in Spite of Errors: `-Z'
+==================================================
+
+After an error message, `as' normally produces no output. If for some
+reason you are interested in object file output even after `as' gives
+an error message on your program, use the `-Z' option. If there are
+any errors, `as' continues anyways, and writes an object file after a
+final warning message of the form `N errors, M warnings, generating bad
+object file.'

+
+3 Syntax
+********
+
+This chapter describes the machine-independent syntax allowed in a
+source file. `as' syntax is similar to what many other assemblers use;
+it is inspired by the BSD 4.2 assembler, except that `as' does not
+assemble Vax bit-fields.

+
+
+File: as.info, Node: Preprocessing, Next: Whitespace, Up: Syntax
+
+3.1 Preprocessing
+=================
+
+The `as' internal preprocessor:
+ * adjusts and removes extra whitespace. It leaves one space or tab
+ before the keywords on a line, and turns any other whitespace on
+ the line into a single space.
+
+ * removes all comments, replacing them with a single space, or an
+ appropriate number of newlines.
+
+ * converts character constants into the appropriate numeric values.
+
+ It does not do macro processing, include file handling, or anything
+else you may get from your C compiler's preprocessor. You can do
+include file processing with the `.include' directive (*note
+`.include': Include.). You can use the GNU C compiler driver to get
+other "CPP" style preprocessing by giving the input file a `.S' suffix.
+*Note Options Controlling the Kind of Output: (gcc.info)Overall
+Options.
+
+ Excess whitespace, comments, and character constants cannot be used
+in the portions of the input text that are not preprocessed.
+
+ If the first line of an input file is `#NO_APP' or if you use the
+`-f' option, whitespace and comments are not removed from the input
+file. Within an input file, you can ask for whitespace and comment
+removal in specific portions of the by putting a line that says `#APP'
+before the text that may contain whitespace or comments, and putting a
+line that says `#NO_APP' after this text. This feature is mainly
+intend to support `asm' statements in compilers whose output is
+otherwise free of comments and whitespace.
+
+
+File: as.info, Node: Whitespace, Next: Comments, Prev: Preprocessing, Up: Syntax
+
+3.2 Whitespace
+==============
+
+"Whitespace" is one or more blanks or tabs, in any order. Whitespace
+is used to separate symbols, and to make programs neater for people to
+read. Unless within character constants (*note Character Constants:
+Characters.), any whitespace means the same as exactly one space.
+
+
+File: as.info, Node: Comments, Next: Symbol Intro, Prev: Whitespace, Up: Syntax
+
+3.3 Comments
+============
+
+There are two ways of rendering comments to `as'. In both cases the
+comment is equivalent to one space.
+
+ Anything from `/*' through the next `*/' is a comment. This means
+you may not nest these comments.
+
+ /*
+ The only way to include a newline ('\n') in a comment
+ is to use this sort of comment.
+ */
+
+ /* This sort of comment does not nest. */
+
+ Anything from a "line comment" character up to the next newline is
+considered a comment and is ignored. The line comment character is
+target specific, and some targets multiple comment characters. Some
+targets also have line comment characters that only work if they are
+the first character on a line. Some targets use a sequence of two
+characters to introduce a line comment. Some targets can also change
+their line comment characters depending upon command line options that
+have been used. For more details see the _Syntax_ section in the
+documentation for individual targets.
+
+ If the line comment character is the hash sign (`#') then it still
+has the special ability to enable and disable preprocessing (*note
+Preprocessing::) and to specify logical line numbers:
+
+ To be compatible with past assemblers, lines that begin with `#'
+have a special interpretation. Following the `#' should be an absolute
+expression (*note Expressions::): the logical line number of the _next_
+line. Then a string (*note Strings: Strings.) is allowed: if present
+it is a new logical file name. The rest of the line, if any, should be
+whitespace.
+
+ If the first non-whitespace characters on the line are not numeric,
+the line is ignored. (Just like a comment.)
+
+ # This is an ordinary comment.
+ # 42-6 "new_file_name" # New logical file name
+ # This is logical line # 36.
+ This feature is deprecated, and may disappear from future versions
+of `as'.

+
+3.4 Symbols
+===========
+
+A "symbol" is one or more characters chosen from the set of all letters
+(both upper and lower case), digits and the three characters `_.$'. On
+most machines, you can also use `$' in symbol names; exceptions are
+noted in *Note Machine Dependencies::. No symbol may begin with a
+digit. Case is significant. There is no length limit: all characters
+are significant. Multibyte characters are supported. Symbols are
+delimited by characters not in that set, or by the beginning of a file
+(since the source program must end with a newline, the end of a file is
+not a possible symbol delimiter). *Note Symbols::.
+
+
+File: as.info, Node: Statements, Next: Constants, Prev: Symbol Intro, Up: Syntax
+
+3.5 Statements
+==============
+
+A "statement" ends at a newline character (`\n') or a "line separator
+character". The line separator character is target specific and
+described in the _Syntax_ section of each target's documentation. Not
+all targets support a line separator character. The newline or line
+separator character is considered to be part of the preceding
+statement. Newlines and separators within character constants are an
+exception: they do not end statements.
+
+ It is an error to end any statement with end-of-file: the last
+character of any input file should be a newline.
+
+ An empty statement is allowed, and may include whitespace. It is
+ignored.
+
+ A statement begins with zero or more labels, optionally followed by a
+key symbol which determines what kind of statement it is. The key
+symbol determines the syntax of the rest of the statement. If the
+symbol begins with a dot `.' then the statement is an assembler
+directive: typically valid for any computer. If the symbol begins with
+a letter the statement is an assembly language "instruction": it
+assembles into a machine language instruction. Different versions of
+`as' for different computers recognize different instructions. In
+fact, the same symbol may represent a different instruction in a
+different computer's assembly language.
+
+ A label is a symbol immediately followed by a colon (`:').
+Whitespace before a label or after a colon is permitted, but you may not
+have whitespace between a label's symbol and its colon. *Note Labels::.
+
+ For HPPA targets, labels need not be immediately followed by a
+colon, but the definition of a label must begin in column zero. This
+also implies that only one label may be defined on each line.
+

+
+3.6.1 Character Constants
+-------------------------
+
+There are two kinds of character constants. A "character" stands for
+one character in one byte and its value may be used in numeric
+expressions. String constants (properly called string _literals_) are
+potentially many bytes and their values may not be used in arithmetic
+expressions.

+* Strings:: Strings
+* Chars:: Characters
+
+
+File: as.info, Node: Strings, Next: Chars, Up: Characters
+
+3.6.1.1 Strings
+...............
+
+A "string" is written between double-quotes. It may contain
+double-quotes or null characters. The way to get special characters
+into a string is to "escape" these characters: precede them with a
+backslash `\' character. For example `\\' represents one backslash:
+the first `\' is an escape which tells `as' to interpret the second
+character literally as a backslash (which prevents `as' from
+recognizing the second `\' as an escape character). The complete list
+of escapes follows.
+
+`\b'
+ Mnemonic for backspace; for ASCII this is octal code 010.
+
+`\f'
+ Mnemonic for FormFeed; for ASCII this is octal code 014.
+
+`\n'
+ Mnemonic for newline; for ASCII this is octal code 012.
+
+`\r'
+ Mnemonic for carriage-Return; for ASCII this is octal code 015.
+
+`\t'
+ Mnemonic for horizontal Tab; for ASCII this is octal code 011.
+
+`\ DIGIT DIGIT DIGIT'
+ An octal character code. The numeric code is 3 octal digits. For
+ compatibility with other Unix systems, 8 and 9 are accepted as
+ digits: for example, `\008' has the value 010, and `\009' the
+ value 011.
+
+`\`x' HEX-DIGITS...'
+ A hex character code. All trailing hex digits are combined.
+ Either upper or lower case `x' works.
+
+`\\'
+ Represents one `\' character.
+
+`\"'
+ Represents one `"' character. Needed in strings to represent this
+ character, because an unescaped `"' would end the string.
+
+`\ ANYTHING-ELSE'
+ Any other character when escaped by `\' gives a warning, but
+ assembles as if the `\' was not present. The idea is that if you
+ used an escape sequence you clearly didn't want the literal
+ interpretation of the following character. However `as' has no
+ other interpretation, so `as' knows it is giving you the wrong
+ code and warns you of the fact.
+
+ Which characters are escapable, and what those escapes represent,
+varies widely among assemblers. The current set is what we think the
+BSD 4.2 assembler recognizes, and is a subset of what most C compilers
+recognize. If you are in doubt, do not use an escape sequence.
+
+
+File: as.info, Node: Chars, Prev: Strings, Up: Characters
+
+3.6.1.2 Characters
+..................
+
+A single character may be written as a single quote immediately
+followed by that character. The same escapes apply to characters as to
+strings. So if you want to write the character backslash, you must
+write `'\\' where the first `\' escapes the second `\'. As you can
+see, the quote is an acute accent, not a grave accent. A newline
+immediately following an acute accent is taken as a literal character
+and does not count as the end of a statement. The value of a character
+constant in a numeric expression is the machine's byte-wide code for
+that character. `as' assumes your character code is ASCII: `'A' means
+65, `'B' means 66, and so on.

+3.6.2 Number Constants
+----------------------
+
+`as' distinguishes three kinds of numbers according to how they are
+stored in the target machine. _Integers_ are numbers that would fit
+into an `int' in the C language. _Bignums_ are integers, but they are
+stored in more than 32 bits. _Flonums_ are floating point numbers,
+described below.

+
+
+File: as.info, Node: Integers, Next: Bignums, Up: Numbers
+
+3.6.2.1 Integers
+................
+
+A binary integer is `0b' or `0B' followed by zero or more of the binary
+digits `01'.
+
+ An octal integer is `0' followed by zero or more of the octal digits
+(`01234567').
+
+ A decimal integer starts with a non-zero digit followed by zero or
+more digits (`0123456789').
+
+ A hexadecimal integer is `0x' or `0X' followed by one or more
+hexadecimal digits chosen from `0123456789abcdefABCDEF'.
+
+ Integers have the usual values. To denote a negative integer, use
+the prefix operator `-' discussed under expressions (*note Prefix
+Operators: Prefix Ops.).
+
+
+File: as.info, Node: Bignums, Next: Flonums, Prev: Integers, Up: Numbers
+
+3.6.2.2 Bignums
+...............
+
+A "bignum" has the same syntax and semantics as an integer except that
+the number (or its negative) takes more than 32 bits to represent in
+binary. The distinction is made because in some places integers are
+permitted while bignums are not.
+
+
+File: as.info, Node: Flonums, Prev: Bignums, Up: Numbers
+
+3.6.2.3 Flonums
+...............
+
+A "flonum" represents a floating point number. The translation is
+indirect: a decimal floating point number from the text is converted by
+`as' to a generic binary floating point number of more than sufficient
+precision. This generic floating point number is converted to a
+particular computer's floating point format (or formats) by a portion
+of `as' specialized to that computer.
+
+ A flonum is written by writing (in order)
+ * The digit `0'. (`0' is optional on the HPPA.)
+
+ * A letter, to tell `as' the rest of the number is a flonum. `e' is
+ recommended. Case is not important.
+
+ On the H8/300, Renesas / SuperH SH, and AMD 29K architectures, the
+ letter must be one of the letters `DFPRSX' (in upper or lower
+ case).
+
+ On the ARC, the letter must be one of the letters `DFRS' (in upper
+ or lower case).
+
+ On the Intel 960 architecture, the letter must be one of the
+ letters `DFT' (in upper or lower case).
+
+ On the HPPA architecture, the letter must be `E' (upper case only).
+
+ * An optional sign: either `+' or `-'.
+
+ * An optional "integer part": zero or more decimal digits.
+
+ * An optional "fractional part": `.' followed by zero or more
+ decimal digits.
+
+ * An optional exponent, consisting of:
+
+ * An `E' or `e'.
+
+ * Optional sign: either `+' or `-'.
+
+ * One or more decimal digits.
+
+
+ At least one of the integer part or the fractional part must be
+present. The floating point number has the usual base-10 value.
+
+ `as' does all processing using integers. Flonums are computed
+independently of any floating point hardware in the computer running
+`as'.

+Roughly, a section is a range of addresses, with no gaps; all data "in"
+those addresses is treated the same for some particular purpose. For
+example there may be a "read only" section.
+
+ The linker `ld' reads many object files (partial programs) and
+combines their contents to form a runnable program. When `as' emits an
+object file, the partial program is assumed to start at address 0.
+`ld' assigns the final addresses for the partial program, so that
+different partial programs do not overlap. This is actually an
+oversimplification, but it suffices to explain how `as' uses sections.
+
+ `ld' moves blocks of bytes of your program to their run-time
+addresses. These blocks slide to their run-time addresses as rigid
+units; their length does not change and neither does the order of bytes
+within them. Such a rigid unit is called a _section_. Assigning
+run-time addresses to sections is called "relocation". It includes the
+task of adjusting mentions of object-file addresses so they refer to
+the proper run-time addresses. For the H8/300, and for the Renesas /
+SuperH SH, `as' pads sections if needed to ensure they end on a word
+(sixteen bit) boundary.
+
+ An object file written by `as' has at least three sections, any of
+which may be empty. These are named "text", "data" and "bss" sections.
+
+ When it generates COFF or ELF output, `as' can also generate
+whatever other named sections you specify using the `.section'
+directive (*note `.section': Section.). If you do not use any
+directives that place output in the `.text' or `.data' sections, these
+sections still exist, but are empty.
+
+ When `as' generates SOM or ELF output for the HPPA, `as' can also
+generate whatever other named sections you specify using the `.space'
+and `.subspace' directives. See `HP9000 Series 800 Assembly Language
+Reference Manual' (HP 92432-90001) for details on the `.space' and
+`.subspace' assembler directives.
+
+ Additionally, `as' uses different names for the standard text, data,
+and bss sections when generating SOM output. Program text is placed
+into the `$CODE$' section, data into `$DATA$', and BSS into `$BSS$'.
+
+ Within the object file, the text section starts at address `0', the
+data section follows, and the bss section follows the data section.
+
+ When generating either SOM or ELF output files on the HPPA, the text
+section starts at address `0', the data section at address `0x4000000',
+and the bss section follows the data section.
+
+ To let `ld' know which data changes when the sections are relocated,
+and how to change that data, `as' also writes to the object file
+details of the relocation needed. To perform relocation `ld' must
+know, each time an address in the object file is mentioned:
+ * Where in the object file is the beginning of this reference to an
+ address?
+
+ * How long (in bytes) is this reference?
+
+ * Which section does the address refer to? What is the numeric
+ value of
+ (ADDRESS) - (START-ADDRESS OF SECTION)?
+
+ * Is the reference to an address "Program-Counter relative"?
+
+ In fact, every address `as' ever uses is expressed as
+ (SECTION) + (OFFSET INTO SECTION)
+ Further, most expressions `as' computes have this section-relative
+nature. (For some object formats, such as SOM for the HPPA, some
+expressions are symbol-relative instead.)
+
+ In this manual we use the notation {SECNAME N} to mean "offset N
+into section SECNAME."
+
+ Apart from text, data and bss sections you need to know about the
+"absolute" section. When `ld' mixes partial programs, addresses in the
+absolute section remain unchanged. For example, address `{absolute 0}'
+is "relocated" to run-time address 0 by `ld'. Although the linker
+never arranges two partial programs' data sections with overlapping
+addresses after linking, _by definition_ their absolute sections must
+overlap. Address `{absolute 239}' in one part of a program is always
+the same address when the program is running as address `{absolute
+239}' in any other part of the program.
+
+ The idea of sections is extended to the "undefined" section. Any
+address whose section is unknown at assembly time is by definition
+rendered {undefined U}--where U is filled in later. Since numbers are
+always defined, the only way to generate an undefined address is to
+mention an undefined symbol. A reference to a named common block would
+be such a symbol: its value is unknown at assembly time so it has
+section _undefined_.
+
+ By analogy the word _section_ is used to describe groups of sections
+in the linked program. `ld' puts all partial programs' text sections
+in contiguous addresses in the linked program. It is customary to
+refer to the _text section_ of a program, meaning all the addresses of
+all partial programs' text sections. Likewise for data and bss
+sections.
+
+ Some sections are manipulated by `ld'; others are invented for use
+of `as' and have no meaning except during assembly.
+
+

+
+4.2 Linker Sections
+===================
+
+`ld' deals with just four kinds of sections, summarized below.
+
+*named sections*
+*text section*
+*data section*
+ These sections hold your program. `as' and `ld' treat them as
+ separate but equal sections. Anything you can say of one section
+ is true of another. When the program is running, however, it is
+ customary for the text section to be unalterable. The text
+ section is often shared among processes: it contains instructions,
+ constants and the like. The data section of a running program is
+ usually alterable: for example, C variables would be stored in the
+ data section.
+
+*bss section*
+ This section contains zeroed bytes when your program begins
+ running. It is used to hold uninitialized variables or common
+ storage. The length of each partial program's bss section is
+ important, but because it starts out containing zeroed bytes there
+ is no need to store explicit zero bytes in the object file. The
+ bss section was invented to eliminate those explicit zeros from
+ object files.
+
+*absolute section*
+ Address 0 of this section is always "relocated" to runtime address
+ 0. This is useful if you want to refer to an address that `ld'
+ must not change when relocating. In this sense we speak of
+ absolute addresses being "unrelocatable": they do not change
+ during relocation.
+
+*undefined section*
+ This "section" is a catch-all for address references to objects
+ not in the preceding sections.
+
+ An idealized example of three relocatable sections follows. The
+example uses the traditional section names `.text' and `.data'. Memory
+addresses are on the horizontal axis.
+
+ +-----+----+--+
+ partial program # 1: |ttttt|dddd|00|
+ +-----+----+--+
+

+ seg. seg. seg.

+ partial program # 2: |TTT|DDD|000|

+
+ +--+---+-----+--+----+---+-----+~~

+
+4.3 Assembler Internal Sections
+===============================
+
+These sections are meant only for the internal use of `as'. They have
+no meaning at run-time. You do not really need to know about these
+sections for most purposes; but they can be mentioned in `as' warning
+messages, so it might be helpful to have an idea of their meanings to
+`as'. These sections are used to permit the value of every expression
+in your assembly language program to be a section-relative address.
+
+ASSEMBLER-INTERNAL-LOGIC-ERROR!
+ An internal assembler logic error has been found. This means
+ there is a bug in the assembler.
+
+expr section
+ The assembler stores complex expression internally as combinations
+ of symbols. When it needs to represent an expression as a symbol,
+ it puts it in the expr section.
+
+
+File: as.info, Node: Sub-Sections, Next: bss, Prev: As Sections, Up: Sections
+
+4.4 Sub-Sections
+================
+
+Assembled bytes conventionally fall into two sections: text and data.
+You may have separate groups of data in named sections that you want to
+end up near to each other in the object file, even though they are not
+contiguous in the assembler source. `as' allows you to use
+"subsections" for this purpose. Within each section, there can be
+numbered subsections with values from 0 to 8192. Objects assembled
+into the same subsection go into the object file together with other
+objects in the same subsection. For example, a compiler might want to
+store constants in the text section, but might not want to have them
+interspersed with the program being assembled. In this case, the
+compiler could issue a `.text 0' before each section of code being
+output, and a `.text 1' before each group of constants being output.
+
+Subsections are optional. If you do not use subsections, everything
+goes in subsection number zero.
+
+ Each subsection is zero-padded up to a multiple of four bytes.
+(Subsections may be padded a different amount on different flavors of
+`as'.)
+
+ Subsections appear in your object file in numeric order, lowest
+numbered to highest. (All this to be compatible with other people's
+assemblers.) The object file contains no representation of
+subsections; `ld' and other programs that manipulate object files see
+no trace of them. They just see all your text subsections as a text
+section, and all your data subsections as a data section.
+
+ To specify which subsection you want subsequent statements assembled
+into, use a numeric argument to specify it, in a `.text EXPRESSION' or
+a `.data EXPRESSION' statement. When generating COFF output, you can
+also use an extra subsection argument with arbitrary named sections:
+`.section NAME, EXPRESSION'. When generating ELF output, you can also
+use the `.subsection' directive (*note SubSection::) to specify a
+subsection: `.subsection EXPRESSION'. EXPRESSION should be an absolute
+expression (*note Expressions::). If you just say `.text' then `.text
+0' is assumed. Likewise `.data' means `.data 0'. Assembly begins in
+`text 0'. For instance:
+ .text 0 # The default subsection is text 0 anyway.
+ .ascii "This lives in the first text subsection. *"
+ .text 1
+ .ascii "But this lives in the second text subsection."
+ .data 0
+ .ascii "This lives in the data section,"
+ .ascii "in the first data subsection."
+ .text 0
+ .ascii "This lives in the first text section,"
+ .ascii "immediately following the asterisk (*)."
+
+ Each section has a "location counter" incremented by one for every
+byte assembled into that section. Because subsections are merely a
+convenience restricted to `as' there is no concept of a subsection
+location counter. There is no way to directly manipulate a location
+counter--but the `.align' directive changes it, and any label
+definition captures its current value. The location counter of the
+section where statements are being assembled is said to be the "active"
+location counter.
+
+
+File: as.info, Node: bss, Prev: Sub-Sections, Up: Sections
+
+4.5 bss Section
+===============
+
+The bss section is used for local common variable storage. You may
+allocate address space in the bss section, but you may not dictate data
+to load into it before your program executes. When your program starts
+running, all the contents of the bss section are zeroed bytes.
+
+ The `.lcomm' pseudo-op defines a symbol in the bss section; see
+*Note `.lcomm': Lcomm.
+
+ The `.comm' pseudo-op may be used to declare a common symbol, which
+is another form of uninitialized symbol; see *Note `.comm': Comm.
+
+ When assembling for a target which supports multiple sections, such
+as ELF or COFF, you may switch into the `.bss' section and define
+symbols as usual; see *Note `.section': Section. You may only assemble
+zero values into the section. Typically the section will only contain
+symbol definitions and `.skip' directives (*note `.skip': Skip.).
+

+
+5 Symbols
+*********
+
+Symbols are a central concept: the programmer uses symbols to name
+things, the linker uses symbols to link, and the debugger uses symbols
+to debug.
+
+ _Warning:_ `as' does not place symbols in the object file in the
+ same order they were declared. This may break some debuggers.

+
+
+File: as.info, Node: Labels, Next: Setting Symbols, Up: Symbols
+
+5.1 Labels
+==========
+
+A "label" is written as a symbol immediately followed by a colon `:'.
+The symbol then represents the current value of the active location
+counter, and is, for example, a suitable instruction operand. You are
+warned if you use the same symbol to represent two different locations:
+the first definition overrides any other definitions.
+
+ On the HPPA, the usual form for a label need not be immediately
+followed by a colon, but instead must start in column zero. Only one
+label may be defined on a single line. To work around this, the HPPA
+version of `as' also provides a special directive `.label' for defining
+labels more flexibly.
+
+
+File: as.info, Node: Setting Symbols, Next: Symbol Names, Prev: Labels, Up: Symbols
+
+5.2 Giving Symbols Other Values
+===============================
+
+A symbol can be given an arbitrary value by writing a symbol, followed
+by an equals sign `=', followed by an expression (*note Expressions::).
+This is equivalent to using the `.set' directive. *Note `.set': Set.
+In the same way, using a double equals sign `='`=' here represents an
+equivalent of the `.eqv' directive. *Note `.eqv': Eqv.
+
+ Blackfin does not support symbol assignment with `='.
+
+
+File: as.info, Node: Symbol Names, Next: Dot, Prev: Setting Symbols, Up: Symbols
+
+5.3 Symbol Names
+================
+
+Symbol names begin with a letter or with one of `._'. On most
+machines, you can also use `$' in symbol names; exceptions are noted in
+*Note Machine Dependencies::. That character may be followed by any
+string of digits, letters, dollar signs (unless otherwise noted for a
+particular target machine), and underscores.
+
+Case of letters is significant: `foo' is a different symbol name than
+`Foo'.
+
+ Multibyte characters are supported. To generate a symbol name
+containing multibyte characters enclose it within double quotes and use
+escape codes. cf *Note Strings::. Generating a multibyte symbol name
+from a label is not currently supported.
+
+ Each symbol has exactly one name. Each name in an assembly language
+program refers to exactly one symbol. You may use that symbol name any
+number of times in a program.
+
+Local Symbol Names
+------------------
+
+A local symbol is any symbol beginning with certain local label
+prefixes. By default, the local label prefix is `.L' for ELF systems or
+`L' for traditional a.out systems, but each target may have its own set
+of local label prefixes. On the HPPA local symbols begin with `L$'.
+
+ Local symbols are defined and used within the assembler, but they are
+normally not saved in object files. Thus, they are not visible when
+debugging. You may use the `-L' option (*note Include Local Symbols:
+`-L': L.) to retain the local symbols in the object files.
+
+Local Labels
+------------
+
+Local labels help compilers and programmers use names temporarily.
+They create symbols which are guaranteed to be unique over the entire
+scope of the input source code and which can be referred to by a simple
+notation. To define a local label, write a label of the form `N:'
+(where N represents any positive integer). To refer to the most recent
+previous definition of that label write `Nb', using the same number as
+when you defined the label. To refer to the next definition of a local
+label, write `Nf'--the `b' stands for "backwards" and the `f' stands
+for "forwards".
+
+ There is no restriction on how you can use these labels, and you can
+reuse them too. So that it is possible to repeatedly define the same
+local label (using the same number `N'), although you can only refer to
+the most recently defined local label of that number (for a backwards
+reference) or the next definition of a specific local label for a
+forward reference. It is also worth noting that the first 10 local
+labels (`0:'...`9:') are implemented in a slightly more efficient
+manner than the others.
+
+ Here is an example:
+
+ 1: branch 1f
+ 2: branch 1b
+ 1: branch 2f
+ 2: branch 1b
+
+ Which is the equivalent of:
+
+ label_1: branch label_3
+ label_2: branch label_1
+ label_3: branch label_4
+ label_4: branch label_3
+
+ Local label names are only a notational device. They are immediately
+transformed into more conventional symbol names before the assembler
+uses them. The symbol names are stored in the symbol table, appear in
+error messages, and are optionally emitted to the object file. The
+names are constructed using these parts:
+
+`_local label prefix_'
+ All local symbols begin with the system-specific local label
+ prefix. Normally both `as' and `ld' forget symbols that start
+ with the local label prefix. These labels are used for symbols
+ you are never intended to see. If you use the `-L' option then
+ `as' retains these symbols in the object file. If you also
+ instruct `ld' to retain these symbols, you may use them in
+ debugging.
+
+`NUMBER'
+ This is the number that was used in the local label definition.
+ So if the label is written `55:' then the number is `55'.
+
+`C-B'
+ This unusual character is included so you do not accidentally
+ invent a symbol of the same name. The character has ASCII value
+ of `\002' (control-B).
+
+`_ordinal number_'
+ This is a serial number to keep the labels distinct. The first
+ definition of `0:' gets the number `1'. The 15th definition of
+ `0:' gets the number `15', and so on. Likewise the first
+ definition of `1:' gets the number `1' and its 15th definition
+ gets `15' as well.
+
+ So for example, the first `1:' may be named `.L1C-B1', and the 44th
+`3:' may be named `.L3C-B44'.
+
+Dollar Local Labels
+-------------------
+
+`as' also supports an even more local form of local labels called
+dollar labels. These labels go out of scope (i.e., they become
+undefined) as soon as a non-local label is defined. Thus they remain
+valid for only a small region of the input source code. Normal local
+labels, by contrast, remain in scope for the entire file, or until they
+are redefined by another occurrence of the same local label.
+
+ Dollar labels are defined in exactly the same way as ordinary local
+labels, except that they have a dollar sign suffix to their numeric
+value, e.g., `55$:'.
+
+ They can also be distinguished from ordinary local labels by their
+transformed names which use ASCII character `\001' (control-A) as the
+magic character to distinguish them from ordinary labels. For example,
+the fifth definition of `6$' may be named `.L6C-A5'.

+
+5.4 The Special Dot Symbol
+==========================
+
+The special symbol `.' refers to the current address that `as' is
+assembling into. Thus, the expression `melvin: .long .' defines
+`melvin' to contain its own address. Assigning a value to `.' is
+treated the same as a `.org' directive. Thus, the expression `.=.+4'
+is the same as saying `.space 4'.
+
+
+File: as.info, Node: Symbol Attributes, Prev: Dot, Up: Symbols
+
+5.5 Symbol Attributes
+=====================
+
+Every symbol has, as well as its name, the attributes "Value" and
+"Type". Depending on output format, symbols can also have auxiliary
+attributes.
+
+ If you use a symbol without defining it, `as' assumes zero for all
+these attributes, and probably won't warn you. This makes the symbol
+an externally defined symbol, which is generally what you would want.

+
+5.5.1 Value
+-----------
+
+The value of a symbol is (usually) 32 bits. For a symbol which labels a
+location in the text, data, bss or absolute sections the value is the
+number of addresses from the start of that section to the label.
+Naturally for text, data and bss sections the value of a symbol changes
+as `ld' changes section base addresses during linking. Absolute
+symbols' values do not change during linking: that is why they are
+called absolute.
+
+ The value of an undefined symbol is treated in a special way. If it
+is 0 then the symbol is not defined in this assembler source file, and
+`ld' tries to determine its value from other files linked into the same
+program. You make this kind of symbol simply by mentioning a symbol
+name without defining it. A non-zero value represents a `.comm' common
+declaration. The value is how much common storage to reserve, in bytes
+(addresses). The symbol refers to the first address of the allocated
+storage.
+
+
+File: as.info, Node: Symbol Type, Next: a.out Symbols, Prev: Symbol Value, Up: Symbol Attributes

+5.5.2 Type
+----------
+
+The type attribute of a symbol contains relocation (section)
+information, any flag settings indicating that a symbol is external, and
+(optionally), other information for linkers and debuggers. The exact
+format depends on the object-code output format in use.

+
+An "expression" specifies an address or numeric value. Whitespace may
+precede and/or follow an expression.
+
+ The result of an expression must be an absolute number, or else an
+offset into a particular section. If an expression is not absolute,
+and there is not enough information when `as' sees the expression to
+know its section, a second pass over the source program might be
+necessary to interpret the expression--but the second pass is currently
+not implemented. `as' aborts with an error message in this situation.

+
+6.2.1 Arguments
+---------------
+
+"Arguments" are symbols, numbers or subexpressions. In other contexts
+arguments are sometimes called "arithmetic operands". In this manual,
+to avoid confusing them with the "instruction operands" of the machine
+language, we use the term "argument" to refer to parts of expressions
+only, reserving the word "operand" to refer only to machine instruction
+operands.
+
+ Symbols are evaluated to yield {SECTION NNN} where SECTION is one of
+text, data, bss, absolute, or undefined. NNN is a signed, 2's
+complement 32 bit integer.
+
+ Numbers are usually integers.
+
+ A number can be a flonum or bignum. In this case, you are warned
+that only the low order 32 bits are used, and `as' pretends these 32
+bits are an integer. You may write integer-manipulating instructions
+that act on exotic constants, compatible with other assemblers.
+
+ Subexpressions are a left parenthesis `(' followed by an integer
+expression, followed by a right parenthesis `)'; or a prefix operator
+followed by an argument.
+
+
+File: as.info, Node: Operators, Next: Prefix Ops, Prev: Arguments, Up: Integer Exprs
+
+6.2.2 Operators
+---------------
+
+"Operators" are arithmetic functions, like `+' or `%'. Prefix
+operators are followed by an argument. Infix operators appear between
+their arguments. Operators may be preceded and/or followed by
+whitespace.

+
+6.2.3 Prefix Operator
+---------------------
+
+`as' has the following "prefix operators". They each take one
+argument, which must be absolute.

+"Infix operators" take two arguments, one on either side. Operators
+have precedence, but operations with equal precedence are performed left

+ "Bitwise Or Not".
+
+ 3. Low Precedence
+
+ `+'
+ "Addition". If either argument is absolute, the result has
+ the section of the other argument. You may not add together
+ arguments from different sections.
+
+ `-'
+ "Subtraction". If the right argument is absolute, the result
+ has the section of the left argument. If both arguments are
+ in the same section, the result is absolute. You may not
+ subtract arguments from different sections.
+
+ `=='
+ "Is Equal To"
+
+ `<>'
+ `!='
+ "Is Not Equal To"
+
+ `<'
+ "Is Less Than"
+
+ `>'
+ "Is Greater Than"
+
+ `>='
+ "Is Greater Than Or Equal To"
+
+ `<='
+ "Is Less Than Or Equal To"
+
+ The comparison operators can be used as infix operators. A
+ true results has a value of -1 whereas a false result has a
+ value of 0. Note, these operators perform signed
+ comparisons.
+
+ 4. Lowest Precedence
+
+ `&&'
+ "Logical And".
+
+ `||'
+ "Logical Or".
+
+ These two logical operations can be used to combine the
+ results of sub expressions. Note, unlike the comparison
+ operators a true result returns a value of 1 but a false
+ results does still return 0. Also note that the logical or
+ operator has a slightly lower precedence than logical and.
+
+
+ In short, it's only meaningful to add or subtract the _offsets_ in an
+address; you can only have a defined section in one of the two
+arguments.

+
+All assembler directives have names that begin with a period (`.').
+The rest of the name is letters, usually in lower case.

+ This chapter discusses directives that are available regardless of
+the target machine configuration for the GNU assembler. Some machine
+configurations provide additional directives. *Note Machine

+
+7.1 `.abort'
+============
+
+This directive stops the assembly immediately. It is for compatibility
+with other assemblers. The original idea was that the assembly
+language source would be piped into the assembler. If the sender of
+the source quit, it could use this directive tells `as' to quit also.
+One day `.abort' will not be supported.
+
+
+File: as.info, Node: ABORT (COFF), Next: Align, Prev: Abort, Up: Pseudo Ops
+
+7.2 `.ABORT' (COFF)
+===================
+
+When producing COFF output, `as' accepts this directive as a synonym
+for `.abort'.
+
+
+File: as.info, Node: Align, Next: Altmacro, Prev: ABORT (COFF), Up: Pseudo Ops
+
+7.3 `.align ABS-EXPR, ABS-EXPR, ABS-EXPR'
+=========================================
+
+Pad the location counter (in the current subsection) to a particular
+storage boundary. The first expression (which must be absolute) is the
+alignment required, as described below.
+
+ The second expression (also absolute) gives the fill value to be
+stored in the padding bytes. It (and the comma) may be omitted. If it
+is omitted, the padding bytes are normally zero. However, on some
+systems, if the section is marked as containing code and the fill value
+is omitted, the space is filled with no-op instructions.
+
+ The third expression is also absolute, and is also optional. If it
+is present, it is the maximum number of bytes that should be skipped by
+this alignment directive. If doing the alignment would require
+skipping more bytes than the specified maximum, then the alignment is
+not done at all. You can omit the fill value (the second argument)
+entirely by simply using two commas after the required alignment; this
+can be useful if you want the alignment to be filled with no-op
+instructions when appropriate.
+
+ The way the required alignment is specified varies from system to
+system. For the arc, hppa, i386 using ELF, i860, iq2000, m68k, or1k,
+s390, sparc, tic4x, tic80 and xtensa, the first expression is the
+alignment request in bytes. For example `.align 8' advances the
+location counter until it is a multiple of 8. If the location counter
+is already a multiple of 8, no change is needed. For the tic54x, the
+first expression is the alignment request in words.
+
+ For other systems, including ppc, i386 using a.out format, arm and
+strongarm, it is the number of low-order zero bits the location counter
+must have after advancement. For example `.align 3' advances the
+location counter until it a multiple of 8. If the location counter is
+already a multiple of 8, no change is needed.
+
+ This inconsistency is due to the different behaviors of the various
+native assemblers for these systems which GAS must emulate. GAS also
+provides `.balign' and `.p2align' directives, described later, which
+have a consistent behavior across all architectures (but are specific
+to GAS).
+
+
+File: as.info, Node: Altmacro, Next: Ascii, Prev: Align, Up: Pseudo Ops
+
+7.4 `.altmacro'
+===============
+
+Enable alternate macro mode, enabling:
+
+`LOCAL NAME [ , ... ]'
+ One additional directive, `LOCAL', is available. It is used to
+ generate a string replacement for each of the NAME arguments, and
+ replace any instances of NAME in each macro expansion. The
+ replacement string is unique in the assembly, and different for
+ each separate macro expansion. `LOCAL' allows you to write macros
+ that define symbols, without fear of conflict between separate
+ macro expansions.
+
+`String delimiters'
+ You can write strings delimited in these other ways besides
+ `"STRING"':
+
+ `'STRING''
+ You can delimit strings with single-quote characters.
+
+ `<STRING>'
+ You can delimit strings with matching angle brackets.
+
+`single-character string escape'
+ To include any single character literally in a string (even if the
+ character would otherwise have some special meaning), you can
+ prefix the character with `!' (an exclamation mark). For example,
+ you can write `<4.3 !> 5.4!!>' to get the literal text `4.3 >
+ 5.4!'.
+
+`Expression results as strings'
+ You can write `%EXPR' to evaluate the expression EXPR and use the
+ result as a string.
+
+
+File: as.info, Node: Ascii, Next: Asciz, Prev: Altmacro, Up: Pseudo Ops
+
+7.5 `.ascii "STRING"'...
+========================
+
+`.ascii' expects zero or more string literals (*note Strings::)
+separated by commas. It assembles each string (with no automatic
+trailing zero byte) into consecutive addresses.
+
+
+File: as.info, Node: Asciz, Next: Balign, Prev: Ascii, Up: Pseudo Ops
+
+7.6 `.asciz "STRING"'...
+========================
+
+`.asciz' is just like `.ascii', but each string is followed by a zero
+byte. The "z" in `.asciz' stands for "zero".
+
+
+File: as.info, Node: Balign, Next: Bundle directives, Prev: Asciz, Up: Pseudo Ops
+
+7.7 `.balign[wl] ABS-EXPR, ABS-EXPR, ABS-EXPR'
+==============================================
+
+Pad the location counter (in the current subsection) to a particular
+storage boundary. The first expression (which must be absolute) is the
+alignment request in bytes. For example `.balign 8' advances the
+location counter until it is a multiple of 8. If the location counter
+is already a multiple of 8, no change is needed.
+
+ The second expression (also absolute) gives the fill value to be
+stored in the padding bytes. It (and the comma) may be omitted. If it
+is omitted, the padding bytes are normally zero. However, on some
+systems, if the section is marked as containing code and the fill value
+is omitted, the space is filled with no-op instructions.
+
+ The third expression is also absolute, and is also optional. If it
+is present, it is the maximum number of bytes that should be skipped by
+this alignment directive. If doing the alignment would require
+skipping more bytes than the specified maximum, then the alignment is
+not done at all. You can omit the fill value (the second argument)
+entirely by simply using two commas after the required alignment; this
+can be useful if you want the alignment to be filled with no-op
+instructions when appropriate.
+
+ The `.balignw' and `.balignl' directives are variants of the
+`.balign' directive. The `.balignw' directive treats the fill pattern
+as a two byte word value. The `.balignl' directives treats the fill
+pattern as a four byte longword value. For example, `.balignw
+4,0x368d' will align to a multiple of 4. If it skips two bytes, they
+will be filled in with the value 0x368d (the exact placement of the
+bytes depends upon the endianness of the processor). If it skips 1 or
+3 bytes, the fill value is undefined.
+
+
+File: as.info, Node: Bundle directives, Next: Byte, Prev: Balign, Up: Pseudo Ops
+
+7.8 `.bundle_align_mode ABS-EXPR'
+=================================
+
+`.bundle_align_mode' enables or disables "aligned instruction bundle"
+mode. In this mode, sequences of adjacent instructions are grouped
+into fixed-sized "bundles". If the argument is zero, this mode is
+disabled (which is the default state). If the argument it not zero, it
+gives the size of an instruction bundle as a power of two (as for the
+`.p2align' directive, *note P2align::).
+
+ For some targets, it's an ABI requirement that no instruction may
+span a certain aligned boundary. A "bundle" is simply a sequence of
+instructions that starts on an aligned boundary. For example, if
+ABS-EXPR is `5' then the bundle size is 32, so each aligned chunk of 32
+bytes is a bundle. When aligned instruction bundle mode is in effect,
+no single instruction may span a boundary between bundles. If an
+instruction would start too close to the end of a bundle for the length
+of that particular instruction to fit within the bundle, then the space
+at the end of that bundle is filled with no-op instructions so the
+instruction starts in the next bundle. As a corollary, it's an error
+if any single instruction's encoding is longer than the bundle size.
+
+7.9 `.bundle_lock' and `.bundle_unlock'
+=======================================
+
+The `.bundle_lock' and directive `.bundle_unlock' directives allow
+explicit control over instruction bundle padding. These directives are
+only valid when `.bundle_align_mode' has been used to enable aligned
+instruction bundle mode. It's an error if they appear when
+`.bundle_align_mode' has not been used at all, or when the last
+directive was `.bundle_align_mode 0'.
+
+ For some targets, it's an ABI requirement that certain instructions
+may appear only as part of specified permissible sequences of multiple
+instructions, all within the same bundle. A pair of `.bundle_lock' and
+`.bundle_unlock' directives define a "bundle-locked" instruction
+sequence. For purposes of aligned instruction bundle mode, a sequence
+starting with `.bundle_lock' and ending with `.bundle_unlock' is
+treated as a single instruction. That is, the entire sequence must fit
+into a single bundle and may not span a bundle boundary. If necessary,
+no-op instructions will be inserted before the first instruction of the
+sequence so that the whole sequence starts on an aligned bundle
+boundary. It's an error if the sequence is longer than the bundle size.
+
+ For convenience when using `.bundle_lock' and `.bundle_unlock'
+inside assembler macros (*note Macro::), bundle-locked sequences may be
+nested. That is, a second `.bundle_lock' directive before the next
+`.bundle_unlock' directive has no effect except that it must be matched
+by another closing `.bundle_unlock' so that there is the same number of
+`.bundle_lock' and `.bundle_unlock' directives.
+
+
+File: as.info, Node: Byte, Next: CFI directives, Prev: Bundle directives, Up: Pseudo Ops
+
+7.10 `.byte EXPRESSIONS'
+========================
+
+`.byte' expects zero or more expressions, separated by commas. Each
+expression is assembled into the next byte.
+
+
+File: as.info, Node: CFI directives, Next: Comm, Prev: Byte, Up: Pseudo Ops
+
+7.11 `.cfi_sections SECTION_LIST'
+=================================
+
+`.cfi_sections' may be used to specify whether CFI directives should
+emit `.eh_frame' section and/or `.debug_frame' section. If
+SECTION_LIST is `.eh_frame', `.eh_frame' is emitted, if SECTION_LIST is
+`.debug_frame', `.debug_frame' is emitted. To emit both use
+`.eh_frame, .debug_frame'. The default if this directive is not used
+is `.cfi_sections .eh_frame'.
+
+7.12 `.cfi_startproc [simple]'
+==============================
+
+`.cfi_startproc' is used at the beginning of each function that should
+have an entry in `.eh_frame'. It initializes some internal data
+structures. Don't forget to close the function by `.cfi_endproc'.
+
+ Unless `.cfi_startproc' is used along with parameter `simple' it
+also emits some architecture dependent initial CFI instructions.
+
+7.13 `.cfi_endproc'
+===================
+
+`.cfi_endproc' is used at the end of a function where it closes its
+unwind entry previously opened by `.cfi_startproc', and emits it to
+`.eh_frame'.
+
+7.14 `.cfi_personality ENCODING [, EXP]'
+========================================
+
+`.cfi_personality' defines personality routine and its encoding.
+ENCODING must be a constant determining how the personality should be
+encoded. If it is 255 (`DW_EH_PE_omit'), second argument is not
+present, otherwise second argument should be a constant or a symbol
+name. When using indirect encodings, the symbol provided should be the
+location where personality can be loaded from, not the personality
+routine itself. The default after `.cfi_startproc' is
+`.cfi_personality 0xff', no personality routine.
+
+7.15 `.cfi_lsda ENCODING [, EXP]'
+=================================
+
+`.cfi_lsda' defines LSDA and its encoding. ENCODING must be a constant
+determining how the LSDA should be encoded. If it is 255
+(`DW_EH_PE_omit'), second argument is not present, otherwise second
+argument should be a constant or a symbol name. The default after
+`.cfi_startproc' is `.cfi_lsda 0xff', no LSDA.
+
+7.16 `.cfi_def_cfa REGISTER, OFFSET'
+====================================
+
+`.cfi_def_cfa' defines a rule for computing CFA as: take address from
+REGISTER and add OFFSET to it.
+
+7.17 `.cfi_def_cfa_register REGISTER'
+=====================================
+
+`.cfi_def_cfa_register' modifies a rule for computing CFA. From now on
+REGISTER will be used instead of the old one. Offset remains the same.
+
+7.18 `.cfi_def_cfa_offset OFFSET'
+=================================
+
+`.cfi_def_cfa_offset' modifies a rule for computing CFA. Register
+remains the same, but OFFSET is new. Note that it is the absolute
+offset that will be added to a defined register to compute CFA address.
+
+7.19 `.cfi_adjust_cfa_offset OFFSET'
+====================================
+
+Same as `.cfi_def_cfa_offset' but OFFSET is a relative value that is
+added/substracted from the previous offset.
+
+7.20 `.cfi_offset REGISTER, OFFSET'
+===================================
+
+Previous value of REGISTER is saved at offset OFFSET from CFA.
+
+7.21 `.cfi_rel_offset REGISTER, OFFSET'
+=======================================
+
+Previous value of REGISTER is saved at offset OFFSET from the current
+CFA register. This is transformed to `.cfi_offset' using the known
+displacement of the CFA register from the CFA. This is often easier to
+use, because the number will match the code it's annotating.
+
+7.22 `.cfi_register REGISTER1, REGISTER2'
+=========================================
+
+Previous value of REGISTER1 is saved in register REGISTER2.
+
+7.23 `.cfi_restore REGISTER'
+============================
+
+`.cfi_restore' says that the rule for REGISTER is now the same as it
+was at the beginning of the function, after all initial instruction
+added by `.cfi_startproc' were executed.
+
+7.24 `.cfi_undefined REGISTER'
+==============================
+
+From now on the previous value of REGISTER can't be restored anymore.
+
+7.25 `.cfi_same_value REGISTER'
+===============================
+
+Current value of REGISTER is the same like in the previous frame, i.e.
+no restoration needed.
+
+7.26 `.cfi_remember_state',
+===========================
+
+First save all current rules for all registers by `.cfi_remember_state',
+then totally screw them up by subsequent `.cfi_*' directives and when
+everything is hopelessly bad, use `.cfi_restore_state' to restore the
+previous saved state.
+
+7.27 `.cfi_return_column REGISTER'
+==================================
+
+Change return column REGISTER, i.e. the return address is either
+directly in REGISTER or can be accessed by rules for REGISTER.
+
+7.28 `.cfi_signal_frame'
+========================
+
+Mark current function as signal trampoline.
+
+7.29 `.cfi_window_save'
+=======================
+
+SPARC register window has been saved.
+
+7.30 `.cfi_escape' EXPRESSION[, ...]
+====================================
+
+Allows the user to add arbitrary bytes to the unwind info. One might
+use this to add OS-specific CFI opcodes, or generic CFI opcodes that
+GAS does not yet support.
+
+7.31 `.cfi_val_encoded_addr REGISTER, ENCODING, LABEL'
+======================================================
+
+The current value of REGISTER is LABEL. The value of LABEL will be
+encoded in the output file according to ENCODING; see the description
+of `.cfi_personality' for details on this encoding.
+
+ The usefulness of equating a register to a fixed label is probably
+limited to the return address register. Here, it can be useful to mark
+a code segment that has only one return address which is reached by a
+direct branch and no copy of the return address exists in memory or
+another register.
+
+
+File: as.info, Node: Comm, Next: Data, Prev: CFI directives, Up: Pseudo Ops
+
+7.32 `.comm SYMBOL , LENGTH '
+=============================
+
+`.comm' declares a common symbol named SYMBOL. When linking, a common
+symbol in one object file may be merged with a defined or common symbol
+of the same name in another object file. If `ld' does not see a
+definition for the symbol-just one or more common symbols-then it will
+allocate LENGTH bytes of uninitialized memory. LENGTH must be an
+absolute expression. If `ld' sees multiple common symbols with the
+same name, and they do not all have the same size, it will allocate
+space using the largest size.
+
+ When using ELF or (as a GNU extension) PE, the `.comm' directive
+takes an optional third argument. This is the desired alignment of the
+symbol, specified for ELF as a byte boundary (for example, an alignment
+of 16 means that the least significant 4 bits of the address should be
+zero), and for PE as a power of two (for example, an alignment of 5
+means aligned to a 32-byte boundary). The alignment must be an
+absolute expression, and it must be a power of two. If `ld' allocates
+uninitialized memory for the common symbol, it will use the alignment
+when placing the symbol. If no alignment is specified, `as' will set
+the alignment to the largest power of two less than or equal to the
+size of the symbol, up to a maximum of 16 on ELF, or the default
+section alignment of 4 on PE(1).
+
+ The syntax for `.comm' differs slightly on the HPPA. The syntax is
+`SYMBOL .comm, LENGTH'; SYMBOL is optional.
+
+ ---------- Footnotes ----------
+
+ (1) This is not the same as the executable image file alignment
+controlled by `ld''s `--section-alignment' option; image file sections
+in PE are aligned to multiples of 4096, which is far too large an
+alignment for ordinary variables. It is rather the default alignment
+for (non-debug) sections within object (`*.o') files, which are less
+strictly aligned.
+
+
+File: as.info, Node: Data, Next: Def, Prev: Comm, Up: Pseudo Ops
+
+7.33 `.data SUBSECTION'
+=======================
+
+`.data' tells `as' to assemble the following statements onto the end of
+the data subsection numbered SUBSECTION (which is an absolute
+expression). If SUBSECTION is omitted, it defaults to zero.
+
+
+File: as.info, Node: Def, Next: Desc, Prev: Data, Up: Pseudo Ops
+
+7.34 `.def NAME'
+================
+
+Begin defining debugging information for a symbol NAME; the definition
+extends until the `.endef' directive is encountered.
+
+
+File: as.info, Node: Desc, Next: Dim, Prev: Def, Up: Pseudo Ops
+
+7.35 `.desc SYMBOL, ABS-EXPRESSION'
+===================================
+
+This directive sets the descriptor of the symbol (*note Symbol
+Attributes::) to the low 16 bits of an absolute expression.
+
+ The `.desc' directive is not available when `as' is configured for
+COFF output; it is only for `a.out' or `b.out' object format. For the
+sake of compatibility, `as' accepts it, but produces no output, when
+configured for COFF.
+
+
+File: as.info, Node: Dim, Next: Double, Prev: Desc, Up: Pseudo Ops
+
+7.36 `.dim'
+===========
+
+This directive is generated by compilers to include auxiliary debugging
+information in the symbol table. It is only permitted inside
+`.def'/`.endef' pairs.
+
+
+File: as.info, Node: Double, Next: Eject, Prev: Dim, Up: Pseudo Ops
+
+7.37 `.double FLONUMS'
+======================
+
+`.double' expects zero or more flonums, separated by commas. It
+assembles floating point numbers. The exact kind of floating point
+numbers emitted depends on how `as' is configured. *Note Machine
+Dependencies::.
+
+
+File: as.info, Node: Eject, Next: Else, Prev: Double, Up: Pseudo Ops

+=============
+
+Force a page break at this point, when generating assembly listings.
+
+
+File: as.info, Node: Else, Next: Elseif, Prev: Eject, Up: Pseudo Ops
+
+7.39 `.else'
+============
+
+`.else' is part of the `as' support for conditional assembly; see *Note
+`.if': If. It marks the beginning of a section of code to be assembled
+if the condition for the preceding `.if' was false.
+
+
+File: as.info, Node: Elseif, Next: End, Prev: Else, Up: Pseudo Ops
+
+7.40 `.elseif'
+==============
+

+`.end' marks the end of the assembly file. `as' does not process
+anything in the file past the `.end' directive.
+
+
+File: as.info, Node: Endef, Next: Endfunc, Prev: End, Up: Pseudo Ops
+
+7.42 `.endef'
+=============
+
+This directive flags the end of a symbol definition begun with `.def'.
+
+
+File: as.info, Node: Endfunc, Next: Endif, Prev: Endef, Up: Pseudo Ops
+
+7.43 `.endfunc'
+===============
+
+`.endfunc' marks the end of a function specified with `.func'.
+
+
+File: as.info, Node: Endif, Next: Equ, Prev: Endfunc, Up: Pseudo Ops
+
+7.44 `.endif'
+=============
+
+`.endif' is part of the `as' support for conditional assembly; it marks
+the end of a block of code that is only assembled conditionally. *Note
+`.if': If.
+
+
+File: as.info, Node: Equ, Next: Equiv, Prev: Endif, Up: Pseudo Ops
+
+7.45 `.equ SYMBOL, EXPRESSION'
+==============================
+
+This directive sets the value of SYMBOL to EXPRESSION. It is
+synonymous with `.set'; see *Note `.set': Set.
+
+ The syntax for `equ' on the HPPA is `SYMBOL .equ EXPRESSION'.
+
+ The syntax for `equ' on the Z80 is `SYMBOL equ EXPRESSION'. On the
+Z80 it is an eror if SYMBOL is already defined, but the symbol is not
+protected from later redefinition. Compare *Note Equiv::.
+
+
+File: as.info, Node: Equiv, Next: Eqv, Prev: Equ, Up: Pseudo Ops
+
+7.46 `.equiv SYMBOL, EXPRESSION'
+================================
+
+The `.equiv' directive is like `.equ' and `.set', except that the
+assembler will signal an error if SYMBOL is already defined. Note a
+symbol which has been referenced but not actually defined is considered
+to be undefined.
+
+ Except for the contents of the error message, this is roughly
+equivalent to
+ .ifdef SYM
+ .err
+ .endif
+ .equ SYM,VAL
+ plus it protects the symbol from later redefinition.
+
+
+File: as.info, Node: Eqv, Next: Err, Prev: Equiv, Up: Pseudo Ops
+
+7.47 `.eqv SYMBOL, EXPRESSION'
+==============================
+
+The `.eqv' directive is like `.equiv', but no attempt is made to
+evaluate the expression or any part of it immediately. Instead each
+time the resulting symbol is used in an expression, a snapshot of its
+current value is taken.
+
+
+File: as.info, Node: Err, Next: Error, Prev: Eqv, Up: Pseudo Ops
+
+7.48 `.err'
+===========
+
+If `as' assembles a `.err' directive, it will print an error message
+and, unless the `-Z' option was used, it will not generate an object
+file. This can be used to signal an error in conditionally compiled
+code.
+
+
+File: as.info, Node: Error, Next: Exitm, Prev: Err, Up: Pseudo Ops
+
+7.49 `.error "STRING"'
+======================
+
+Similarly to `.err', this directive emits an error, but you can specify
+a string that will be emitted as the error message. If you don't
+specify the message, it defaults to `".error directive invoked in
+source file"'. *Note Error and Warning Messages: Errors.
+
+ .error "This code has not been assembled and tested."
+
+
+File: as.info, Node: Exitm, Next: Extern, Prev: Error, Up: Pseudo Ops
+
+7.50 `.exitm'
+=============
+
+Exit early from the current macro definition. *Note Macro::.
+
+
+File: as.info, Node: Extern, Next: Fail, Prev: Exitm, Up: Pseudo Ops
+
+7.51 `.extern'
+==============
+
+`.extern' is accepted in the source program--for compatibility with
+other assemblers--but it is ignored. `as' treats all undefined symbols
+as external.
+
+
+File: as.info, Node: Fail, Next: File, Prev: Extern, Up: Pseudo Ops
+
+7.52 `.fail EXPRESSION'
+=======================
+
+Generates an error or a warning. If the value of the EXPRESSION is 500
+or more, `as' will print a warning message. If the value is less than
+500, `as' will print an error message. The message will include the
+value of EXPRESSION. This can occasionally be useful inside complex
+nested macros or conditional assembly.
+
+
+File: as.info, Node: File, Next: Fill, Prev: Fail, Up: Pseudo Ops
+
+7.53 `.file'
+============
+
+There are two different versions of the `.file' directive. Targets
+that support DWARF2 line number information use the DWARF2 version of
+`.file'. Other targets use the default version.
+
+Default Version
+---------------
+
+This version of the `.file' directive tells `as' that we are about to
+start a new logical file. The syntax is:
+
+ .file STRING
+
+ STRING is the new file name. In general, the filename is recognized
+whether or not it is surrounded by quotes `"'; but if you wish to
+specify an empty file name, you must give the quotes-`""'. This
+statement may go away in future: it is only recognized to be compatible
+with old `as' programs.
+
+DWARF2 Version
+--------------
+
+When emitting DWARF2 line number information, `.file' assigns filenames
+to the `.debug_line' file name table. The syntax is:
+
+ .file FILENO FILENAME
+
+ The FILENO operand should be a unique positive integer to use as the
+index of the entry in the table. The FILENAME operand is a C string
+literal.
+
+ The detail of filename indices is exposed to the user because the
+filename table is shared with the `.debug_info' section of the DWARF2
+debugging information, and thus the user must know the exact indices
+that table entries will have.
+
+
+File: as.info, Node: Fill, Next: Float, Prev: File, Up: Pseudo Ops
+
+7.54 `.fill REPEAT , SIZE , VALUE'
+==================================
+
+REPEAT, SIZE and VALUE are absolute expressions. This emits REPEAT
+copies of SIZE bytes. REPEAT may be zero or more. SIZE may be zero or
+more, but if it is more than 8, then it is deemed to have the value 8,
+compatible with other people's assemblers. The contents of each REPEAT
+bytes is taken from an 8-byte number. The highest order 4 bytes are
+zero. The lowest order 4 bytes are VALUE rendered in the byte-order of
+an integer on the computer `as' is assembling for. Each SIZE bytes in
+a repetition is taken from the lowest order SIZE bytes of this number.
+Again, this bizarre behavior is compatible with other people's
+assemblers.
+
+ SIZE and VALUE are optional. If the second comma and VALUE are
+absent, VALUE is assumed zero. If the first comma and following tokens
+are absent, SIZE is assumed to be 1.
+
+
+File: as.info, Node: Float, Next: Func, Prev: Fill, Up: Pseudo Ops
+
+7.55 `.float FLONUMS'
+=====================
+
+This directive assembles zero or more flonums, separated by commas. It
+has the same effect as `.single'. The exact kind of floating point
+numbers emitted depends on how `as' is configured. *Note Machine
+Dependencies::.
+
+
+File: as.info, Node: Func, Next: Global, Prev: Float, Up: Pseudo Ops
+
+7.56 `.func NAME[,LABEL]'
+=========================
+
+`.func' emits debugging information to denote function NAME, and is
+ignored unless the file is assembled with debugging enabled. Only
+`--gstabs[+]' is currently supported. LABEL is the entry point of the
+function and if omitted NAME prepended with the `leading char' is used.
+`leading char' is usually `_' or nothing, depending on the target. All
+functions are currently defined to have `void' return type. The
+function must be terminated with `.endfunc'.
+
+
+File: as.info, Node: Global, Next: Gnu_attribute, Prev: Func, Up: Pseudo Ops
+
+7.57 `.global SYMBOL', `.globl SYMBOL'
+======================================
+
+`.global' makes the symbol visible to `ld'. If you define SYMBOL in
+your partial program, its value is made available to other partial
+programs that are linked with it. Otherwise, SYMBOL takes its
+attributes from a symbol of the same name from another file linked into
+the same program.
+
+ Both spellings (`.globl' and `.global') are accepted, for
+compatibility with other assemblers.
+
+ On the HPPA, `.global' is not always enough to make it accessible to
+other partial programs. You may need the HPPA-only `.EXPORT' directive
+as well. *Note HPPA Assembler Directives: HPPA Directives.
+
+
+File: as.info, Node: Gnu_attribute, Next: Hidden, Prev: Global, Up: Pseudo Ops
+
+7.58 `.gnu_attribute TAG,VALUE'
+===============================
+
+Record a GNU object attribute for this file. *Note Object Attributes::.
+
+
+File: as.info, Node: Hidden, Next: hword, Prev: Gnu_attribute, Up: Pseudo Ops
+
+7.59 `.hidden NAMES'
+====================
+
+This is one of the ELF visibility directives. The other two are
+`.internal' (*note `.internal': Internal.) and `.protected' (*note
+`.protected': Protected.).
+
+ This directive overrides the named symbols default visibility (which
+is set by their binding: local, global or weak). The directive sets
+the visibility to `hidden' which means that the symbols are not visible
+to other components. Such symbols are always considered to be
+`protected' as well.
+
+
+File: as.info, Node: hword, Next: Ident, Prev: Hidden, Up: Pseudo Ops
+
+7.60 `.hword EXPRESSIONS'
+=========================
+
+This expects zero or more EXPRESSIONS, and emits a 16 bit number for
+each.
+
+ This directive is a synonym for `.short'; depending on the target
+architecture, it may also be a synonym for `.word'.
+
+
+File: as.info, Node: Ident, Next: If, Prev: hword, Up: Pseudo Ops
+
+7.61 `.ident'
+=============
+
+This directive is used by some assemblers to place tags in object
+files. The behavior of this directive varies depending on the target.
+When using the a.out object file format, `as' simply accepts the
+directive for source-file compatibility with existing assemblers, but
+does not emit anything for it. When using COFF, comments are emitted
+to the `.comment' or `.rdata' section, depending on the target. When
+using ELF, comments are emitted to the `.comment' section.
+
+
+File: as.info, Node: If, Next: Incbin, Prev: Ident, Up: Pseudo Ops
+
+7.62 `.if ABSOLUTE EXPRESSION'
+==============================
+
+`.if' marks the beginning of a section of code which is only considered
+part of the source program being assembled if the argument (which must
+be an ABSOLUTE EXPRESSION) is non-zero. The end of the conditional
+section of code must be marked by `.endif' (*note `.endif': Endif.);
+optionally, you may include code for the alternative condition, flagged
+by `.else' (*note `.else': Else.). If you have several conditions to
+check, `.elseif' may be used to avoid nesting blocks if/else within
+each subsequent `.else' block.
+
+ The following variants of `.if' are also supported:
+`.ifdef SYMBOL'
+ Assembles the following section of code if the specified SYMBOL
+ has been defined. Note a symbol which has been referenced but not
+ yet defined is considered to be undefined.
+
+`.ifb TEXT'
+ Assembles the following section of code if the operand is blank
+ (empty).
+
+`.ifc STRING1,STRING2'
+ Assembles the following section of code if the two strings are the
+ same. The strings may be optionally quoted with single quotes.
+ If they are not quoted, the first string stops at the first comma,
+ and the second string stops at the end of the line. Strings which
+ contain whitespace should be quoted. The string comparison is
+ case sensitive.
+
+`.ifeq ABSOLUTE EXPRESSION'
+ Assembles the following section of code if the argument is zero.
+
+`.ifeqs STRING1,STRING2'
+ Another form of `.ifc'. The strings must be quoted using double
+ quotes.
+
+`.ifge ABSOLUTE EXPRESSION'
+ Assembles the following section of code if the argument is greater
+ than or equal to zero.
+
+`.ifgt ABSOLUTE EXPRESSION'
+ Assembles the following section of code if the argument is greater
+ than zero.
+
+`.ifle ABSOLUTE EXPRESSION'
+ Assembles the following section of code if the argument is less
+ than or equal to zero.
+
+`.iflt ABSOLUTE EXPRESSION'
+ Assembles the following section of code if the argument is less
+ than zero.
+
+`.ifnb TEXT'
+ Like `.ifb', but the sense of the test is reversed: this assembles
+ the following section of code if the operand is non-blank
+ (non-empty).
+
+`.ifnc STRING1,STRING2.'
+ Like `.ifc', but the sense of the test is reversed: this assembles
+ the following section of code if the two strings are not the same.
+
+`.ifndef SYMBOL'
+`.ifnotdef SYMBOL'
+ Assembles the following section of code if the specified SYMBOL
+ has not been defined. Both spelling variants are equivalent.
+ Note a symbol which has been referenced but not yet defined is
+ considered to be undefined.
+
+`.ifne ABSOLUTE EXPRESSION'
+ Assembles the following section of code if the argument is not
+ equal to zero (in other words, this is equivalent to `.if').
+
+`.ifnes STRING1,STRING2'
+ Like `.ifeqs', but the sense of the test is reversed: this
+ assembles the following section of code if the two strings are not
+ the same.
+
+
+File: as.info, Node: Incbin, Next: Include, Prev: If, Up: Pseudo Ops
+
+7.63 `.incbin "FILE"[,SKIP[,COUNT]]'
+====================================
+
+The `incbin' directive includes FILE verbatim at the current location.
+You can control the search paths used with the `-I' command-line option
+(*note Command-Line Options: Invoking.). Quotation marks are required
+around FILE.
+
+ The SKIP argument skips a number of bytes from the start of the
+FILE. The COUNT argument indicates the maximum number of bytes to
+read. Note that the data is not aligned in any way, so it is the user's
+responsibility to make sure that proper alignment is provided both
+before and after the `incbin' directive.
+
+
+File: as.info, Node: Include, Next: Int, Prev: Incbin, Up: Pseudo Ops
+
+7.64 `.include "FILE"'
+======================
+
+This directive provides a way to include supporting files at specified
+points in your source program. The code from FILE is assembled as if
+it followed the point of the `.include'; when the end of the included
+file is reached, assembly of the original file continues. You can
+control the search paths used with the `-I' command-line option (*note
+Command-Line Options: Invoking.). Quotation marks are required around
+FILE.
+
+
+File: as.info, Node: Int, Next: Internal, Prev: Include, Up: Pseudo Ops
+
+7.65 `.int EXPRESSIONS'
+=======================
+
+Expect zero or more EXPRESSIONS, of any section, separated by commas.
+For each expression, emit a number that, at run time, is the value of
+that expression. The byte order and bit size of the number depends on
+what kind of target the assembly is for.
+
+
+File: as.info, Node: Internal, Next: Irp, Prev: Int, Up: Pseudo Ops
+
+7.66 `.internal NAMES'
+======================
+
+This is one of the ELF visibility directives. The other two are
+`.hidden' (*note `.hidden': Hidden.) and `.protected' (*note
+`.protected': Protected.).
+
+ This directive overrides the named symbols default visibility (which
+is set by their binding: local, global or weak). The directive sets
+the visibility to `internal' which means that the symbols are
+considered to be `hidden' (i.e., not visible to other components), and
+that some extra, processor specific processing must also be performed
+upon the symbols as well.
+
+
+File: as.info, Node: Irp, Next: Irpc, Prev: Internal, Up: Pseudo Ops
+
+7.67 `.irp SYMBOL,VALUES'...
+============================
+
+Evaluate a sequence of statements assigning different values to SYMBOL.
+The sequence of statements starts at the `.irp' directive, and is
+terminated by an `.endr' directive. For each VALUE, SYMBOL is set to
+VALUE, and the sequence of statements is assembled. If no VALUE is
+listed, the sequence of statements is assembled once, with SYMBOL set
+to the null string. To refer to SYMBOL within the sequence of
+statements, use \SYMBOL.
+
+ For example, assembling
+
+ .irp param,1,2,3
+ move d\param,sp@-
+ .endr
+
+ is equivalent to assembling
+
+ move d1,sp@-
+ move d2,sp@-
+ move d3,sp@-
+
+ For some caveats with the spelling of SYMBOL, see also *Note Macro::.
+
+
+File: as.info, Node: Irpc, Next: Lcomm, Prev: Irp, Up: Pseudo Ops
+
+7.68 `.irpc SYMBOL,VALUES'...
+=============================
+
+Evaluate a sequence of statements assigning different values to SYMBOL.
+The sequence of statements starts at the `.irpc' directive, and is
+terminated by an `.endr' directive. For each character in VALUE,
+SYMBOL is set to the character, and the sequence of statements is
+assembled. If no VALUE is listed, the sequence of statements is
+assembled once, with SYMBOL set to the null string. To refer to SYMBOL
+within the sequence of statements, use \SYMBOL.
+
+ For example, assembling
+
+ .irpc param,123
+ move d\param,sp@-
+ .endr
+
+ is equivalent to assembling
+
+ move d1,sp@-
+ move d2,sp@-
+ move d3,sp@-
+
+ For some caveats with the spelling of SYMBOL, see also the discussion
+at *Note Macro::.
+
+
+File: as.info, Node: Lcomm, Next: Lflags, Prev: Irpc, Up: Pseudo Ops
+
+7.69 `.lcomm SYMBOL , LENGTH'
+=============================
+
+Reserve LENGTH (an absolute expression) bytes for a local common
+denoted by SYMBOL. The section and value of SYMBOL are those of the
+new local common. The addresses are allocated in the bss section, so
+that at run-time the bytes start off zeroed. SYMBOL is not declared
+global (*note `.global': Global.), so is normally not visible to `ld'.
+
+ Some targets permit a third argument to be used with `.lcomm'. This
+argument specifies the desired alignment of the symbol in the bss
+section.
+
+ The syntax for `.lcomm' differs slightly on the HPPA. The syntax is
+`SYMBOL .lcomm, LENGTH'; SYMBOL is optional.
+
+
+File: as.info, Node: Lflags, Next: Line, Prev: Lcomm, Up: Pseudo Ops
+
+7.70 `.lflags'
+==============
+
+`as' accepts this directive, for compatibility with other assemblers,
+but ignores it.
+
+
+File: as.info, Node: Line, Next: Linkonce, Prev: Lflags, Up: Pseudo Ops
+
+7.71 `.line LINE-NUMBER'
+========================
+
+Change the logical line number. LINE-NUMBER must be an absolute
+expression. The next line has that logical line number. Therefore any
+other statements on the current line (after a statement separator
+character) are reported as on logical line number LINE-NUMBER - 1. One
+day `as' will no longer support this directive: it is recognized only
+for compatibility with existing assembler programs.
+
+Even though this is a directive associated with the `a.out' or `b.out'
+object-code formats, `as' still recognizes it when producing COFF
+output, and treats `.line' as though it were the COFF `.ln' _if_ it is
+found outside a `.def'/`.endef' pair.
+
+ Inside a `.def', `.line' is, instead, one of the directives used by
+compilers to generate auxiliary symbol information for debugging.
+
+
+File: as.info, Node: Linkonce, Next: List, Prev: Line, Up: Pseudo Ops
+
+7.72 `.linkonce [TYPE]'
+=======================
+
+Mark the current section so that the linker only includes a single copy
+of it. This may be used to include the same section in several
+different object files, but ensure that the linker will only include it
+once in the final output file. The `.linkonce' pseudo-op must be used
+for each instance of the section. Duplicate sections are detected
+based on the section name, so it should be unique.
+
+ This directive is only supported by a few object file formats; as of
+this writing, the only object file format which supports it is the
+Portable Executable format used on Windows NT.
+
+ The TYPE argument is optional. If specified, it must be one of the
+following strings. For example:
+ .linkonce same_size
+ Not all types may be supported on all object file formats.
+
+`discard'
+ Silently discard duplicate sections. This is the default.
+
+`one_only'
+ Warn if there are duplicate sections, but still keep only one copy.
+
+`same_size'
+ Warn if any of the duplicates have different sizes.
+
+`same_contents'
+ Warn if any of the duplicates do not have exactly the same
+ contents.
+
+
+File: as.info, Node: List, Next: Ln, Prev: Linkonce, Up: Pseudo Ops
+
+7.73 `.list'
+============
+
+Control (in conjunction with the `.nolist' directive) whether or not
+assembly listings are generated. These two directives maintain an
+internal counter (which is zero initially). `.list' increments the
+counter, and `.nolist' decrements it. Assembly listings are generated
+whenever the counter is greater than zero.
+
+ By default, listings are disabled. When you enable them (with the
+`-a' command line option; *note Command-Line Options: Invoking.), the
+initial value of the listing counter is one.
+
+
+File: as.info, Node: Ln, Next: Loc, Prev: List, Up: Pseudo Ops
+
+7.74 `.ln LINE-NUMBER'
+======================
+
+`.ln' is a synonym for `.line'.
+
+
+File: as.info, Node: Loc, Next: Loc_mark_labels, Prev: Ln, Up: Pseudo Ops
+
+7.75 `.loc FILENO LINENO [COLUMN] [OPTIONS]'
+============================================
+
+When emitting DWARF2 line number information, the `.loc' directive will
+add a row to the `.debug_line' line number matrix corresponding to the
+immediately following assembly instruction. The FILENO, LINENO, and
+optional COLUMN arguments will be applied to the `.debug_line' state
+machine before the row is added.
+
+ The OPTIONS are a sequence of the following tokens in any order:
+
+`basic_block'
+ This option will set the `basic_block' register in the
+ `.debug_line' state machine to `true'.
+
+`prologue_end'
+ This option will set the `prologue_end' register in the
+ `.debug_line' state machine to `true'.
+
+`epilogue_begin'
+ This option will set the `epilogue_begin' register in the
+ `.debug_line' state machine to `true'.
+
+`is_stmt VALUE'
+ This option will set the `is_stmt' register in the `.debug_line'
+ state machine to `value', which must be either 0 or 1.
+
+`isa VALUE'
+ This directive will set the `isa' register in the `.debug_line'
+ state machine to VALUE, which must be an unsigned integer.
+
+`discriminator VALUE'
+ This directive will set the `discriminator' register in the
+ `.debug_line' state machine to VALUE, which must be an unsigned
+ integer.
+

+File: as.info, Node: Loc_mark_labels, Next: Local, Prev: Loc, Up: Pseudo Ops
+
+7.76 `.loc_mark_labels ENABLE'
+==============================
+
+When emitting DWARF2 line number information, the `.loc_mark_labels'
+directive makes the assembler emit an entry to the `.debug_line' line
+number matrix with the `basic_block' register in the state machine set
+whenever a code label is seen. The ENABLE argument should be either 1
+or 0, to enable or disable this function respectively.
+

+File: as.info, Node: Local, Next: Long, Prev: Loc_mark_labels, Up: Pseudo Ops
+
+7.77 `.local NAMES'
+===================
+
+This directive, which is available for ELF targets, marks each symbol in
+the comma-separated list of `names' as a local symbol so that it will
+not be externally visible. If the symbols do not already exist, they
+will be created.
+
+ For targets where the `.lcomm' directive (*note Lcomm::) does not
+accept an alignment argument, which is the case for most ELF targets,
+the `.local' directive can be used in combination with `.comm' (*note
+Comm::) to define aligned local common data.
+
+
+File: as.info, Node: Long, Next: Macro, Prev: Local, Up: Pseudo Ops
+
+7.78 `.long EXPRESSIONS'
+========================
+
+`.long' is the same as `.int'. *Note `.int': Int.
+
+
+File: as.info, Node: Macro, Next: MRI, Prev: Long, Up: Pseudo Ops
+
+7.79 `.macro'
+=============
+
+The commands `.macro' and `.endm' allow you to define macros that
+generate assembly output. For example, this definition specifies a
+macro `sum' that puts a sequence of numbers into memory:
+
+ .macro sum from=0, to=5
+ .long \from
+ .if \to-\from
+ sum "(\from+1)",\to
+ .endif
+ .endm
+
+With that definition, `SUM 0,5' is equivalent to this assembly input:
+
+ .long 0
+ .long 1
+ .long 2
+ .long 3
+ .long 4
+ .long 5
+
+`.macro MACNAME'
+`.macro MACNAME MACARGS ...'
+ Begin the definition of a macro called MACNAME. If your macro
+ definition requires arguments, specify their names after the macro
+ name, separated by commas or spaces. You can qualify the macro
+ argument to indicate whether all invocations must specify a
+ non-blank value (through `:`req''), or whether it takes all of the
+ remaining arguments (through `:`vararg''). You can supply a
+ default value for any macro argument by following the name with
+ `=DEFLT'. You cannot define two macros with the same MACNAME
+ unless it has been subject to the `.purgem' directive (*note
+ Purgem::) between the two definitions. For example, these are all
+ valid `.macro' statements:
+
+ `.macro comm'
+ Begin the definition of a macro called `comm', which takes no
+ arguments.
+
+ `.macro plus1 p, p1'
+ `.macro plus1 p p1'
+ Either statement begins the definition of a macro called
+ `plus1', which takes two arguments; within the macro
+ definition, write `\p' or `\p1' to evaluate the arguments.
+
+ `.macro reserve_str p1=0 p2'
+ Begin the definition of a macro called `reserve_str', with two
+ arguments. The first argument has a default value, but not
+ the second. After the definition is complete, you can call
+ the macro either as `reserve_str A,B' (with `\p1' evaluating
+ to A and `\p2' evaluating to B), or as `reserve_str ,B' (with
+ `\p1' evaluating as the default, in this case `0', and `\p2'
+ evaluating to B).
+
+ `.macro m p1:req, p2=0, p3:vararg'
+ Begin the definition of a macro called `m', with at least
+ three arguments. The first argument must always have a value
+ specified, but not the second, which instead has a default
+ value. The third formal will get assigned all remaining
+ arguments specified at invocation time.
+
+ When you call a macro, you can specify the argument values
+ either by position, or by keyword. For example, `sum 9,17'
+ is equivalent to `sum to=17, from=9'.
+
+
+ Note that since each of the MACARGS can be an identifier exactly
+ as any other one permitted by the target architecture, there may be
+ occasional problems if the target hand-crafts special meanings to
+ certain characters when they occur in a special position. For
+ example, if the colon (`:') is generally permitted to be part of a
+ symbol name, but the architecture specific code special-cases it
+ when occurring as the final character of a symbol (to denote a
+ label), then the macro parameter replacement code will have no way
+ of knowing that and consider the whole construct (including the
+ colon) an identifier, and check only this identifier for being the
+ subject to parameter substitution. So for example this macro
+ definition:
+
+ .macro label l
+ \l:
+ .endm
+
+ might not work as expected. Invoking `label foo' might not create
+ a label called `foo' but instead just insert the text `\l:' into
+ the assembler source, probably generating an error about an
+ unrecognised identifier.
+
+ Similarly problems might occur with the period character (`.')
+ which is often allowed inside opcode names (and hence identifier
+ names). So for example constructing a macro to build an opcode
+ from a base name and a length specifier like this:
+
+ .macro opcode base length
+ \base.\length
+ .endm
+
+ and invoking it as `opcode store l' will not create a `store.l'
+ instruction but instead generate some kind of error as the
+ assembler tries to interpret the text `\base.\length'.
+
+ There are several possible ways around this problem:
+
+ `Insert white space'
+ If it is possible to use white space characters then this is
+ the simplest solution. eg:
+
+ .macro label l
+ \l :
+ .endm
+
+ `Use `\()''
+ The string `\()' can be used to separate the end of a macro
+ argument from the following text. eg:
+
+ .macro opcode base length
+ \base\().\length
+ .endm
+
+ `Use the alternate macro syntax mode'
+ In the alternative macro syntax mode the ampersand character
+ (`&') can be used as a separator. eg:
+
+ .altmacro
+ .macro label l
+ l&:
+ .endm
+
+ Note: this problem of correctly identifying string parameters to
+ pseudo ops also applies to the identifiers used in `.irp' (*note
+ Irp::) and `.irpc' (*note Irpc::) as well.
+
+`.endm'
+ Mark the end of a macro definition.
+
+`.exitm'
+ Exit early from the current macro definition.
+
+`\@'
+ `as' maintains a counter of how many macros it has executed in
+ this pseudo-variable; you can copy that number to your output with
+ `\@', but _only within a macro definition_.
+
+`LOCAL NAME [ , ... ]'
+ _Warning: `LOCAL' is only available if you select "alternate macro
+ syntax" with `--alternate' or `.altmacro'._ *Note `.altmacro':
+ Altmacro.

+
+7.80 `.mri VAL'
+===============
+
+If VAL is non-zero, this tells `as' to enter MRI mode. If VAL is zero,
+this tells `as' to exit MRI mode. This change affects code assembled
+until the next `.mri' directive, or until the end of the file. *Note
+MRI mode: M.

+Disable alternate macro mode. *Note Altmacro::.
+
+
+File: as.info, Node: Nolist, Next: Octa, Prev: Noaltmacro, Up: Pseudo Ops
+
+7.82 `.nolist'
+==============
+
+Control (in conjunction with the `.list' directive) whether or not
+assembly listings are generated. These two directives maintain an
+internal counter (which is zero initially). `.list' increments the
+counter, and `.nolist' decrements it. Assembly listings are generated
+whenever the counter is greater than zero.
+
+
+File: as.info, Node: Octa, Next: Offset, Prev: Nolist, Up: Pseudo Ops
+
+7.83 `.octa BIGNUMS'
+====================
+
+This directive expects zero or more bignums, separated by commas. For
+each bignum, it emits a 16-byte integer.
+
+ The term "octa" comes from contexts in which a "word" is two bytes;
+hence _octa_-word for 16 bytes.
+
+
+File: as.info, Node: Offset, Next: Org, Prev: Octa, Up: Pseudo Ops
+
+7.84 `.offset LOC'
+==================
+
+Set the location counter to LOC in the absolute section. LOC must be
+an absolute expression. This directive may be useful for defining
+symbols with absolute values. Do not confuse it with the `.org'
+directive.
+
+
+File: as.info, Node: Org, Next: P2align, Prev: Offset, Up: Pseudo Ops
+
+7.85 `.org NEW-LC , FILL'
+=========================
+
+Advance the location counter of the current section to NEW-LC. NEW-LC
+is either an absolute expression or an expression with the same section
+as the current subsection. That is, you can't use `.org' to cross
+sections: if NEW-LC has the wrong section, the `.org' directive is
+ignored. To be compatible with former assemblers, if the section of
+NEW-LC is absolute, `as' issues a warning, then pretends the section of
+NEW-LC is the same as the current subsection.
+
+ `.org' may only increase the location counter, or leave it
+unchanged; you cannot use `.org' to move the location counter backwards.
+
+ Because `as' tries to assemble programs in one pass, NEW-LC may not
+be undefined. If you really detest this restriction we eagerly await a
+chance to share your improved assembler.
+
+ Beware that the origin is relative to the start of the section, not
+to the start of the subsection. This is compatible with other people's
+assemblers.
+
+ When the location counter (of the current subsection) is advanced,
+the intervening bytes are filled with FILL which should be an absolute
+expression. If the comma and FILL are omitted, FILL defaults to zero.
+
+
+File: as.info, Node: P2align, Next: PopSection, Prev: Org, Up: Pseudo Ops
+
+7.86 `.p2align[wl] ABS-EXPR, ABS-EXPR, ABS-EXPR'
+================================================
+
+Pad the location counter (in the current subsection) to a particular
+storage boundary. The first expression (which must be absolute) is the
+number of low-order zero bits the location counter must have after
+advancement. For example `.p2align 3' advances the location counter
+until it a multiple of 8. If the location counter is already a
+multiple of 8, no change is needed.
+
+ The second expression (also absolute) gives the fill value to be
+stored in the padding bytes. It (and the comma) may be omitted. If it
+is omitted, the padding bytes are normally zero. However, on some
+systems, if the section is marked as containing code and the fill value
+is omitted, the space is filled with no-op instructions.
+
+ The third expression is also absolute, and is also optional. If it
+is present, it is the maximum number of bytes that should be skipped by
+this alignment directive. If doing the alignment would require
+skipping more bytes than the specified maximum, then the alignment is
+not done at all. You can omit the fill value (the second argument)
+entirely by simply using two commas after the required alignment; this
+can be useful if you want the alignment to be filled with no-op
+instructions when appropriate.
+
+ The `.p2alignw' and `.p2alignl' directives are variants of the
+`.p2align' directive. The `.p2alignw' directive treats the fill
+pattern as a two byte word value. The `.p2alignl' directives treats the
+fill pattern as a four byte longword value. For example, `.p2alignw
+2,0x368d' will align to a multiple of 4. If it skips two bytes, they
+will be filled in with the value 0x368d (the exact placement of the
+bytes depends upon the endianness of the processor). If it skips 1 or
+3 bytes, the fill value is undefined.

+7.87 `.popsection'
+==================
+
+This is one of the ELF section stack manipulation directives. The
+others are `.section' (*note Section::), `.subsection' (*note
+SubSection::), `.pushsection' (*note PushSection::), and `.previous'
+(*note Previous::).
+
+ This directive replaces the current section (and subsection) with
+the top section (and subsection) on the section stack. This section is
+popped off the stack.
+
+
+File: as.info, Node: Previous, Next: Print, Prev: PopSection, Up: Pseudo Ops
+
+7.88 `.previous'
+================
+
+This is one of the ELF section stack manipulation directives. The
+others are `.section' (*note Section::), `.subsection' (*note
+SubSection::), `.pushsection' (*note PushSection::), and `.popsection'
+(*note PopSection::).
+
+ This directive swaps the current section (and subsection) with most
+recently referenced section/subsection pair prior to this one. Multiple
+`.previous' directives in a row will flip between two sections (and
+their subsections). For example:
+
+ .section A
+ .subsection 1
+ .word 0x1234
+ .subsection 2
+ .word 0x5678
+ .previous
+ .word 0x9abc
+
+ Will place 0x1234 and 0x9abc into subsection 1 and 0x5678 into
+subsection 2 of section A. Whilst:
+
+ .section A
+ .subsection 1
+ # Now in section A subsection 1
+ .word 0x1234
+ .section B
+ .subsection 0
+ # Now in section B subsection 0
+ .word 0x5678
+ .subsection 1
+ # Now in section B subsection 1
+ .word 0x9abc
+ .previous
+ # Now in section B subsection 0
+ .word 0xdef0
+
+ Will place 0x1234 into section A, 0x5678 and 0xdef0 into subsection
+0 of section B and 0x9abc into subsection 1 of section B.
+
+ In terms of the section stack, this directive swaps the current
+section with the top section on the section stack.
+
+
+File: as.info, Node: Print, Next: Protected, Prev: Previous, Up: Pseudo Ops
+
+7.89 `.print STRING'
+====================
+
+`as' will print STRING on the standard output during assembly. You
+must put STRING in double quotes.
+
+
+File: as.info, Node: Protected, Next: Psize, Prev: Print, Up: Pseudo Ops
+
+7.90 `.protected NAMES'
+=======================
+
+This is one of the ELF visibility directives. The other two are
+`.hidden' (*note Hidden::) and `.internal' (*note Internal::).
+
+ This directive overrides the named symbols default visibility (which
+is set by their binding: local, global or weak). The directive sets
+the visibility to `protected' which means that any references to the
+symbols from within the components that defines them must be resolved
+to the definition in that component, even if a definition in another
+component would normally preempt this.
+
+
+File: as.info, Node: Psize, Next: Purgem, Prev: Protected, Up: Pseudo Ops
+
+7.91 `.psize LINES , COLUMNS'
+=============================
+
+Use this directive to declare the number of lines--and, optionally, the
+number of columns--to use for each page, when generating listings.
+
+ If you do not use `.psize', listings use a default line-count of 60.
+You may omit the comma and COLUMNS specification; the default width is
+200 columns.
+
+ `as' generates formfeeds whenever the specified number of lines is
+exceeded (or whenever you explicitly request one, using `.eject').
+
+ If you specify LINES as `0', no formfeeds are generated save those
+explicitly specified with `.eject'.
+
+
+File: as.info, Node: Purgem, Next: PushSection, Prev: Psize, Up: Pseudo Ops
+
+7.92 `.purgem NAME'
+===================
+
+Undefine the macro NAME, so that later uses of the string will not be
+expanded. *Note Macro::.
+
+
+File: as.info, Node: PushSection, Next: Quad, Prev: Purgem, Up: Pseudo Ops
+
+7.93 `.pushsection NAME [, SUBSECTION] [, "FLAGS"[, @TYPE[,ARGUMENTS]]]'
+========================================================================
+
+This is one of the ELF section stack manipulation directives. The
+others are `.section' (*note Section::), `.subsection' (*note
+SubSection::), `.popsection' (*note PopSection::), and `.previous'
+(*note Previous::).
+
+ This directive pushes the current section (and subsection) onto the
+top of the section stack, and then replaces the current section and
+subsection with `name' and `subsection'. The optional `flags', `type'
+and `arguments' are treated the same as in the `.section' (*note
+Section::) directive.
+
+
+File: as.info, Node: Quad, Next: Reloc, Prev: PushSection, Up: Pseudo Ops
+
+7.94 `.quad BIGNUMS'
+====================
+
+`.quad' expects zero or more bignums, separated by commas. For each
+bignum, it emits an 8-byte integer. If the bignum won't fit in 8
+bytes, it prints a warning message; and just takes the lowest order 8
+bytes of the bignum.
+
+ The term "quad" comes from contexts in which a "word" is two bytes;
+hence _quad_-word for 8 bytes.
+
+
+File: as.info, Node: Reloc, Next: Rept, Prev: Quad, Up: Pseudo Ops
+
+7.95 `.reloc OFFSET, RELOC_NAME[, EXPRESSION]'
+==============================================
+
+Generate a relocation at OFFSET of type RELOC_NAME with value
+EXPRESSION. If OFFSET is a number, the relocation is generated in the
+current section. If OFFSET is an expression that resolves to a symbol
+plus offset, the relocation is generated in the given symbol's section.
+EXPRESSION, if present, must resolve to a symbol plus addend or to an
+absolute value, but note that not all targets support an addend. e.g.
+ELF REL targets such as i386 store an addend in the section contents
+rather than in the relocation. This low level interface does not
+support addends stored in the section.
+
+
+File: as.info, Node: Rept, Next: Sbttl, Prev: Reloc, Up: Pseudo Ops
+
+7.96 `.rept COUNT'
+==================
+
+Repeat the sequence of lines between the `.rept' directive and the next
+`.endr' directive COUNT times.
+
+ For example, assembling
+
+ .rept 3
+ .long 0
+ .endr
+
+ is equivalent to assembling
+
+ .long 0
+ .long 0
+ .long 0
+
+
+File: as.info, Node: Sbttl, Next: Scl, Prev: Rept, Up: Pseudo Ops
+
+7.97 `.sbttl "SUBHEADING"'
+==========================
+
+Use SUBHEADING as the title (third line, immediately after the title
+line) when generating assembly listings.
+
+ This directive affects subsequent pages, as well as the current page
+if it appears within ten lines of the top of a page.
+
+
+File: as.info, Node: Scl, Next: Section, Prev: Sbttl, Up: Pseudo Ops
+
+7.98 `.scl CLASS'
+=================
+
+Set the storage-class value for a symbol. This directive may only be
+used inside a `.def'/`.endef' pair. Storage class may flag whether a
+symbol is static or external, or it may record further symbolic
+debugging information.
+
+
+File: as.info, Node: Section, Next: Set, Prev: Scl, Up: Pseudo Ops
+
+7.99 `.section NAME'
+====================
+
+Use the `.section' directive to assemble the following code into a
+section named NAME.
+
+ This directive is only supported for targets that actually support
+arbitrarily named sections; on `a.out' targets, for example, it is not
+accepted, even with a standard `a.out' section name.
+
+COFF Version
+------------
+
+ For COFF targets, the `.section' directive is used in one of the
+following ways:
+
+ .section NAME[, "FLAGS"]
+ .section NAME[, SUBSECTION]
+
+ If the optional argument is quoted, it is taken as flags to use for
+the section. Each flag is a single character. The following flags are
+recognized:
+`b'
+ bss section (uninitialized data)
+
+`n'
+ section is not loaded
+
+`w'
+ writable section
+
+`d'
+ data section
+
+`e'
+ exclude section from linking
+
+`r'
+ read-only section
+
+`x'
+ executable section
+
+`s'
+ shared section (meaningful for PE targets)
+
+`a'
+ ignored. (For compatibility with the ELF version)
+
+`y'
+ section is not readable (meaningful for PE targets)
+
+`0-9'
+ single-digit power-of-two section alignment (GNU extension)
+
+ If no flags are specified, the default flags depend upon the section
+name. If the section name is not recognized, the default will be for
+the section to be loaded and writable. Note the `n' and `w' flags
+remove attributes from the section, rather than adding them, so if they
+are used on their own it will be as if no flags had been specified at
+all.
+
+ If the optional argument to the `.section' directive is not quoted,
+it is taken as a subsection number (*note Sub-Sections::).
+
+ELF Version
+-----------
+
+ This is one of the ELF section stack manipulation directives. The
+others are `.subsection' (*note SubSection::), `.pushsection' (*note
+PushSection::), `.popsection' (*note PopSection::), and `.previous'
+(*note Previous::).
+
+ For ELF targets, the `.section' directive is used like this:
+
+ .section NAME [, "FLAGS"[, @TYPE[,FLAG_SPECIFIC_ARGUMENTS]]]
+
+ The optional FLAGS argument is a quoted string which may contain any
+combination of the following characters:
+`a'
+ section is allocatable
+
+`e'
+ section is excluded from executable and shared library.
+
+`w'
+ section is writable
+
+`x'
+ section is executable
+
+`M'
+ section is mergeable
+
+`S'
+ section contains zero terminated strings
+
+`G'
+ section is a member of a section group
+
+`T'
+ section is used for thread-local-storage
+
+`?'
+ section is a member of the previously-current section's group, if
+ any
+
+ The optional TYPE argument may contain one of the following
+constants:
+`@progbits'
+ section contains data
+
+`@nobits'
+ section does not contain data (i.e., section only occupies space)
+
+`@note'
+ section contains data which is used by things other than the
+ program
+
+`@init_array'
+ section contains an array of pointers to init functions
+
+`@fini_array'
+ section contains an array of pointers to finish functions
+
+`@preinit_array'
+ section contains an array of pointers to pre-init functions
+
+ Many targets only support the first three section types.
+
+ Note on targets where the `@' character is the start of a comment (eg
+ARM) then another character is used instead. For example the ARM port
+uses the `%' character.
+
+ If FLAGS contains the `M' symbol then the TYPE argument must be
+specified as well as an extra argument--ENTSIZE--like this:
+
+ .section NAME , "FLAGS"M, @TYPE, ENTSIZE
+
+ Sections with the `M' flag but not `S' flag must contain fixed size
+constants, each ENTSIZE octets long. Sections with both `M' and `S'
+must contain zero terminated strings where each character is ENTSIZE
+bytes long. The linker may remove duplicates within sections with the
+same name, same entity size and same flags. ENTSIZE must be an
+absolute expression. For sections with both `M' and `S', a string
+which is a suffix of a larger string is considered a duplicate. Thus
+`"def"' will be merged with `"abcdef"'; A reference to the first
+`"def"' will be changed to a reference to `"abcdef"+3'.
+
+ If FLAGS contains the `G' symbol then the TYPE argument must be
+present along with an additional field like this:
+
+ .section NAME , "FLAGS"G, @TYPE, GROUPNAME[, LINKAGE]
+
+ The GROUPNAME field specifies the name of the section group to which
+this particular section belongs. The optional linkage field can
+contain:
+`comdat'
+ indicates that only one copy of this section should be retained
+
+`.gnu.linkonce'
+ an alias for comdat
+
+ Note: if both the M and G flags are present then the fields for the
+Merge flag should come first, like this:
+
+ .section NAME , "FLAGS"MG, @TYPE, ENTSIZE, GROUPNAME[, LINKAGE]
+
+ If FLAGS contains the `?' symbol then it may not also contain the
+`G' symbol and the GROUPNAME or LINKAGE fields should not be present.
+Instead, `?' says to consider the section that's current before this
+directive. If that section used `G', then the new section will use `G'
+with those same GROUPNAME and LINKAGE fields implicitly. If not, then
+the `?' symbol has no effect.
+
+ If no flags are specified, the default flags depend upon the section
+name. If the section name is not recognized, the default will be for
+the section to have none of the above flags: it will not be allocated
+in memory, nor writable, nor executable. The section will contain data.
+
+ For ELF targets, the assembler supports another type of `.section'
+directive for compatibility with the Solaris assembler:
+
+ .section "NAME"[, FLAGS...]
+
+ Note that the section name is quoted. There may be a sequence of
+comma separated flags:
+`#alloc'
+ section is allocatable
+
+`#write'
+ section is writable
+
+`#execinstr'
+ section is executable
+
+`#exclude'
+ section is excluded from executable and shared library.
+
+`#tls'
+ section is used for thread local storage
+
+ This directive replaces the current section and subsection. See the
+contents of the gas testsuite directory `gas/testsuite/gas/elf' for
+some examples of how this directive and the other section stack
+directives work.

+7.100 `.set SYMBOL, EXPRESSION'
+===============================
+
+Set the value of SYMBOL to EXPRESSION. This changes SYMBOL's value and
+type to conform to EXPRESSION. If SYMBOL was flagged as external, it
+remains flagged (*note Symbol Attributes::).
+
+ You may `.set' a symbol many times in the same assembly.
+
+ If you `.set' a global symbol, the value stored in the object file
+is the last value stored into it.

+7.101 `.short EXPRESSIONS'
+==========================

+`.short' is normally the same as `.word'. *Note `.word': Word.
+
+ In some configurations, however, `.short' and `.word' generate
+numbers of different lengths. *Note Machine Dependencies::.
+
+
+File: as.info, Node: Single, Next: Size, Prev: Short, Up: Pseudo Ops
+
+7.102 `.single FLONUMS'
+=======================
+
+This directive assembles zero or more flonums, separated by commas. It
+has the same effect as `.float'. The exact kind of floating point
+numbers emitted depends on how `as' is configured. *Note Machine
+Dependencies::.

+7.103 `.size'
+=============
+
+This directive is used to set the size associated with a symbol.
+
+COFF Version
+------------
+
+ For COFF targets, the `.size' directive is only permitted inside
+`.def'/`.endef' pairs. It is used like this:
+
+ .size EXPRESSION
+
+ELF Version
+-----------
+
+ For ELF targets, the `.size' directive is used like this:
+
+ .size NAME , EXPRESSION
+
+ This directive sets the size associated with a symbol NAME. The
+size in bytes is computed from EXPRESSION which can make use of label
+arithmetic. This directive is typically used to set the size of
+function symbols.

+
+File: as.info, Node: Skip, Next: Sleb128, Prev: Size, Up: Pseudo Ops
+
+7.104 `.skip SIZE , FILL'
+=========================
+
+This directive emits SIZE bytes, each of value FILL. Both SIZE and
+FILL are absolute expressions. If the comma and FILL are omitted, FILL
+is assumed to be zero. This is the same as `.space'.
+
+
+File: as.info, Node: Sleb128, Next: Space, Prev: Skip, Up: Pseudo Ops
+
+7.105 `.sleb128 EXPRESSIONS'
+============================
+
+SLEB128 stands for "signed little endian base 128." This is a compact,
+variable length representation of numbers used by the DWARF symbolic
+debugging format. *Note `.uleb128': Uleb128.
+
+
+File: as.info, Node: Space, Next: Stab, Prev: Sleb128, Up: Pseudo Ops
+
+7.106 `.space SIZE , FILL'
+==========================
+
+This directive emits SIZE bytes, each of value FILL. Both SIZE and
+FILL are absolute expressions. If the comma and FILL are omitted, FILL
+is assumed to be zero. This is the same as `.skip'.
+
+ _Warning:_ `.space' has a completely different meaning for HPPA
+ targets; use `.block' as a substitute. See `HP9000 Series 800
+ Assembly Language Reference Manual' (HP 92432-90001) for the
+ meaning of the `.space' directive. *Note HPPA Assembler

+
+7.107 `.stabd, .stabn, .stabs'
+==============================
+
+There are three directives that begin `.stab'. All emit symbols (*note
+Symbols::), for use by symbolic debuggers. The symbols are not entered
+in the `as' hash table: they cannot be referenced elsewhere in the
+source file. Up to five fields are required:
+
+STRING
+ This is the symbol's name. It may contain any character except
+ `\000', so is more general than ordinary symbol names. Some
+ debuggers used to code arbitrarily complex structures into symbol
+ names using this field.
+
+TYPE
+ An absolute expression. The symbol's type is set to the low 8
+ bits of this expression. Any bit pattern is permitted, but `ld'
+ and debuggers choke on silly bit patterns.
+
+OTHER
+ An absolute expression. The symbol's "other" attribute is set to
+ the low 8 bits of this expression.
+
+DESC
+ An absolute expression. The symbol's descriptor is set to the low
+ 16 bits of this expression.
+
+VALUE
+ An absolute expression which becomes the symbol's value.
+
+ If a warning is detected while reading a `.stabd', `.stabn', or
+`.stabs' statement, the symbol has probably already been created; you
+get a half-formed symbol in your object file. This is compatible with
+earlier assemblers!
+
+`.stabd TYPE , OTHER , DESC'
+ The "name" of the symbol generated is not even an empty string.
+ It is a null pointer, for compatibility. Older assemblers used a
+ null pointer so they didn't waste space in object files with empty
+ strings.
+
+ The symbol's value is set to the location counter, relocatably.
+ When your program is linked, the value of this symbol is the
+ address of the location counter when the `.stabd' was assembled.
+
+`.stabn TYPE , OTHER , DESC , VALUE'
+ The name of the symbol is set to the empty string `""'.
+
+`.stabs STRING , TYPE , OTHER , DESC , VALUE'
+ All five fields are specified.

+7.108 `.string' "STR", `.string8' "STR", `.string16'
+====================================================
+
+"STR", `.string32' "STR", `.string64' "STR"
+
+ Copy the characters in STR to the object file. You may specify more
+than one string to copy, separated by commas. Unless otherwise
+specified for a particular machine, the assembler marks the end of each
+string with a 0 byte. You can use any of the escape sequences
+described in *Note Strings: Strings.
+
+ The variants `string16', `string32' and `string64' differ from the
+`string' pseudo opcode in that each 8-bit character from STR is copied
+and expanded to 16, 32 or 64 bits respectively. The expanded characters
+are stored in target endianness byte order.
+
+ Example:
+ .string32 "BYE"
+ expands to:
+ .string "B\0\0\0Y\0\0\0E\0\0\0" /* On little endian targets. */
+ .string "\0\0\0B\0\0\0Y\0\0\0E" /* On big endian targets. */

+7.109 `.struct EXPRESSION'
+==========================
+
+Switch to the absolute section, and set the section offset to
+EXPRESSION, which must be an absolute expression. You might use this
+as follows:
+ .struct 0
+ field1:
+ .struct field1 + 4
+ field2:
+ .struct field2 + 4
+ field3:
+ This would define the symbol `field1' to have the value 0, the symbol
+`field2' to have the value 4, and the symbol `field3' to have the value
+8. Assembly would be left in the absolute section, and you would need
+to use a `.section' directive of some sort to change to some other
+section before further assembly.
+
+
+File: as.info, Node: SubSection, Next: Symver, Prev: Struct, Up: Pseudo Ops
+
+7.110 `.subsection NAME'
+========================
+
+This is one of the ELF section stack manipulation directives. The
+others are `.section' (*note Section::), `.pushsection' (*note
+PushSection::), `.popsection' (*note PopSection::), and `.previous'
+(*note Previous::).
+
+ This directive replaces the current subsection with `name'. The
+current section is not changed. The replaced subsection is put onto
+the section stack in place of the then current top of stack subsection.
+
+
+File: as.info, Node: Symver, Next: Tag, Prev: SubSection, Up: Pseudo Ops
+
+7.111 `.symver'
+===============
+
+Use the `.symver' directive to bind symbols to specific version nodes
+within a source file. This is only supported on ELF platforms, and is
+typically used when assembling files to be linked into a shared library.
+There are cases where it may make sense to use this in objects to be
+bound into an application itself so as to override a versioned symbol
+from a shared library.
+
+ For ELF targets, the `.symver' directive can be used like this:
+ .symver NAME, NAME2@NODENAME
+ If the symbol NAME is defined within the file being assembled, the
+`.symver' directive effectively creates a symbol alias with the name
+NAME2@NODENAME, and in fact the main reason that we just don't try and
+create a regular alias is that the @ character isn't permitted in
+symbol names. The NAME2 part of the name is the actual name of the
+symbol by which it will be externally referenced. The name NAME itself
+is merely a name of convenience that is used so that it is possible to
+have definitions for multiple versions of a function within a single
+source file, and so that the compiler can unambiguously know which
+version of a function is being mentioned. The NODENAME portion of the
+alias should be the name of a node specified in the version script
+supplied to the linker when building a shared library. If you are
+attempting to override a versioned symbol from a shared library, then
+NODENAME should correspond to the nodename of the symbol you are trying
+to override.
+
+ If the symbol NAME is not defined within the file being assembled,
+all references to NAME will be changed to NAME2@NODENAME. If no
+reference to NAME is made, NAME2@NODENAME will be removed from the
+symbol table.
+
+ Another usage of the `.symver' directive is:
+ .symver NAME, NAME2@@NODENAME
+ In this case, the symbol NAME must exist and be defined within the
+file being assembled. It is similar to NAME2@NODENAME. The difference
+is NAME2@@NODENAME will also be used to resolve references to NAME2 by
+the linker.
+
+ The third usage of the `.symver' directive is:
+ .symver NAME, NAME2@@@NODENAME
+ When NAME is not defined within the file being assembled, it is
+treated as NAME2@NODENAME. When NAME is defined within the file being
+assembled, the symbol name, NAME, will be changed to NAME2@@NODENAME.

+7.112 `.tag STRUCTNAME'
+=======================
+
+This directive is generated by compilers to include auxiliary debugging
+information in the symbol table. It is only permitted inside
+`.def'/`.endef' pairs. Tags are used to link structure definitions in
+the symbol table with instances of those structures.
+
+
+File: as.info, Node: Text, Next: Title, Prev: Tag, Up: Pseudo Ops

+7.115 `.type'
+=============
+
+This directive is used to set the type of a symbol.
+
+COFF Version
+------------
+
+ For COFF targets, this directive is permitted only within
+`.def'/`.endef' pairs. It is used like this:
+
+ .type INT
+
+ This records the integer INT as the type attribute of a symbol table
+entry.
+
+ELF Version
+-----------
+
+ For ELF targets, the `.type' directive is used like this:
+
+ .type NAME , TYPE DESCRIPTION
+
+ This sets the type of symbol NAME to be either a function symbol or
+an object symbol. There are five different syntaxes supported for the
+TYPE DESCRIPTION field, in order to provide compatibility with various
+other assemblers.
+
+ Because some of the characters used in these syntaxes (such as `@'
+and `#') are comment characters for some architectures, some of the
+syntaxes below do not work on all architectures. The first variant
+will be accepted by the GNU assembler on all architectures so that
+variant should be used for maximum portability, if you do not need to
+assemble your code with other assemblers.
+
+ The syntaxes supported are:
+
+ .type <name> STT_<TYPE_IN_UPPER_CASE>
+ .type <name>,#<type>
+ .type <name>,@<type>
+ .type <name>,%<type>
+ .type <name>,"<type>"
+
+ The types supported are:
+
+`STT_FUNC'
+`function'
+ Mark the symbol as being a function name.
+
+`STT_GNU_IFUNC'
+`gnu_indirect_function'
+ Mark the symbol as an indirect function when evaluated during reloc
+ processing. (This is only supported on assemblers targeting GNU
+ systems).
+
+`STT_OBJECT'
+`object'
+ Mark the symbol as being a data object.
+
+`STT_TLS'
+`tls_object'
+ Mark the symbol as being a thead-local data object.
+
+`STT_COMMON'
+`common'
+ Mark the symbol as being a common data object.
+
+`STT_NOTYPE'
+`notype'
+ Does not mark the symbol in any way. It is supported just for
+ completeness.
+
+`gnu_unique_object'
+ Marks the symbol as being a globally unique data object. The
+ dynamic linker will make sure that in the entire process there is
+ just one symbol with this name and type in use. (This is only
+ supported on assemblers targeting GNU systems).
+
+
+ Note: Some targets support extra types in addition to those listed
+above.

+
+ On COFF targets other than PE, weak symbols are a GNU extension.
+This directive sets the weak attribute on the comma separated list of
+symbol `names'. If the symbols do not already exist, they will be
+created.
+
+ On the PE target, weak symbols are supported natively as weak

+File: as.info, Node: Weakref, Next: Word, Prev: Weak, Up: Pseudo Ops
+
+7.123 `.weakref ALIAS, TARGET'
+==============================
+
+This directive creates an alias to the target symbol that enables the
+symbol to be referenced with weak-symbol semantics, but without
+actually making it weak. If direct references or definitions of the
+symbol are present, then the symbol will not be weak, but if all
+references to it are through weak references, the symbol will be marked
+as weak in the symbol table.
+
+ The effect is equivalent to moving all references to the alias to a
+separate assembly source file, renaming the alias to the symbol in it,
+declaring the symbol as weak there, and running a reloadable link to
+merge the object files resulting from the assembly of the new source
+file and the old source file that had the references to the alias
+removed.
+
+ The alias itself never makes to the symbol table, and is entirely
+handled within the assembler.

+
+7.124 `.word EXPRESSIONS'
+=========================
+
+This directive expects zero or more EXPRESSIONS, of any section,
+separated by commas.
+
+ The size of the number emitted, and its byte order, depend on what
+target computer the assembly is for.
+
+ _Warning: Special Treatment to support Compilers_
+
+ Machines with a 32-bit address space, but that do less than 32-bit
+addressing, require the following special treatment. If the machine of
+interest to you does 32-bit addressing (or doesn't require it; *note
+Machine Dependencies::), you can ignore this issue.
+
+ In order to assemble compiler output into something that works, `as'
+occasionally does strange things to `.word' directives. Directives of
+the form `.word sym1-sym2' are often emitted by compilers as part of
+jump tables. Therefore, when `as' assembles a directive of the form
+`.word sym1-sym2', and the difference between `sym1' and `sym2' does
+not fit in 16 bits, `as' creates a "secondary jump table", immediately
+before the next label. This secondary jump table is preceded by a
+short-jump to the first byte after the secondary table. This
+short-jump prevents the flow of control from accidentally falling into
+the new table. Inside the table is a long-jump to `sym2'. The
+original `.word' contains `sym1' minus the address of the long-jump to
+`sym2'.
+
+ If there were several occurrences of `.word sym1-sym2' before the
+secondary jump table, all of them are adjusted. If there was a `.word
+sym3-sym4', that also did not fit in sixteen bits, a long-jump to
+`sym4' is included in the secondary jump table, and the `.word'
+directives are adjusted to contain `sym3' minus the address of the
+long-jump to `sym4'; and so on, for as many entries in the original
+jump table as necessary.

+8 Object Attributes
+*******************
+
+`as' assembles source files written for a specific architecture into
+object files for that architecture. But not all object files are alike.
+Many architectures support incompatible variations. For instance,
+floating point arguments might be passed in floating point registers if
+the object file requires hardware floating point support--or floating
+point arguments might be passed in integer registers if the object file
+supports processors with no hardware floating point unit. Or, if two
+objects are built for different generations of the same architecture,
+the combination may require the newer generation at run-time.
+
+ This information is useful during and after linking. At link time,
+`ld' can warn about incompatible object files. After link time, tools
+like `gdb' can use it to process the linked file correctly.
+
+ Compatibility information is recorded as a series of object
+attributes. Each attribute has a "vendor", "tag", and "value". The
+vendor is a string, and indicates who sets the meaning of the tag. The
+tag is an integer, and indicates what property the attribute describes.
+The value may be a string or an integer, and indicates how the
+property affects this object. Missing attributes are the same as
+attributes with a zero value or empty string value.
+
+ Object attributes were developed as part of the ABI for the ARM
+Architecture. The file format is documented in `ELF for the ARM
+Architecture'.

+
+8.1 GNU Object Attributes
+=========================
+
+The `.gnu_attribute' directive records an object attribute with vendor
+`gnu'.
+
+ Except for `Tag_compatibility', which has both an integer and a
+string for its value, GNU attributes have a string value if the tag
+number is odd and an integer value if the tag number is even. The
+second bit (`TAG & 2' is set for architecture-independent attributes
+and clear for architecture-dependent ones.
+
+8.1.1 Common GNU attributes
+---------------------------
+
+These attributes are valid on all architectures.
+
+Tag_compatibility (32)
+ The compatibility attribute takes an integer flag value and a
+ vendor name. If the flag value is 0, the file is compatible with
+ other toolchains. If it is 1, then the file is only compatible
+ with the named toolchain. If it is greater than 1, the file can
+ only be processed by other toolchains under some private
+ arrangement indicated by the flag value and the vendor name.
+
+8.1.2 MIPS Attributes
+---------------------
+
+Tag_GNU_MIPS_ABI_FP (4)
+ The floating-point ABI used by this object file. The value will
+ be:
+
+ * 0 for files not affected by the floating-point ABI.
+
+ * 1 for files using the hardware floating-point ABI with a
+ standard double-precision FPU.
+
+ * 2 for files using the hardware floating-point ABI with a
+ single-precision FPU.
+
+ * 3 for files using the software floating-point ABI.
+
+ * 4 for files using the deprecated hardware floating-point ABI
+ which used 64-bit floating-point registers, 32-bit
+ general-purpose registers and increased the number of
+ callee-saved floating-point registers.
+
+ * 5 for files using the hardware floating-point ABI with a
+ double-precision FPU with either 32-bit or 64-bit
+ floating-point registers and 32-bit general-purpose registers.
+
+ * 6 for files using the hardware floating-point ABI with 64-bit
+ floating-point registers and 32-bit general-purpose registers.
+
+ * 7 for files using the hardware floating-point ABI with 64-bit
+ floating-point registers, 32-bit general-purpose registers
+ and a rule that forbids the direct use of odd-numbered
+ single-precision floating-point registers.
+
+8.1.3 PowerPC Attributes
+------------------------
+
+Tag_GNU_Power_ABI_FP (4)
+ The floating-point ABI used by this object file. The value will
+ be:
+
+ * 0 for files not affected by the floating-point ABI.
+
+ * 1 for files using double-precision hardware floating-point
+ ABI.
+
+ * 2 for files using the software floating-point ABI.
+
+ * 3 for files using single-precision hardware floating-point
+ ABI.
+
+Tag_GNU_Power_ABI_Vector (8)
+ The vector ABI used by this object file. The value will be:
+
+ * 0 for files not affected by the vector ABI.
+
+ * 1 for files using general purpose registers to pass vectors.
+
+ * 2 for files using AltiVec registers to pass vectors.
+
+ * 3 for files using SPE registers to pass vectors.

+8.2 Defining New Object Attributes
+==================================
+
+If you want to define a new GNU object attribute, here are the places
+you will need to modify. New attributes should be discussed on the
+`binutils' mailing list.
+
+ * This manual, which is the official register of attributes.
+
+ * The header for your architecture `include/elf', to define the tag.
+
+ * The `bfd' support file for your architecture, to merge the
+ attribute and issue any appropriate link warnings.
+
+ * Test cases in `ld/testsuite' for merging and link warnings.
+
+ * `binutils/readelf.c' to display your attribute.
+
+ * GCC, if you want the compiler to mark the attribute automatically.

+9 Machine Dependent Features
+****************************
+
+The machine instruction sets are (almost by definition) different on
+each machine where `as' runs. Floating point representations vary as
+well, and `as' often supports a few additional directives or
+command-line options for compatibility with other assemblers on a
+particular platform. Finally, some versions of `as' support special
+pseudo-instructions for branch optimization.
+
+ This chapter discusses most of these differences, though it does not
+include details on any machine's instruction set. For details on that
+subject, see the hardware manufacturer's manual.

+-------------
+
+`-EB'
+ This option specifies that the output generated by the assembler
+ should be marked as being encoded for a big-endian processor.
+
+`-EL'
+ This option specifies that the output generated by the assembler
+ should be marked as being encoded for a little-endian processor.
+
+`-mabi=ABI'
+ Specify which ABI the source code uses. The recognized arguments
+ are: `ilp32' and `lp64', which decides the generated object file
+ in ELF32 and ELF64 format respectively. The default is `lp64'.
+
+`-mcpu=PROCESSOR[+EXTENSION...]'
+ This option specifies the target processor. The assembler will
+ issue an error message if an attempt is made to assemble an
+ instruction which will not execute on the target processor. The
+ following processor names are recognized: `cortex-a53',
+ `cortex-a57', `xgene1', and `xgene2'. The special name `all' may
+ be used to allow the assembler to accept instructions valid for
+ any supported processor, including all optional extensions.
+
+ In addition to the basic instruction set, the assembler can be
+ told to accept, or restrict, various extension mnemonics that
+ extend the processor. *Note AArch64 Extensions::.
+
+ If some implementations of a particular processor can have an
+ extension, then then those extensions are automatically enabled.
+ Consequently, you will not normally have to specify any additional
+ extensions.
+
+`-march=ARCHITECTURE[+EXTENSION...]'
+ This option specifies the target architecture. The assembler will
+ issue an error message if an attempt is made to assemble an
+ instruction which will not execute on the target architecture. The
+ only value for ARCHITECTURE is `armv8-a'.
+
+ If both `-mcpu' and `-march' are specified, the assembler will use
+ the setting for `-mcpu'. If neither are specified, the assembler
+ will default to `-mcpu=all'.
+
+ The architecture option can be extended with the same instruction
+ set extension options as the `-mcpu' option. Unlike `-mcpu',
+ extensions are not always enabled by default, *Note AArch64
+ Extensions::.
+
+`-mverbose-error'
+ This option enables verbose error messages for AArch64 gas. This
+ option is enabled by default.
+
+`-mno-verbose-error'
+ This option disables verbose error messages in AArch64 gas.

+9.1.2 Architecture Extensions
+-----------------------------
+
+The table below lists the permitted architecture extensions that are
+supported by the assembler and the conditions under which they are
+automatically enabled.
+
+ Multiple extensions may be specified, separated by a `+'. Extension
+mnemonics may also be removed from those the assembler accepts. This
+is done by prepending `no' to the option that adds the extension.
+Extensions that are removed must be listed after all extensions that
+have been added.
+
+ Enabling an extension that requires other extensions will
+automatically cause those extensions to be enabled. Similarly,
+disabling an extension that is required by other extensions will
+automatically cause those extensions to be disabled.
+
+Extension Minimum Enabled by Description
+ Architecture default
+----------------------------------------------------------------------------
+`crc' ARMv8-A No Enable CRC instructions.
+`crypto' ARMv8-A No Enable cryptographic extensions. This
+ implies `fp' and `simd'.
+`fp' ARMv8-A ARMv8-A or Enable floating-point extensions.
+ later
+`simd' ARMv8-A ARMv8-A or Enable Advanced SIMD extensions. This
+ later implies `fp'.

+9.1.3.1 Special Characters
+..........................
+
+The presence of a `//' on a line indicates the start of a comment that
+extends to the end of the current line. If a `#' appears as the first
+character of a line, the whole line is treated as a comment.
+
+ The `;' character can be used instead of a newline to separate
+statements.
+
+ The `#' can be optionally used to indicate immediate operands.

+
+9.1.3.3 Relocations
+...................
+
+Relocations for `MOVZ' and `MOVK' instructions can be generated by
+prefixing the label with `#:abs_g2:' etc. For example to load the
+48-bit absolute address of FOO into x0:
+
+ movz x0, #:abs_g2:foo // bits 32-47, overflow check
+ movk x0, #:abs_g1_nc:foo // bits 16-31, no overflow check
+ movk x0, #:abs_g0_nc:foo // bits 0-15, no overflow check
+
+ Relocations for `ADRP', and `ADD', `LDR' or `STR' instructions can
+be generated by prefixing the label with `:pg_hi21:' and `#:lo12:'
+respectively.
+
+ For example to use 33-bit (+/-4GB) pc-relative addressing to load
+the address of FOO into x0:
+
+ adrp x0, :pg_hi21:foo
+ add x0, x0, #:lo12:foo
+
+ Or to load the value of FOO into x0:
+
+ adrp x0, :pg_hi21:foo
+ ldr x0, [x0, #:lo12:foo]
+
+ Note that `:pg_hi21:' is optional.
+
+ adrp x0, foo
+
+ is equivalent to
+
+ adrp x0, :pg_hi21:foo

+--------------------
+
+The AArch64 architecture uses IEEE floating-point numbers.

+
+9.1.5 AArch64 Machine Directives
+--------------------------------
+
+`.bss'
+ This directive switches to the `.bss' section.
+
+`.ltorg'
+ This directive causes the current contents of the literal pool to
+ be dumped into the current section (which is assumed to be the
+ .text section) at the current location (aligned to a word
+ boundary). GAS maintains a separate literal pool for each section
+ and each sub-section. The `.ltorg' directive will only affect the
+ literal pool of the current section and sub-section. At the end
+ of assembly all remaining, un-empty literal pools will
+ automatically be dumped.
+
+ Note - older versions of GAS would dump the current literal pool
+ any time a section change occurred. This is no longer done, since
+ it prevents accurate control of the placement of literal pools.
+
+`.pool'
+ This is a synonym for .ltorg.
+
+`NAME .req REGISTER NAME'
+ This creates an alias for REGISTER NAME called NAME. For example:
+
+ foo .req w0
+
+`.unreq ALIAS-NAME'
+ This undefines a register alias which was previously defined using
+ the `req' directive. For example:
+
+ foo .req w0
+ .unreq foo
+
+ An error occurs if the name is undefined. Note - this pseudo op
+ can be used to delete builtin in register name aliases (eg 'w0').
+ This should only be done if it is really necessary.

+
+9.1.6 Opcodes
+-------------
+
+GAS implements all the standard AArch64 opcodes. It also implements
+several pseudo opcodes, including several synthetic load instructions.
+
+`LDR ='
+ ldr <register> , =<expression>
+
+ The constant expression will be placed into the nearest literal
+ pool (if it not already there) and a PC-relative LDR instruction
+ will be generated.
+

+language notation, see `ARMv8 Instruction Set Overview' available at

+9.1.7 Mapping Symbols
+---------------------
+
+The AArch64 ELF specification requires that special symbols be inserted
+into object files to mark certain features:
+
+`$x'
+ At the start of a region of code containing AArch64 instructions.
+
+`$d'
+ At the start of a region of data.

+
+9.2.1 Notes
+-----------
+
+The documentation here is primarily for the ELF object format. `as'
+also supports the ECOFF and EVAX formats, but features specific to
+these formats are not yet documented.
+
+
+File: as.info, Node: Alpha Options, Next: Alpha Syntax, Prev: Alpha Notes, Up: Alpha-Dependent
+
+9.2.2 Options
+-------------
+
+`-mCPU'
+ This option specifies the target processor. If an attempt is made
+ to assemble an instruction which will not execute on the target
+ processor, the assembler may either expand the instruction as a
+ macro or issue an error message. This option is equivalent to the
+ `.arch' directive.
+
+ The following processor names are recognized: `21064', `21064a',
+ `21066', `21068', `21164', `21164a', `21164pc', `21264', `21264a',
+ `21264b', `ev4', `ev5', `lca45', `ev5', `ev56', `pca56', `ev6',
+ `ev67', `ev68'. The special name `all' may be used to allow the
+ assembler to accept instructions valid for any Alpha processor.
+
+ In order to support existing practice in OSF/1 with respect to
+ `.arch', and existing practice within `MILO' (the Linux ARC
+ bootloader), the numbered processor names (e.g. 21064) enable the
+ processor-specific PALcode instructions, while the
+ "electro-vlasic" names (e.g. `ev4') do not.
+
+`-mdebug'
+`-no-mdebug'
+ Enables or disables the generation of `.mdebug' encapsulation for
+ stabs directives and procedure descriptors. The default is to
+ automatically enable `.mdebug' when the first stabs directive is
+ seen.
+
+`-relax'
+ This option forces all relocations to be put into the object file,
+ instead of saving space and resolving some relocations at assembly
+ time. Note that this option does not propagate all symbol
+ arithmetic into the object file, because not all symbol arithmetic
+ can be represented. However, the option can still be useful in
+ specific applications.
+
+`-replace'
+`-noreplace'
+ Enables or disables the optimization of procedure calls, both at
+ assemblage and at link time. These options are only available for
+ VMS targets and `-replace' is the default. See section 1.4.1 of
+ the OpenVMS Linker Utility Manual.
+
+`-g'
+ This option is used when the compiler generates debug information.
+ When `gcc' is using `mips-tfile' to generate debug information
+ for ECOFF, local labels must be passed through to the object file.
+ Otherwise this option has no effect.
+
+`-GSIZE'
+ A local common symbol larger than SIZE is placed in `.bss', while
+ smaller symbols are placed in `.sbss'.
+
+`-F'
+`-32addr'
+ These options are ignored for backward compatibility.

+
+9.2.3.1 Special Characters
+..........................
+
+`#' is the line comment character. Note that if `#' is the first
+character on a line then it can also be a logical line number directive
+(*note Comments::) or a preprocessor control command (*note
+Preprocessing::).
+
+ `;' can be used instead of a newline to separate statements.

+
+9.2.3.2 Register Names
+......................
+
+The 32 integer registers are referred to as `$N' or `$rN'. In
+addition, registers 15, 28, 29, and 30 may be referred to by the
+symbols `$fp', `$at', `$gp', and `$sp' respectively.
+
+ The 32 floating-point registers are referred to as `$fN'.
+
+
+File: as.info, Node: Alpha-Relocs, Prev: Alpha-Regs, Up: Alpha Syntax
+
+9.2.3.3 Relocations
+...................
+
+Some of these relocations are available for ECOFF, but mostly only for
+ELF. They are modeled after the relocation format introduced in
+Digital Unix 4.0, but there are additions.
+
+ The format is `!TAG' or `!TAG!NUMBER' where TAG is the name of the
+relocation. In some cases NUMBER is used to relate specific
+instructions.
+
+ The relocation is placed at the end of the instruction like so:
+
+ ldah $0,a($29) !gprelhigh
+ lda $0,a($0) !gprellow
+ ldq $1,b($29) !literal!100
+ ldl $2,0($1) !lituse_base!100
+
+`!literal'
+`!literal!N'
+ Used with an `ldq' instruction to load the address of a symbol
+ from the GOT.
+
+ A sequence number N is optional, and if present is used to pair
+ `lituse' relocations with this `literal' relocation. The `lituse'
+ relocations are used by the linker to optimize the code based on
+ the final location of the symbol.
+
+ Note that these optimizations are dependent on the data flow of the
+ program. Therefore, if _any_ `lituse' is paired with a `literal'
+ relocation, then _all_ uses of the register set by the `literal'
+ instruction must also be marked with `lituse' relocations. This
+ is because the original `literal' instruction may be deleted or
+ transformed into another instruction.
+
+ Also note that there may be a one-to-many relationship between
+ `literal' and `lituse', but not a many-to-one. That is, if there
+ are two code paths that load up the same address and feed the
+ value to a single use, then the use may not use a `lituse'
+ relocation.
+
+`!lituse_base!N'
+ Used with any memory format instruction (e.g. `ldl') to indicate
+ that the literal is used for an address load. The offset field of
+ the instruction must be zero. During relaxation, the code may be
+ altered to use a gp-relative load.
+
+`!lituse_jsr!N'
+ Used with a register branch format instruction (e.g. `jsr') to
+ indicate that the literal is used for a call. During relaxation,
+ the code may be altered to use a direct branch (e.g. `bsr').
+
+`!lituse_jsrdirect!N'
+ Similar to `lituse_jsr', but also that this call cannot be vectored
+ through a PLT entry. This is useful for functions with special
+ calling conventions which do not allow the normal call-clobbered
+ registers to be clobbered.
+
+`!lituse_bytoff!N'
+ Used with a byte mask instruction (e.g. `extbl') to indicate that
+ only the low 3 bits of the address are relevant. During
+ relaxation, the code may be altered to use an immediate instead of
+ a register shift.
+
+`!lituse_addr!N'
+ Used with any other instruction to indicate that the original
+ address is in fact used, and the original `ldq' instruction may
+ not be altered or deleted. This is useful in conjunction with
+ `lituse_jsr' to test whether a weak symbol is defined.
+
+ ldq $27,foo($29) !literal!1
+ beq $27,is_undef !lituse_addr!1
+ jsr $26,($27),foo !lituse_jsr!1
+
+`!lituse_tlsgd!N'
+ Used with a register branch format instruction to indicate that the
+ literal is the call to `__tls_get_addr' used to compute the
+ address of the thread-local storage variable whose descriptor was
+ loaded with `!tlsgd!N'.
+
+`!lituse_tlsldm!N'
+ Used with a register branch format instruction to indicate that the
+ literal is the call to `__tls_get_addr' used to compute the
+ address of the base of the thread-local storage block for the
+ current module. The descriptor for the module must have been
+ loaded with `!tlsldm!N'.
+
+`!gpdisp!N'
+ Used with `ldah' and `lda' to load the GP from the current
+ address, a-la the `ldgp' macro. The source register for the
+ `ldah' instruction must contain the address of the `ldah'
+ instruction. There must be exactly one `lda' instruction paired
+ with the `ldah' instruction, though it may appear anywhere in the
+ instruction stream. The immediate operands must be zero.
+
+ bsr $26,foo
+ ldah $29,0($26) !gpdisp!1
+ lda $29,0($29) !gpdisp!1
+
+`!gprelhigh'
+ Used with an `ldah' instruction to add the high 16 bits of a
+ 32-bit displacement from the GP.
+
+`!gprellow'
+ Used with any memory format instruction to add the low 16 bits of a
+ 32-bit displacement from the GP.
+
+`!gprel'
+ Used with any memory format instruction to add a 16-bit
+ displacement from the GP.
+
+`!samegp'
+ Used with any branch format instruction to skip the GP load at the
+ target address. The referenced symbol must have the same GP as the
+ source object file, and it must be declared to either not use `$27'
+ or perform a standard GP load in the first two instructions via the
+ `.prologue' directive.
+
+`!tlsgd'
+`!tlsgd!N'
+ Used with an `lda' instruction to load the address of a TLS
+ descriptor for a symbol in the GOT.
+
+ The sequence number N is optional, and if present it used to pair
+ the descriptor load with both the `literal' loading the address of
+ the `__tls_get_addr' function and the `lituse_tlsgd' marking the
+ call to that function.
+
+ For proper relaxation, both the `tlsgd', `literal' and `lituse'
+ relocations must be in the same extended basic block. That is,
+ the relocation with the lowest address must be executed first at
+ runtime.
+
+`!tlsldm'
+`!tlsldm!N'
+ Used with an `lda' instruction to load the address of a TLS
+ descriptor for the current module in the GOT.
+
+ Similar in other respects to `tlsgd'.
+
+`!gotdtprel'
+ Used with an `ldq' instruction to load the offset of the TLS
+ symbol within its module's thread-local storage block. Also known
+ as the dynamic thread pointer offset or dtp-relative offset.
+
+`!dtprelhi'
+`!dtprello'
+`!dtprel'
+ Like `gprel' relocations except they compute dtp-relative offsets.
+
+`!gottprel'
+ Used with an `ldq' instruction to load the offset of the TLS
+ symbol from the thread pointer. Also known as the tp-relative
+ offset.
+
+`!tprelhi'
+`!tprello'
+`!tprel'
+ Like `gprel' relocations except they compute tp-relative offsets.

+9.2.4 Floating Point
+--------------------

+
+
+File: as.info, Node: Alpha Directives, Next: Alpha Opcodes, Prev: Alpha Floating Point, Up: Alpha-Dependent
+
+9.2.5 Alpha Assembler Directives
+--------------------------------
+
+`as' for the Alpha supports many additional directives for
+compatibility with the native assembler. This section describes them
+only briefly.
+
+ These are the additional directives in `as' for the Alpha:
+
+`.arch CPU'
+ Specifies the target processor. This is equivalent to the `-mCPU'
+ command-line option. *Note Options: Alpha Options, for a list of
+ values for CPU.
+
+`.ent FUNCTION[, N]'
+ Mark the beginning of FUNCTION. An optional number may follow for
+ compatibility with the OSF/1 assembler, but is ignored. When
+ generating `.mdebug' information, this will create a procedure
+ descriptor for the function. In ELF, it will mark the symbol as a
+ function a-la the generic `.type' directive.
+
+`.end FUNCTION'
+ Mark the end of FUNCTION. In ELF, it will set the size of the
+ symbol a-la the generic `.size' directive.
+
+`.mask MASK, OFFSET'
+ Indicate which of the integer registers are saved in the current
+ function's stack frame. MASK is interpreted a bit mask in which
+ bit N set indicates that register N is saved. The registers are
+ saved in a block located OFFSET bytes from the "canonical frame
+ address" (CFA) which is the value of the stack pointer on entry to
+ the function. The registers are saved sequentially, except that
+ the return address register (normally `$26') is saved first.
+
+ This and the other directives that describe the stack frame are
+ currently only used when generating `.mdebug' information. They
+ may in the future be used to generate DWARF2 `.debug_frame' unwind
+ information for hand written assembly.
+
+`.fmask MASK, OFFSET'
+ Indicate which of the floating-point registers are saved in the
+ current stack frame. The MASK and OFFSET parameters are
+ interpreted as with `.mask'.
+
+`.frame FRAMEREG, FRAMEOFFSET, RETREG[, ARGOFFSET]'
+ Describes the shape of the stack frame. The frame pointer in use
+ is FRAMEREG; normally this is either `$fp' or `$sp'. The frame
+ pointer is FRAMEOFFSET bytes below the CFA. The return address is
+ initially located in RETREG until it is saved as indicated in
+ `.mask'. For compatibility with OSF/1 an optional ARGOFFSET
+ parameter is accepted and ignored. It is believed to indicate the
+ offset from the CFA to the saved argument registers.
+
+`.prologue N'
+ Indicate that the stack frame is set up and all registers have been
+ spilled. The argument N indicates whether and how the function
+ uses the incoming "procedure vector" (the address of the called
+ function) in `$27'. 0 indicates that `$27' is not used; 1
+ indicates that the first two instructions of the function use `$27'
+ to perform a load of the GP register; 2 indicates that `$27' is
+ used in some non-standard way and so the linker cannot elide the
+ load of the procedure vector during relaxation.
+
+`.usepv FUNCTION, WHICH'
+ Used to indicate the use of the `$27' register, similar to
+ `.prologue', but without the other semantics of needing to be
+ inside an open `.ent'/`.end' block.
+
+ The WHICH argument should be either `no', indicating that `$27' is
+ not used, or `std', indicating that the first two instructions of
+ the function perform a GP load.
+
+ One might use this directive instead of `.prologue' if you are
+ also using dwarf2 CFI directives.
+
+`.gprel32 EXPRESSION'
+ Computes the difference between the address in EXPRESSION and the
+ GP for the current object file, and stores it in 4 bytes. In
+ addition to being smaller than a full 8 byte address, this also
+ does not require a dynamic relocation when used in a shared
+ library.
+
+`.t_floating EXPRESSION'
+ Stores EXPRESSION as an IEEE double precision value.
+
+`.s_floating EXPRESSION'
+ Stores EXPRESSION as an IEEE single precision value.
+
+`.f_floating EXPRESSION'
+ Stores EXPRESSION as a VAX F format value.
+
+`.g_floating EXPRESSION'
+ Stores EXPRESSION as a VAX G format value.
+
+`.d_floating EXPRESSION'
+ Stores EXPRESSION as a VAX D format value.
+
+`.set FEATURE'
+ Enables or disables various assembler features. Using the positive
+ name of the feature enables while using `noFEATURE' disables.
+
+ `at'
+ Indicates that macro expansions may clobber the "assembler
+ temporary" (`$at' or `$28') register. Some macros may not be
+ expanded without this and will generate an error message if
+ `noat' is in effect. When `at' is in effect, a warning will
+ be generated if `$at' is used by the programmer.
+
+ `macro'
+ Enables the expansion of macro instructions. Note that
+ variants of real instructions, such as `br label' vs `br
+ $31,label' are considered alternate forms and not macros.
+
+ `move'
+ `reorder'
+ `volatile'
+ These control whether and how the assembler may re-order
+ instructions. Accepted for compatibility with the OSF/1
+ assembler, but `as' does not do instruction scheduling, so
+ these features are ignored.
+
+ The following directives are recognized for compatibility with the
+OSF/1 assembler but are ignored.
+
+ .proc .aproc
+ .reguse .livereg
+ .option .aent
+ .ugen .eflag
+ .alias .noalias

+
+`.3byte EXPRESSIONS'
+ *TODO*
+
+`.4byte EXPRESSIONS'
+ *TODO*
+
+`.extAuxRegister NAME,ADDRESS,MODE'
+ The ARCtangent A4 has extensible auxiliary register space. The
+ auxiliary registers can be defined in the assembler source code by
+ using this directive. The first parameter is the NAME of the new
+ auxiallry register. The second parameter is the ADDRESS of the
+ register in the auxiliary register memory map for the variant of
+ the ARC. The third parameter specifies the MODE in which the
+ register can be operated is and it can be one of:
+
+ `r (readonly)'
+
+ `w (write only)'
+
+ `r|w (read or write)'
+
+ For example:
+
+ .extAuxRegister mulhi,0x12,w
+
+ This specifies an extension auxiliary register called _mulhi_
+ which is at address 0x12 in the memory space and which is only
+ writable.
+
+`.extCondCode SUFFIX,VALUE'
+ The condition codes on the ARCtangent A4 are extensible and can be
+ specified by means of this assembler directive. They are specified
+ by the suffix and the value for the condition code. They can be
+ used to specify extra condition codes with any values. For
+ example:
+
+ .extCondCode is_busy,0x14
+
+ add.is_busy r1,r2,r3
+ bis_busy _main
+
+`.extCoreRegister NAME,REGNUM,MODE,SHORTCUT'
+ Specifies an extension core register NAME for the application.
+ This allows a register NAME with a valid REGNUM between 0 and 60,
+ with the following as valid values for MODE
+
+ `_r_ (readonly)'
+
+ `_w_ (write only)'
+
+ `_r|w_ (read or write)'
+
+ The other parameter gives a description of the register having a
+ SHORTCUT in the pipeline. The valid values are:
+
+ `can_shortcut'
+
+ `cannot_shortcut'
+
+ For example:
+
+ .extCoreRegister mlo,57,r,can_shortcut
+
+ This defines an extension core register mlo with the value 57 which
+ can shortcut the pipeline.
+
+`.extInstruction NAME,OPCODE,SUBOPCODE,SUFFIXCLASS,SYNTAXCLASS'
+ The ARCtangent A4 allows the user to specify extension
+ instructions. The extension instructions are not macros. The
+ assembler creates encodings for use of these instructions
+ according to the specification by the user. The parameters are:
+
+ * NAME Name of the extension instruction
+
+ * OPCODE Opcode to be used. (Bits 27:31 in the encoding).
+ Valid values 0x10-0x1f or 0x03
+
+ * SUBOPCODE Subopcode to be used. Valid values are from
+ 0x09-0x3f. However the correct value also depends on
+ SYNTAXCLASS
+
+ * SUFFIXCLASS Determines the kinds of suffixes to be allowed.
+ Valid values are `SUFFIX_NONE', `SUFFIX_COND', `SUFFIX_FLAG'
+ which indicates the absence or presence of conditional
+ suffixes and flag setting by the extension instruction. It
+ is also possible to specify that an instruction sets the
+ flags and is conditional by using `SUFFIX_CODE' |
+ `SUFFIX_FLAG'.
+
+ * SYNTAXCLASS Determines the syntax class for the instruction.
+ It can have the following values:
+
+ ``SYNTAX_2OP':'
+ 2 Operand Instruction
+
+ ``SYNTAX_3OP':'
+ 3 Operand Instruction
+
+ In addition there could be modifiers for the syntax class as
+ described below:
+
+ Syntax Class Modifiers are:
+
+ - `OP1_MUST_BE_IMM': Modifies syntax class SYNTAX_3OP,
+ specifying that the first operand of a three-operand
+ instruction must be an immediate (i.e., the result is
+ discarded). OP1_MUST_BE_IMM is used by bitwise ORing it
+ with SYNTAX_3OP as given in the example below. This
+ could usually be used to set the flags using specific
+ instructions and not retain results.
+
+ - `OP1_IMM_IMPLIED': Modifies syntax class SYNTAX_20P, it
+ specifies that there is an implied immediate destination
+ operand which does not appear in the syntax. For
+ example, if the source code contains an instruction like:
+
+ inst r1,r2
+
+ it really means that the first argument is an implied
+ immediate (that is, the result is discarded). This is
+ the same as though the source code were: inst 0,r1,r2.
+ You use OP1_IMM_IMPLIED by bitwise ORing it with
+ SYNTAX_20P.
+
+
+ For example, defining 64-bit multiplier with immediate operands:
+
+ .extInstruction mp64,0x14,0x0,SUFFIX_COND | SUFFIX_FLAG ,
+ SYNTAX_3OP|OP1_MUST_BE_IMM
+
+ The above specifies an extension instruction called mp64 which has
+ 3 operands, sets the flags, can be used with a condition code, for
+ which the first operand is an immediate. (Equivalent to
+ discarding the result of the operation).
+
+ .extInstruction mul64,0x14,0x00,SUFFIX_COND, SYNTAX_2OP|OP1_IMM_IMPLIED
+
+ This describes a 2 operand instruction with an implicit first
+ immediate operand. The result of this operation would be
+ discarded.

+ `cortex-r7', `cortex-m4', `cortex-m3', `cortex-m1', `cortex-m0',
+ `cortex-m0plus', `ep9312' (ARM920 with Cirrus Maverick
+ coprocessor), `i80200' (Intel XScale processor) `iwmmxt' (Intel(r)
+ XScale processor with Wireless MMX(tm) technology coprocessor) and
+ `xscale'. The special name `all' may be used to allow the
+ assembler to accept instructions valid for any ARM processor.
+
+ In addition to the basic instruction set, the assembler can be
+ told to accept various extension mnemonics that extend the
+ processor using the co-processor instruction space. For example,
+ `-mcpu=arm920+maverick' is equivalent to specifying `-mcpu=ep9312'.
+
+ Multiple extensions may be specified, separated by a `+'. The
+ extensions should be specified in ascending alphabetical order.
+
+ Some extensions may be restricted to particular architectures;
+ this is documented in the list of extensions below.
+
+ Extension mnemonics may also be removed from those the assembler
+ accepts. This is done be prepending `no' to the option that adds
+ the extension. Extensions that are removed should be listed after
+ all extensions which have been added, again in ascending
+ alphabetical order. For example, `-mcpu=ep9312+nomaverick' is
+ equivalent to specifying `-mcpu=arm920'.
+
+ The following extensions are currently supported: `crypto'
+ (Cryptography Extensions for v8-A architecture, implies `fp+simd'),
+ `fp' (Floating Point Extensions for v8-A architecture), `idiv'
+ (Integer Divide Extensions for v7-A and v7-R architectures),
+ `iwmmxt', `iwmmxt2', `maverick', `mp' (Multiprocessing Extensions
+ for v7-A and v7-R architectures), `os' (Operating System for v6M
+ architecture), `sec' (Security Extensions for v6K and v7-A
+ architectures), `simd' (Advanced SIMD Extensions for v8-A
+ architecture, implies `fp'), `virt' (Virtualization Extensions for
+ v7-A architecture, implies `idiv'), and `xscale'.
+
+`-march=ARCHITECTURE[+EXTENSION...]'
+ This option specifies the target architecture. The assembler will
+ issue an error message if an attempt is made to assemble an
+ instruction which will not execute on the target architecture.
+ The following architecture names are recognized: `armv1', `armv2',
+ `armv2a', `armv2s', `armv3', `armv3m', `armv4', `armv4xm',
+ `armv4t', `armv4txm', `armv5', `armv5t', `armv5txm', `armv5te',
+ `armv5texp', `armv6', `armv6j', `armv6k', `armv6z', `armv6zk',
+ `armv6-m', `armv6s-m', `armv7', `armv7-a', `armv7ve', `armv7-r',
+ `armv7-m', `armv7e-m', `armv8-a', `iwmmxt' and `xscale'. If both
+ `-mcpu' and `-march' are specified, the assembler will use the
+ setting for `-mcpu'.
+
+ The architecture option can be extended with the same instruction
+ set extension options as the `-mcpu' option.
+
+`-mfpu=FLOATING-POINT-FORMAT'
+ This option specifies the floating point format to assemble for.
+ The assembler will issue an error message if an attempt is made to
+ assemble an instruction which will not execute on the target
+ floating point unit. The following format options are recognized:
+ `softfpa', `fpe', `fpe2', `fpe3', `fpa', `fpa10', `fpa11',
+ `arm7500fe', `softvfp', `softvfp+vfp', `vfp', `vfp10', `vfp10-r0',
+ `vfp9', `vfpxd', `vfpv2', `vfpv3', `vfpv3-fp16', `vfpv3-d16',
+ `vfpv3-d16-fp16', `vfpv3xd', `vfpv3xd-d16', `vfpv4', `vfpv4-d16',
+ `fpv4-sp-d16', `fp-armv8', `arm1020t', `arm1020e', `arm1136jf-s',
+ `maverick', `neon', `neon-vfpv4', `neon-fp-armv8', and
+ `crypto-neon-fp-armv8'.
+
+ In addition to determining which instructions are assembled, this
+ option also affects the way in which the `.double' assembler
+ directive behaves when assembling little-endian code.
+
+ The default is dependent on the processor selected. For
+ Architecture 5 or later, the default is to assembler for VFP
+ instructions; for earlier architectures the default is to assemble
+ for FPA instructions.
+
+`-mthumb'
+ This option specifies that the assembler should start assembling
+ Thumb instructions; that is, it should behave as though the file
+ starts with a `.code 16' directive.
+
+`-mthumb-interwork'
+ This option specifies that the output generated by the assembler
+ should be marked as supporting interworking.
+
+`-mimplicit-it=never'
+`-mimplicit-it=always'
+`-mimplicit-it=arm'
+`-mimplicit-it=thumb'
+ The `-mimplicit-it' option controls the behavior of the assembler
+ when conditional instructions are not enclosed in IT blocks.
+ There are four possible behaviors. If `never' is specified, such
+ constructs cause a warning in ARM code and an error in Thumb-2
+ code. If `always' is specified, such constructs are accepted in
+ both ARM and Thumb-2 code, where the IT instruction is added
+ implicitly. If `arm' is specified, such constructs are accepted
+ in ARM code and cause an error in Thumb-2 code. If `thumb' is
+ specified, such constructs cause a warning in ARM code and are
+ accepted in Thumb-2 code. If you omit this option, the behavior
+ is equivalent to `-mimplicit-it=arm'.
+
+`-mapcs-26'
+`-mapcs-32'
+ These options specify that the output generated by the assembler
+ should be marked as supporting the indicated version of the Arm
+ Procedure. Calling Standard.
+
+`-matpcs'
+ This option specifies that the output generated by the assembler
+ should be marked as supporting the Arm/Thumb Procedure Calling
+ Standard. If enabled this option will cause the assembler to
+ create an empty debugging section in the object file called
+ .arm.atpcs. Debuggers can use this to determine the ABI being
+ used by.
+
+`-mapcs-float'
+ This indicates the floating point variant of the APCS should be
+ used. In this variant floating point arguments are passed in FP
+ registers rather than integer registers.
+
+`-mapcs-reentrant'
+ This indicates that the reentrant variant of the APCS should be
+ used. This variant supports position independent code.
+
+`-mfloat-abi=ABI'
+ This option specifies that the output generated by the assembler
+ should be marked as using specified floating point ABI. The
+ following values are recognized: `soft', `softfp' and `hard'.
+
+`-meabi=VER'
+ This option specifies which EABI version the produced object files
+ should conform to. The following values are recognized: `gnu', `4'
+ and `5'.
+
+`-EB'
+ This option specifies that the output generated by the assembler
+ should be marked as being encoded for a big-endian processor.
+
+`-EL'
+ This option specifies that the output generated by the assembler
+ should be marked as being encoded for a little-endian processor.
+
+`-k'
+ This option specifies that the output of the assembler should be
+ marked as position-independent code (PIC).
+
+`--fix-v4bx'
+ Allow `BX' instructions in ARMv4 code. This is intended for use
+ with the linker option of the same name.
+
+`-mwarn-deprecated'
+`-mno-warn-deprecated'
+ Enable or disable warnings about using deprecated options or
+ features. The default is to warn.
+
+`-mccs'
+ Turns on CodeComposer Studio assembly syntax compatibility mode.

+9.4.2.1 Instruction Set Syntax
+..............................
+
+Two slightly different syntaxes are support for ARM and THUMB
+instructions. The default, `divided', uses the old style where ARM and
+THUMB instructions had their own, separate syntaxes. The new,
+`unified' syntax, which can be selected via the `.syntax' directive,
+and has the following main features:
+
+ * Immediate operands do not require a `#' prefix.
+
+ * The `IT' instruction may appear, and if it does it is validated
+ against subsequent conditional affixes. In ARM mode it does not
+ generate machine code, in THUMB mode it does.
+
+ * For ARM instructions the conditional affixes always appear at the
+ end of the instruction. For THUMB instructions conditional
+ affixes can be used, but only inside the scope of an `IT'
+ instruction.
+
+ * All of the instructions new to the V6T2 architecture (and later)
+ are available. (Only a few such instructions can be written in the
+ `divided' syntax).
+
+ * The `.N' and `.W' suffixes are recognized and honored.
+
+ * All instructions set the flags if and only if they have an `s'
+ affix.

+
+9.4.2.2 Special Characters
+..........................
+
+The presence of a `@' anywhere on a line indicates the start of a
+comment that extends to the end of that line.
+
+ If a `#' appears as the first character of a line then the whole
+line is treated as a comment, but in this case the line could also be a
+logical line number directive (*note Comments::) or a preprocessor
+control command (*note Preprocessing::).
+
+ The `;' character can be used instead of a newline to separate
+statements.
+
+ Either `#' or `$' can be used to indicate immediate operands.

+
+9.4.2.4 ARM relocation generation
+.................................
+
+Specific data relocations can be generated by putting the relocation
+name in parentheses after the symbol name. For example:
+
+ .word foo(TARGET1)
+
+ This will generate an `R_ARM_TARGET1' relocation against the symbol
+FOO. The following relocations are supported: `GOT', `GOTOFF',
+`TARGET1', `TARGET2', `SBREL', `TLSGD', `TLSLDM', `TLSLDO', `TLSDESC',
+`TLSCALL', `GOTTPOFF', `GOT_PREL' and `TPOFF'.
+
+ For compatibility with older toolchains the assembler also accepts
+`(PLT)' after branch targets. On legacy targets this will generate the
+deprecated `R_ARM_PLT32' relocation. On EABI targets it will encode
+either the `R_ARM_CALL' or `R_ARM_JUMP24' relocation, as appropriate.
+
+ Relocations for `MOVW' and `MOVT' instructions can be generated by
+prefixing the value with `#:lower16:' and `#:upper16' respectively.
+For example to load the 32-bit address of foo into r0:
+
+ MOVW r0, #:lower16:foo
+ MOVT r0, #:upper16:foo
+

+
+9.4.2.5 NEON Alignment Specifiers
+.................................
+
+Some NEON load/store instructions allow an optional address alignment
+qualifier. The ARM documentation specifies that this is indicated by
+`@ ALIGN'. However GAS already interprets the `@' character as a "line
+comment" start, so `: ALIGN' is used instead. For example:
+
+ vld1.8 {q0}, [r0, :128]

+
+9.4.4 ARM Machine Directives
+----------------------------
+
+`.2byte EXPRESSION [, EXPRESSION]*'
+`.4byte EXPRESSION [, EXPRESSION]*'
+`.8byte EXPRESSION [, EXPRESSION]*'
+ These directives write 2, 4 or 8 byte values to the output section.
+
+`.align EXPRESSION [, EXPRESSION]'
+ This is the generic .ALIGN directive. For the ARM however if the
+ first argument is zero (ie no alignment is needed) the assembler
+ will behave as if the argument had been 2 (ie pad to the next four
+ byte boundary). This is for compatibility with ARM's own
+ assembler.
+
+`.arch NAME'
+ Select the target architecture. Valid values for NAME are the
+ same as for the `-march' commandline option.
+
+ Specifying `.arch' clears any previously selected architecture
+ extensions.
+
+`.arch_extension NAME'
+ Add or remove an architecture extension to the target
+ architecture. Valid values for NAME are the same as those
+ accepted as architectural extensions by the `-mcpu' commandline
+ option.
+
+ `.arch_extension' may be used multiple times to add or remove
+ extensions incrementally to the architecture being compiled for.
+
+`.arm'
+ This performs the same action as .CODE 32.
+
+`.bss'
+ This directive switches to the `.bss' section.
+
+`.cantunwind'
+ Prevents unwinding through the current function. No personality
+ routine or exception table data is required or permitted.
+
+`.code `[16|32]''
+ This directive selects the instruction set being generated. The
+ value 16 selects Thumb, with the value 32 selecting ARM.
+
+`.cpu NAME'
+ Select the target processor. Valid values for NAME are the same as
+ for the `-mcpu' commandline option.
+
+ Specifying `.cpu' clears any previously selected architecture
+ extensions.
+
+`NAME .dn REGISTER NAME [.TYPE] [[INDEX]]'
+`NAME .qn REGISTER NAME [.TYPE] [[INDEX]]'
+ The `dn' and `qn' directives are used to create typed and/or
+ indexed register aliases for use in Advanced SIMD Extension (Neon)
+ instructions. The former should be used to create aliases of
+ double-precision registers, and the latter to create aliases of
+ quad-precision registers.
+
+ If these directives are used to create typed aliases, those
+ aliases can be used in Neon instructions instead of writing types
+ after the mnemonic or after each operand. For example:
+
+ x .dn d2.f32
+ y .dn d3.f32
+ z .dn d4.f32[1]
+ vmul x,y,z
+
+ This is equivalent to writing the following:
+
+ vmul.f32 d2,d3,d4[1]
+
+ Aliases created using `dn' or `qn' can be destroyed using `unreq'.
+
+`.eabi_attribute TAG, VALUE'
+ Set the EABI object attribute TAG to VALUE.
+
+ The TAG is either an attribute number, or one of the following:
+ `Tag_CPU_raw_name', `Tag_CPU_name', `Tag_CPU_arch',
+ `Tag_CPU_arch_profile', `Tag_ARM_ISA_use', `Tag_THUMB_ISA_use',
+ `Tag_FP_arch', `Tag_WMMX_arch', `Tag_Advanced_SIMD_arch',
+ `Tag_PCS_config', `Tag_ABI_PCS_R9_use', `Tag_ABI_PCS_RW_data',
+ `Tag_ABI_PCS_RO_data', `Tag_ABI_PCS_GOT_use',
+ `Tag_ABI_PCS_wchar_t', `Tag_ABI_FP_rounding',
+ `Tag_ABI_FP_denormal', `Tag_ABI_FP_exceptions',

+ `Tag_nodefaults', `Tag_also_compatible_with', `Tag_conformance',
+ `Tag_T2EE_use', `Tag_Virtualization_use'
+
+ The VALUE is either a `number', `"string"', or `number, "string"'
+ depending on the tag.
+
+ Note - the following legacy values are also accepted by TAG:
+ `Tag_VFP_arch', `Tag_ABI_align8_needed',
+ `Tag_ABI_align8_preserved', `Tag_VFP_HP_extension',
+
+`.even'
+ This directive aligns to an even-numbered address.
+
+`.extend EXPRESSION [, EXPRESSION]*'
+`.ldouble EXPRESSION [, EXPRESSION]*'
+ These directives write 12byte long double floating-point values to
+ the output section. These are not compatible with current ARM
+ processors or ABIs.
+
+`.fnend'
+ Marks the end of a function with an unwind table entry. The
+ unwind index table entry is created when this directive is
+ processed.
+
+ If no personality routine has been specified then standard
+ personality routine 0 or 1 will be used, depending on the number
+ of unwind opcodes required.
+
+`.fnstart'
+ Marks the start of a function with an unwind table entry.
+
+`.force_thumb'
+ This directive forces the selection of Thumb instructions, even if
+ the target processor does not support those instructions
+
+`.fpu NAME'
+ Select the floating-point unit to assemble for. Valid values for
+ NAME are the same as for the `-mfpu' commandline option.
+
+`.handlerdata'
+ Marks the end of the current function, and the start of the
+ exception table entry for that function. Anything between this
+ directive and the `.fnend' directive will be added to the
+ exception table entry.
+
+ Must be preceded by a `.personality' or `.personalityindex'
+ directive.
+
+`.inst OPCODE [ , ... ]'
+`.inst.n OPCODE [ , ... ]'
+`.inst.w OPCODE [ , ... ]'
+ Generates the instruction corresponding to the numerical value
+ OPCODE. `.inst.n' and `.inst.w' allow the Thumb instruction size
+ to be specified explicitly, overriding the normal encoding rules.
+
+`.ldouble EXPRESSION [, EXPRESSION]*'
+ See `.extend'.
+
+`.ltorg'
+ This directive causes the current contents of the literal pool to
+ be dumped into the current section (which is assumed to be the
+ .text section) at the current location (aligned to a word
+ boundary). `GAS' maintains a separate literal pool for each
+ section and each sub-section. The `.ltorg' directive will only
+ affect the literal pool of the current section and sub-section.
+ At the end of assembly all remaining, un-empty literal pools will
+ automatically be dumped.
+
+ Note - older versions of `GAS' would dump the current literal pool
+ any time a section change occurred. This is no longer done, since
+ it prevents accurate control of the placement of literal pools.
+
+`.movsp REG [, #OFFSET]'
+ Tell the unwinder that REG contains an offset from the current
+ stack pointer. If OFFSET is not specified then it is assumed to be
+ zero.
+
+`.object_arch NAME'
+ Override the architecture recorded in the EABI object attribute
+ section. Valid values for NAME are the same as for the `.arch'
+ directive. Typically this is useful when code uses runtime
+ detection of CPU features.
+
+`.packed EXPRESSION [, EXPRESSION]*'
+ This directive writes 12-byte packed floating-point values to the
+ output section. These are not compatible with current ARM
+ processors or ABIs.
+
+`.pad #COUNT'
+ Generate unwinder annotations for a stack adjustment of COUNT
+ bytes. A positive value indicates the function prologue allocated
+ stack space by decrementing the stack pointer.
+
+`.personality NAME'
+ Sets the personality routine for the current function to NAME.
+
+`.personalityindex INDEX'
+ Sets the personality routine for the current function to the EABI
+ standard routine number INDEX
+
+`.pool'
+ This is a synonym for .ltorg.
+
+`NAME .req REGISTER NAME'
+ This creates an alias for REGISTER NAME called NAME. For example:
+
+ foo .req r0
+
+`.save REGLIST'
+ Generate unwinder annotations to restore the registers in REGLIST.
+ The format of REGLIST is the same as the corresponding
+ store-multiple instruction.
+
+ _core registers_
+ .save {r4, r5, r6, lr}
+ stmfd sp!, {r4, r5, r6, lr}
+ _FPA registers_
+ .save f4, 2
+ sfmfd f4, 2, [sp]!
+ _VFP registers_
+ .save {d8, d9, d10}
+ fstmdx sp!, {d8, d9, d10}
+ _iWMMXt registers_
+ .save {wr10, wr11}
+ wstrd wr11, [sp, #-8]!
+ wstrd wr10, [sp, #-8]!
+ or
+ .save wr11
+ wstrd wr11, [sp, #-8]!
+ .save wr10
+ wstrd wr10, [sp, #-8]!
+
+`.setfp FPREG, SPREG [, #OFFSET]'
+ Make all unwinder annotations relative to a frame pointer.
+ Without this the unwinder will use offsets from the stack pointer.
+
+ The syntax of this directive is the same as the `add' or `mov'
+ instruction used to set the frame pointer. SPREG must be either
+ `sp' or mentioned in a previous `.movsp' directive.
+
+ .movsp ip
+ mov ip, sp
+ ...
+ .setfp fp, ip, #4
+ add fp, ip, #4
+
+`.secrel32 EXPRESSION [, EXPRESSION]*'
+ This directive emits relocations that evaluate to the
+ section-relative offset of each expression's symbol. This
+ directive is only supported for PE targets.
+
+`.syntax [`unified' | `divided']'
+ This directive sets the Instruction Set Syntax as described in the
+ *Note ARM-Instruction-Set:: section.
+
+`.thumb'
+ This performs the same action as .CODE 16.
+
+`.thumb_func'
+ This directive specifies that the following symbol is the name of a
+ Thumb encoded function. This information is necessary in order to
+ allow the assembler and linker to generate correct code for
+ interworking between Arm and Thumb instructions and should be used
+ even if interworking is not going to be performed. The presence
+ of this directive also implies `.thumb'
+
+ This directive is not neccessary when generating EABI objects. On
+ these targets the encoding is implicit when generating Thumb code.
+
+`.thumb_set'
+ This performs the equivalent of a `.set' directive in that it
+ creates a symbol which is an alias for another symbol (possibly
+ not yet defined). This directive also has the added property in
+ that it marks the aliased symbol as being a thumb function entry
+ point, in the same way that the `.thumb_func' directive does.
+
+`.tlsdescseq TLS-VARIABLE'
+ This directive is used to annotate parts of an inlined TLS
+ descriptor trampoline. Normally the trampoline is provided by the
+ linker, and this directive is not needed.
+
+`.unreq ALIAS-NAME'
+ This undefines a register alias which was previously defined using
+ the `req', `dn' or `qn' directives. For example:
+
+ foo .req r0
+ .unreq foo
+
+ An error occurs if the name is undefined. Note - this pseudo op
+ can be used to delete builtin in register name aliases (eg 'r0').
+ This should only be done if it is really necessary.
+
+`.unwind_raw OFFSET, BYTE1, ...'
+ Insert one of more arbitary unwind opcode bytes, which are known
+ to adjust the stack pointer by OFFSET bytes.
+
+ For example `.unwind_raw 4, 0xb1, 0x01' is equivalent to `.save
+ {r0}'
+
+`.vsave VFP-REGLIST'
+ Generate unwinder annotations to restore the VFP registers in
+ VFP-REGLIST using FLDMD. Also works for VFPv3 registers that are
+ to be restored using VLDM. The format of VFP-REGLIST is the same
+ as the corresponding store-multiple instruction.
+
+ _VFP registers_
+ .vsave {d8, d9, d10}
+ fstmdd sp!, {d8, d9, d10}
+ _VFPv3 registers_
+ .vsave {d15, d16, d17}
+ vstm sp!, {d15, d16, d17}
+
+ Since FLDMX and FSTMX are now deprecated, this directive should be
+ used in favour of `.save' for saving VFP registers for ARMv6 and
+ above.

+9.4.5 Opcodes
+-------------
+
+`as' implements all the standard ARM opcodes. It also implements
+several pseudo opcodes, including several synthetic load instructions.
+
+`NOP'
+ nop
+
+ This pseudo op will always evaluate to a legal ARM instruction
+ that does nothing. Currently it will evaluate to MOV r0, r0.
+
+`LDR'
+ ldr <register> , = <expression>
+
+ If expression evaluates to a numeric constant then a MOV or MVN
+ instruction will be used in place of the LDR instruction, if the
+ constant can be generated by either of these instructions.
+ Otherwise the constant will be placed into the nearest literal
+ pool (if it not already there) and a PC relative LDR instruction
+ will be generated.
+
+`ADR'
+ adr <register> <label>
+
+ This instruction will load the address of LABEL into the indicated
+ register. The instruction will evaluate to a PC relative ADD or
+ SUB instruction depending upon where the label is located. If the
+ label is out of range, or if it is not defined in the same file
+ (and section) as the ADR instruction, then an error will be
+ generated. This instruction will not make use of the literal pool.
+
+`ADRL'
+ adrl <register> <label>
+
+ This instruction will load the address of LABEL into the indicated
+ register. The instruction will evaluate to one or two PC relative
+ ADD or SUB instructions depending upon where the label is located.
+ If a second instruction is not needed a NOP instruction will be
+ generated in its place, so that this instruction is always 8 bytes
+ long.
+
+ If the label is out of range, or if it is not defined in the same
+ file (and section) as the ADRL instruction, then an error will be
+ generated. This instruction will not make use of the literal pool.

+
+9.4.6 Mapping Symbols
+---------------------
+
+The ARM ELF specification requires that special symbols be inserted
+into object files to mark certain features:
+
+`$a'
+ At the start of a region of code containing ARM instructions.
+
+`$t'
+ At the start of a region of code containing THUMB instructions.
+
+`$d'
+ At the start of a region of data.
+
+
+ The assembler will automatically insert these symbols for you - there
+is no need to code them yourself. Support for tagging symbols ($b, $f,
+$p and $m) which is also mentioned in the current ARM ELF specification
+is not implemented. This is because they have been dropped from the
+new EABI and so tools cannot rely upon their presence.
+
+
+File: as.info, Node: ARM Unwinding Tutorial, Prev: ARM Mapping Symbols, Up: ARM-Dependent
+
+9.4.7 Unwinding
+---------------
+
+The ABI for the ARM Architecture specifies a standard format for
+exception unwind information. This information is used when an
+exception is thrown to determine where control should be transferred.
+In particular, the unwind information is used to determine which
+function called the function that threw the exception, and which
+function called that one, and so forth. This information is also used
+to restore the values of callee-saved registers in the function
+catching the exception.
+
+ If you are writing functions in assembly code, and those functions
+call other functions that throw exceptions, you must use assembly
+pseudo ops to ensure that appropriate exception unwind information is
+generated. Otherwise, if one of the functions called by your assembly
+code throws an exception, the run-time library will be unable to unwind
+the stack through your assembly code and your program will not behave
+correctly.
+
+ To illustrate the use of these pseudo ops, we will examine the code
+that G++ generates for the following C++ input:
+
+
+void callee (int *);
+
+int
+caller ()
+{
+ int i;
+ callee (&i);
+ return i;
+}
+
+ This example does not show how to throw or catch an exception from
+assembly code. That is a much more complex operation and should always
+be done in a high-level language, such as C++, that directly supports
+exceptions.
+
+ The code generated by one particular version of G++ when compiling
+the example above is:
+
+
+_Z6callerv:
+ .fnstart
+.LFB2:
+ @ Function supports interworking.
+ @ args = 0, pretend = 0, frame = 8
+ @ frame_needed = 1, uses_anonymous_args = 0
+ stmfd sp!, {fp, lr}
+ .save {fp, lr}
+.LCFI0:
+ .setfp fp, sp, #4
+ add fp, sp, #4
+.LCFI1:
+ .pad #8
+ sub sp, sp, #8
+.LCFI2:
+ sub r3, fp, #8
+ mov r0, r3
+ bl _Z6calleePi
+ ldr r3, [fp, #-8]
+ mov r0, r3
+ sub sp, fp, #4
+ ldmfd sp!, {fp, lr}
+ bx lr
+.LFE2:
+ .fnend
+
+ Of course, the sequence of instructions varies based on the options
+you pass to GCC and on the version of GCC in use. The exact
+instructions are not important since we are focusing on the pseudo ops
+that are used to generate unwind information.
+
+ An important assumption made by the unwinder is that the stack frame
+does not change during the body of the function. In particular, since
+we assume that the assembly code does not itself throw an exception,
+the only point where an exception can be thrown is from a call, such as
+the `bl' instruction above. At each call site, the same saved
+registers (including `lr', which indicates the return address) must be
+located in the same locations relative to the frame pointer.
+
+ The `.fnstart' (*note .fnstart pseudo op: arm_fnstart.) pseudo op
+appears immediately before the first instruction of the function while
+the `.fnend' (*note .fnend pseudo op: arm_fnend.) pseudo op appears
+immediately after the last instruction of the function. These pseudo
+ops specify the range of the function.
+
+ Only the order of the other pseudos ops (e.g., `.setfp' or `.pad')
+matters; their exact locations are irrelevant. In the example above,
+the compiler emits the pseudo ops with particular instructions. That
+makes it easier to understand the code, but it is not required for
+correctness. It would work just as well to emit all of the pseudo ops
+other than `.fnend' in the same order, but immediately after `.fnstart'.
+
+ The `.save' (*note .save pseudo op: arm_save.) pseudo op indicates
+registers that have been saved to the stack so that they can be
+restored before the function returns. The argument to the `.save'
+pseudo op is a list of registers to save. If a register is
+"callee-saved" (as specified by the ABI) and is modified by the
+function you are writing, then your code must save the value before it
+is modified and restore the original value before the function returns.
+If an exception is thrown, the run-time library restores the values of
+these registers from their locations on the stack before returning
+control to the exception handler. (Of course, if an exception is not
+thrown, the function that contains the `.save' pseudo op restores these
+registers in the function epilogue, as is done with the `ldmfd'
+instruction above.)
+
+ You do not have to save callee-saved registers at the very beginning
+of the function and you do not need to use the `.save' pseudo op
+immediately following the point at which the registers are saved.
+However, if you modify a callee-saved register, you must save it on the
+stack before modifying it and before calling any functions which might
+throw an exception. And, you must use the `.save' pseudo op to
+indicate that you have done so.
+
+ The `.pad' (*note .pad: arm_pad.) pseudo op indicates a modification
+of the stack pointer that does not save any registers. The argument is
+the number of bytes (in decimal) that are subtracted from the stack
+pointer. (On ARM CPUs, the stack grows downwards, so subtracting from
+the stack pointer increases the size of the stack.)
+
+ The `.setfp' (*note .setfp pseudo op: arm_setfp.) pseudo op
+indicates the register that contains the frame pointer. The first
+argument is the register that is set, which is typically `fp'. The
+second argument indicates the register from which the frame pointer
+takes its value. The third argument, if present, is the value (in
+decimal) added to the register specified by the second argument to
+compute the value of the frame pointer. You should not modify the
+frame pointer in the body of the function.
+
+ If you do not use a frame pointer, then you should not use the
+`.setfp' pseudo op. If you do not use a frame pointer, then you should
+avoid modifying the stack pointer outside of the function prologue.
+Otherwise, the run-time library will be unable to find saved registers
+when it is unwinding the stack.
+
+ The pseudo ops described above are sufficient for writing assembly
+code that calls functions which may throw exceptions. If you need to
+know more about the object-file format used to represent unwind
+information, you may consult the `Exception Handling ABI for the ARM
+Architecture' available from `http://infocenter.arm.com'.

+comment that extends to the end of that line.
+
+ If a `#' appears as the first character of a line, the whole line is

+indirect address register pointers for Data Space addressing. One of
+the these address pointers can also be used as an address pointer for
+look up tables in Flash program memory. These added function registers
+are the 16-bit `X', `Y' and `Z' - registers.

+
+9.5.2.3 Relocatable Expression Modifiers
+........................................
+
+The assembler supports several modifiers when using relocatable
+addresses in AVR instruction operands. The general syntax is the
+following:
+
+ modifier(relocatable-expression)
+
+`lo8'
+ This modifier allows you to use bits 0 through 7 of an address
+ expression as 8 bit relocatable expression.
+
+`hi8'
+ This modifier allows you to use bits 7 through 15 of an address
+ expression as 8 bit relocatable expression. This is useful with,
+ for example, the AVR `ldi' instruction and `lo8' modifier.
+
+ For example
+
+ ldi r26, lo8(sym+10)
+ ldi r27, hi8(sym+10)
+
+`hh8'
+ This modifier allows you to use bits 16 through 23 of an address
+ expression as 8 bit relocatable expression. Also, can be useful
+ for loading 32 bit constants.
+
+`hlo8'
+ Synonym of `hh8'.
+
+`hhi8'
+ This modifier allows you to use bits 24 through 31 of an
+ expression as 8 bit expression. This is useful with, for example,
+ the AVR `ldi' instruction and `lo8', `hi8', `hlo8', `hhi8',
+ modifier.
+
+ For example
+
+ ldi r26, lo8(285774925)
+ ldi r27, hi8(285774925)
+ ldi r28, hlo8(285774925)
+ ldi r29, hhi8(285774925)
+ ; r29,r28,r27,r26 = 285774925
+
+`pm_lo8'
+ This modifier allows you to use bits 0 through 7 of an address
+ expression as 8 bit relocatable expression. This modifier useful
+ for addressing data or code from Flash/Program memory. The using
+ of `pm_lo8' similar to `lo8'.
+
+`pm_hi8'
+ This modifier allows you to use bits 8 through 15 of an address
+ expression as 8 bit relocatable expression. This modifier useful
+ for addressing data or code from Flash/Program memory.
+
+`pm_hh8'
+ This modifier allows you to use bits 15 through 23 of an address
+ expression as 8 bit relocatable expression. This modifier useful
+ for addressing data or code from Flash/Program memory.

+
+File: as.info, Node: Blackfin Options, Next: Blackfin Syntax, Up: Blackfin-Dependent
+
+9.6.1 Options
+-------------
+
+`-mcpu=PROCESSOR[-SIREVISION]'
+ This option specifies the target processor. The optional
+ SIREVISION is not used in assembler. It's here such that GCC can
+ easily pass down its `-mcpu=' option. The assembler will issue an
+ error message if an attempt is made to assemble an instruction
+ which will not execute on the target processor. The following
+ processor names are recognized: `bf504', `bf506', `bf512', `bf514',
+ `bf516', `bf518', `bf522', `bf523', `bf524', `bf525', `bf526',
+ `bf527', `bf531', `bf532', `bf533', `bf534', `bf535' (not
+ implemented yet), `bf536', `bf537', `bf538', `bf539', `bf542',
+ `bf542m', `bf544', `bf544m', `bf547', `bf547m', `bf548', `bf548m',
+ `bf549', `bf549m', `bf561', and `bf592'.
+
+`-mfdpic'
+ Assemble for the FDPIC ABI.
+
+`-mno-fdpic'
+`-mnopic'
+ Disable -mfdpic.
+
+
+File: as.info, Node: Blackfin Syntax, Next: Blackfin Directives, Prev: Blackfin Options, Up: Blackfin-Dependent
+
+9.6.2 Syntax
+------------
+
+`Special Characters'
+ Assembler input is free format and may appear anywhere on the line.
+ One instruction may extend across multiple lines or more than one
+ instruction may appear on the same line. White space (space, tab,
+ comments or newline) may appear anywhere between tokens. A token
+ must not have embedded spaces. Tokens include numbers, register
+ names, keywords, user identifiers, and also some multicharacter
+ special symbols like "+=", "/*" or "||".
+
+ Comments are introduced by the `#' character and extend to the end
+ of the current line. If the `#' appears as the first character of
+ a line, the whole line is treated as a comment, but in this case
+ the line can also be a logical line number directive (*note
+ Comments::) or a preprocessor control command (*note
+ Preprocessing::).
+
+`Instruction Delimiting'
+ A semicolon must terminate every instruction. Sometimes a complete
+ instruction will consist of more than one operation. There are two
+ cases where this occurs. The first is when two general operations
+ are combined. Normally a comma separates the different parts, as
+ in
+
+ a0= r3.h * r2.l, a1 = r3.l * r2.h ;
+
+ The second case occurs when a general instruction is combined with
+ one or two memory references for joint issue. The latter portions
+ are set off by a "||" token.
+
+ a0 = r3.h * r2.l || r1 = [p3++] || r4 = [i2++];
+
+ Multiple instructions can occur on the same line. Each must be
+ terminated by a semicolon character.
+
+`Register Names'
+ The assembler treats register names and instruction keywords in a
+ case insensitive manner. User identifiers are case sensitive.
+ Thus, R3.l, R3.L, r3.l and r3.L are all equivalent input to the
+ assembler.
+
+ Register names are reserved and may not be used as program
+ identifiers.
+
+ Some operations (such as "Move Register") require a register pair.
+ Register pairs are always data registers and are denoted using a
+ colon, eg., R3:2. The larger number must be written firsts. Note
+ that the hardware only supports odd-even pairs, eg., R7:6, R5:4,
+ R3:2, and R1:0.
+
+ Some instructions (such as -SP (Push Multiple)) require a group of
+ adjacent registers. Adjacent registers are denoted in the syntax
+ by the range enclosed in parentheses and separated by a colon,
+ eg., (R7:3). Again, the larger number appears first.
+
+ Portions of a particular register may be individually specified.
+ This is written with a dot (".") following the register name and
+ then a letter denoting the desired portion. For 32-bit registers,
+ ".H" denotes the most significant ("High") portion. ".L" denotes
+ the least-significant portion. The subdivisions of the 40-bit
+ registers are described later.
+
+`Accumulators'
+ The set of 40-bit registers A1 and A0 that normally contain data
+ that is being manipulated. Each accumulator can be accessed in
+ four ways.
+
+ `one 40-bit register'
+ The register will be referred to as A1 or A0.
+
+ `one 32-bit register'
+ The registers are designated as A1.W or A0.W.
+
+ `two 16-bit registers'
+ The registers are designated as A1.H, A1.L, A0.H or A0.L.
+
+ `one 8-bit register'
+ The registers are designated as A1.X or A0.X for the bits that
+ extend beyond bit 31.
+
+`Data Registers'
+ The set of 32-bit registers (R0, R1, R2, R3, R4, R5, R6 and R7)
+ that normally contain data for manipulation. These are
+ abbreviated as D-register or Dreg. Data registers can be accessed
+ as 32-bit registers or as two independent 16-bit registers. The
+ least significant 16 bits of each register is called the "low"
+ half and is designated with ".L" following the register name. The
+ most significant 16 bits are called the "high" half and is
+ designated with ".H" following the name.
+
+ R7.L, r2.h, r4.L, R0.H
+
+`Pointer Registers'
+ The set of 32-bit registers (P0, P1, P2, P3, P4, P5, SP and FP)
+ that normally contain byte addresses of data structures. These are
+ abbreviated as P-register or Preg.
+
+ p2, p5, fp, sp
+
+`Stack Pointer SP'
+ The stack pointer contains the 32-bit address of the last occupied
+ byte location in the stack. The stack grows by decrementing the
+ stack pointer.
+
+`Frame Pointer FP'
+ The frame pointer contains the 32-bit address of the previous frame
+ pointer in the stack. It is located at the top of a frame.
+
+`Loop Top'
+ LT0 and LT1. These registers contain the 32-bit address of the
+ top of a zero overhead loop.
+
+`Loop Count'
+ LC0 and LC1. These registers contain the 32-bit counter of the
+ zero overhead loop executions.
+
+`Loop Bottom'
+ LB0 and LB1. These registers contain the 32-bit address of the
+ bottom of a zero overhead loop.
+
+`Index Registers'
+ The set of 32-bit registers (I0, I1, I2, I3) that normally contain
+ byte addresses of data structures. Abbreviated I-register or Ireg.
+
+`Modify Registers'
+ The set of 32-bit registers (M0, M1, M2, M3) that normally contain
+ offset values that are added and subtracted to one of the index
+ registers. Abbreviated as Mreg.
+
+`Length Registers'
+ The set of 32-bit registers (L0, L1, L2, L3) that normally contain
+ the length in bytes of the circular buffer. Abbreviated as Lreg.
+ Clear the Lreg to disable circular addressing for the
+ corresponding Ireg.
+
+`Base Registers'
+ The set of 32-bit registers (B0, B1, B2, B3) that normally contain
+ the base address in bytes of the circular buffer. Abbreviated as
+ Breg.
+
+`Floating Point'
+ The Blackfin family has no hardware floating point but the .float
+ directive generates ieee floating point numbers for use with
+ software floating point libraries.
+
+`Blackfin Opcodes'
+ For detailed information on the Blackfin machine instruction set,
+ see the Blackfin(r) Processor Instruction Set Reference.

+
+9.7.1 CR16 Operand Qualifiers
+-----------------------------
+
+The National Semiconductor CR16 target of `as' has a few machine
+dependent operand qualifiers.
+
+ Operand expression type qualifier is an optional field in the
+instruction operand, to determines the type of the expression field of
+an operand. The `@' is required. CR16 architecture uses one of the
+following expression qualifiers:
+
+`s'
+ - `Specifies expression operand type as small'
+
+`m'
+ - `Specifies expression operand type as medium'
+
+`l'
+ - `Specifies expression operand type as large'
+
+`c'
+ - `Specifies the CR16 Assembler generates a relocation entry for
+ the operand, where pc has implied bit, the expression is adjusted
+ accordingly. The linker uses the relocation entry to update the
+ operand address at link time.'
+
+`got/GOT'
+ - `Specifies the CR16 Assembler generates a relocation entry for
+ the operand, offset from Global Offset Table. The linker uses this
+ relocation entry to update the operand address at link time'
+
+`cgot/cGOT'
+ - `Specifies the CompactRISC Assembler generates a relocation
+ entry for the operand, where pc has implied bit, the expression is
+ adjusted accordingly. The linker uses the relocation entry to
+ update the operand address at link time.'
+
+ CR16 target operand qualifiers and its size (in bits):
+
+`Immediate Operand: s'
+ 4 bits.
+
+`Immediate Operand: m'
+ 16 bits, for movb and movw instructions.
+
+`Immediate Operand: m'
+ 20 bits, movd instructions.
+
+`Immediate Operand: l'
+ 32 bits.
+
+`Absolute Operand: s'
+ Illegal specifier for this operand.
+
+`Absolute Operand: m'
+ 20 bits, movd instructions.
+
+`Displacement Operand: s'
+ 8 bits.
+
+`Displacement Operand: m'
+ 16 bits.
+
+`Displacement Operand: l'
+ 24 bits.
+
+
+ For example:
+ 1 `movw $_myfun@c,r1'
+
+ This loads the address of _myfun, shifted right by 1, into r1.
+
+ 2 `movd $_myfun@c,(r2,r1)'
+
+ This loads the address of _myfun, shifted right by 1, into register-pair r2-r1.
+
+ 3 `_myfun_ptr:'
+ `.long _myfun@c'
+ `loadd _myfun_ptr, (r1,r0)'
+ `jal (r1,r0)'
+
+ This .long directive, the address of _myfunc, shifted right by 1 at link time.
+
+ 4 `loadd _data1@GOT(r12), (r1,r0)'
+
+ This loads the address of _data1, into global offset table (ie GOT) and its offset value from GOT loads into register-pair r2-r1.
+
+ 5 `loadd _myfunc@cGOT(r12), (r1,r0)'
+
+ This loads the address of _myfun, shifted right by 1, into global offset table (ie GOT) and its offset value from GOT loads into register-pair r1-r0.

+
+The presence of a `#' on a line indicates the start of a comment that
+extends to the end of the current line. If the `#' appears as the
+first character of a line, the whole line is treated as a comment, but
+in this case the line can also be a logical line number directive
+(*note Comments::) or a preprocessor control command (*note
+Preprocessing::).
+
+ The `;' character can be used to separate statements on the same

+
+9.8.1 Command-line Options
+--------------------------
+
+The CRIS version of `as' has these machine-dependent command-line
+options.
+
+ The format of the generated object files can be either ELF or a.out,
+specified by the command-line options `--emulation=crisaout' and
+`--emulation=criself'. The default is ELF (criself), unless `as' has
+been configured specifically for a.out by using the configuration name
+`cris-axis-aout'.
+
+ There are two different link-incompatible ELF object file variants
+for CRIS, for use in environments where symbols are expected to be
+prefixed by a leading `_' character and for environments without such a
+symbol prefix. The variant used for GNU/Linux port has no symbol
+prefix. Which variant to produce is specified by either of the options
+`--underscore' and `--no-underscore'. The default is `--underscore'.
+Since symbols in CRIS a.out objects are expected to have a `_' prefix,
+specifying `--no-underscore' when generating a.out objects is an error.
+Besides the object format difference, the effect of this option is to
+parse register names differently (*note crisnous::). The
+`--no-underscore' option makes a `$' register prefix mandatory.
+
+ The option `--pic' must be passed to `as' in order to recognize the
+symbol syntax used for ELF (SVR4 PIC) position-independent-code (*note
+crispic::). This will also affect expansion of instructions. The
+expansion with `--pic' will use PC-relative rather than (slightly
+faster) absolute addresses in those expansions. This option is only
+valid when generating ELF format object files.
+
+ The option `--march=ARCHITECTURE' specifies the recognized
+instruction set and recognized register names. It also controls the
+architecture type of the object file. Valid values for ARCHITECTURE
+are:
+`v0_v10'
+ All instructions and register names for any architecture variant
+ in the set v0...v10 are recognized. This is the default if the
+ target is configured as cris-*.
+
+`v10'
+ Only instructions and register names for CRIS v10 (as found in
+ ETRAX 100 LX) are recognized. This is the default if the target
+ is configured as crisv10-*.
+
+`v32'
+ Only instructions and register names for CRIS v32 (code name
+ Guinness) are recognized. This is the default if the target is
+ configured as crisv32-*. This value implies `--no-mul-bug-abort'.
+ (A subsequent `--mul-bug-abort' will turn it back on.)
+
+`common_v10_v32'
+ Only instructions with register names and addressing modes with
+ opcodes common to the v10 and v32 are recognized.
+
+ When `-N' is specified, `as' will emit a warning when a 16-bit
+branch instruction is expanded into a 32-bit multiple-instruction
+construct (*note CRIS-Expand::).
+
+ Some versions of the CRIS v10, for example in the Etrax 100 LX,
+contain a bug that causes destabilizing memory accesses when a multiply
+instruction is executed with certain values in the first operand just
+before a cache-miss. When the `--mul-bug-abort' command line option is
+active (the default value), `as' will refuse to assemble a file
+containing a multiply instruction at a dangerous offset, one that could
+be the last on a cache-line, or is in a section with insufficient
+alignment. This placement checking does not catch any case where the
+multiply instruction is dangerously placed because it is located in a
+delay-slot. The `--mul-bug-abort' command line option turns off the
+checking.

+File: as.info, Node: CRIS-Expand, Next: CRIS-Symbols, Prev: CRIS-Opts, Up: CRIS-Dependent
+
+9.8.2 Instruction expansion
+---------------------------
+
+`as' will silently choose an instruction that fits the operand size for
+`[register+constant]' operands. For example, the offset `127' in
+`move.d [r3+127],r4' fits in an instruction using a signed-byte offset.
+Similarly, `move.d [r2+32767],r1' will generate an instruction using a
+16-bit offset. For symbolic expressions and constants that do not fit
+in 16 bits including the sign bit, a 32-bit offset is generated.
+
+ For branches, `as' will expand from a 16-bit branch instruction into
+a sequence of instructions that can reach a full 32-bit address. Since
+this does not correspond to a single instruction, such expansions can
+optionally be warned about. *Note CRIS-Opts::.
+
+ If the operand is found to fit the range, a `lapc' mnemonic will
+translate to a `lapcq' instruction. Use `lapc.d' to force the 32-bit
+`lapc' instruction.
+
+ Similarly, the `addo' mnemonic will translate to the shortest
+fitting instruction of `addoq', `addo.w' and `addo.d', when used with a
+operand that is a constant known at assembly time.

+Some symbols are defined by the assembler. They're intended to be used
+in conditional assembly, for example:
+ .if ..asm.arch.cris.v32
+ CODE FOR CRIS V32
+ .elseif ..asm.arch.cris.common_v10_v32
+ CODE COMMON TO CRIS V32 AND CRIS V10
+ .elseif ..asm.arch.cris.v10 | ..asm.arch.cris.any_v0_v10
+ CODE FOR V10
+ .else
+ .error "Code needs to be added here."
+ .endif
+
+ These symbols are defined in the assembler, reflecting command-line
+options, either when specified or the default. They are always
+defined, to 0 or 1.
+`..asm.arch.cris.any_v0_v10'
+ This symbol is non-zero when `--march=v0_v10' is specified or the
+ default.
+
+`..asm.arch.cris.common_v10_v32'
+ Set according to the option `--march=common_v10_v32'.
+
+`..asm.arch.cris.v10'
+ Reflects the option `--march=v10'.
+
+`..asm.arch.cris.v32'
+ Corresponds to `--march=v10'.
+
+ Speaking of symbols, when a symbol is used in code, it can have a
+suffix modifying its value for use in position-independent code. *Note
+CRIS-Pic::.

+
+9.8.4.1 Special Characters
+..........................
+
+The character `#' is a line comment character. It starts a comment if
+and only if it is placed at the beginning of a line.
+
+ A `;' character starts a comment anywhere on the line, causing all
+characters up to the end of the line to be ignored.
+
+ A `@' character is handled as a line separator equivalent to a
+logical new-line character (except in a comment), so separate
+instructions can be specified on a single line.
+
+
+File: as.info, Node: CRIS-Pic, Next: CRIS-Regs, Prev: CRIS-Chars, Up: CRIS-Syntax
+
+9.8.4.2 Symbols in position-independent code
+............................................
+
+When generating position-independent code (SVR4 PIC) for use in
+cris-axis-linux-gnu or crisv32-axis-linux-gnu shared libraries, symbol
+suffixes are used to specify what kind of run-time symbol lookup will
+be used, expressed in the object as different _relocation types_.
+Usually, all absolute symbol values must be located in a table, the
+_global offset table_, leaving the code position-independent;
+independent of values of global symbols and independent of the address
+of the code. The suffix modifies the value of the symbol, into for
+example an index into the global offset table where the real symbol
+value is entered, or a PC-relative value, or a value relative to the
+start of the global offset table. All symbol suffixes start with the
+character `:' (omitted in the list below). Every symbol use in code or
+a read-only section must therefore have a PIC suffix to enable a useful
+shared library to be created. Usually, these constructs must not be
+used with an additive constant offset as is usually allowed, i.e. no 4
+as in `symbol + 4' is allowed. This restriction is checked at
+link-time, not at assembly-time.
+
+`GOT'
+ Attaching this suffix to a symbol in an instruction causes the
+ symbol to be entered into the global offset table. The value is a
+ 32-bit index for that symbol into the global offset table. The
+ name of the corresponding relocation is `R_CRIS_32_GOT'. Example:
+ `move.d [$r0+extsym:GOT],$r9'
+
+`GOT16'
+ Same as for `GOT', but the value is a 16-bit index into the global
+ offset table. The corresponding relocation is `R_CRIS_16_GOT'.
+ Example: `move.d [$r0+asymbol:GOT16],$r10'
+
+`PLT'
+ This suffix is used for function symbols. It causes a _procedure
+ linkage table_, an array of code stubs, to be created at the time
+ the shared object is created or linked against, together with a
+ global offset table entry. The value is a pc-relative offset to
+ the corresponding stub code in the procedure linkage table. This
+ arrangement causes the run-time symbol resolver to be called to
+ look up and set the value of the symbol the first time the
+ function is called (at latest; depending environment variables).
+ It is only safe to leave the symbol unresolved this way if all
+ references are function calls. The name of the relocation is
+ `R_CRIS_32_PLT_PCREL'. Example: `add.d fnname:PLT,$pc'
+
+`PLTG'
+ Like PLT, but the value is relative to the beginning of the global
+ offset table. The relocation is `R_CRIS_32_PLT_GOTREL'. Example:
+ `move.d fnname:PLTG,$r3'
+
+`GOTPLT'
+ Similar to `PLT', but the value of the symbol is a 32-bit index
+ into the global offset table. This is somewhat of a mix between
+ the effect of the `GOT' and the `PLT' suffix; the difference to
+ `GOT' is that there will be a procedure linkage table entry
+ created, and that the symbol is assumed to be a function entry and
+ will be resolved by the run-time resolver as with `PLT'. The
+ relocation is `R_CRIS_32_GOTPLT'. Example: `jsr
+ [$r0+fnname:GOTPLT]'
+
+`GOTPLT16'
+ A variant of `GOTPLT' giving a 16-bit value. Its relocation name
+ is `R_CRIS_16_GOTPLT'. Example: `jsr [$r0+fnname:GOTPLT16]'
+
+`GOTOFF'
+ This suffix must only be attached to a local symbol, but may be
+ used in an expression adding an offset. The value is the address
+ of the symbol relative to the start of the global offset table.
+ The relocation name is `R_CRIS_32_GOTREL'. Example: `move.d
+ [$r0+localsym:GOTOFF],r3'

+
+9.8.4.3 Register names
+......................
+
+A `$' character may always prefix a general or special register name in
+an instruction operand but is mandatory when the option
+`--no-underscore' is specified or when the `.syntax register_prefix'
+directive is in effect (*note crisnous::). Register names are
+case-insensitive.
+
+
+File: as.info, Node: CRIS-Pseudos, Prev: CRIS-Regs, Up: CRIS-Syntax
+
+9.8.4.4 Assembler Directives
+............................
+
+There are a few CRIS-specific pseudo-directives in addition to the
+generic ones. *Note Pseudo Ops::. Constants emitted by
+pseudo-directives are in little-endian order for CRIS. There is no
+support for floating-point-specific directives for CRIS.
+
+`.dword EXPRESSIONS'
+ The `.dword' directive is a synonym for `.int', expecting zero or
+ more EXPRESSIONS, separated by commas. For each expression, a
+ 32-bit little-endian constant is emitted.
+
+`.syntax ARGUMENT'
+ The `.syntax' directive takes as ARGUMENT one of the following
+ case-sensitive choices.
+
+ `no_register_prefix'
+ The `.syntax no_register_prefix' directive makes a `$'
+ character prefix on all registers optional. It overrides a
+ previous setting, including the corresponding effect of the
+ option `--no-underscore'. If this directive is used when
+ ordinary symbols do not have a `_' character prefix, care
+ must be taken to avoid ambiguities whether an operand is a
+ register or a symbol; using symbols with names the same as
+ general or special registers then invoke undefined behavior.
+
+ `register_prefix'
+ This directive makes a `$' character prefix on all registers
+ mandatory. It overrides a previous setting, including the
+ corresponding effect of the option `--underscore'.
+
+ `leading_underscore'
+ This is an assertion directive, emitting an error if the
+ `--no-underscore' option is in effect.
+
+ `no_leading_underscore'
+ This is the opposite of the `.syntax leading_underscore'
+ directive and emits an error if the option `--underscore' is
+ in effect.
+
+`.arch ARGUMENT'
+ This is an assertion directive, giving an error if the specified
+ ARGUMENT is not the same as the specified or default value for the
+ `--march=ARCHITECTURE' option (*note march-option::).

+9.9.1 D10V Options
+------------------
+
+The Mitsubishi D10V version of `as' has a few machine dependent options.
+
+`-O'
+ The D10V can often execute two sub-instructions in parallel. When
+ this option is used, `as' will attempt to optimize its output by
+ detecting when instructions can be executed in parallel.
+
+`--nowarnswap'
+ To optimize execution performance, `as' will sometimes swap the
+ order of instructions. Normally this generates a warning. When
+ this option is used, no warning will be generated when
+ instructions are swapped.
+
+`--gstabs-packing'
+`--no-gstabs-packing'
+ `as' packs adjacent short instructions into a single packed
+ instruction. `--no-gstabs-packing' turns instruction packing off if
+ `--gstabs' is specified as well; `--gstabs-packing' (the default)
+ turns instruction packing on even when `--gstabs' is specified.

+architecture manual. The differences are detailed below.

+
+9.9.2.1 Size Modifiers
+......................
+
+The D10V version of `as' uses the instruction names in the D10V
+Architecture Manual. However, the names in the manual are sometimes
+ambiguous. There are instruction names that can assemble to a short or
+long form opcode. How does the assembler pick the correct form? `as'
+will always pick the smallest form if it can. When dealing with a
+symbol that is not defined yet when a line is being assembled, it will
+always use the long form. If you need to force the assembler to use
+either the short or long form of the instruction, you can append either
+`.s' (short) or `.l' (long) to it. For example, if you are writing an
+assembly program and you want to do a branch to a symbol that is
+defined later in your program, you can write `bra.s foo'. Objdump
+and GDB will always append `.s' or `.l' to instructions which have both
+short and long forms.
+
+
+File: as.info, Node: D10V-Subs, Next: D10V-Chars, Prev: D10V-Size, Up: D10V-Syntax
+
+9.9.2.2 Sub-Instructions
+........................
+
+The D10V assembler takes as input a series of instructions, either
+one-per-line, or in the special two-per-line format described in the
+next section. Some of these instructions will be short-form or
+sub-instructions. These sub-instructions can be packed into a single
+instruction. The assembler will do this automatically. It will also
+detect when it should not pack instructions. For example, when a label
+is defined, the next instruction will never be packaged with the
+previous one. Whenever a branch and link instruction is called, it
+will not be packaged with the next instruction so the return address
+will be valid. Nops are automatically inserted when necessary.
+
+ If you do not want the assembler automatically making these
+decisions, you can control the packaging and execution type (parallel
+or sequential) with the special execution symbols described in the next
+section.
+
+
+File: as.info, Node: D10V-Chars, Next: D10V-Regs, Prev: D10V-Subs, Up: D10V-Syntax
+
+9.9.2.3 Special Characters
+..........................
+
+A semicolon (`;') can be used anywhere on a line to start a comment
+that extends to the end of the line.
+
+ If a `#' appears as the first character of a line, the whole line is
+treated as a comment, but in this case the line could also be a logical
+line number directive (*note Comments::) or a preprocessor control
+command (*note Preprocessing::).
+
+ Sub-instructions may be executed in order, in reverse-order, or in
+parallel. Instructions listed in the standard one-per-line format will
+be executed sequentially. To specify the executing order, use the
+following symbols:
+`->'
+ Sequential with instruction on the left first.
+
+`<-'
+ Sequential with instruction on the right first.
+
+`||'
+ Parallel
+ The D10V syntax allows either one instruction per line, one
+instruction per line with the execution symbol, or two instructions per
+line. For example
+`abs a1 -> abs r0'
+ Execute these sequentially. The instruction on the right is in
+ the right container and is executed second.
+
+`abs r0 <- abs a1'
+ Execute these reverse-sequentially. The instruction on the right
+ is in the right container, and is executed first.
+
+`ld2w r2,@r8+ || mac a0,r0,r7'
+ Execute these in parallel.
+
+`ld2w r2,@r8+ ||'
+`mac a0,r0,r7'
+ Two-line format. Execute these in parallel.
+
+`ld2w r2,@r8+'
+`mac a0,r0,r7'
+ Two-line format. Execute these sequentially. Assembler will put
+ them in the proper containers.
+
+`ld2w r2,@r8+ ->'
+`mac a0,r0,r7'
+ Two-line format. Execute these sequentially. Same as above but
+ second instruction will always go into right container.
+ Since `$' has no special meaning, you may use it in symbol names.

+......................
+
+You can use the predefined symbols `r0' through `r15' to refer to the
+D10V registers. You can also use `sp' as an alias for `r15'. The
+accumulators are `a0' and `a1'. There are special register-pair names

+the following refers to any of the numbered registers, but _not_ the
+control registers.
+`RN'
+ Register direct
+
+`@RN'
+ Register indirect
+
+`@RN+'

+......................
+
+Any symbol followed by `@word' will be replaced by the symbol's value
+shifted right by 2. This is used in situations such as loading a
+register with the address of a function (or any other code fragment).
+For example, if you want to load a register with the location of the
+function `main' then jump to that function, you could do it as follows:

+9.12.2.2 Register Names
+.......................
+
+You can use predefined symbols of the form `rNh' and `rNl' to refer to
+the H8/300 registers as sixteen 8-bit general-purpose registers. N is
+a digit from `0' to `7'); for instance, both `r0h' and `r7l' are valid
+register names.
+
+ You can also use the eight predefined symbols `rN' to refer to the
+H8/300 registers as 16-bit registers (you must use this form for
+addressing).
+
+ On the H8/300H, you can also use the eight predefined symbols `erN'
+(`er0' ... `er7') to refer to the 32-bit general purpose registers.
+
+ The two control registers are called `pc' (program counter; a 16-bit
+register, except on the H8/300H where it is 24 bits) and `ccr'
+(condition code register; an 8-bit register). `r7' is used as the
+stack pointer, and can also be called `sp'.

+`@rN'
+ Register indirect
+
+`@(D, rN)'
+`@(D:16, rN)'
+`@(D:24, rN)'
+ Register indirect: 16-bit or 24-bit displacement D from register
+ N. (24-bit displacements are only meaningful on the H8/300H.)
+
+`@rN+'
+ Register indirect with post-increment
+
+`@-rN'
+ Register indirect with pre-decrement
+
+``@'AA'
+``@'AA:8'
+``@'AA:16'
+``@'AA:24'
+ Absolute address `aa'. (The address size `:24' only makes sense
+ on the H8/300H.)
+
+`#XX'
+`#XX:8'
+`#XX:16'
+`#XX:32'
+ Immediate data XX. You may specify the `:8', `:16', or `:32' for
+ clarity, if you wish; but `as' neither requires this nor uses
+ it--the data size required is taken from context.
+
+``@'`@'AA'
+``@'`@'AA:8'
+ Memory indirect. You may specify the `:8' for clarity, if you
+ wish; but `as' neither requires this nor uses it.

+ the usual (16-bit) for the H8/300 family.
+
+ On the H8/300 family (including the H8/300H) `.word' directives
+generate 16-bit numbers.

+
+ Four H8/300 instructions (`add', `cmp', `mov', `sub') are defined
+with variants using the suffixes `.b', `.w', and `.l' to specify the
+size of a memory operand. `as' supports these suffixes, but does not
+require them; since one of the operands is always a register, `as' can
+deduce the correct size.
+
+ For example, since `r0' refers to a 16-bit register,
+ mov r0,@foo
+is equivalent to
+ mov.w r0,@foo
+
+ If you use the size suffixes, `as' issues a warning when the suffix
+and the register size do not match.

+9.13.1 Notes
+------------
+
+As a back end for GNU CC `as' has been throughly tested and should work
+extremely well. We have tested it only minimally on hand written
+assembly code and no one has tested it much on the assembly output from
+the HP compilers.
+
+ The format of the debugging sections has changed since the original
+`as' port (version 1.3X) was released; therefore, you must rebuild all
+HPPA objects and libraries with the new assembler so that you can debug
+the final executable.
+
+ The HPPA `as' port generates a small subset of the relocations
+available in the SOM and ELF object file formats. Additional relocation
+support will be added as it becomes necessary.
+
+
+File: as.info, Node: HPPA Options, Next: HPPA Syntax, Prev: HPPA Notes, Up: HPPA-Dependent
+
+9.13.2 Options
+--------------
+
+`as' has no machine-dependent command-line options for the HPPA.
+
+
+File: as.info, Node: HPPA Syntax, Next: HPPA Floating Point, Prev: HPPA Options, Up: HPPA-Dependent
+
+9.13.3 Syntax
+-------------
+
+The assembler syntax closely follows the HPPA instruction set reference
+manual; assembler directives and general syntax closely follow the HPPA
+assembly language reference manual, with a few noteworthy differences.
+
+ First, a colon may immediately follow a label definition. This is
+simply for compatibility with how most assembly language programmers
+write code.
+
+ Some obscure expression parsing problems may affect hand written
+code which uses the `spop' instructions, or code which makes significant
+use of the `!' line separator.
+
+ `as' is much less forgiving about missing arguments and other
+similar oversights than the HP assembler. `as' notifies you of missing
+arguments as syntax errors; this is regarded as a feature, not a bug.
+
+ Finally, `as' allows you to use an external symbol without
+explicitly importing the symbol. _Warning:_ in the future this will be
+an error for HPPA targets.
+
+ Special characters for HPPA targets include:
+
+ `;' is the line comment character.
+
+ `!' can be used instead of a newline to separate statements.
+
+ Since `$' has no special meaning, you may use it in symbol names.

+
+9.13.5 HPPA Assembler Directives
+--------------------------------
+
+`as' for the HPPA supports many additional directives for compatibility
+with the native assembler. This section describes them only briefly.
+For detailed information on HPPA-specific assembler directives, see
+`HP9000 Series 800 Assembly Language Reference Manual' (HP 92432-90001).
+
+ `as' does _not_ support the following assembler directives described
+in the HP manual:
+
+ .endm .liston
+ .enter .locct
+ .leave .macro
+ .listoff
+
+ Beyond those implemented for compatibility, `as' supports one
+additional assembler directive for the HPPA: `.param'. It conveys
+register argument locations for static functions. Its syntax closely
+follows the `.export' directive.
+
+ These are the additional directives in `as' for the HPPA:
+
+`.block N'
+`.blockz N'
+ Reserve N bytes of storage, and initialize them to zero.
+
+`.call'
+ Mark the beginning of a procedure call. Only the special case
+ with _no arguments_ is allowed.
+
+`.callinfo [ PARAM=VALUE, ... ] [ FLAG, ... ]'
+ Specify a number of parameters and flags that define the
+ environment for a procedure.
+
+ PARAM may be any of `frame' (frame size), `entry_gr' (end of
+ general register range), `entry_fr' (end of float register range),
+ `entry_sr' (end of space register range).
+
+ The values for FLAG are `calls' or `caller' (proc has
+ subroutines), `no_calls' (proc does not call subroutines),
+ `save_rp' (preserve return pointer), `save_sp' (proc preserves
+ stack pointer), `no_unwind' (do not unwind this proc), `hpux_int'
+ (proc is interrupt routine).
+
+`.code'
+ Assemble into the standard section called `$TEXT$', subsection
+ `$CODE$'.
+
+`.copyright "STRING"'
+ In the SOM object format, insert STRING into the object code,
+ marked as a copyright string.
+
+`.copyright "STRING"'
+ In the ELF object format, insert STRING into the object code,
+ marked as a version string.
+
+`.enter'
+ Not yet supported; the assembler rejects programs containing this
+ directive.
+
+`.entry'
+ Mark the beginning of a procedure.
+
+`.exit'
+ Mark the end of a procedure.
+
+`.export NAME [ ,TYP ] [ ,PARAM=R ]'
+ Make a procedure NAME available to callers. TYP, if present, must
+ be one of `absolute', `code' (ELF only, not SOM), `data', `entry',
+ `data', `entry', `millicode', `plabel', `pri_prog', or `sec_prog'.
+
+ PARAM, if present, provides either relocation information for the
+ procedure arguments and result, or a privilege level. PARAM may be
+ `argwN' (where N ranges from `0' to `3', and indicates one of four
+ one-word arguments); `rtnval' (the procedure's result); or
+ `priv_lev' (privilege level). For arguments or the result, R
+ specifies how to relocate, and must be one of `no' (not
+ relocatable), `gr' (argument is in general register), `fr' (in
+ floating point register), or `fu' (upper half of float register).
+ For `priv_lev', R is an integer.
+
+`.half N'
+ Define a two-byte integer constant N; synonym for the portable
+ `as' directive `.short'.
+
+`.import NAME [ ,TYP ]'
+ Converse of `.export'; make a procedure available to call. The
+ arguments use the same conventions as the first two arguments for
+ `.export'.
+
+`.label NAME'
+ Define NAME as a label for the current assembly location.
+
+`.leave'
+ Not yet supported; the assembler rejects programs containing this
+ directive.
+
+`.origin LC'
+ Advance location counter to LC. Synonym for the `as' portable
+ directive `.org'.
+
+`.param NAME [ ,TYP ] [ ,PARAM=R ]'
+ Similar to `.export', but used for static procedures.
+
+`.proc'
+ Use preceding the first statement of a procedure.
+
+`.procend'
+ Use following the last statement of a procedure.
+
+`LABEL .reg EXPR'
+ Synonym for `.equ'; define LABEL with the absolute expression EXPR
+ as its value.
+
+`.space SECNAME [ ,PARAMS ]'
+ Switch to section SECNAME, creating a new section by that name if
+ necessary. You may only use PARAMS when creating a new section,
+ not when switching to an existing one. SECNAME may identify a
+ section by number rather than by name.
+
+ If specified, the list PARAMS declares attributes of the section,
+ identified by keywords. The keywords recognized are `spnum=EXP'
+ (identify this section by the number EXP, an absolute expression),
+ `sort=EXP' (order sections according to this sort key when linking;
+ EXP is an absolute expression), `unloadable' (section contains no
+ loadable data), `notdefined' (this section defined elsewhere), and
+ `private' (data in this section not available to other programs).
+
+`.spnum SECNAM'
+ Allocate four bytes of storage, and initialize them with the
+ section number of the section named SECNAM. (You can define the
+ section number with the HPPA `.space' directive.)
+
+`.string "STR"'
+ Copy the characters in the string STR to the object file. *Note
+ Strings: Strings, for information on escape sequences you can use
+ in `as' strings.
+
+ _Warning!_ The HPPA version of `.string' differs from the usual
+ `as' definition: it does _not_ write a zero byte after copying STR.
+
+`.stringz "STR"'
+ Like `.string', but appends a zero byte after copying STR to object
+ file.
+
+`.subspa NAME [ ,PARAMS ]'
+`.nsubspa NAME [ ,PARAMS ]'
+ Similar to `.space', but selects a subsection NAME within the
+ current section. You may only specify PARAMS when you create a
+ subsection (in the first instance of `.subspa' for this NAME).
+
+ If specified, the list PARAMS declares attributes of the
+ subsection, identified by keywords. The keywords recognized are
+ `quad=EXPR' ("quadrant" for this subsection), `align=EXPR'
+ (alignment for beginning of this subsection; a power of two),
+ `access=EXPR' (value for "access rights" field), `sort=EXPR'
+ (sorting order for this subspace in link), `code_only' (subsection
+ contains only code), `unloadable' (subsection cannot be loaded
+ into memory), `comdat' (subsection is comdat), `common'
+ (subsection is common block), `dup_comm' (subsection may have
+ duplicate names), or `zero' (subsection is all zeros, do not write
+ in object file).
+
+ `.nsubspa' always creates a new subspace with the given name, even
+ if one with the same name already exists.
+
+ `comdat', `common' and `dup_comm' can be used to implement various
+ flavors of one-only support when using the SOM linker. The SOM
+ linker only supports specific combinations of these flags. The
+ details are not documented. A brief description is provided here.
+
+ `comdat' provides a form of linkonce support. It is useful for
+ both code and data subspaces. A `comdat' subspace has a key symbol
+ marked by the `is_comdat' flag or `ST_COMDAT'. Only the first
+ subspace for any given key is selected. The key symbol becomes
+ universal in shared links. This is similar to the behavior of
+ `secondary_def' symbols.
+
+ `common' provides Fortran named common support. It is only useful
+ for data subspaces. Symbols with the flag `is_common' retain this
+ flag in shared links. Referencing a `is_common' symbol in a shared
+ library from outside the library doesn't work. Thus, `is_common'
+ symbols must be output whenever they are needed.
+
+ `common' and `dup_comm' together provide Cobol common support.
+ The subspaces in this case must all be the same length.
+ Otherwise, this support is similar to the Fortran common support.
+
+ `dup_comm' by itself provides a type of one-only support for code.
+ Only the first `dup_comm' subspace is selected. There is a rather
+ complex algorithm to compare subspaces. Code symbols marked with
+ the `dup_common' flag are hidden. This support was intended for
+ "C++ duplicate inlines".
+
+ A simplified technique is used to mark the flags of symbols based
+ on the flags of their subspace. A symbol with the scope
+ SS_UNIVERSAL and type ST_ENTRY, ST_CODE or ST_DATA is marked with
+ the corresponding settings of `comdat', `common' and `dup_comm'
+ from the subspace, respectively. This avoids having to introduce
+ additional directives to mark these symbols. The HP assembler
+ sets `is_common' from `common'. However, it doesn't set the
+ `dup_common' from `dup_comm'. It doesn't have `comdat' support.
+
+`.version "STR"'
+ Write STR as version identifier in object code.

+9.14.1 Notes
+------------
+
+The ESA/390 `as' port is currently intended to be a back-end for the
+GNU CC compiler. It is not HLASM compatible, although it does support
+a subset of some of the HLASM directives. The only supported binary
+file format is ELF; none of the usual MVS/VM/OE/USS object file
+formats, such as ESD or XSD, are supported.
+
+ When used with the GNU CC compiler, the ESA/390 `as' will produce
+correct, fully relocated, functional binaries, and has been used to
+compile and execute large projects. However, many aspects should still
+be considered experimental; these include shared library support,
+dynamically loadable objects, and any relocation other than the 31-bit
+relocation.

+
+9.14.3 Syntax
+-------------
+
+The opcode/operand syntax follows the ESA/390 Principles of Operation
+manual; assembler directives and general syntax are loosely based on the
+prevailing AT&T/SVR4/ELF/Solaris style notation. HLASM-style directives
+are _not_ supported for the most part, with the exception of those
+described herein.
+
+ A leading dot in front of directives is optional, and the case of
+directives is ignored; thus for example, .using and USING have the same
+effect.
+
+ A colon may immediately follow a label definition. This is simply
+for compatibility with how most assembly language programmers write
+code.
+
+ `#' is the line comment character.
+
+ `;' can be used instead of a newline to separate statements.
+
+ Since `$' has no special meaning, you may use it in symbol names.
+
+ Registers can be given the symbolic names r0..r15, fp0, fp2, fp4,
+fp6. By using thesse symbolic names, `as' can detect simple syntax
+errors. The name rarg or r.arg is a synonym for r11, rtca or r.tca for
+r12, sp, r.sp, dsa r.dsa for r13, lr or r.lr for r14, rbase or r.base
+for r3 and rpgt or r.pgt for r4.
+
+ `*' is the current location counter. Unlike `.' it is always
+relative to the last USING directive. Note that this means that
+expressions cannot use multiplication, as any occurrence of `*' will be
+interpreted as a location counter.
+
+ All labels are relative to the last USING. Thus, branches to a label
+always imply the use of base+displacement.
+
+ Many of the usual forms of address constants / address literals are
+supported. Thus,
+ .using *,r3
+ L r15,=A(some_routine)
+ LM r6,r7,=V(some_longlong_extern)
+ A r1,=F'12'
+ AH r0,=H'42'
+ ME r6,=E'3.1416'
+ MD r6,=D'3.14159265358979'
+ O r6,=XL4'cacad0d0'
+ .ltorg
+ should all behave as expected: that is, an entry in the literal pool
+will be created (or reused if it already exists), and the instruction
+operands will be the displacement into the literal pool using the
+current base register (as last declared with the `.using' directive).

+
+9.14.5 ESA/390 Assembler Directives
+-----------------------------------
+
+`as' for the ESA/390 supports all of the standard ELF/SVR4 assembler
+directives that are documented in the main part of this documentation.
+Several additional directives are supported in order to implement the
+ESA/390 addressing model. The most important of these are `.using' and
+`.ltorg'
+
+ These are the additional directives in `as' for the ESA/390:
+
+`.dc'
+ A small subset of the usual DC directive is supported.
+
+`.drop REGNO'
+ Stop using REGNO as the base register. The REGNO must have been
+ previously declared with a `.using' directive in the same section
+ as the current section.
+
+`.ebcdic STRING'
+ Emit the EBCDIC equivalent of the indicated string. The emitted
+ string will be null terminated. Note that the directives
+ `.string' etc. emit ascii strings by default.
+
+`EQU'
+ The standard HLASM-style EQU directive is not supported; however,
+ the standard `as' directive .equ can be used to the same effect.
+
+`.ltorg'
+ Dump the literal pool accumulated so far; begin a new literal pool.
+ The literal pool will be written in the current section; in order
+ to generate correct assembly, a `.using' must have been previously
+ specified in the same section.
+
+`.using EXPR,REGNO'
+ Use REGNO as the base register for all subsequent RX, RS, and SS
+ form instructions. The EXPR will be evaluated to obtain the base
+ address; usually, EXPR will merely be `*'.
+
+ This assembler allows two `.using' directives to be simultaneously
+ outstanding, one in the `.text' section, and one in another section
+ (typically, the `.data' section). This feature allows dynamically
+ loaded objects to be implemented in a relatively straightforward
+ way. A `.using' directive must always be specified in the `.text'
+ section; this will specify the base register that will be used for
+ branches in the `.text' section. A second `.using' may be
+ specified in another section; this will specify the base register
+ that is used for non-label address literals. When a second
+ `.using' is specified, then the subsequent `.ltorg' must be put in
+ the same section; otherwise an error will result.
+
+ Thus, for example, the following code uses `r3' to address branch
+ targets and `r4' to address the literal pool, which has been
+ written to the `.data' section. The is, the constants
+ `=A(some_routine)', `=H'42'' and `=E'3.1416'' will all appear in
+ the `.data' section.
+
+ .data
+ .using LITPOOL,r4
+ .text
+ BASR r3,0
+ .using *,r3
+ B START
+ .long LITPOOL
+ START:
+ L r4,4(,r3)
+ L r15,=A(some_routine)
+ LTR r15,r15
+ BNE LABEL
+ AH r0,=H'42'
+ LABEL:
+ ME r6,=E'3.1416'
+ .data
+ LITPOOL:
+ .ltorg
+
+ Note that this dual-`.using' directive semantics extends and is
+ not compatible with HLASM semantics. Note that this assembler
+ directive does not support the full range of HLASM semantics.

+
+9.15.1 Options
+--------------
+
+The i386 version of `as' has a few machine dependent options:
+
+`--32 | --x32 | --64'
+ Select the word size, either 32 bits or 64 bits. `--32' implies
+ Intel i386 architecture, while `--x32' and `--64' imply AMD x86-64
+ architecture with 32-bit or 64-bit word-size respectively.
+
+ These options are only available with the ELF object file format,
+ and require that the necessary BFD support has been included (on a
+ 32-bit platform you have to add -enable-64-bit-bfd to configure
+ enable 64-bit usage and use x86-64 as target platform).
+
+`-n'
+ By default, x86 GAS replaces multiple nop instructions used for
+ alignment within code sections with multi-byte nop instructions
+ such as leal 0(%esi,1),%esi. This switch disables the
+ optimization.
+
+`--divide'
+ On SVR4-derived platforms, the character `/' is treated as a
+ comment character, which means that it cannot be used in
+ expressions. The `--divide' option turns `/' into a normal
+ character. This does not disable `/' at the beginning of a line
+ starting a comment, or affect using `#' for starting a comment.
+
+`-march=CPU[+EXTENSION...]'
+ This option specifies the target processor. The assembler will
+ issue an error message if an attempt is made to assemble an
+ instruction which will not execute on the target processor. The
+ following processor names are recognized: `i8086', `i186', `i286',
+ `i386', `i486', `i586', `i686', `pentium', `pentiumpro',
+ `pentiumii', `pentiumiii', `pentium4', `prescott', `nocona',
+ `core', `core2', `corei7', `l1om', `k1om', `k6', `k6_2', `athlon',
+ `opteron', `k8', `amdfam10', `bdver1', `bdver2', `bdver3',
+ `bdver4', `btver1', `btver2', `generic32' and `generic64'.
+
+ In addition to the basic instruction set, the assembler can be
+ told to accept various extension mnemonics. For example,
+ `-march=i686+sse4+vmx' extends I686 with SSE4 and VMX. The
+ following extensions are currently supported: `8087', `287', `387',
+ `no87', `mmx', `nommx', `sse', `sse2', `sse3', `ssse3', `sse4.1',
+ `sse4.2', `sse4', `nosse', `avx', `avx2', `adx', `rdseed',
+ `prfchw', `smap', `mpx', `sha', `prefetchwt1', `clflushopt', `se1',
+ `clwb', `pcommit', `avx512f', `avx512cd', `avx512er', `avx512pf',
+ `avx512vl', `avx512bw', `avx512dq', `avx512ifma', `avx512vbmi',
+ `noavx', `vmx', `vmfunc', `smx', `xsave', `xsaveopt', `xsavec',
+ `xsaves', `aes', `pclmul', `fsgsbase', `rdrnd', `f16c', `bmi2',
+ `fma', `movbe', `ept', `lzcnt', `hle', `rtm', `invpcid', `clflush',
+ `lwp', `fma4', `xop', `cx16', `syscall', `rdtscp', `3dnow',
+ `3dnowa', `sse4a', `sse5', `svme', `abm' and `padlock'. Note that
+ rather than extending a basic instruction set, the extension
+ mnemonics starting with `no' revoke the respective functionality.
+
+ When the `.arch' directive is used with `-march', the `.arch'
+ directive will take precedent.
+
+`-mtune=CPU'
+ This option specifies a processor to optimize for. When used in
+ conjunction with the `-march' option, only instructions of the
+ processor specified by the `-march' option will be generated.
+
+ Valid CPU values are identical to the processor list of
+ `-march=CPU'.
+
+`-msse2avx'
+ This option specifies that the assembler should encode SSE
+ instructions with VEX prefix.
+
+`-msse-check=NONE'
+`-msse-check=WARNING'
+`-msse-check=ERROR'
+ These options control if the assembler should check SSE
+ instructions. `-msse-check=NONE' will make the assembler not to
+ check SSE instructions, which is the default.
+ `-msse-check=WARNING' will make the assembler issue a warning for
+ any SSE instruction. `-msse-check=ERROR' will make the assembler
+ issue an error for any SSE instruction.
+
+`-mavxscalar=128'
+`-mavxscalar=256'
+ These options control how the assembler should encode scalar AVX
+ instructions. `-mavxscalar=128' will encode scalar AVX
+ instructions with 128bit vector length, which is the default.
+ `-mavxscalar=256' will encode scalar AVX instructions with 256bit
+ vector length.
+
+`-mevexlig=128'
+`-mevexlig=256'
+`-mevexlig=512'
+ These options control how the assembler should encode
+ length-ignored (LIG) EVEX instructions. `-mevexlig=128' will
+ encode LIG EVEX instructions with 128bit vector length, which is
+ the default. `-mevexlig=256' and `-mevexlig=512' will encode LIG
+ EVEX instructions with 256bit and 512bit vector length,
+ respectively.
+
+`-mevexwig=0'
+`-mevexwig=1'
+ These options control how the assembler should encode w-ignored
+ (WIG) EVEX instructions. `-mevexwig=0' will encode WIG EVEX
+ instructions with evex.w = 0, which is the default. `-mevexwig=1'
+ will encode WIG EVEX instructions with evex.w = 1.
+
+`-mmnemonic=ATT'
+`-mmnemonic=INTEL'
+ This option specifies instruction mnemonic for matching
+ instructions. The `.att_mnemonic' and `.intel_mnemonic'
+ directives will take precedent.
+
+`-msyntax=ATT'
+`-msyntax=INTEL'
+ This option specifies instruction syntax when processing
+ instructions. The `.att_syntax' and `.intel_syntax' directives
+ will take precedent.
+
+`-mnaked-reg'
+ This opetion specifies that registers don't require a `%' prefix.
+ The `.att_syntax' and `.intel_syntax' directives will take
+ precedent.
+
+`-madd-bnd-prefix'
+ This option forces the assembler to add BND prefix to all
+ branches, even if such prefix was not explicitly specified in the
+ source code.
+
+`-mbig-obj'
+ On x86-64 PE/COFF target this option forces the use of big object
+ file format, which allows more than 32768 sections.
+
+`-momit-lock-prefix=NO'
+`-momit-lock-prefix=YES'
+ These options control how the assembler should encode lock prefix.
+ This option is intended as a workaround for processors, that fail
+ on lock prefix. This option can only be safely used with
+ single-core, single-thread computers `-momit-lock-prefix=YES' will
+ omit all lock prefixes. `-momit-lock-prefix=NO' will encode lock
+ prefix as usual, which is the default.
+
+`-mevexrcig=RNE'
+`-mevexrcig=RD'
+`-mevexrcig=RU'
+`-mevexrcig=RZ'
+ These options control how the assembler should encode SAE-only
+ EVEX instructions. `-mevexrcig=RNE' will encode RC bits of EVEX
+ instruction with 00, which is the default. `-mevexrcig=RD',
+ `-mevexrcig=RU' and `-mevexrcig=RZ' will encode SAE-only EVEX
+ instructions with 01, 10 and 11 RC bits, respectively.

+
+9.15.3.1 AT&T Syntax versus Intel Syntax
+........................................
+
+`as' now supports assembly using Intel assembler syntax.
+`.intel_syntax' selects Intel mode, and `.att_syntax' switches back to
+the usual AT&T mode for compatibility with the output of `gcc'. Either
+of these directives may have an optional argument, `prefix', or
+`noprefix' specifying whether registers require a `%' prefix. AT&T
+System V/386 assembler syntax is quite different from Intel syntax. We
+mention these differences because almost all 80386 documents use Intel
+syntax. Notable differences between the two syntaxes are:
+
+ * AT&T immediate operands are preceded by `$'; Intel immediate
+ operands are undelimited (Intel `push 4' is AT&T `pushl $4').
+ AT&T register operands are preceded by `%'; Intel register operands
+ are undelimited. AT&T absolute (as opposed to PC relative)
+ jump/call operands are prefixed by `*'; they are undelimited in
+ Intel syntax.
+
+ * AT&T and Intel syntax use the opposite order for source and
+ destination operands. Intel `add eax, 4' is `addl $4, %eax'. The
+ `source, dest' convention is maintained for compatibility with
+ previous Unix assemblers. Note that `bound', `invlpga', and
+ instructions with 2 immediate operands, such as the `enter'
+ instruction, do _not_ have reversed order. *Note i386-Bugs::.
+
+ * In AT&T syntax the size of memory operands is determined from the
+ last character of the instruction mnemonic. Mnemonic suffixes of
+ `b', `w', `l' and `q' specify byte (8-bit), word (16-bit), long
+ (32-bit) and quadruple word (64-bit) memory references. Intel
+ syntax accomplishes this by prefixing memory operands (_not_ the
+ instruction mnemonics) with `byte ptr', `word ptr', `dword ptr'
+ and `qword ptr'. Thus, Intel `mov al, byte ptr FOO' is `movb FOO,
+ %al' in AT&T syntax.
+
+ In 64-bit code, `movabs' can be used to encode the `mov'
+ instruction with the 64-bit displacement or immediate operand.
+
+ * Immediate form long jumps and calls are `lcall/ljmp $SECTION,
+ $OFFSET' in AT&T syntax; the Intel syntax is `call/jmp far
+ SECTION:OFFSET'. Also, the far return instruction is `lret
+ $STACK-ADJUST' in AT&T syntax; Intel syntax is `ret far
+ STACK-ADJUST'.
+
+ * The AT&T assembler does not provide support for multiple section
+ programs. Unix style systems expect all programs to be single
+ sections.

+
+9.15.3.2 Special Characters
+...........................
+
+The presence of a `#' appearing anywhere on a line indicates the start
+of a comment that extends to the end of that line.
+
+ If a `#' appears as the first character of a line then the whole
+line is treated as a comment, but in this case the line can also be a
+logical line number directive (*note Comments::) or a preprocessor
+control command (*note Preprocessing::).
+
+ If the `--divide' command line option has not been specified then
+the `/' character appearing anywhere on a line also introduces a line
+comment.
+
+ The `;' character can be used to separate statements on the same
+line.

+
+9.15.4 Instruction Naming
+-------------------------
+
+Instruction mnemonics are suffixed with one character modifiers which
+specify the size of operands. The letters `b', `w', `l' and `q'
+specify byte, word, long and quadruple word operands. If no suffix is
+specified by an instruction then `as' tries to fill in the missing
+suffix based on the destination register operand (the last one by
+convention). Thus, `mov %ax, %bx' is equivalent to `movw %ax, %bx';
+also, `mov $1, %bx' is equivalent to `movw $1, bx'. Note that this is
+incompatible with the AT&T Unix assembler which assumes that a missing
+mnemonic suffix implies long operand size. (This incompatibility does
+not affect compiler output since compilers always explicitly specify
+the mnemonic suffix.)
+
+ Almost all instructions have the same names in AT&T and Intel format.
+There are a few exceptions. The sign extend and zero extend
+instructions need two sizes to specify them. They need a size to
+sign/zero extend _from_ and a size to zero extend _to_. This is
+accomplished by using two instruction mnemonic suffixes in AT&T syntax.
+Base names for sign extend and zero extend are `movs...' and `movz...'
+in AT&T syntax (`movsx' and `movzx' in Intel syntax). The instruction
+mnemonic suffixes are tacked on to this base name, the _from_ suffix
+before the _to_ suffix. Thus, `movsbl %al, %edx' is AT&T syntax for
+"move sign extend _from_ %al _to_ %edx." Possible suffixes, thus, are
+`bl' (from byte to long), `bw' (from byte to word), `wl' (from word to
+long), `bq' (from byte to quadruple word), `wq' (from word to quadruple
+word), and `lq' (from long to quadruple word).
+
+ Different encoding options can be specified via optional mnemonic
+suffix. `.s' suffix swaps 2 register operands in encoding when moving
+from one register to another. `.d8' or `.d32' suffix prefers 8bit or
+32bit displacement in encoding.
+
+ The Intel-syntax conversion instructions
+
+ * `cbw' -- sign-extend byte in `%al' to word in `%ax',
+
+ * `cwde' -- sign-extend word in `%ax' to long in `%eax',
+
+ * `cwd' -- sign-extend word in `%ax' to long in `%dx:%ax',
+
+ * `cdq' -- sign-extend dword in `%eax' to quad in `%edx:%eax',
+
+ * `cdqe' -- sign-extend dword in `%eax' to quad in `%rax' (x86-64
+ only),
+
+ * `cqo' -- sign-extend quad in `%rax' to octuple in `%rdx:%rax'
+ (x86-64 only),
+
+are called `cbtw', `cwtl', `cwtd', `cltd', `cltq', and `cqto' in AT&T
+naming. `as' accepts either naming for these instructions.
+
+ Far call/jump instructions are `lcall' and `ljmp' in AT&T syntax,
+but are `call far' and `jump far' in Intel convention.
+
+9.15.5 AT&T Mnemonic versus Intel Mnemonic
+------------------------------------------
+
+`as' supports assembly using Intel mnemonic. `.intel_mnemonic' selects
+Intel mnemonic with Intel syntax, and `.att_mnemonic' switches back to
+the usual AT&T mnemonic with AT&T syntax for compatibility with the
+output of `gcc'. Several x87 instructions, `fadd', `fdiv', `fdivp',
+`fdivr', `fdivrp', `fmul', `fsub', `fsubp', `fsubr' and `fsubrp', are
+implemented in AT&T System V/386 assembler with different mnemonics
+from those in Intel IA32 specification. `gcc' generates those
+instructions with AT&T mnemonic.

+
+9.15.6 Register Naming
+----------------------
+
+Register operands are always prefixed with `%'. The 80386 registers
+consist of
+
+ * the 8 32-bit registers `%eax' (the accumulator), `%ebx', `%ecx',
+ `%edx', `%edi', `%esi', `%ebp' (the frame pointer), and `%esp'
+ (the stack pointer).
+
+ * the 8 16-bit low-ends of these: `%ax', `%bx', `%cx', `%dx', `%di',
+ `%si', `%bp', and `%sp'.
+
+ * the 8 8-bit registers: `%ah', `%al', `%bh', `%bl', `%ch', `%cl',
+ `%dh', and `%dl' (These are the high-bytes and low-bytes of `%ax',
+ `%bx', `%cx', and `%dx')
+
+ * the 6 section registers `%cs' (code section), `%ds' (data
+ section), `%ss' (stack section), `%es', `%fs', and `%gs'.
+
+ * the 3 processor control registers `%cr0', `%cr2', and `%cr3'.
+
+ * the 6 debug registers `%db0', `%db1', `%db2', `%db3', `%db6', and
+ `%db7'.
+
+ * the 2 test registers `%tr6' and `%tr7'.
+
+ * the 8 floating point register stack `%st' or equivalently
+ `%st(0)', `%st(1)', `%st(2)', `%st(3)', `%st(4)', `%st(5)',
+ `%st(6)', and `%st(7)'. These registers are overloaded by 8 MMX
+ registers `%mm0', `%mm1', `%mm2', `%mm3', `%mm4', `%mm5', `%mm6'
+ and `%mm7'.
+
+ * the 8 SSE registers registers `%xmm0', `%xmm1', `%xmm2', `%xmm3',
+ `%xmm4', `%xmm5', `%xmm6' and `%xmm7'.
+
+ The AMD x86-64 architecture extends the register set by:
+
+ * enhancing the 8 32-bit registers to 64-bit: `%rax' (the
+ accumulator), `%rbx', `%rcx', `%rdx', `%rdi', `%rsi', `%rbp' (the
+ frame pointer), `%rsp' (the stack pointer)
+
+ * the 8 extended registers `%r8'-`%r15'.
+
+ * the 8 32-bit low ends of the extended registers: `%r8d'-`%r15d'
+
+ * the 8 16-bit low ends of the extended registers: `%r8w'-`%r15w'
+
+ * the 8 8-bit low ends of the extended registers: `%r8b'-`%r15b'
+
+ * the 4 8-bit registers: `%sil', `%dil', `%bpl', `%spl'.
+
+ * the 8 debug registers: `%db8'-`%db15'.
+
+ * the 8 SSE registers: `%xmm8'-`%xmm15'.

+
+9.15.7 Instruction Prefixes
+---------------------------
+
+Instruction prefixes are used to modify the following instruction. They
+are used to repeat string instructions, to provide section overrides, to
+perform bus lock operations, and to change operand and address sizes.
+(Most instructions that normally operate on 32-bit operands will use
+16-bit operands if the instruction has an "operand size" prefix.)
+Instruction prefixes are best written on the same line as the
+instruction they act upon. For example, the `scas' (scan string)
+instruction is repeated with:
+
+ repne scas %es:(%edi),%al
+
+ You may also place prefixes on the lines immediately preceding the
+instruction, but this circumvents checks that `as' does with prefixes,
+and will not work with all prefixes.
+
+ Here is a list of instruction prefixes:
+
+ * Section override prefixes `cs', `ds', `ss', `es', `fs', `gs'.
+ These are automatically added by specifying using the
+ SECTION:MEMORY-OPERAND form for memory references.
+
+ * Operand/Address size prefixes `data16' and `addr16' change 32-bit
+ operands/addresses into 16-bit operands/addresses, while `data32'
+ and `addr32' change 16-bit ones (in a `.code16' section) into
+ 32-bit operands/addresses. These prefixes _must_ appear on the
+ same line of code as the instruction they modify. For example, in
+ a 16-bit `.code16' section, you might write:
+
+ addr32 jmpl *(%ebx)
+
+ * The bus lock prefix `lock' inhibits interrupts during execution of
+ the instruction it precedes. (This is only valid with certain
+ instructions; see a 80386 manual for details).
+
+ * The wait for coprocessor prefix `wait' waits for the coprocessor to
+ complete the current instruction. This should never be needed for
+ the 80386/80387 combination.
+
+ * The `rep', `repe', and `repne' prefixes are added to string
+ instructions to make them repeat `%ecx' times (`%cx' times if the
+ current address size is 16-bits).
+
+ * The `rex' family of prefixes is used by x86-64 to encode
+ extensions to i386 instruction set. The `rex' prefix has four
+ bits -- an operand size overwrite (`64') used to change operand
+ size from 32-bit to 64-bit and X, Y and Z extensions bits used to
+ extend the register set.
+
+ You may write the `rex' prefixes directly. The `rex64xyz'
+ instruction emits `rex' prefix with all the bits set. By omitting
+ the `64', `x', `y' or `z' you may write other prefixes as well.
+ Normally, there is no need to write the prefixes explicitly, since
+ gas will automatically generate them based on the instruction
+ operands.

+
+9.15.8 Memory References
+------------------------
+
+An Intel syntax indirect memory reference of the form
+
+ SECTION:[BASE + INDEX*SCALE + DISP]
+
+is translated into the AT&T syntax
+
+ SECTION:DISP(BASE, INDEX, SCALE)
+
+where BASE and INDEX are the optional 32-bit base and index registers,
+DISP is the optional displacement, and SCALE, taking the values 1, 2,
+4, and 8, multiplies INDEX to calculate the address of the operand. If
+no SCALE is specified, SCALE is taken to be 1. SECTION specifies the
+optional section register for the memory operand, and may override the
+default section register (see a 80386 manual for section register
+defaults). Note that section overrides in AT&T syntax _must_ be
+preceded by a `%'. If you specify a section override which coincides
+with the default section register, `as' does _not_ output any section
+register override prefixes to assemble the given instruction. Thus,
+section overrides can be specified to emphasize which section register
+is used for a given memory operand.
+
+ Here are some examples of Intel and AT&T style memory references:
+
+AT&T: `-4(%ebp)', Intel: `[ebp - 4]'
+ BASE is `%ebp'; DISP is `-4'. SECTION is missing, and the default
+ section is used (`%ss' for addressing with `%ebp' as the base
+ register). INDEX, SCALE are both missing.
+
+AT&T: `foo(,%eax,4)', Intel: `[foo + eax*4]'
+ INDEX is `%eax' (scaled by a SCALE 4); DISP is `foo'. All other
+ fields are missing. The section register here defaults to `%ds'.
+
+AT&T: `foo(,1)'; Intel `[foo]'
+ This uses the value pointed to by `foo' as a memory operand. Note
+ that BASE and INDEX are both missing, but there is only _one_ `,'.
+ This is a syntactic exception.
+
+AT&T: `%gs:foo'; Intel `gs:foo'
+ This selects the contents of the variable `foo' with section
+ register SECTION being `%gs'.
+
+ Absolute (as opposed to PC relative) call and jump operands must be
+prefixed with `*'. If no `*' is specified, `as' always chooses PC
+relative addressing for jump/call labels.
+
+ Any instruction that has a memory operand, but no register operand,
+_must_ specify its size (byte, word, long, or quadruple) with an
+instruction mnemonic suffix (`b', `w', `l' or `q', respectively).
+
+ The x86-64 architecture adds an RIP (instruction pointer relative)
+addressing. This addressing mode is specified by using `rip' as a base
+register. Only constant offsets are valid. For example:
+
+AT&T: `1234(%rip)', Intel: `[rip + 1234]'
+ Points to the address 1234 bytes past the end of the current
+ instruction.
+
+AT&T: `symbol(%rip)', Intel: `[rip + symbol]'
+ Points to the `symbol' in RIP relative way, this is shorter than
+ the default absolute addressing.
+
+ Other addressing modes remain unchanged in x86-64 architecture,
+except registers used are 64-bit instead of 32-bit.

+
+9.15.9 Handling of Jump Instructions
+------------------------------------
+
+Jump instructions are always optimized to use the smallest possible
+displacements. This is accomplished by using byte (8-bit) displacement
+jumps whenever the target is sufficiently close. If a byte displacement
+is insufficient a long displacement is used. We do not support word
+(16-bit) displacement jumps in 32-bit mode (i.e. prefixing the jump
+instruction with the `data16' instruction prefix), since the 80386
+insists upon masking `%eip' to 16 bits after the word displacement is
+added. (See also *note i386-Arch::)
+
+ Note that the `jcxz', `jecxz', `loop', `loopz', `loope', `loopnz'
+and `loopne' instructions only come in byte displacements, so that if
+you use these instructions (`gcc' does not use them) you may get an
+error message (and incorrect code). The AT&T 80386 assembler tries to
+get around this problem by expanding `jcxz foo' to
+
+ jcxz cx_zero
+ jmp cx_nonzero
+ cx_zero: jmp foo
+ cx_nonzero:

+
+9.15.10 Floating Point
+----------------------
+
+All 80387 floating point types except packed BCD are supported. (BCD
+support may be added without much difficulty). These data types are
+16-, 32-, and 64- bit integers, and single (32-bit), double (64-bit),
+and extended (80-bit) precision floating point. Each supported type
+has an instruction mnemonic suffix and a constructor associated with
+it. Instruction mnemonic suffixes specify the operand's data type.
+Constructors build these data types into memory.
+
+ * Floating point constructors are `.float' or `.single', `.double',
+ and `.tfloat' for 32-, 64-, and 80-bit formats. These correspond
+ to instruction mnemonic suffixes `s', `l', and `t'. `t' stands for
+ 80-bit (ten byte) real. The 80387 only supports this format via
+ the `fldt' (load 80-bit real to stack top) and `fstpt' (store
+ 80-bit real and pop stack) instructions.
+
+ * Integer constructors are `.word', `.long' or `.int', and `.quad'
+ for the 16-, 32-, and 64-bit integer formats. The corresponding
+ instruction mnemonic suffixes are `s' (single), `l' (long), and
+ `q' (quad). As with the 80-bit real format, the 64-bit `q' format
+ is only present in the `fildq' (load quad integer to stack top)
+ and `fistpq' (store quad integer and pop stack) instructions.
+
+ Register to register operations should not use instruction mnemonic
+suffixes. `fstl %st, %st(1)' will give a warning, and be assembled as
+if you wrote `fst %st, %st(1)', since all register to register
+operations use 80-bit floating point operands. (Contrast this with
+`fstl %st, mem', which converts `%st' from 80-bit to 64-bit floating
+point format, then stores the result in the 4 byte location `mem')

+9.15.11 Intel's MMX and AMD's 3DNow! SIMD Operations
+----------------------------------------------------
+
+`as' supports Intel's MMX instruction set (SIMD instructions for
+integer data), available on Intel's Pentium MMX processors and Pentium
+II processors, AMD's K6 and K6-2 processors, Cyrix' M2 processor, and
+probably others. It also supports AMD's 3DNow! instruction set (SIMD
+instructions for 32-bit floating point data) available on AMD's K6-2
+processor and possibly others in the future.
+
+ Currently, `as' does not support Intel's floating point SIMD, Katmai
+(KNI).
+
+ The eight 64-bit MMX operands, also used by 3DNow!, are called
+`%mm0', `%mm1', ... `%mm7'. They contain eight 8-bit integers, four
+16-bit integers, two 32-bit integers, one 64-bit integer, or two 32-bit
+floating point values. The MMX registers cannot be used at the same
+time as the floating point stack.
+
+ See Intel and AMD documentation, keeping in mind that the operand
+order in instructions is reversed from the Intel syntax.

+9.15.12 AMD's Lightweight Profiling Instructions
+------------------------------------------------
+
+`as' supports AMD's Lightweight Profiling (LWP) instruction set,
+available on AMD's Family 15h (Orochi) processors.
+
+ LWP enables applications to collect and manage performance data, and
+react to performance events. The collection of performance data
+requires no context switches. LWP runs in the context of a thread and
+so several counters can be used independently across multiple threads.
+LWP can be used in both 64-bit and legacy 32-bit modes.
+
+ For detailed information on the LWP instruction set, see the `AMD
+Lightweight Profiling Specification' available at Lightweight Profiling
+Specification (http://developer.amd.com/cpu/LWP).

+----------------------------------------------------
+
+`as' supports AMD's Trailing Bit Manipulation (TBM) instruction set,

+
+ TBM instructions provide instructions implementing individual bit
+manipulation operations such as isolating, masking, setting, resetting,

+
+9.15.15 Writing 16-bit Code
+---------------------------
+
+While `as' normally writes only "pure" 32-bit i386 code or 64-bit
+x86-64 code depending on the default configuration, it also supports
+writing code to run in real mode or in 16-bit protected mode code
+segments. To do this, put a `.code16' or `.code16gcc' directive before
+the assembly language instructions to be run in 16-bit mode. You can
+switch `as' to writing 32-bit code with the `.code32' directive or
+64-bit code with the `.code64' directive.
+
+ `.code16gcc' provides experimental support for generating 16-bit
+code from gcc, and differs from `.code16' in that `call', `ret',
+`enter', `leave', `push', `pop', `pusha', `popa', `pushf', and `popf'
+instructions default to 32-bit size. This is so that the stack pointer
+is manipulated in the same way over function calls, allowing access to
+function parameters at the same stack offsets as in 32-bit mode.
+`.code16gcc' also automatically adds address size prefixes where
+necessary to use the 32-bit addressing modes that gcc generates.
+
+ The code which `as' generates in 16-bit mode will not necessarily
+run on a 16-bit pre-80386 processor. To write code that runs on such a
+processor, you must refrain from using _any_ 32-bit constructs which
+require `as' to output address or operand size prefixes.
+
+ Note that writing 16-bit code instructions by explicitly specifying a
+prefix or an instruction mnemonic suffix within a 32-bit code section
+generates different machine instructions than those generated for a
+16-bit code segment. In a 32-bit code section, the following code
+generates the machine opcode bytes `66 6a 04', which pushes the value
+`4' onto the stack, decrementing `%esp' by 2.
+
+ pushw $4
+
+ The same code in a 16-bit code section would generate the machine
+opcode bytes `6a 04' (i.e., without the operand size prefix), which is
+correct since the processor default operand size is assumed to be 16
+bits in a 16-bit code section.

+
+9.15.16 AT&T Syntax bugs
+------------------------
+
+The UnixWare assembler, and probably other AT&T derived ix86 Unix
+assemblers, generate floating point instructions with reversed source
+and destination registers in certain cases. Unfortunately, gcc and
+possibly many other programs use this reversed syntax, so we're stuck
+with it.
+
+ For example
+
+ fsub %st,%st(3)
+ results in `%st(3)' being updated to `%st - %st(3)' rather than the
+expected `%st(3) - %st'. This happens with all the non-commutative
+arithmetic floating point operations with two register operands where
+the source register is `%st' and the destination register is `%st(i)'.

+
+9.15.17 Specifying CPU Architecture
+-----------------------------------
+
+`as' may be told to assemble for a particular CPU (sub-)architecture
+with the `.arch CPU_TYPE' directive. This directive enables a warning
+when gas detects an instruction that is not supported on the CPU
+specified. The choices for CPU_TYPE are:
+
+`i8086' `i186' `i286' `i386'
+`i486' `i586' `i686' `pentium'
+`pentiumpro' `pentiumii' `pentiumiii' `pentium4'

+`k6' `k6_2' `athlon' `k8'
+`amdfam10' `bdver1' `bdver2' `bdver3'
+`bdver4' `btver1' `btver2'
+`generic32' `generic64'
+`.mmx' `.sse' `.sse2' `.sse3'
+`.ssse3' `.sse4.1' `.sse4.2' `.sse4'
+`.avx' `.vmx' `.smx' `.ept'
+`.clflush' `.movbe' `.xsave' `.xsaveopt'
+`.aes' `.pclmul' `.fma' `.fsgsbase'
+`.rdrnd' `.f16c' `.avx2' `.bmi2'
+`.lzcnt' `.invpcid' `.vmfunc' `.hle'
+`.rtm' `.adx' `.rdseed' `.prfchw'
+`.smap' `.mpx' `.sha' `.prefetchwt1'
+`.clflushopt' `.xsavec' `.xsaves' `.se1'
+`.avx512f' `.avx512cd' `.avx512er' `.avx512pf'
+`.avx512vl' `.avx512bw' `.avx512dq' `.avx512ifma'
+`.avx512vbmi' `.clwb' `.pcommit'

+`.syscall' `.rdtscp' `.svme' `.abm'
+`.lwp' `.fma4' `.xop' `.cx16'
+`.padlock'
+
+ Apart from the warning, there are only two other effects on `as'
+operation; Firstly, if you specify a CPU other than `i486', then shift
+by one instructions such as `sarl $1, %eax' will automatically use a
+two byte opcode sequence. The larger three byte opcode sequence is
+used on the 486 (and when no architecture is specified) because it
+executes faster on the 486. Note that you can explicitly request the
+two byte opcode by writing `sarl %eax'. Secondly, if you specify
+`i8086', `i186', or `i286', _and_ `.code16' or `.code16gcc' then byte
+offset conditional jumps will be promoted when necessary to a two
+instruction sequence consisting of a conditional jump of the opposite
+sense around an unconditional jump to the target.
+
+ Following the CPU architecture (but not a sub-architecture, which
+are those starting with a dot), you may specify `jumps' or `nojumps' to
+control automatic promotion of conditional jumps. `jumps' is the
+default, and enables jump promotion; All external jumps will be of the
+long variety, and file-local jumps will be promoted as necessary.
+(*note i386-Jumps::) `nojumps' leaves external conditional jumps as
+byte offset jumps, and warns about file-local conditional jumps that
+`as' promotes. Unconditional jumps are treated as for `jumps'.

+9.15.18 Notes
+-------------
+
+There is some trickery concerning the `mul' and `imul' instructions
+that deserves mention. The 16-, 32-, 64- and 128-bit expanding
+multiplies (base opcode `0xf6'; extension 4 for `mul' and 5 for `imul')
+can be output only in the one operand form. Thus, `imul %ebx, %eax'
+does _not_ select the expanding multiply; the expanding multiply would
+clobber the `%edx' register, and this would confuse `gcc' output. Use
+`imul %ebx' to get the 64-bit product in `%edx:%eax'.
+
+ We have added a two operand form of `imul' when the first operand is
+an immediate mode expression and the second operand is a register.
+This is just a shorthand, so that, multiplying `%eax' by 69, for
+example, can be done with `imul $69, %eax' rather than `imul $69, %eax,
+%eax'.

+ Both the Intel and AT&T/SVR4 syntaxes are supported, with the latter
+being the default. One difference is that AT&T syntax requires the '%'
+prefix on register names while Intel syntax does not. Another
+difference is in the specification of relocatable expressions. The
+Intel syntax is `ha%expression' whereas the SVR4 syntax is
+`[expression]@ha' (and similarly for the "l" and "h" selectors).

+
+All of the Intel i860XR and i860XP machine instructions are supported.

+or _i860 Microprocessor Architecture_ for more information.
+
+9.16.4.1 Other instruction support (pseudo-instructions)
+........................................................
+
+For compatibility with some other i860 assemblers, a number of
+pseudo-instructions are supported. While these are supported, they are
+a very undesirable feature that should be avoided - in particular, when
+they result in an expansion to multiple actual i860 instructions. Below
+are the pseudo-instructions that result in expansions.
+ * Load large immediate into general register:
+
+ The pseudo-instruction `mov imm,%rn' (where the immediate does not
+ fit within a signed 16-bit field) will be expanded into:
+ orh large_imm@h,%r0,%rn
+ or large_imm@l,%rn,%rn
+
+ * Load/store with relocatable address expression:
+
+ For example, the pseudo-instruction `ld.b addr_exp(%rx),%rn' will
+ be expanded into:
+ orh addr_exp@ha,%rx,%r31
+ ld.l addr_exp@l(%r31),%rn
+
+ The analogous expansions apply to `ld.x, st.x, fld.x, pfld.x,
+ fst.x', and `pst.x' as well.
+
+ * Signed large immediate with add/subtract:
+
+ If any of the arithmetic operations `adds, addu, subs, subu' are
+ used with an immediate larger than 16-bits (signed), then they
+ will be expanded. For instance, the pseudo-instruction `adds
+ large_imm,%rx,%rn' expands to:
+ orh large_imm@h,%r0,%r31
+ or large_imm@l,%r31,%r31
+ adds %r31,%rx,%rn
+
+ * Unsigned large immediate with logical operations:
+
+ Logical operations (`or, andnot, or, xor') also result in
+ expansions. The pseudo-instruction `or large_imm,%rx,%rn' results
+ in:
+ orh large_imm@h,%rx,%r31
+ or large_imm@l,%r31,%rn
+
+ Similarly for the others, except for `and' which expands to:
+ andnot (-1 - large_imm)@h,%rx,%r31
+ andnot (-1 - large_imm)@l,%r31,%rn

+
+9.17.1 i960 Command-line Options
+--------------------------------
+
+`-ACA | -ACA_A | -ACB | -ACC | -AKA | -AKB | -AKC | -AMC'
+ Select the 80960 architecture. Instructions or features not
+ supported by the selected architecture cause fatal errors.
+
+ `-ACA' is equivalent to `-ACA_A'; `-AKC' is equivalent to `-AMC'.
+ Synonyms are provided for compatibility with other tools.
+
+ If you do not specify any of these options, `as' generates code
+ for any instruction or feature that is supported by _some_ version
+ of the 960 (even if this means mixing architectures!). In
+ principle, `as' attempts to deduce the minimal sufficient
+ processor type if none is specified; depending on the object code
+ format, the processor type may be recorded in the object file. If
+ it is critical that the `as' output match a specific architecture,
+ specify that architecture explicitly.
+
+`-b'
+ Add code to collect information about conditional branches taken,
+ for later optimization using branch prediction bits. (The
+ conditional branch instructions have branch prediction bits in the
+ CA, CB, and CC architectures.) If BR represents a conditional
+ branch instruction, the following represents the code generated by
+ the assembler when `-b' is specified:
+
+ call INCREMENT ROUTINE
+ .word 0 # pre-counter
+ Label: BR
+ call INCREMENT ROUTINE
+ .word 0 # post-counter
+
+ The counter following a branch records the number of times that
+ branch was _not_ taken; the difference between the two counters is
+ the number of times the branch _was_ taken.
+
+ A table of every such `Label' is also generated, so that the
+ external postprocessor `gbr960' (supplied by Intel) can locate all
+ the counters. This table is always labeled `__BRANCH_TABLE__';
+ this is a local symbol to permit collecting statistics for many
+ separate object files. The table is word aligned, and begins with
+ a two-word header. The first word, initialized to 0, is used in
+ maintaining linked lists of branch tables. The second word is a
+ count of the number of entries in the table, which follow
+ immediately: each is a word, pointing to one of the labels
+ illustrated above.
+
+ +------------+------------+------------+ ... +------------+
+ | | | | | |
+ | *NEXT | COUNT: N | *BRLAB 1 | | *BRLAB N |
+ | | | | | |
+ +------------+------------+------------+ ... +------------+
+
+ __BRANCH_TABLE__ layout
+
+ The first word of the header is used to locate multiple branch
+ tables, since each object file may contain one. Normally the links
+ are maintained with a call to an initialization routine, placed at
+ the beginning of each function in the file. The GNU C compiler
+ generates these calls automatically when you give it a `-b' option.
+ For further details, see the documentation of `gbr960'.
+
+`-no-relax'
+ Normally, Compare-and-Branch instructions with targets that require
+ displacements greater than 13 bits (or that have external targets)
+ are replaced with the corresponding compare (or `chkbit') and
+ branch instructions. You can use the `-no-relax' option to
+ specify that `as' should generate errors instead, if the target
+ displacement is larger than 13 bits.
+
+ This option does not affect the Compare-and-Jump instructions; the
+ code emitted for them is _always_ adjusted when necessary
+ (depending on displacement size), regardless of whether you use
+ `-no-relax'.

+
+9.17.3 i960 Machine Directives
+------------------------------
+
+`.bss SYMBOL, LENGTH, ALIGN'
+ Reserve LENGTH bytes in the bss section for a local SYMBOL,
+ aligned to the power of two specified by ALIGN. LENGTH and ALIGN
+ must be positive absolute expressions. This directive differs
+ from `.lcomm' only in that it permits you to specify an alignment.
+ *Note `.lcomm': Lcomm.
+
+`.extended FLONUMS'
+ `.extended' expects zero or more flonums, separated by commas; for
+ each flonum, `.extended' emits an IEEE extended-format (80-bit)
+ floating-point number.
+
+`.leafproc CALL-LAB, BAL-LAB'
+ You can use the `.leafproc' directive in conjunction with the
+ optimized `callj' instruction to enable faster calls of leaf
+ procedures. If a procedure is known to call no other procedures,
+ you may define an entry point that skips procedure prolog code
+ (and that does not depend on system-supplied saved context), and
+ declare it as the BAL-LAB using `.leafproc'. If the procedure
+ also has an entry point that goes through the normal prolog, you
+ can specify that entry point as CALL-LAB.
+
+ A `.leafproc' declaration is meant for use in conjunction with the
+ optimized call instruction `callj'; the directive records the data
+ needed later to choose between converting the `callj' into a `bal'
+ or a `call'.
+
+ CALL-LAB is optional; if only one argument is present, or if the
+ two arguments are identical, the single argument is assumed to be
+ the `bal' entry point.
+
+`.sysproc NAME, INDEX'
+ The `.sysproc' directive defines a name for a system procedure.
+ After you define it using `.sysproc', you can use NAME to refer to
+ the system procedure identified by INDEX when calling procedures
+ with the optimized call instruction `callj'.
+
+ Both arguments are required; INDEX must be between 0 and 31
+ (inclusive).

+9.17.4.1 `callj'
+................
+
+You can write `callj' to have the assembler or the linker determine the
+most appropriate form of subroutine call: `call', `bal', or `calls'.
+If the assembly source contains enough information--a `.leafproc' or
+`.sysproc' directive defining the operand--then `as' translates the
+`callj'; if not, it simply emits the `callj', leaving it for the linker
+to resolve.

+
+9.17.4.2 Compare-and-Branch
+...........................
+
+The 960 architectures provide combined Compare-and-Branch instructions
+that permit you to store the branch target in the lower 13 bits of the
+instruction word itself. However, if you specify a branch target far
+enough away that its address won't fit in 13 bits, the assembler can
+either issue an error, or convert your Compare-and-Branch instruction
+into separate instructions to do the compare and the branch.
+
+ Whether `as' gives an error or expands the instruction depends on
+two choices you can make: whether you use the `-no-relax' option, and
+whether you use a "Compare and Branch" instruction or a "Compare and
+Jump" instruction. The "Jump" instructions are _always_ expanded if
+necessary; the "Branch" instructions are expanded when necessary
+_unless_ you specify `-no-relax'--in which case `as' gives an error
+instead.
+
+ These are the Compare-and-Branch instructions, their "Jump" variants,
+and the instruction pairs they may expand into:

+
+9.18.1 Options
+--------------
+
+`-mconstant-gp'
+ This option instructs the assembler to mark the resulting object
+ file as using the "constant GP" model. With this model, it is
+ assumed that the entire program uses a single global pointer (GP)
+ value. Note that this option does not in any fashion affect the
+ machine code emitted by the assembler. All it does is turn on the
+ EF_IA_64_CONS_GP flag in the ELF file header.
+
+`-mauto-pic'
+ This option instructs the assembler to mark the resulting object
+ file as using the "constant GP without function descriptor" data
+ model. This model is like the "constant GP" model, except that it
+ additionally does away with function descriptors. What this means
+ is that the address of a function refers directly to the
+ function's code entry-point. Normally, such an address would
+ refer to a function descriptor, which contains both the code
+ entry-point and the GP-value needed by the function. Note that
+ this option does not in any fashion affect the machine code
+ emitted by the assembler. All it does is turn on the
+ EF_IA_64_NOFUNCDESC_CONS_GP flag in the ELF file header.
+
+`-milp32'
+`-milp64'
+`-mlp64'
+`-mp64'
+ These options select the data model. The assembler defaults to
+ `-mlp64' (LP64 data model).
+
+`-mle'
+`-mbe'
+ These options select the byte order. The `-mle' option selects
+ little-endian byte order (default) and `-mbe' selects big-endian
+ byte order. Note that IA-64 machine code always uses
+ little-endian byte order.
+
+`-mtune=itanium1'
+`-mtune=itanium2'
+ Tune for a particular IA-64 CPU, ITANIUM1 or ITANIUM2. The default
+ is ITANIUM2.
+
+`-munwind-check=warning'
+`-munwind-check=error'
+ These options control what the assembler will do when performing
+ consistency checks on unwind directives. `-munwind-check=warning'
+ will make the assembler issue a warning when an unwind directive
+ check fails. This is the default. `-munwind-check=error' will
+ make the assembler issue an error when an unwind directive check
+ fails.
+
+`-mhint.b=ok'
+`-mhint.b=warning'
+`-mhint.b=error'
+ These options control what the assembler will do when the `hint.b'
+ instruction is used. `-mhint.b=ok' will make the assembler accept
+ `hint.b'. `-mint.b=warning' will make the assembler issue a
+ warning when `hint.b' is used. `-mhint.b=error' will make the
+ assembler treat `hint.b' as an error, which is the default.
+
+`-x'
+`-xexplicit'
+ These options turn on dependency violation checking.
+
+`-xauto'
+ This option instructs the assembler to automatically insert stop
+ bits where necessary to remove dependency violations. This is the
+ default mode.
+
+`-xnone'
+ This option turns off dependency violation checking.
+
+`-xdebug'
+ This turns on debug output intended to help tracking down bugs in
+ the dependency violation checker.
+
+`-xdebugn'
+ This is a shortcut for -xnone -xdebug.
+
+`-xdebugx'
+ This is a shortcut for -xexplicit -xdebug.

+9.20.2.2 Relocatable Expression Modifiers
+.........................................
+
+The assembler supports several modifiers when using relocatable
+addresses in LM32 instruction operands. The general syntax is the
+following:
+
+ modifier(relocatable-expression)
+
+`lo'
+ This modifier allows you to use bits 0 through 15 of an address
+ expression as 16 bit relocatable expression.
+
+`hi'
+ This modifier allows you to use bits 16 through 23 of an address
+ expression as 16 bit relocatable expression.
+
+ For example
+
+ ori r4, r4, lo(sym+10)
+ orhi r4, r4, hi(sym+10)
+
+`gp'
+ This modified creates a 16-bit relocatable expression that is the
+ offset of the symbol from the global pointer.
+
+ mva r4, gp(sym)
+
+`got'
+ This modifier places a symbol in the GOT and creates a 16-bit
+ relocatable expression that is the offset into the GOT of this
+ symbol.
+
+ lw r4, (gp+got(sym))
+
+`gotofflo16'
+ This modifier allows you to use the bits 0 through 15 of an
+ address which is an offset from the GOT.
+
+`gotoffhi16'
+ This modifier allows you to use the bits 16 through 31 of an
+ address which is an offset from the GOT.
+
+ orhi r4, r4, gotoffhi16(lsym)
+ addi r4, r4, gotofflo16(lsym)

+
+9.21.2.1 Symbolic Operand Modifiers
+...................................
+
+The assembler supports several modifiers when using symbol addresses in
+M32C instruction operands. The general syntax is the following:
+
+ %modifier(symbol)
+
+`%dsp8'
+`%dsp16'
+ These modifiers override the assembler's assumptions about how big
+ a symbol's address is. Normally, when it sees an operand like
+ `sym[a0]' it assumes `sym' may require the widest displacement
+ field (16 bits for `-m16c', 24 bits for `-m32c'). These modifiers
+ tell it to assume the address will fit in an 8 or 16 bit
+ (respectively) unsigned displacement. Note that, of course, if it
+ doesn't actually fit you will get linker errors. Example:
+
+ mov.w %dsp8(sym)[a0],r1
+ mov.b #0,%dsp8(sym)[a0]
+
+`%hi8'
+ This modifier allows you to load bits 16 through 23 of a 24 bit
+ address into an 8 bit register. This is useful with, for example,
+ the M16C `smovf' instruction, which expects a 20 bit address in
+ `r1h' and `a0'. Example:
+
+ mov.b #%hi8(sym),r1h
+ mov.w #%lo16(sym),a0
+ smovf.b
+
+`%lo16'
+ Likewise, this modifier allows you to load bits 0 through 15 of a
+ 24 bit address into a 16 bit register.
+
+`%hi16'
+ This modifier allows you to load bits 16 through 31 of a 32 bit
+ address into a 16 bit register. While the M32C family only has 24
+ bits of address space, it does support addresses in pairs of 16 bit
+ registers (like `a1a0' for the `lde' instruction). This modifier
+ is for loading the upper half in such cases. Example:
+
+ mov.w #%hi16(sym),a1
+ mov.w #%lo16(sym),a0
+ ...
+ lde.w [a1a0],r1

+
+9.21.2.2 Special Characters
+...........................
+
+The presence of a `;' character on a line indicates the start of a
+comment that extends to the end of that line.
+
+ If a `#' appears as the first character of a line, the whole line is
+treated as a comment, but in this case the line can also be a logical
+line number directive (*note Comments::) or a preprocessor control
+command (*note Preprocessing::).
+
+ The `|' character can be used to separate statements on the same
+line.

+
+9.22.1 M32R Options
+-------------------
+
+The Renease M32R version of `as' has a few machine dependent options:
+
+`-m32rx'
+ `as' can assemble code for several different members of the
+ Renesas M32R family. Normally the default is to assemble code for
+ the M32R microprocessor. This option may be used to change the
+ default to the M32RX microprocessor, which adds some more
+ instructions to the basic M32R instruction set, and some
+ additional parameters to some of the original instructions.
+
+`-m32r2'
+ This option changes the target processor to the M32R2
+ microprocessor.
+
+`-m32r'
+ This option can be used to restore the assembler's default
+ behaviour of assembling for the M32R microprocessor. This can be
+ useful if the default has been changed by a previous command line
+ option.
+
+`-little'
+ This option tells the assembler to produce little-endian code and
+ data. The default is dependent upon how the toolchain was
+ configured.
+
+`-EL'
+ This is a synonym for _-little_.
+
+`-big'
+ This option tells the assembler to produce big-endian code and
+ data.
+
+`-EB'
+ This is a synonum for _-big_.
+
+`-KPIC'
+ This option specifies that the output of the assembler should be
+ marked as position-independent code (PIC).
+
+`-parallel'
+ This option tells the assembler to attempts to combine two
+ sequential instructions into a single, parallel instruction, where
+ it is legal to do so.
+
+`-no-parallel'
+ This option disables a previously enabled _-parallel_ option.
+
+`-no-bitinst'
+ This option disables the support for the extended bit-field
+ instructions provided by the M32R2. If this support needs to be
+ re-enabled the _-bitinst_ switch can be used to restore it.
+
+`-O'
+ This option tells the assembler to attempt to optimize the
+ instructions that it produces. This includes filling delay slots
+ and converting sequential instructions into parallel ones. This
+ option implies _-parallel_.
+
+`-warn-explicit-parallel-conflicts'
+ Instructs `as' to produce warning messages when questionable
+ parallel instructions are encountered. This option is enabled by
+ default, but `gcc' disables it when it invokes `as' directly.
+ Questionable instructions are those whose behaviour would be
+ different if they were executed sequentially. For example the
+ code fragment `mv r1, r2 || mv r3, r1' produces a different result
+ from `mv r1, r2 \n mv r3, r1' since the former moves r1 into r3
+ and then r2 into r1, whereas the later moves r2 into r1 and r3.
+
+`-Wp'
+ This is a shorter synonym for the
+ _-warn-explicit-parallel-conflicts_ option.
+
+`-no-warn-explicit-parallel-conflicts'
+ Instructs `as' not to produce warning messages when questionable
+ parallel instructions are encountered.
+
+`-Wnp'
+ This is a shorter synonym for the
+ _-no-warn-explicit-parallel-conflicts_ option.
+
+`-ignore-parallel-conflicts'
+ This option tells the assembler's to stop checking parallel
+ instructions for constraint violations. This ability is provided
+ for hardware vendors testing chip designs and should not be used
+ under normal circumstances.
+
+`-no-ignore-parallel-conflicts'
+ This option restores the assembler's default behaviour of checking
+ parallel instructions to detect constraint violations.
+
+`-Ip'
+ This is a shorter synonym for the _-ignore-parallel-conflicts_
+ option.
+
+`-nIp'
+ This is a shorter synonym for the _-no-ignore-parallel-conflicts_
+ option.
+
+`-warn-unmatched-high'
+ This option tells the assembler to produce a warning message if a
+ `.high' pseudo op is encountered without a matching `.low' pseudo
+ op. The presence of such an unmatched pseudo op usually indicates
+ a programming error.
+
+`-no-warn-unmatched-high'
+ Disables a previously enabled _-warn-unmatched-high_ option.
+
+`-Wuh'
+ This is a shorter synonym for the _-warn-unmatched-high_ option.
+
+`-Wnuh'
+ This is a shorter synonym for the _-no-warn-unmatched-high_ option.

+
+9.22.2 M32R Directives
+----------------------
+
+The Renease M32R version of `as' has a few architecture specific
+directives:
+
+`low EXPRESSION'
+ The `low' directive computes the value of its expression and
+ places the lower 16-bits of the result into the immediate-field of
+ the instruction. For example:
+
+ or3 r0, r0, #low(0x12345678) ; compute r0 = r0 | 0x5678
+ add3, r0, r0, #low(fred) ; compute r0 = r0 + low 16-bits of address of fred
+
+`high EXPRESSION'
+ The `high' directive computes the value of its expression and
+ places the upper 16-bits of the result into the immediate-field of
+ the instruction. For example:
+
+ seth r0, #high(0x12345678) ; compute r0 = 0x12340000
+ seth, r0, #high(fred) ; compute r0 = upper 16-bits of address of fred
+
+`shigh EXPRESSION'
+ The `shigh' directive is very similar to the `high' directive. It
+ also computes the value of its expression and places the upper
+ 16-bits of the result into the immediate-field of the instruction.
+ The difference is that `shigh' also checks to see if the lower
+ 16-bits could be interpreted as a signed number, and if so it
+ assumes that a borrow will occur from the upper-16 bits. To
+ compensate for this the `shigh' directive pre-biases the upper 16
+ bit value by adding one to it. For example:
+
+ For example:
+
+ seth r0, #shigh(0x12345678) ; compute r0 = 0x12340000
+ seth r0, #shigh(0x00008000) ; compute r0 = 0x00010000
+
+ In the second example the lower 16-bits are 0x8000. If these are
+ treated as a signed value and sign extended to 32-bits then the
+ value becomes 0xffff8000. If this value is then added to
+ 0x00010000 then the result is 0x00008000.
+
+ This behaviour is to allow for the different semantics of the
+ `or3' and `add3' instructions. The `or3' instruction treats its
+ 16-bit immediate argument as unsigned whereas the `add3' treats
+ its 16-bit immediate as a signed value. So for example:
+
+ seth r0, #shigh(0x00008000)
+ add3 r0, r0, #low(0x00008000)
+
+ Produces the correct result in r0, whereas:
+
+ seth r0, #shigh(0x00008000)
+ or3 r0, r0, #low(0x00008000)
+
+ Stores 0xffff8000 into r0.
+
+ Note - the `shigh' directive does not know where in the assembly
+ source code the lower 16-bits of the value are going set, so it
+ cannot check to make sure that an `or3' instruction is being used
+ rather than an `add3' instruction. It is up to the programmer to
+ make sure that correct directives are used.
+
+`.m32r'
+ The directive performs a similar thing as the _-m32r_ command line
+ option. It tells the assembler to only accept M32R instructions
+ from now on. An instructions from later M32R architectures are
+ refused.
+
+`.m32rx'
+ The directive performs a similar thing as the _-m32rx_ command
+ line option. It tells the assembler to start accepting the extra
+ instructions in the M32RX ISA as well as the ordinary M32R ISA.
+
+`.m32r2'
+ The directive performs a similar thing as the _-m32r2_ command
+ line option. It tells the assembler to start accepting the extra
+ instructions in the M32R2 ISA as well as the ordinary M32R ISA.
+
+`.little'
+ The directive performs a similar thing as the _-little_ command
+ line option. It tells the assembler to start producing
+ little-endian code and data. This option should be used with care
+ as producing mixed-endian binary files is fraught with danger.
+
+`.big'
+ The directive performs a similar thing as the _-big_ command line
+ option. It tells the assembler to start producing big-endian code
+ and data. This option should be used with care as producing
+ mixed-endian binary files is fraught with danger.

+
+9.22.3 M32R Warnings
+--------------------
+
+There are several warning and error messages that can be produced by
+`as' which are specific to the M32R:
+
+`output of 1st instruction is the same as an input to 2nd instruction - is this intentional ?'
+ This message is only produced if warnings for explicit parallel
+ conflicts have been enabled. It indicates that the assembler has
+ encountered a parallel instruction in which the destination
+ register of the left hand instruction is used as an input register
+ in the right hand instruction. For example in this code fragment
+ `mv r1, r2 || neg r3, r1' register r1 is the destination of the
+ move instruction and the input to the neg instruction.
+
+`output of 2nd instruction is the same as an input to 1st instruction - is this intentional ?'
+ This message is only produced if warnings for explicit parallel
+ conflicts have been enabled. It indicates that the assembler has
+ encountered a parallel instruction in which the destination
+ register of the right hand instruction is used as an input
+ register in the left hand instruction. For example in this code
+ fragment `mv r1, r2 || neg r2, r3' register r2 is the destination
+ of the neg instruction and the input to the move instruction.
+
+`instruction `...' is for the M32RX only'
+ This message is produced when the assembler encounters an
+ instruction which is only supported by the M32Rx processor, and
+ the `-m32rx' command line flag has not been specified to allow
+ assembly of such instructions.
+
+`unknown instruction `...''
+ This message is produced when the assembler encounters an
+ instruction which it does not recognize.
+
+`only the NOP instruction can be issued in parallel on the m32r'
+ This message is produced when the assembler encounters a parallel
+ instruction which does not involve a NOP instruction and the
+ `-m32rx' command line flag has not been specified. Only the M32Rx
+ processor is able to execute two instructions in parallel.
+
+`instruction `...' cannot be executed in parallel.'
+ This message is produced when the assembler encounters a parallel
+ instruction which is made up of one or two instructions which
+ cannot be executed in parallel.
+
+`Instructions share the same execution pipeline'
+ This message is produced when the assembler encounters a parallel
+ instruction whoes components both use the same execution pipeline.
+
+`Instructions write to the same destination register.'
+ This message is produced when the assembler encounters a parallel
+ instruction where both components attempt to modify the same
+ register. For example these code fragments will produce this
+ message: `mv r1, r2 || neg r1, r3' `jl r0 || mv r14, r1' `st r2,
+ @-r1 || mv r1, r3' `mv r1, r2 || ld r0, @r1+' `cmp r1, r2 || addx
+ r3, r4' (Both write to the condition bit)

+
+9.23.1 M680x0 Options
+---------------------
+
+The Motorola 680x0 version of `as' has a few machine dependent options:
+
+`-march=ARCHITECTURE'
+ This option specifies a target architecture. The following
+ architectures are recognized: `68000', `68010', `68020', `68030',
+ `68040', `68060', `cpu32', `isaa', `isaaplus', `isab', `isac' and
+ `cfv4e'.
+
+`-mcpu=CPU'
+ This option specifies a target cpu. When used in conjunction with
+ the `-march' option, the cpu must be within the specified
+ architecture. Also, the generic features of the architecture are
+ used for instruction generation, rather than those of the specific
+ chip.
+
+`-m[no-]68851'
+`-m[no-]68881'
+`-m[no-]div'
+`-m[no-]usp'
+`-m[no-]float'
+`-m[no-]mac'
+`-m[no-]emac'
+ Enable or disable various architecture specific features. If a
+ chip or architecture by default supports an option (for instance
+ `-march=isaaplus' includes the `-mdiv' option), explicitly
+ disabling the option will override the default.
+
+`-l'
+ You can use the `-l' option to shorten the size of references to
+ undefined symbols. If you do not use the `-l' option, references
+ to undefined symbols are wide enough for a full `long' (32 bits).
+ (Since `as' cannot know where these symbols end up, `as' can only
+ allocate space for the linker to fill in later. Since `as' does
+ not know how far away these symbols are, it allocates as much
+ space as it can.) If you use this option, the references are only
+ one word wide (16 bits). This may be useful if you want the
+ object file to be as small as possible, and you know that the
+ relevant symbols are always less than 17 bits away.
+
+`--register-prefix-optional'
+ For some configurations, especially those where the compiler
+ normally does not prepend an underscore to the names of user
+ variables, the assembler requires a `%' before any use of a
+ register name. This is intended to let the assembler distinguish
+ between C variables and functions named `a0' through `a7', and so
+ on. The `%' is always accepted, but is not required for certain
+ configurations, notably `sun3'. The `--register-prefix-optional'
+ option may be used to permit omitting the `%' even for
+ configurations for which it is normally required. If this is
+ done, it will generally be impossible to refer to C variables and
+ functions with the same names as register names.
+
+`--bitwise-or'
+ Normally the character `|' is treated as a comment character, which
+ means that it can not be used in expressions. The `--bitwise-or'
+ option turns `|' into a normal character. In this mode, you must
+ either use C style comments, or start comments with a `#' character
+ at the beginning of a line.
+
+`--base-size-default-16 --base-size-default-32'
+ If you use an addressing mode with a base register without
+ specifying the size, `as' will normally use the full 32 bit value.
+ For example, the addressing mode `%a0@(%d0)' is equivalent to
+ `%a0@(%d0:l)'. You may use the `--base-size-default-16' option to
+ tell `as' to default to using the 16 bit value. In this case,
+ `%a0@(%d0)' is equivalent to `%a0@(%d0:w)'. You may use the
+ `--base-size-default-32' option to restore the default behaviour.
+
+`--disp-size-default-16 --disp-size-default-32'
+ If you use an addressing mode with a displacement, and the value
+ of the displacement is not known, `as' will normally assume that
+ the value is 32 bits. For example, if the symbol `disp' has not
+ been defined, `as' will assemble the addressing mode
+ `%a0@(disp,%d0)' as though `disp' is a 32 bit value. You may use
+ the `--disp-size-default-16' option to tell `as' to instead assume
+ that the displacement is 16 bits. In this case, `as' will
+ assemble `%a0@(disp,%d0)' as though `disp' is a 16 bit value. You
+ may use the `--disp-size-default-32' option to restore the default
+ behaviour.
+
+`--pcrel'
+ Always keep branches PC-relative. In the M680x0 architecture all
+ branches are defined as PC-relative. However, on some processors
+ they are limited to word displacements maximum. When `as' needs a
+ long branch that is not available, it normally emits an absolute
+ jump instead. This option disables this substitution. When this
+ option is given and no long branches are available, only word
+ branches will be emitted. An error message will be generated if a
+ word branch cannot reach its target. This option has no effect on
+ 68020 and other processors that have long branches. *note Branch
+ Improvement: M68K-Branch.
+
+`-m68000'
+ `as' can assemble code for several different members of the
+ Motorola 680x0 family. The default depends upon how `as' was
+ configured when it was built; normally, the default is to assemble
+ code for the 68020 microprocessor. The following options may be
+ used to change the default. These options control which
+ instructions and addressing modes are permitted. The members of
+ the 680x0 family are very similar. For detailed information about
+ the differences, see the Motorola manuals.
+
+ `-m68000'
+ `-m68ec000'

+9.23.2 Syntax
+-------------
+
+This syntax for the Motorola 680x0 was developed at MIT.
+
+ The 680x0 version of `as' uses instructions names and syntax
+compatible with the Sun assembler. Intervening periods are ignored;
+for example, `movl' is equivalent to `mov.l'.
+
+ In the following table APC stands for any of the address registers
+(`%a0' through `%a7'), the program counter (`%pc'), the zero-address
+relative to the program counter (`%zpc'), a suppressed address register
+(`%za0' through `%za7'), or it may be omitted entirely. The use of
+SIZE means one of `w' or `l', and it may be omitted, along with the
+leading colon, unless a scale is also specified. The use of SCALE
+means one of `1', `2', `4', or `8', and it may always be omitted along
+with the leading colon.
+
+ The following addressing modes are understood:
+"Immediate"
+ `#NUMBER'
+
+"Data Register"
+ `%d0' through `%d7'
+
+"Address Register"
+ `%a0' through `%a7'
+ `%a7' is also known as `%sp', i.e., the Stack Pointer. `%a6' is
+ also known as `%fp', the Frame Pointer.
+
+"Address Register Indirect"
+ `%a0@' through `%a7@'
+
+"Address Register Postincrement"
+ `%a0@+' through `%a7@+'
+
+"Address Register Predecrement"
+ `%a0@-' through `%a7@-'
+
+"Indirect Plus Offset"
+ `APC@(NUMBER)'
+
+"Index"
+ `APC@(NUMBER,REGISTER:SIZE:SCALE)'
+
+ The NUMBER may be omitted.
+
+"Postindex"
+ `APC@(NUMBER)@(ONUMBER,REGISTER:SIZE:SCALE)'
+
+ The ONUMBER or the REGISTER, but not both, may be omitted.
+
+"Preindex"
+ `APC@(NUMBER,REGISTER:SIZE:SCALE)@(ONUMBER)'
+
+ The NUMBER may be omitted. Omitting the REGISTER produces the
+ Postindex addressing mode.
+
+"Absolute"
+ `SYMBOL', or `DIGITS', optionally followed by `:b', `:w', or `:l'.

+9.23.3 Motorola Syntax
+----------------------
+
+The standard Motorola syntax for this chip differs from the syntax
+already discussed (*note Syntax: M68K-Syntax.). `as' can accept
+Motorola syntax for operands, even if MIT syntax is used for other
+operands in the same instruction. The two kinds of syntax are fully
+compatible.
+
+ In the following table APC stands for any of the address registers
+(`%a0' through `%a7'), the program counter (`%pc'), the zero-address
+relative to the program counter (`%zpc'), or a suppressed address
+register (`%za0' through `%za7'). The use of SIZE means one of `w' or
+`l', and it may always be omitted along with the leading dot. The use
+of SCALE means one of `1', `2', `4', or `8', and it may always be
+omitted along with the leading asterisk.
+
+ The following additional addressing modes are understood:
+
+"Address Register Indirect"
+ `(%a0)' through `(%a7)'
+ `%a7' is also known as `%sp', i.e., the Stack Pointer. `%a6' is
+ also known as `%fp', the Frame Pointer.
+
+"Address Register Postincrement"
+ `(%a0)+' through `(%a7)+'
+
+"Address Register Predecrement"
+ `-(%a0)' through `-(%a7)'
+
+"Indirect Plus Offset"
+ `NUMBER(%A0)' through `NUMBER(%A7)', or `NUMBER(%PC)'.
+
+ The NUMBER may also appear within the parentheses, as in
+ `(NUMBER,%A0)'. When used with the PC, the NUMBER may be omitted
+ (with an address register, omitting the NUMBER produces Address
+ Register Indirect mode).
+
+"Index"
+ `NUMBER(APC,REGISTER.SIZE*SCALE)'
+
+ The NUMBER may be omitted, or it may appear within the
+ parentheses. The APC may be omitted. The REGISTER and the APC
+ may appear in either order. If both APC and REGISTER are address
+ registers, and the SIZE and SCALE are omitted, then the first
+ register is taken as the base register, and the second as the
+ index register.
+
+"Postindex"
+ `([NUMBER,APC],REGISTER.SIZE*SCALE,ONUMBER)'
+
+ The ONUMBER, or the REGISTER, or both, may be omitted. Either the
+ NUMBER or the APC may be omitted, but not both.
+
+"Preindex"
+ `([NUMBER,APC,REGISTER.SIZE*SCALE],ONUMBER)'
+
+ The NUMBER, or the APC, or the REGISTER, or any two of them, may
+ be omitted. The ONUMBER may be omitted. The REGISTER and the APC
+ may appear in either order. If both APC and REGISTER are address
+ registers, and the SIZE and SCALE are omitted, then the first
+ register is taken as the base register, and the second as the
+ index register.

+
+9.23.5 680x0 Machine Directives
+-------------------------------
+
+In order to be compatible with the Sun assembler the 680x0 assembler
+understands the following directives.
+
+`.data1'
+ This directive is identical to a `.data 1' directive.
+
+`.data2'
+ This directive is identical to a `.data 2' directive.
+
+`.even'
+ This directive is a special case of the `.align' directive; it
+ aligns the output to an even byte boundary.
+
+`.skip'
+ This directive is identical to a `.space' directive.
+
+`.arch NAME'
+ Select the target architecture and extension features. Valid
+ values for NAME are the same as for the `-march' command line
+ option. This directive cannot be specified after any instructions
+ have been assembled. If it is given multiple times, or in
+ conjunction with the `-march' option, all uses must be for the
+ same architecture and extension set.
+
+`.cpu NAME'
+ Select the target cpu. Valid valuse for NAME are the same as for
+ the `-mcpu' command line option. This directive cannot be
+ specified after any instructions have been assembled. If it is
+ given multiple times, or in conjunction with the `-mopt' option,
+ all uses must be for the same cpu.

+
+9.23.6.1 Branch Improvement
+...........................
+
+Certain pseudo opcodes are permitted for branch instructions. They
+expand to the shortest branch instruction that reach the target.
+Generally these mnemonics are made by substituting `j' for `b' at the
+start of a Motorola mnemonic.
+
+ The following table summarizes the pseudo-operations. A `*' flags
+cases that are more fully described after the table:
+
+ Displacement
+ +------------------------------------------------------------
+ | 68020 68000/10, not PC-relative OK
+ Pseudo-Op |BYTE WORD LONG ABSOLUTE LONG JUMP **
+ +------------------------------------------------------------
+ jbsr |bsrs bsrw bsrl jsr
+ jra |bras braw bral jmp
+ * jXX |bXXs bXXw bXXl bNXs;jmp
+ * dbXX | N/A dbXXw dbXX;bras;bral dbXX;bras;jmp
+ fjXX | N/A fbXXw fbXXl N/A
+
+ XX: condition
+ NX: negative of condition XX
+ `*'--see full description below
+ `**'--this expansion mode is disallowed by `--pcrel'
+
+`jbsr'
+`jra'
+ These are the simplest jump pseudo-operations; they always map to
+ one particular machine instruction, depending on the displacement
+ to the branch target. This instruction will be a byte or word
+ branch is that is sufficient. Otherwise, a long branch will be
+ emitted if available. If no long branches are available and the
+ `--pcrel' option is not given, an absolute long jump will be
+ emitted instead. If no long branches are available, the `--pcrel'
+ option is given, and a word branch cannot reach the target, an
+ error message is generated.
+
+ In addition to standard branch operands, `as' allows these
+ pseudo-operations to have all operands that are allowed for jsr
+ and jmp, substituting these instructions if the operand given is
+ not valid for a branch instruction.
+
+`jXX'
+ Here, `jXX' stands for an entire family of pseudo-operations,
+ where XX is a conditional branch or condition-code test. The full
+ list of pseudo-ops in this family is:
+ jhi jls jcc jcs jne jeq jvc
+ jvs jpl jmi jge jlt jgt jle
+
+ Usually, each of these pseudo-operations expands to a single branch
+ instruction. However, if a word branch is not sufficient, no long
+ branches are available, and the `--pcrel' option is not given, `as'
+ issues a longer code fragment in terms of NX, the opposite
+ condition to XX. For example, under these conditions:
+ jXX foo
+ gives
+ bNXs oof
+ jmp foo
+ oof:
+
+`dbXX'
+ The full family of pseudo-operations covered here is
+ dbhi dbls dbcc dbcs dbne dbeq dbvc
+ dbvs dbpl dbmi dbge dblt dbgt dble
+ dbf dbra dbt
+
+ Motorola `dbXX' instructions allow word displacements only. When
+ a word displacement is sufficient, each of these pseudo-operations
+ expands to the corresponding Motorola instruction. When a word
+ displacement is not sufficient and long branches are available,
+ when the source reads `dbXX foo', `as' emits
+ dbXX oo1
+ bras oo2
+ oo1:bral foo
+ oo2:
+
+ If, however, long branches are not available and the `--pcrel'
+ option is not given, `as' emits
+ dbXX oo1
+ bras oo2
+ oo1:jmp foo
+ oo2:
+
+`fjXX'
+ This family includes
+ fjne fjeq fjge fjlt fjgt fjle fjf
+ fjt fjgl fjgle fjnge fjngl fjngle fjngt
+ fjnle fjnlt fjoge fjogl fjogt fjole fjolt
+ fjor fjseq fjsf fjsne fjst fjueq fjuge
+ fjugt fjule fjult fjun
+
+ Each of these pseudo-operations always expands to a single Motorola
+ coprocessor branch instruction, word or long. All Motorola
+ coprocessor branch instructions allow both word and long
+ displacements.

+
+9.23.6.2 Special Characters
+...........................
+
+Line comments are introduced by the `|' character appearing anywhere on
+a line, unless the `--bitwise-or' command line option has been
+specified.
+
+ An asterisk (`*') as the first character on a line marks the start
+of a line comment as well.
+
+ A hash character (`#') as the first character on a line also marks
+the start of a line comment, but in this case it could also be a
+logical line number directive (*note Comments::) or a preprocessor
+control command (*note Preprocessing::). If the hash character appears
+elsewhere on a line it is used to introduce an immediate value. (This
+is for compatibility with Sun's assembler).
+
+ Multiple statements on the same line can appear if they are separated
+by the `;' character.

+
+9.24.1 M68HC11 and M68HC12 Options
+----------------------------------
+
+The Motorola 68HC11 and 68HC12 version of `as' have a few machine
+dependent options.
+
+`-m68hc11'
+ This option switches the assembler into the M68HC11 mode. In this
+ mode, the assembler only accepts 68HC11 operands and mnemonics. It
+ produces code for the 68HC11.
+
+`-m68hc12'
+ This option switches the assembler into the M68HC12 mode. In this
+ mode, the assembler also accepts 68HC12 operands and mnemonics. It
+ produces code for the 68HC12. A few 68HC11 instructions are
+ replaced by some 68HC12 instructions as recommended by Motorola
+ specifications.
+
+`-m68hcs12'
+ This option switches the assembler into the M68HCS12 mode. This
+ mode is similar to `-m68hc12' but specifies to assemble for the
+ 68HCS12 series. The only difference is on the assembling of the
+ `movb' and `movw' instruction when a PC-relative operand is used.
+
+`-mm9s12x'
+ This option switches the assembler into the M9S12X mode. This
+ mode is similar to `-m68hc12' but specifies to assemble for the
+ S12X series which is a superset of the HCS12.
+
+`-mm9s12xg'
+ This option switches the assembler into the XGATE mode for the RISC
+ co-processor featured on some S12X-family chips.
+
+`--xgate-ramoffset'
+ This option instructs the linker to offset RAM addresses from S12X
+ address space into XGATE address space.
+
+`-mshort'
+ This option controls the ABI and indicates to use a 16-bit integer
+ ABI. It has no effect on the assembled instructions. This is the
+ default.
+
+`-mlong'
+ This option controls the ABI and indicates to use a 32-bit integer
+ ABI.
+
+`-mshort-double'
+ This option controls the ABI and indicates to use a 32-bit float
+ ABI. This is the default.
+
+`-mlong-double'
+ This option controls the ABI and indicates to use a 64-bit float
+ ABI.
+
+`--strict-direct-mode'
+ You can use the `--strict-direct-mode' option to disable the
+ automatic translation of direct page mode addressing into extended
+ mode when the instruction does not support direct mode. For
+ example, the `clr' instruction does not support direct page mode
+ addressing. When it is used with the direct page mode, `as' will
+ ignore it and generate an absolute addressing. This option
+ prevents `as' from doing this, and the wrong usage of the direct
+ page mode will raise an error.
+
+`--short-branches'
+ The `--short-branches' option turns off the translation of
+ relative branches into absolute branches when the branch offset is
+ out of range. By default `as' transforms the relative branch
+ (`bsr', `bgt', `bge', `beq', `bne', `ble', `blt', `bhi', `bcc',
+ `bls', `bcs', `bmi', `bvs', `bvs', `bra') into an absolute branch
+ when the offset is out of the -128 .. 127 range. In that case,
+ the `bsr' instruction is translated into a `jsr', the `bra'
+ instruction is translated into a `jmp' and the conditional
+ branches instructions are inverted and followed by a `jmp'. This
+ option disables these translations and `as' will generate an error
+ if a relative branch is out of range. This option does not affect
+ the optimization associated to the `jbra', `jbsr' and `jbXX'
+ pseudo opcodes.
+
+`--force-long-branches'
+ The `--force-long-branches' option forces the translation of
+ relative branches into absolute branches. This option does not
+ affect the optimization associated to the `jbra', `jbsr' and
+ `jbXX' pseudo opcodes.
+
+`--print-insn-syntax'
+ You can use the `--print-insn-syntax' option to obtain the syntax
+ description of the instruction when an error is detected.
+
+`--print-opcodes'
+ The `--print-opcodes' option prints the list of all the
+ instructions with their syntax. The first item of each line
+ represents the instruction name and the rest of the line indicates
+ the possible operands for that instruction. The list is printed in
+ alphabetical order. Once the list is printed `as' exits.
+
+`--generate-example'
+ The `--generate-example' option is similar to `--print-opcodes'
+ but it generates an example for each instruction instead.
+

+
+9.24.2 Syntax
+-------------
+
+In the M68HC11 syntax, the instruction name comes first and it may be
+followed by one or several operands (up to three). Operands are
+separated by comma (`,'). In the normal mode, `as' will complain if too
+many operands are specified for a given instruction. In the MRI mode
+(turned on with `-M' option), it will treat them as comments. Example:
+
+ inx
+ lda #23
+ bset 2,x #4
+ brclr *bot #8 foo
+
+ The presence of a `;' character or a `!' character anywhere on a
+line indicates the start of a comment that extends to the end of that
+line.
+
+ A `*' or a `#' character at the start of a line also introduces a
+line comment, but these characters do not work elsewhere on the line.
+If the first character of the line is a `#' then as well as starting a
+comment, the line could also be logical line number directive (*note
+Comments::) or a preprocessor control command (*note Preprocessing::).
+
+ The M68HC11 assembler does not currently support a line separator
+character.
+
+ The following addressing modes are understood for 68HC11 and 68HC12:
+"Immediate"
+ `#NUMBER'
+
+"Address Register"
+ `NUMBER,X', `NUMBER,Y'
+
+ The NUMBER may be omitted in which case 0 is assumed.
+
+"Direct Addressing mode"
+ `*SYMBOL', or `*DIGITS'
+
+"Absolute"
+ `SYMBOL', or `DIGITS'
+
+ The M68HC12 has other more complex addressing modes. All of them are
+supported and they are represented below:
+
+"Constant Offset Indexed Addressing Mode"
+ `NUMBER,REG'
+
+ The NUMBER may be omitted in which case 0 is assumed. The
+ register can be either `X', `Y', `SP' or `PC'. The assembler will
+ use the smaller post-byte definition according to the constant
+ value (5-bit constant offset, 9-bit constant offset or 16-bit
+ constant offset). If the constant is not known by the assembler
+ it will use the 16-bit constant offset post-byte and the value
+ will be resolved at link time.
+
+"Offset Indexed Indirect"
+ `[NUMBER,REG]'
+
+ The register can be either `X', `Y', `SP' or `PC'.
+
+"Auto Pre-Increment/Pre-Decrement/Post-Increment/Post-Decrement"
+ `NUMBER,-REG' `NUMBER,+REG' `NUMBER,REG-' `NUMBER,REG+'
+
+ The number must be in the range `-8'..`+8' and must not be 0. The
+ register can be either `X', `Y', `SP' or `PC'.
+
+"Accumulator Offset"
+ `ACC,REG'
+
+ The accumulator register can be either `A', `B' or `D'. The
+ register can be either `X', `Y', `SP' or `PC'.
+
+"Accumulator D offset indexed-indirect"
+ `[D,REG]'
+
+ The register can be either `X', `Y', `SP' or `PC'.
+
+
+ For example:
+
+ ldab 1024,sp
+ ldd [10,x]
+ orab 3,+x
+ stab -2,y-
+ ldx a,pc
+ sty [d,sp]

+
+9.24.3 Symbolic Operand Modifiers
+---------------------------------
+
+The assembler supports several modifiers when using symbol addresses in
+68HC11 and 68HC12 instruction operands. The general syntax is the
+following:
+
+ %modifier(symbol)
+
+`%addr'
+ This modifier indicates to the assembler and linker to use the
+ 16-bit physical address corresponding to the symbol. This is
+ intended to be used on memory window systems to map a symbol in
+ the memory bank window. If the symbol is in a memory expansion
+ part, the physical address corresponds to the symbol address
+ within the memory bank window. If the symbol is not in a memory
+ expansion part, this is the symbol address (using or not using the
+ %addr modifier has no effect in that case).
+
+`%page'
+ This modifier indicates to use the memory page number corresponding
+ to the symbol. If the symbol is in a memory expansion part, its
+ page number is computed by the linker as a number used to map the
+ page containing the symbol in the memory bank window. If the
+ symbol is not in a memory expansion part, the page number is 0.
+
+`%hi'
+ This modifier indicates to use the 8-bit high part of the physical
+ address of the symbol.
+
+`%lo'
+ This modifier indicates to use the 8-bit low part of the physical
+ address of the symbol.
+
+
+ For example a 68HC12 call to a function `foo_example' stored in
+memory expansion part could be written as follows:
+
+ call %addr(foo_example),%page(foo_example)
+
+ and this is equivalent to
+
+ call foo_example
+
+ And for 68HC11 it could be written as follows:
+
+ ldab #%page(foo_example)
+ stab _page_switch
+ jsr %addr(foo_example)
+

+
+9.24.4 Assembler Directives
+---------------------------
+
+The 68HC11 and 68HC12 version of `as' have the following specific
+assembler directives:
+
+`.relax'
+ The relax directive is used by the `GNU Compiler' to emit a
+ specific relocation to mark a group of instructions for linker
+ relaxation. The sequence of instructions within the group must be
+ known to the linker so that relaxation can be performed.
+
+`.mode [mshort|mlong|mshort-double|mlong-double]'
+ This directive specifies the ABI. It overrides the `-mshort',
+ `-mlong', `-mshort-double' and `-mlong-double' options.
+
+`.far SYMBOL'
+ This directive marks the symbol as a `far' symbol meaning that it
+ uses a `call/rtc' calling convention as opposed to `jsr/rts'.
+ During a final link, the linker will identify references to the
+ `far' symbol and will verify the proper calling convention.
+
+`.interrupt SYMBOL'
+ This directive marks the symbol as an interrupt entry point. This
+ information is then used by the debugger to correctly unwind the
+ frame across interrupts.
+
+`.xrefb SYMBOL'
+ This directive is defined for compatibility with the
+ `Specification for Motorola 8 and 16-Bit Assembly Language Input
+ Standard' and is ignored.
+

+9.24.6.1 Branch Improvement
+...........................
+
+Certain pseudo opcodes are permitted for branch instructions. They
+expand to the shortest branch instruction that reach the target.
+Generally these mnemonics are made by prepending `j' to the start of
+Motorola mnemonic. These pseudo opcodes are not affected by the
+`--short-branches' or `--force-long-branches' options.
+
+ The following table summarizes the pseudo-operations.
+
+ Displacement Width
+ +-------------------------------------------------------------+
+ | Options |
+ | --short-branches --force-long-branches |
+ +--------------------------+----------------------------------+
+ Op |BYTE WORD | BYTE WORD |
+ +--------------------------+----------------------------------+
+ bsr | bsr <pc-rel> <error> | jsr <abs> |
+ bra | bra <pc-rel> <error> | jmp <abs> |
+ jbsr | bsr <pc-rel> jsr <abs> | bsr <pc-rel> jsr <abs> |
+ jbra | bra <pc-rel> jmp <abs> | bra <pc-rel> jmp <abs> |
+ bXX | bXX <pc-rel> <error> | bNX +3; jmp <abs> |
+ jbXX | bXX <pc-rel> bNX +3; | bXX <pc-rel> bNX +3; jmp <abs> |
+ | jmp <abs> | |
+ +--------------------------+----------------------------------+
+ XX: condition
+ NX: negative of condition XX
+
+`jbsr'
+`jbra'
+ These are the simplest jump pseudo-operations; they always map to
+ one particular machine instruction, depending on the displacement
+ to the branch target.
+
+`jbXX'
+ Here, `jbXX' stands for an entire family of pseudo-operations,
+ where XX is a conditional branch or condition-code test. The full
+ list of pseudo-ops in this family is:
+ jbcc jbeq jbge jbgt jbhi jbvs jbpl jblo
+ jbcs jbne jblt jble jbls jbvc jbmi
+
+ For the cases of non-PC relative displacements and long
+ displacements, `as' issues a longer code fragment in terms of NX,
+ the opposite condition to XX. For example, for the non-PC
+ relative case:
+ jbXX foo
+ gives
+ bNXs oof
+ jmp foo
+ oof:

+9.27.1 Assembler options
+------------------------
+
+The MIPS configurations of GNU `as' support these special options:
+
+`-G NUM'
+ Set the "small data" limit to N bytes. The default limit is 8
+ bytes. *Note Controlling the use of small data accesses: MIPS
+ Small Data.
+
+`-EB'
+`-EL'
+ Any MIPS configuration of `as' can select big-endian or
+ little-endian output at run time (unlike the other GNU development
+ tools, which must be configured for one or the other). Use `-EB'
+ to select big-endian output, and `-EL' for little-endian.
+
+`-KPIC'
+ Generate SVR4-style PIC. This option tells the assembler to
+ generate SVR4-style position-independent macro expansions. It
+ also tells the assembler to mark the output file as PIC.
+
+`-mvxworks-pic'
+ Generate VxWorks PIC. This option tells the assembler to generate
+ VxWorks-style position-independent macro expansions.
+
+`-mips1'
+`-mips2'
+`-mips3'
+`-mips4'
+`-mips5'
+`-mips32'
+`-mips32r2'
+`-mips32r3'
+`-mips32r5'
+`-mips32r6'
+`-mips64'
+`-mips64r2'
+`-mips64r3'
+`-mips64r5'
+`-mips64r6'
+ Generate code for a particular MIPS Instruction Set Architecture
+ level. `-mips1' corresponds to the R2000 and R3000 processors,
+ `-mips2' to the R6000 processor, `-mips3' to the R4000 processor,
+ and `-mips4' to the R8000 and R10000 processors. `-mips5',
+ `-mips32', `-mips32r2', `-mips32r3', `-mips32r5', `-mips32r6',
+ `-mips64', `-mips64r2', `-mips64r3', `-mips64r5', and `-mips64r6'
+ correspond to generic MIPS V, MIPS32, MIPS32 Release 2, MIPS32
+ Release 3, MIPS32 Release 5, MIPS32 Release 6, MIPS64, and MIPS64
+ Release 2, MIPS64 Release 3, MIPS64 Release 5, and MIPS64 Release
+ 6 ISA processors, respectively. You can also switch instruction
+ sets during the assembly; see *Note Directives to override the ISA
+ level: MIPS ISA.
+
+`-mgp32'
+`-mfp32'
+ Some macros have different expansions for 32-bit and 64-bit
+ registers. The register sizes are normally inferred from the ISA
+ and ABI, but these flags force a certain group of registers to be
+ treated as 32 bits wide at all times. `-mgp32' controls the size
+ of general-purpose registers and `-mfp32' controls the size of
+ floating-point registers.
+
+ The `.set gp=32' and `.set fp=32' directives allow the size of
+ registers to be changed for parts of an object. The default value
+ is restored by `.set gp=default' and `.set fp=default'.
+
+ On some MIPS variants there is a 32-bit mode flag; when this flag
+ is set, 64-bit instructions generate a trap. Also, some 32-bit
+ OSes only save the 32-bit registers on a context switch, so it is
+ essential never to use the 64-bit registers.
+
+`-mgp64'
+`-mfp64'
+ Assume that 64-bit registers are available. This is provided in
+ the interests of symmetry with `-mgp32' and `-mfp32'.
+
+ The `.set gp=64' and `.set fp=64' directives allow the size of
+ registers to be changed for parts of an object. The default value
+ is restored by `.set gp=default' and `.set fp=default'.
+
+`-mfpxx'
+ Make no assumptions about whether 32-bit or 64-bit floating-point
+ registers are available. This is provided to support having modules
+ compatible with either `-mfp32' or `-mfp64'. This option can only
+ be used with MIPS II and above.
+
+ The `.set fp=xx' directive allows a part of an object to be marked
+ as not making assumptions about 32-bit or 64-bit FP registers. The
+ default value is restored by `.set fp=default'.
+
+`-modd-spreg'
+`-mno-odd-spreg'
+ Enable use of floating-point operations on odd-numbered
+ single-precision registers when supported by the ISA. `-mfpxx'
+ implies `-mno-odd-spreg', otherwise the default is `-modd-spreg'
+
+`-mips16'
+`-no-mips16'
+ Generate code for the MIPS 16 processor. This is equivalent to
+ putting `.set mips16' at the start of the assembly file.
+ `-no-mips16' turns off this option.
+
+`-mmicromips'
+`-mno-micromips'
+ Generate code for the microMIPS processor. This is equivalent to
+ putting `.set micromips' at the start of the assembly file.
+ `-mno-micromips' turns off this option. This is equivalent to
+ putting `.set nomicromips' at the start of the assembly file.
+
+`-msmartmips'
+`-mno-smartmips'
+ Enables the SmartMIPS extensions to the MIPS32 instruction set,
+ which provides a number of new instructions which target smartcard
+ and cryptographic applications. This is equivalent to putting
+ `.set smartmips' at the start of the assembly file.
+ `-mno-smartmips' turns off this option.
+
+`-mips3d'
+`-no-mips3d'
+ Generate code for the MIPS-3D Application Specific Extension.
+ This tells the assembler to accept MIPS-3D instructions.
+ `-no-mips3d' turns off this option.
+
+`-mdmx'
+`-no-mdmx'
+ Generate code for the MDMX Application Specific Extension. This
+ tells the assembler to accept MDMX instructions. `-no-mdmx' turns
+ off this option.
+
+`-mdsp'
+`-mno-dsp'
+ Generate code for the DSP Release 1 Application Specific Extension.
+ This tells the assembler to accept DSP Release 1 instructions.
+ `-mno-dsp' turns off this option.
+
+`-mdspr2'
+`-mno-dspr2'
+ Generate code for the DSP Release 2 Application Specific Extension.
+ This option implies -mdsp. This tells the assembler to accept DSP
+ Release 2 instructions. `-mno-dspr2' turns off this option.
+
+`-mmt'
+`-mno-mt'
+ Generate code for the MT Application Specific Extension. This
+ tells the assembler to accept MT instructions. `-mno-mt' turns
+ off this option.
+
+`-mmcu'
+`-mno-mcu'
+ Generate code for the MCU Application Specific Extension. This
+ tells the assembler to accept MCU instructions. `-mno-mcu' turns
+ off this option.
+
+`-mmsa'
+`-mno-msa'
+ Generate code for the MIPS SIMD Architecture Extension. This
+ tells the assembler to accept MSA instructions. `-mno-msa' turns
+ off this option.
+
+`-mxpa'
+`-mno-xpa'
+ Generate code for the MIPS eXtended Physical Address (XPA)
+ Extension. This tells the assembler to accept XPA instructions.
+ `-mno-xpa' turns off this option.
+
+`-mvirt'
+`-mno-virt'
+ Generate code for the Virtualization Application Specific
+ Extension. This tells the assembler to accept Virtualization
+ instructions. `-mno-virt' turns off this option.
+
+`-minsn32'
+`-mno-insn32'
+ Only use 32-bit instruction encodings when generating code for the
+ microMIPS processor. This option inhibits the use of any 16-bit
+ instructions. This is equivalent to putting `.set insn32' at the
+ start of the assembly file. `-mno-insn32' turns off this option.
+ This is equivalent to putting `.set noinsn32' at the start of the
+ assembly file. By default `-mno-insn32' is selected, allowing all
+ instructions to be used.
+
+`-mfix7000'
+`-mno-fix7000'
+ Cause nops to be inserted if the read of the destination register
+ of an mfhi or mflo instruction occurs in the following two
+ instructions.
+
+`-mfix-rm7000'
+`-mno-fix-rm7000'
+ Cause nops to be inserted if a dmult or dmultu instruction is
+ followed by a load instruction.
+
+`-mfix-loongson2f-jump'
+`-mno-fix-loongson2f-jump'
+ Eliminate instruction fetch from outside 256M region to work
+ around the Loongson2F `jump' instructions. Without it, under
+ extreme cases, the kernel may crash. The issue has been solved in
+ latest processor batches, but this fix has no side effect to them.
+
+`-mfix-loongson2f-nop'
+`-mno-fix-loongson2f-nop'
+ Replace nops by `or at,at,zero' to work around the Loongson2F
+ `nop' errata. Without it, under extreme cases, the CPU might
+ deadlock. The issue has been solved in later Loongson2F batches,
+ but this fix has no side effect to them.
+
+`-mfix-vr4120'
+`-mno-fix-vr4120'
+ Insert nops to work around certain VR4120 errata. This option is
+ intended to be used on GCC-generated code: it is not designed to
+ catch all problems in hand-written assembler code.
+
+`-mfix-vr4130'
+`-mno-fix-vr4130'
+ Insert nops to work around the VR4130 `mflo'/`mfhi' errata.
+
+`-mfix-24k'
+`-mno-fix-24k'
+ Insert nops to work around the 24K `eret'/`deret' errata.
+
+`-mfix-cn63xxp1'
+`-mno-fix-cn63xxp1'
+ Replace `pref' hints 0 - 4 and 6 - 24 with hint 28 to work around
+ certain CN63XXP1 errata.
+
+`-m4010'
+`-no-m4010'
+ Generate code for the LSI R4010 chip. This tells the assembler to
+ accept the R4010-specific instructions (`addciu', `ffc', etc.),
+ and to not schedule `nop' instructions around accesses to the `HI'
+ and `LO' registers. `-no-m4010' turns off this option.
+
+`-m4650'
+`-no-m4650'
+ Generate code for the MIPS R4650 chip. This tells the assembler
+ to accept the `mad' and `madu' instruction, and to not schedule
+ `nop' instructions around accesses to the `HI' and `LO' registers.
+ `-no-m4650' turns off this option.
+
+`-m3900'
+`-no-m3900'
+`-m4100'
+`-no-m4100'
+ For each option `-mNNNN', generate code for the MIPS RNNNN chip.
+ This tells the assembler to accept instructions specific to that
+ chip, and to schedule for that chip's hazards.
+
+`-march=CPU'
+ Generate code for a particular MIPS CPU. It is exactly equivalent
+ to `-mCPU', except that there are more value of CPU understood.
+ Valid CPU value are:
+
+ 2000, 3000, 3900, 4000, 4010, 4100, 4111, vr4120, vr4130,
+ vr4181, 4300, 4400, 4600, 4650, 5000, rm5200, rm5230, rm5231,
+ rm5261, rm5721, vr5400, vr5500, 6000, rm7000, 8000, rm9000,

+ 5kc, 5kf, 20kc, 25kf, sb1, sb1a, loongson2e, loongson2f,
+ loongson3a, octeon, octeon+, octeon2, xlr, xlp
+
+ For compatibility reasons, `Nx' and `Bfx' are accepted as synonyms
+ for `Nf1_1'. These values are deprecated.
+
+`-mtune=CPU'
+ Schedule and tune for a particular MIPS CPU. Valid CPU values are
+ identical to `-march=CPU'.
+
+`-mabi=ABI'
+ Record which ABI the source code uses. The recognized arguments
+ are: `32', `n32', `o64', `64' and `eabi'.
+
+`-msym32'
+`-mno-sym32'
+ Equivalent to adding `.set sym32' or `.set nosym32' to the
+ beginning of the assembler input. *Note MIPS Symbol Sizes::.
+
+`-nocpp'
+ This option is ignored. It is accepted for command-line
+ compatibility with other assemblers, which use it to turn off C
+ style preprocessing. With GNU `as', there is no need for
+ `-nocpp', because the GNU assembler itself never runs the C
+ preprocessor.
+
+`-msoft-float'
+`-mhard-float'
+ Disable or enable floating-point instructions. Note that by
+ default floating-point instructions are always allowed even with
+ CPU targets that don't have support for these instructions.
+
+`-msingle-float'
+`-mdouble-float'
+ Disable or enable double-precision floating-point operations. Note
+ that by default double-precision floating-point operations are
+ always allowed even with CPU targets that don't have support for
+ these operations.
+
+`--construct-floats'
+`--no-construct-floats'
+ The `--no-construct-floats' option disables the construction of
+ double width floating point constants by loading the two halves of
+ the value into the two single width floating point registers that
+ make up the double width register. This feature is useful if the
+ processor support the FR bit in its status register, and this bit
+ is known (by the programmer) to be set. This bit prevents the
+ aliasing of the double width register by the single width
+ registers.
+
+ By default `--construct-floats' is selected, allowing construction
+ of these floating point constants.
+
+`--relax-branch'
+`--no-relax-branch'
+ The `--relax-branch' option enables the relaxation of out-of-range
+ branches. Any branches whose target cannot be reached directly are
+ converted to a small instruction sequence including an
+ inverse-condition branch to the physically next instruction, and a
+ jump to the original target is inserted between the two
+ instructions. In PIC code the jump will involve further
+ instructions for address calculation.
+
+ The `BC1ANY2F', `BC1ANY2T', `BC1ANY4F', `BC1ANY4T', `BPOSGE32' and
+ `BPOSGE64' instructions are excluded from relaxation, because they
+ have no complementing counterparts. They could be relaxed with
+ the use of a longer sequence involving another branch, however
+ this has not been implemented and if their target turns out of
+ reach, they produce an error even if branch relaxation is enabled.
+
+ Also no MIPS16 branches are ever relaxed.
+
+ By default `--no-relax-branch' is selected, causing any
+ out-of-range branches to produce an error.
+
+`-mnan=ENCODING'
+ This option indicates whether the source code uses the IEEE 2008
+ NaN encoding (`-mnan=2008') or the original MIPS encoding
+ (`-mnan=legacy'). It is equivalent to adding a `.nan' directive
+ to the beginning of the source file. *Note MIPS NaN Encodings::.
+
+ `-mnan=legacy' is the default if no `-mnan' option or `.nan'
+ directive is used.
+
+`--trap'
+`--no-break'
+ `as' automatically macro expands certain division and
+ multiplication instructions to check for overflow and division by
+ zero. This option causes `as' to generate code to take a trap
+ exception rather than a break exception when an error is detected.
+ The trap instructions are only supported at Instruction Set
+ Architecture level 2 and higher.
+
+`--break'
+`--no-trap'
+ Generate code to take a break exception rather than a trap
+ exception when an error is detected. This is the default.
+
+`-mpdr'
+`-mno-pdr'
+ Control generation of `.pdr' sections. Off by default on IRIX, on
+ elsewhere.
+
+`-mshared'
+`-mno-shared'
+ When generating code using the Unix calling conventions (selected
+ by `-KPIC' or `-mcall_shared'), gas will normally generate code
+ which can go into a shared library. The `-mno-shared' option
+ tells gas to generate code which uses the calling convention, but
+ can not go into a shared library. The resulting code is slightly
+ more efficient. This option only affects the handling of the
+ `.cpload' and `.cpsetup' pseudo-ops.

+9.27.2 High-level assembly macros
+---------------------------------
+
+MIPS assemblers have traditionally provided a wider range of
+instructions than the MIPS architecture itself. These extra
+instructions are usually referred to as "macro" instructions (1).
+
+ Some MIPS macro instructions extend an underlying architectural
+instruction while others are entirely new. An example of the former
+type is `and', which allows the third operand to be either a register
+or an arbitrary immediate value. Examples of the latter type include
+`bgt', which branches to the third operand when the first operand is
+greater than the second operand, and `ulh', which implements an
+unaligned 2-byte load.
+
+ One of the most common extensions provided by macros is to expand
+memory offsets to the full address range (32 or 64 bits) and to allow
+symbolic offsets such as `my_data + 4' to be used in place of integer
+constants. For example, the architectural instruction `lbu' allows
+only a signed 16-bit offset, whereas the macro `lbu' allows code such
+as `lbu $4,array+32769($5)'. The implementation of these symbolic
+offsets depends on several factors, such as whether the assembler is
+generating SVR4-style PIC (selected by `-KPIC', *note Assembler
+options: MIPS Options.), the size of symbols (*note Directives to
+override the size of symbols: MIPS Symbol Sizes.), and the small data
+limit (*note Controlling the use of small data accesses: MIPS Small
+Data.).
+
+ Sometimes it is undesirable to have one assembly instruction expand
+to several machine instructions. The directive `.set nomacro' tells
+the assembler to warn when this happens. `.set macro' restores the
+default behavior.
+
+ Some macro instructions need a temporary register to store
+intermediate results. This register is usually `$1', also known as
+`$at', but it can be changed to any core register REG using `.set
+at=REG'. Note that `$at' always refers to `$1' regardless of which
+register is being used as the temporary register.
+
+ Implicit uses of the temporary register in macros could interfere
+with explicit uses in the assembly code. The assembler therefore warns
+whenever it sees an explicit use of the temporary register. The
+directive `.set noat' silences this warning while `.set at' restores
+the default behavior. It is safe to use `.set noat' while `.set
+nomacro' is in effect since single-instruction macros never need a
+temporary register.
+
+ Note that while the GNU assembler provides these macros for
+compatibility, it does not make any attempt to optimize them with the
+surrounding code.
+
+ ---------- Footnotes ----------
+
+ (1) The term "macro" is somewhat overloaded here, since these macros
+have no relation to those defined by `.macro', *note `.macro': Macro.

+
+9.27.3 Directives to override the size of symbols
+-------------------------------------------------
+
+The n64 ABI allows symbols to have any 64-bit value. Although this
+provides a great deal of flexibility, it means that some macros have
+much longer expansions than their 32-bit counterparts. For example,
+the non-PIC expansion of `dla $4,sym' is usually:
+
+ lui $4,%highest(sym)
+ lui $1,%hi(sym)
+ daddiu $4,$4,%higher(sym)
+ daddiu $1,$1,%lo(sym)
+ dsll32 $4,$4,0
+ daddu $4,$4,$1
+
+ whereas the 32-bit expansion is simply:
+
+ lui $4,%hi(sym)
+ daddiu $4,$4,%lo(sym)
+
+ n64 code is sometimes constructed in such a way that all symbolic
+constants are known to have 32-bit values, and in such cases, it's
+preferable to use the 32-bit expansion instead of the 64-bit expansion.
+
+ You can use the `.set sym32' directive to tell the assembler that,
+from this point on, all expressions of the form `SYMBOL' or `SYMBOL +
+OFFSET' have 32-bit values. For example:
+
+ .set sym32
+ dla $4,sym
+ lw $4,sym+16
+ sw $4,sym+0x8000($4)
+
+ will cause the assembler to treat `sym', `sym+16' and `sym+0x8000'
+as 32-bit values. The handling of non-symbolic addresses is not
+affected.
+
+ The directive `.set nosym32' ends a `.set sym32' block and reverts
+to the normal behavior. It is also possible to change the symbol size
+using the command-line options `-msym32' and `-mno-sym32'.
+
+ These options and directives are always accepted, but at present,
+they have no effect for anything other than n64.
+
+
+File: as.info, Node: MIPS Small Data, Next: MIPS ISA, Prev: MIPS Symbol Sizes, Up: MIPS-Dependent
+
+9.27.4 Controlling the use of small data accesses
+-------------------------------------------------
+
+It often takes several instructions to load the address of a symbol.
+For example, when `addr' is a 32-bit symbol, the non-PIC expansion of
+`dla $4,addr' is usually:
+
+ lui $4,%hi(addr)
+ daddiu $4,$4,%lo(addr)
+
+ The sequence is much longer when `addr' is a 64-bit symbol. *Note
+Directives to override the size of symbols: MIPS Symbol Sizes.
+
+ In order to cut down on this overhead, most embedded MIPS systems
+set aside a 64-kilobyte "small data" area and guarantee that all data
+of size N and smaller will be placed in that area. The limit N is
+passed to both the assembler and the linker using the command-line
+option `-G N', *note Assembler options: MIPS Options. Note that the
+same value of N must be used when linking and when assembling all input
+files to the link; any inconsistency could cause a relocation overflow
+error.
+
+ The size of an object in the `.bss' section is set by the `.comm' or
+`.lcomm' directive that defines it. The size of an external object may
+be set with the `.extern' directive. For example, `.extern sym,4'
+declares that the object at `sym' is 4 bytes in length, while leaving
+`sym' otherwise undefined.
+
+ When no `-G' option is given, the default limit is 8 bytes. The
+option `-G 0' prevents any data from being automatically classified as
+small.
+
+ It is also possible to mark specific objects as small by putting them
+in the special sections `.sdata' and `.sbss', which are "small"
+counterparts of `.data' and `.bss' respectively. The toolchain will
+treat such data as small regardless of the `-G' setting.
+
+ On startup, systems that support a small data area are expected to
+initialize register `$28', also known as `$gp', in such a way that
+small data can be accessed using a 16-bit offset from that register.
+For example, when `addr' is small data, the `dla $4,addr' instruction
+above is equivalent to:
+
+ daddiu $4,$28,%gp_rel(addr)
+
+ Small data is not supported for SVR4-style PIC.

+
+9.27.5 Directives to override the ISA level
+-------------------------------------------
+
+GNU `as' supports an additional directive to change the MIPS
+Instruction Set Architecture level on the fly: `.set mipsN'. N should
+be a number from 0 to 5, or 32, 32r2, 32r3, 32r5, 32r6, 64, 64r2, 64r3,
+64r5 or 64r6. The values other than 0 make the assembler accept
+instructions for the corresponding ISA level, from that point on in the
+assembly. `.set mipsN' affects not only which instructions are
+permitted, but also how certain macros are expanded. `.set mips0'
+restores the ISA level to its original level: either the level you
+selected with command line options, or the default for your
+configuration. You can use this feature to permit specific MIPS III
+instructions while assembling in 32 bit mode. Use this directive with
+care!
+
+ The `.set arch=CPU' directive provides even finer control. It
+changes the effective CPU target and allows the assembler to use
+instructions specific to a particular CPU. All CPUs supported by the
+`-march' command line option are also selectable by this directive.
+The original value is restored by `.set arch=default'.
+
+ The directive `.set mips16' puts the assembler into MIPS 16 mode, in
+which it will assemble instructions for the MIPS 16 processor. Use
+`.set nomips16' to return to normal 32 bit mode.
+
+ Traditional MIPS assemblers do not support this directive.
+
+ The directive `.set micromips' puts the assembler into microMIPS
+mode, in which it will assemble instructions for the microMIPS
+processor. Use `.set nomicromips' to return to normal 32 bit mode.
+
+ Traditional MIPS assemblers do not support this directive.
+

+File: as.info, Node: MIPS assembly options, Next: MIPS autoextend, Prev: MIPS ISA, Up: MIPS-Dependent
+
+9.27.6 Directives to control code generation
+--------------------------------------------
+
+The `.module' directive allows command line options to be set directly
+from assembly. The format of the directive matches the `.set'
+directive but only those options which are relevant to a whole module
+are supported. The effect of a `.module' directive is the same as the
+corresponding command line option. Where `.set' directives support
+returning to a default then the `.module' directives do not as they
+define the defaults.
+
+ These module-level directives must appear first in assembly.
+
+ Traditional MIPS assemblers do not support this directive.
+
+ The directive `.set insn32' makes the assembler only use 32-bit
+instruction encodings when generating code for the microMIPS processor.
+This directive inhibits the use of any 16-bit instructions from that
+point on in the assembly. The `.set noinsn32' directive allows 16-bit
+instructions to be accepted.
+
+ Traditional MIPS assemblers do not support this directive.
+
+
+File: as.info, Node: MIPS autoextend, Next: MIPS insn, Prev: MIPS assembly options, Up: MIPS-Dependent
+
+9.27.7 Directives for extending MIPS 16 bit instructions
+--------------------------------------------------------
+
+By default, MIPS 16 instructions are automatically extended to 32 bits
+when necessary. The directive `.set noautoextend' will turn this off.
+When `.set noautoextend' is in effect, any 32 bit instruction must be
+explicitly extended with the `.e' modifier (e.g., `li.e $4,1000'). The
+directive `.set autoextend' may be used to once again automatically
+extend instructions when necessary.
+
+ This directive is only meaningful when in MIPS 16 mode. Traditional
+MIPS assemblers do not support this directive.
+
+
+File: as.info, Node: MIPS insn, Next: MIPS FP ABIs, Prev: MIPS autoextend, Up: MIPS-Dependent
+
+9.27.8 Directive to mark data as an instruction
+-----------------------------------------------
+
+The `.insn' directive tells `as' that the following data is actually
+instructions. This makes a difference in MIPS 16 and microMIPS modes:
+when loading the address of a label which precedes instructions, `as'
+automatically adds 1 to the value, so that jumping to the loaded
+address will do the right thing.
+
+ The `.global' and `.globl' directives supported by `as' will by
+default mark the symbol as pointing to a region of data not code. This
+means that, for example, any instructions following such a symbol will
+not be disassembled by `objdump' as it will regard them as data. To
+change this behavior an optional section name can be placed after the
+symbol name in the `.global' directive. If this section exists and is
+known to be a code section, then the symbol will be marked as pointing
+at code not data. Ie the syntax for the directive is:
+
+ `.global SYMBOL[ SECTION][, SYMBOL[ SECTION]] ...',
+
+ Here is a short example:
+
+ .global foo .text, bar, baz .data
+ foo:
+ nop
+ bar:
+ .word 0x0
+ baz:
+ .word 0x1

+
+9.27.9.1 History of FP ABIs
+...........................
+
+The MIPS ABIs support a variety of different floating-point extensions
+where calling-convention and register sizes vary for floating-point
+data. The extensions exist to support a wide variety of optional
+architecture features. The resulting ABI variants are generally
+incompatible with each other and must be tracked carefully.
+
+ Traditionally the use of an explicit `.gnu_attribute 4, N' directive
+is used to indicate which ABI is in use by a specific module. It was
+then left to the user to ensure that command line options and the
+selected ABI were compatible with some potential for inconsistencies.
+
+
+File: as.info, Node: MIPS FP ABI Variants, Next: MIPS FP ABI Selection, Prev: MIPS FP ABI History, Up: MIPS FP ABIs
+
+9.27.9.2 Supported FP ABIs
+..........................
+
+The supported floating-point ABI variants are:
+
+`0 - No floating-point'
+ This variant is used to indicate that floating-point is not used
+ within the module at all and therefore has no impact on the ABI.
+ This is the default.
+
+`1 - Double-precision'
+ This variant indicates that double-precision support is used. For
+ 64-bit ABIs this means that 64-bit wide floating-point registers
+ are required. For 32-bit ABIs this means that 32-bit wide
+ floating-point registers are required and double-precision
+ operations use pairs of registers.
+
+`2 - Single-precision'
+ This variant indicates that single-precision support is used.
+ Double precision operations will be supported via soft-float
+ routines.
+
+`3 - Soft-float'
+ This variant indicates that although floating-point support is
+ used all operations are emulated in software. This means the ABI
+ is modified to pass all floating-point data in general-purpose
+ registers.
+
+`4 - Deprecated'
+ This variant existed as an initial attempt at supporting 64-bit
+ wide floating-point registers for O32 ABI on a MIPS32r2 CPU. This
+ has been superseded by 5, 6 and 7.
+
+`5 - Double-precision 32-bit CPU, 32-bit or 64-bit FPU'
+ This variant is used by 32-bit ABIs to indicate that the
+ floating-point code in the module has been designed to operate
+ correctly with either 32-bit wide or 64-bit wide floating-point
+ registers. Double-precision support is used. Only O32 currently
+ supports this variant and requires a minimum architecture of MIPS
+ II.
+
+`6 - Double-precision 32-bit FPU, 64-bit FPU'
+ This variant is used by 32-bit ABIs to indicate that the
+ floating-point code in the module requires 64-bit wide
+ floating-point registers. Double-precision support is used. Only
+ O32 currently supports this variant and requires a minimum
+ architecture of MIPS32r2.
+
+`7 - Double-precision compat 32-bit FPU, 64-bit FPU'
+ This variant is used by 32-bit ABIs to indicate that the
+ floating-point code in the module requires 64-bit wide
+ floating-point registers. Double-precision support is used. This
+ differs from the previous ABI as it restricts use of odd-numbered
+ single-precision registers. Only O32 currently supports this
+ variant and requires a minimum architecture of MIPS32r2.

+
+9.27.9.3 Automatic selection of FP ABI
+......................................
+
+In order to simplify and add safety to the process of selecting the
+correct floating-point ABI, the assembler will automatically infer the
+correct `.gnu_attribute 4, N' directive based on command line options
+and `.module' overrides. Where an explicit `.gnu_attribute 4, N'
+directive has been seen then a warning will be raised if it does not
+match an inferred setting.
+
+ The floating-point ABI is inferred as follows. If `-msoft-float'
+has been used the module will be marked as soft-float. If
+`-msingle-float' has been used then the module will be marked as
+single-precision. The remaining ABIs are then selected based on the FP
+register width. Double-precision is selected if the width of GP and FP
+registers match and the special double-precision variants for 32-bit
+ABIs are then selected depending on `-mfpxx', `-mfp64' and
+`-mno-odd-spreg'.
+
+
+File: as.info, Node: MIPS FP ABI Compatibility, Prev: MIPS FP ABI Selection, Up: MIPS FP ABIs
+
+9.27.9.4 Linking different FP ABI variants
+..........................................
+
+Modules using the default FP ABI (no floating-point) can be linked with
+any other (singular) FP ABI variant.
+
+ Special compatibility support exists for O32 with the four
+double-precision FP ABI variants. The `-mfpxx' FP ABI is specifically
+designed to be compatible with the standard double-precision ABI and the
+`-mfp64' FP ABIs. This makes it desirable for O32 modules to be built
+as `-mfpxx' to ensure the maximum compatibility with other modules
+produced for more specific needs. The only FP ABIs which cannot be
+linked together are the standard double-precision ABI and the full
+`-mfp64' ABI with `-modd-spreg'.

+
+9.27.10 Directives to record which NaN encoding is being used
+-------------------------------------------------------------
+
+The IEEE 754 floating-point standard defines two types of not-a-number
+(NaN) data: "signalling" NaNs and "quiet" NaNs. The original version
+of the standard did not specify how these two types should be
+distinguished. Most implementations followed the i387 model, in which
+the first bit of the significand is set for quiet NaNs and clear for
+signalling NaNs. However, the original MIPS implementation assigned the
+opposite meaning to the bit, so that it was set for signalling NaNs and
+clear for quiet NaNs.
+
+ The 2008 revision of the standard formally suggested the i387 choice
+and as from Sep 2012 the current release of the MIPS architecture
+therefore optionally supports that form. Code that uses one NaN
+encoding would usually be incompatible with code that uses the other
+NaN encoding, so MIPS ELF objects have a flag (`EF_MIPS_NAN2008') to
+record which encoding is being used.
+
+ Assembly files can use the `.nan' directive to select between the
+two encodings. `.nan 2008' says that the assembly file uses the IEEE
+754-2008 encoding while `.nan legacy' says that the file uses the
+original MIPS encoding. If several `.nan' directives are given, the
+final setting is the one that is used.
+
+ The command-line options `-mnan=legacy' and `-mnan=2008' can be used
+instead of `.nan legacy' and `.nan 2008' respectively. However, any
+`.nan' directive overrides the command-line setting.
+
+ `.nan legacy' is the default if no `.nan' directive or `-mnan'
+option is given.
+
+ Note that GNU `as' does not produce NaNs itself and therefore these
+directives do not affect code generation. They simply control the
+setting of the `EF_MIPS_NAN2008' flag.
+
+ Traditional MIPS assemblers do not support these directives.

+----------------------------------------------
+
+The directives `.set push' and `.set pop' may be used to save and

+stack. The `.set pop' directive pops the stack and restores the
+settings.
+
+ These directives can be useful inside an macro which must change an
+option such as the ISA level or instruction reordering but does not want
+to change the state of the code which invoked the macro.

+File: as.info, Node: MMIX-Opts, Next: MMIX-Expand, Up: MMIX-Dependent
+
+9.28.1 Command-line Options
+---------------------------
+
+The MMIX version of `as' has some machine-dependent options.
+
+ When `--fixed-special-register-names' is specified, only the register
+names specified in *Note MMIX-Regs:: are recognized in the instructions
+`PUT' and `GET'.
+
+ You can use the `--globalize-symbols' to make all symbols global.
+This option is useful when splitting up a `mmixal' program into several
+files.
+
+ The `--gnu-syntax' turns off most syntax compatibility with
+`mmixal'. Its usability is currently doubtful.
+
+ The `--relax' option is not fully supported, but will eventually make
+the object file prepared for linker relaxation.
+
+ If you want to avoid inadvertently calling a predefined symbol and
+would rather get an error, for example when using `as' with a compiler
+or other machine-generated code, specify `--no-predefined-syms'. This
+turns off built-in predefined definitions of all such symbols,
+including rounding-mode symbols, segment symbols, `BIT' symbols, and
+`TRAP' symbols used in `mmix' "system calls". It also turns off
+predefined special-register names, except when used in `PUT' and `GET'
+instructions.
+
+ By default, some instructions are expanded to fit the size of the
+operand or an external symbol (*note MMIX-Expand::). By passing
+`--no-expand', no such expansion will be done, instead causing errors
+at link time if the operand does not fit.
+
+ The `mmixal' documentation (*note mmixsite::) specifies that global
+registers allocated with the `GREG' directive (*note MMIX-greg::) and
+initialized to the same non-zero value, will refer to the same global
+register. This isn't strictly enforceable in `as' since the final
+addresses aren't known until link-time, but it will do an effort unless
+the `--no-merge-gregs' option is specified. (Register merging isn't
+yet implemented in `ld'.)
+
+ `as' will warn every time it expands an instruction to fit an
+operand unless the option `-x' is specified. It is believed that this
+behaviour is more useful than just mimicking `mmixal''s behaviour, in
+which instructions are only expanded if the `-x' option is specified,
+and assembly fails otherwise, when an instruction needs to be expanded.
+It needs to be kept in mind that `mmixal' is both an assembler and
+linker, while `as' will expand instructions that at link stage can be
+contracted. (Though linker relaxation isn't yet implemented in `ld'.)
+The option `-x' also imples `--linker-allocated-gregs'.
+
+ If instruction expansion is enabled, `as' can expand a `PUSHJ'
+instruction into a series of instructions. The shortest expansion is
+to not expand it, but just mark the call as redirectable to a stub,
+which `ld' creates at link-time, but only if the original `PUSHJ'
+instruction is found not to reach the target. The stub consists of the
+necessary instructions to form a jump to the target. This happens if
+`as' can assert that the `PUSHJ' instruction can reach such a stub.
+The option `--no-pushj-stubs' disables this shorter expansion, and the
+longer series of instructions is then created at assembly-time. The
+option `--no-stubs' is a synonym, intended for compatibility with
+future releases, where generation of stubs for other instructions may
+be implemented.
+
+ Usually a two-operand-expression (*note GREG-base::) without a
+matching `GREG' directive is treated as an error by `as'. When the
+option `--linker-allocated-gregs' is in effect, they are instead passed
+through to the linker, which will allocate as many global registers as
+is needed.

+9.28.2 Instruction expansion
+----------------------------
+
+When `as' encounters an instruction with an operand that is either not
+known or does not fit the operand size of the instruction, `as' (and
+`ld') will expand the instruction into a sequence of instructions
+semantically equivalent to the operand fitting the instruction.
+Expansion will take place for the following instructions:
+
+`GETA'
+ Expands to a sequence of four instructions: `SETL', `INCML',
+ `INCMH' and `INCH'. The operand must be a multiple of four.
+
+Conditional branches
+ A branch instruction is turned into a branch with the complemented
+ condition and prediction bit over five instructions; four
+ instructions setting `$255' to the operand value, which like with
+ `GETA' must be a multiple of four, and a final `GO $255,$255,0'.
+
+`PUSHJ'
+ Similar to expansion for conditional branches; four instructions
+ set `$255' to the operand value, followed by a `PUSHGO
+ $255,$255,0'.
+
+`JMP'
+ Similar to conditional branches and `PUSHJ'. The final instruction
+ is `GO $255,$255,0'.
+
+ The linker `ld' is expected to shrink these expansions for code
+assembled with `--relax' (though not currently implemented).

+
+9.28.3 Syntax
+-------------
+
+The assembly syntax is supposed to be upward compatible with that
+described in Sections 1.3 and 1.4 of `The Art of Computer Programming,
+Volume 1'. Draft versions of those chapters as well as other MMIX
+information is located at
+`http://www-cs-faculty.stanford.edu/~knuth/mmix-news.html'. Most code
+examples from the mmixal package located there should work unmodified
+when assembled and linked as single files, with a few noteworthy
+exceptions (*note MMIX-mmixal::).
+
+ Before an instruction is emitted, the current location is aligned to
+the next four-byte boundary. If a label is defined at the beginning of
+the line, its value will be the aligned value.
+
+ In addition to the traditional hex-prefix `0x', a hexadecimal number
+can also be specified by the prefix character `#'.
+
+ After all operands to an MMIX instruction or directive have been
+specified, the rest of the line is ignored, treated as a comment.

+
+9.28.3.1 Special Characters
+...........................
+
+The characters `*' and `#' are line comment characters; each start a
+comment at the beginning of a line, but only at the beginning of a
+line. A `#' prefixes a hexadecimal number if found elsewhere on a
+line. If a `#' appears at the start of a line the whole line is
+treated as a comment, but the line can also act as a logical line
+number directive (*note Comments::) or a preprocessor control command
+(*note Preprocessing::).
+
+ Two other characters, `%' and `!', each start a comment anywhere on
+the line. Thus you can't use the `modulus' and `not' operators in
+expressions normally associated with these two characters.
+
+ A `;' is a line separator, treated as a new-line, so separate
+instructions can be specified on a single line.
+
+
+File: as.info, Node: MMIX-Symbols, Next: MMIX-Regs, Prev: MMIX-Chars, Up: MMIX-Syntax
+
+9.28.3.2 Symbols
+................
+
+The character `:' is permitted in identifiers. There are two
+exceptions to it being treated as any other symbol character: if a
+symbol begins with `:', it means that the symbol is in the global
+namespace and that the current prefix should not be prepended to that
+symbol (*note MMIX-prefix::). The `:' is then not considered part of
+the symbol. For a symbol in the label position (first on a line), a `:'
+at the end of a symbol is silently stripped off. A label is permitted,
+but not required, to be followed by a `:', as with many other assembly
+formats.
+
+ The character `@' in an expression, is a synonym for `.', the
+current location.
+
+ In addition to the common forward and backward local symbol formats
+(*note Symbol Names::), they can be specified with upper-case `B' and
+`F', as in `8B' and `9F'. A local label defined for the current
+position is written with a `H' appended to the number:
+ 3H LDB $0,$1,2
+ This and traditional local-label formats cannot be mixed: a label
+must be defined and referred to using the same format.
+
+ There's a minor caveat: just as for the ordinary local symbols, the
+local symbols are translated into ordinary symbols using control
+characters are to hide the ordinal number of the symbol.
+Unfortunately, these symbols are not translated back in error messages.
+Thus you may see confusing error messages when local symbols are used.
+Control characters `\003' (control-C) and `\004' (control-D) are used
+for the MMIX-specific local-symbol syntax.
+
+ The symbol `Main' is handled specially; it is always global.
+
+ By defining the symbols `__.MMIX.start..text' and
+`__.MMIX.start..data', the address of respectively the `.text' and
+`.data' segments of the final program can be defined, though when
+linking more than one object file, the code or data in the object file
+containing the symbol is not guaranteed to be start at that position;
+just the final executable. *Note MMIX-loc::.

+
+9.28.3.3 Register names
+.......................
+
+Local and global registers are specified as `$0' to `$255'. The
+recognized special register names are `rJ', `rA', `rB', `rC', `rD',
+`rE', `rF', `rG', `rH', `rI', `rK', `rL', `rM', `rN', `rO', `rP', `rQ',
+`rR', `rS', `rT', `rU', `rV', `rW', `rX', `rY', `rZ', `rBB', `rTT',
+`rWW', `rXX', `rYY' and `rZZ'. A leading `:' is optional for special
+register names.
+
+ Local and global symbols can be equated to register names and used in
+place of ordinary registers.
+
+ Similarly for special registers, local and global symbols can be
+used. Also, symbols equated from numbers and constant expressions are
+allowed in place of a special register, except when either of the
+options `--no-predefined-syms' and `--fixed-special-register-names' are
+specified. Then only the special register names above are allowed for
+the instructions having a special register operand; `GET' and `PUT'.
+
+

+
+9.28.3.4 Assembler Directives
+.............................
+
+`LOC'
+ The `LOC' directive sets the current location to the value of the
+ operand field, which may include changing sections. If the
+ operand is a constant, the section is set to either `.data' if the
+ value is `0x2000000000000000' or larger, else it is set to `.text'.
+ Within a section, the current location may only be changed to
+ monotonically higher addresses. A LOC expression must be a
+ previously defined symbol or a "pure" constant.
+
+ An example, which sets the label PREV to the current location, and
+ updates the current location to eight bytes forward:
+ prev LOC @+8
+
+ When a LOC has a constant as its operand, a symbol
+ `__.MMIX.start..text' or `__.MMIX.start..data' is defined
+ depending on the address as mentioned above. Each such symbol is
+ interpreted as special by the linker, locating the section at that
+ address. Note that if multiple files are linked, the first object
+ file with that section will be mapped to that address (not
+ necessarily the file with the LOC definition).
+
+`LOCAL'
+ Example:
+ LOCAL external_symbol
+ LOCAL 42
+ .local asymbol
+
+ This directive-operation generates a link-time assertion that the
+ operand does not correspond to a global register. The operand is
+ an expression that at link-time resolves to a register symbol or a
+ number. A number is treated as the register having that number.
+ There is one restriction on the use of this directive: the
+ pseudo-directive must be placed in a section with contents, code
+ or data.
+
+`IS'
+ The `IS' directive:
+ asymbol IS an_expression
+ sets the symbol `asymbol' to `an_expression'. A symbol may not be
+ set more than once using this directive. Local labels may be set
+ using this directive, for example:
+ 5H IS @+4
+
+`GREG'
+ This directive reserves a global register, gives it an initial
+ value and optionally gives it a symbolic name. Some examples:
+
+ areg GREG
+ breg GREG data_value
+ GREG data_buffer
+ .greg creg, another_data_value
+
+ The symbolic register name can be used in place of a (non-special)
+ register. If a value isn't provided, it defaults to zero. Unless
+ the option `--no-merge-gregs' is specified, non-zero registers
+ allocated with this directive may be eliminated by `as'; another
+ register with the same value used in its place. Any of the
+ instructions `CSWAP', `GO', `LDA', `LDBU', `LDB', `LDHT', `LDOU',
+ `LDO', `LDSF', `LDTU', `LDT', `LDUNC', `LDVTS', `LDWU', `LDW',
+ `PREGO', `PRELD', `PREST', `PUSHGO', `STBU', `STB', `STCO', `STHT',
+ `STOU', `STSF', `STTU', `STT', `STUNC', `SYNCD', `SYNCID', can
+ have a value nearby an initial value in place of its second and
+ third operands. Here, "nearby" is defined as within the range
+ 0...255 from the initial value of such an allocated register.
+
+ buffer1 BYTE 0,0,0,0,0
+ buffer2 BYTE 0,0,0,0,0
+ ...
+ GREG buffer1
+ LDOU $42,buffer2
+ In the example above, the `Y' field of the `LDOUI' instruction
+ (LDOU with a constant Z) will be replaced with the global register
+ allocated for `buffer1', and the `Z' field will have the value 5,
+ the offset from `buffer1' to `buffer2'. The result is equivalent
+ to this code:
+ buffer1 BYTE 0,0,0,0,0
+ buffer2 BYTE 0,0,0,0,0
+ ...
+ tmpreg GREG buffer1
+ LDOU $42,tmpreg,(buffer2-buffer1)
+
+ Global registers allocated with this directive are allocated in
+ order higher-to-lower within a file. Other than that, the exact
+ order of register allocation and elimination is undefined. For
+ example, the order is undefined when more than one file with such
+ directives are linked together. With the options `-x' and
+ `--linker-allocated-gregs', `GREG' directives for two-operand
+ cases like the one mentioned above can be omitted. Sufficient
+ global registers will then be allocated by the linker.
+
+`BYTE'
+ The `BYTE' directive takes a series of operands separated by a
+ comma. If an operand is a string (*note Strings::), each
+ character of that string is emitted as a byte. Other operands
+ must be constant expressions without forward references, in the
+ range 0...255. If you need operands having expressions with
+ forward references, use `.byte' (*note Byte::). An operand can be
+ omitted, defaulting to a zero value.
+
+`WYDE'
+`TETRA'
+`OCTA'
+ The directives `WYDE', `TETRA' and `OCTA' emit constants of two,
+ four and eight bytes size respectively. Before anything else
+ happens for the directive, the current location is aligned to the
+ respective constant-size boundary. If a label is defined at the
+ beginning of the line, its value will be that after the alignment.
+ A single operand can be omitted, defaulting to a zero value
+ emitted for the directive. Operands can be expressed as strings
+ (*note Strings::), in which case each character in the string is
+ emitted as a separate constant of the size indicated by the
+ directive.
+
+`PREFIX'
+ The `PREFIX' directive sets a symbol name prefix to be prepended to
+ all symbols (except local symbols, *note MMIX-Symbols::), that are
+ not prefixed with `:', until the next `PREFIX' directive. Such
+ prefixes accumulate. For example,
+ PREFIX a
+ PREFIX b
+ c IS 0
+ defines a symbol `abc' with the value 0.
+
+`BSPEC'
+`ESPEC'
+ A pair of `BSPEC' and `ESPEC' directives delimit a section of
+ special contents (without specified semantics). Example:
+ BSPEC 42
+ TETRA 1,2,3
+ ESPEC
+ The single operand to `BSPEC' must be number in the range 0...255.
+ The `BSPEC' number 80 is used by the GNU binutils implementation.

+
+9.28.4 Differences to `mmixal'
+------------------------------
+
+The binutils `as' and `ld' combination has a few differences in
+function compared to `mmixal' (*note mmixsite::).
+
+ The replacement of a symbol with a GREG-allocated register (*note
+GREG-base::) is not handled the exactly same way in `as' as in
+`mmixal'. This is apparent in the `mmixal' example file `inout.mms',
+where different registers with different offsets, eventually yielding
+the same address, are used in the first instruction. This type of
+difference should however not affect the function of any program unless
+it has specific assumptions about the allocated register number.
+
+ Line numbers (in the `mmo' object format) are currently not
+supported.
+
+ Expression operator precedence is not that of mmixal: operator
+precedence is that of the C programming language. It's recommended to
+use parentheses to explicitly specify wanted operator precedence
+whenever more than one type of operators are used.
+
+ The serialize unary operator `&', the fractional division operator
+`//', the logical not operator `!' and the modulus operator `%' are not
+available.
+
+ Symbols are not global by default, unless the option
+`--globalize-symbols' is passed. Use the `.global' directive to
+globalize symbols (*note Global::).
+
+ Operand syntax is a bit stricter with `as' than `mmixal'. For
+example, you can't say `addu 1,2,3', instead you must write `addu
+$1,$2,3'.
+
+ You can't LOC to a lower address than those already visited (i.e.,
+"backwards").
+
+ A LOC directive must come before any emitted code.
+
+ Predefined symbols are visible as file-local symbols after use. (In
+the ELF file, that is--the linked mmo file has no notion of a file-local
+symbol.)
+
+ Some mapping of constant expressions to sections in LOC expressions
+is attempted, but that functionality is easily confused and should be
+avoided unless compatibility with `mmixal' is required. A LOC
+expression to `0x2000000000000000' or higher, maps to the `.data'
+section and lower addresses map to the `.text' section (*note
+MMIX-loc::).
+
+ The code and data areas are each contiguous. Sparse programs with
+far-away LOC directives will take up the same amount of space as a
+contiguous program with zeros filled in the gaps between the LOC
+directives. If you need sparse programs, you might try and get the
+wanted effect with a linker script and splitting up the code parts into
+sections (*note Section::). Assembly code for this, to be compatible
+with `mmixal', would look something like:
+ .if 0
+ LOC away_expression
+ .else
+ .section away,"ax"
+ .fi
+ `as' will not execute the LOC directive and `mmixal' ignores the
+lines with `.'. This construct can be used generally to help
+compatibility.
+
+ Symbols can't be defined twice-not even to the same value.
+
+ Instruction mnemonics are recognized case-insensitive, though the
+`IS' and `GREG' pseudo-operations must be specified in upper-case
+characters.
+
+ There's no unicode support.
+
+ The following is a list of programs in `mmix.tar.gz', available at
+`http://www-cs-faculty.stanford.edu/~knuth/mmix-news.html', last
+checked with the version dated 2001-08-25 (md5sum
+c393470cfc86fac040487d22d2bf0172) that assemble with `mmixal' but do
+not assemble with `as':
+
+`silly.mms'
+ LOC to a previous address.
+
+`sim.mms'
+ Redefines symbol `Done'.
+
+`test.mms'
+ Uses the serial operator `&'.

+--------------
+
+`-mmcu'
+ selects the mcu architecture. If the architecture is 430Xv2 then
+ this also enables NOP generation unless the `-mN' is also
+ specified.
+
+`-mcpu'
+ selects the cpu architecture. If the architecture is 430Xv2 then

+
+`-mQ'
+ enables relaxation at assembly time. DANGEROUS!
+
+`-ml'
+ indicates that the input uses the large code model.
+
+`-mn'
+ enables the generation of a NOP instruction following any
+ instruction that might change the interrupts enabled/disabled
+ state. The pipelined nature of the MSP430 core means that any
+ instruction that changes the interrupt state (`EINT', `DINT', `BIC
+ #8, SR', `BIS #8, SR' or `MOV.W <>, SR') must be followed by a NOP
+ instruction in order to ensure the correct processing of
+ interrupts. By default it is up to the programmer to supply these
+ NOP instructions, but this command line option enables the
+ automatic insertion by the assembler, if they are missing.
+
+`-mN'
+ disables the generation of a NOP instruction following any
+ instruction that might change the interrupts enabled/disabled
+ state. This is the default behaviour.
+
+`-my'
+ tells the assembler to generate a warning message if a NOP does not
+ immediately forllow an instruction that enables or disables
+ interrupts. This is the default.
+
+ Note that this option can be stacked with the `-mn' option so that
+ the assembler will both warn about missing NOP instructions and
+ then insert them automatically.
+
+`-mY'
+ disables warnings about missing NOP instructions.
+
+`-md'
+ mark the object file as one that requires data to copied from ROM
+ to RAM at execution startup. Disabled by default.

+
+ Additional built-in macros are:
+
+`llo(exp)'

+
+`lhi(exp)'
+ Extracts most significant word from 32-bit expression 'exp'.
+
+`hlo(exp)'
+ Extracts 3rd word from 64-bit expression 'exp'.
+
+`hhi(exp)'
+ Extracts 4rd word from 64-bit expression 'exp'.

+
+9.29.2.2 Special Characters
+...........................
+
+A semicolon (`;') appearing anywhere on a line starts a comment that
+extends to the end of that line.
+
+ If a `#' appears as the first character of a line then the whole
+line is treated as a comment, but it can also be a logical line number
+directive (*note Comments::) or a preprocessor control command (*note
+Preprocessing::).
+
+ Multiple statements can appear on the same line provided that they
+are separated by the `{' character.
+
+ The character `$' in jump instructions indicates current location and
+implemented only for TI syntax compatibility.

+`0' and `15'. The leading letters may be in either upper or lower
+case; for example, `r13' and `R7' are both valid register names.
+
+ Register names `PC', `SP' and `SR' cannot be used as register names
+and will be treated as variables. Use `r0', `r1', and `r2' instead.

+ `jCOND $+N+2'
+
+
+ Also, there are some instructions, which cannot be found in other
+assemblers. These are branch instructions, which has different opcodes
+upon jump distance. They all got PC relative addressing mode.

+
+`.profiler'
+ This directive instructs assembler to add new profile entry to the
+ object file.
+
+`.refsym'
+ This directive instructs assembler to add an undefined reference to
+ the symbol following the directive. The maximum symbol name
+ length is 1023 characters. No relocation is created for this
+ symbol; it will exist purely for pulling in object files from
+ archives. Note that this reloc is not sufficient to prevent
+ garbage collection; use a KEEP() directive in the linker file to

+
+It is a performance hit to use gcc's profiling approach for this tiny
+target. Even more - jtag hardware facility does not perform any
+profiling functions. However we've got gdb's built-in simulator where
+we can do anything.
+
+ We define new section `.profiler' which holds all profiling
+information. We define new pseudo operation `.profiler' which will
+instruct assembler to add new profile entry to the object file. Profile
+should take place at the present address.
+
+ Pseudo operation format:
+
+ `.profiler flags,function_to_profile [, cycle_corrector, extra]'
+
+ where:
+
+ `flags' is a combination of the following characters:

+
+ If Sequent compatibility has been configured into the assembler then

+9.33.3 PDP-11 Assembly Language Syntax
+--------------------------------------
+
+`as' supports both DEC syntax and BSD syntax. The only difference is
+that in DEC syntax, a `#' character is used to denote an immediate
+constants, while in BSD syntax the character for this purpose is `$'.
+
+ general-purpose registers are named `r0' through `r7'. Mnemonic
+alternatives for `r6' and `r7' are `sp' and `pc', respectively.
+
+ Floating-point registers are named `ac0' through `ac3', or
+alternatively `fr0' through `fr3'.
+
+ Comments are started with a `#' or a `/' character, and extend to
+the end of the line. (FIXME: clash with immediates?)
+
+ Multiple statements on the same line can be separated by the `;'
+character.

+
+9.37.1 RX Options
+-----------------
+
+The Renesas RX port of `as' has a few target specfic command line
+options:
+
+`-m32bit-doubles'
+ This option controls the ABI and indicates to use a 32-bit float
+ ABI. It has no effect on the assembled instructions, but it does
+ influence the behaviour of the `.double' pseudo-op. This is the
+ default.
+
+`-m64bit-doubles'
+ This option controls the ABI and indicates to use a 64-bit float
+ ABI. It has no effect on the assembled instructions, but it does
+ influence the behaviour of the `.double' pseudo-op.
+
+`-mbig-endian'
+ This option controls the ABI and indicates to use a big-endian data
+ ABI. It has no effect on the assembled instructions, but it does
+ influence the behaviour of the `.short', `.hword', `.int',
+ `.word', `.long', `.quad' and `.octa' pseudo-ops.
+
+`-mlittle-endian'
+ This option controls the ABI and indicates to use a little-endian
+ data ABI. It has no effect on the assembled instructions, but it
+ does influence the behaviour of the `.short', `.hword', `.int',
+ `.word', `.long', `.quad' and `.octa' pseudo-ops. This is the
+ default.
+
+`-muse-conventional-section-names'
+ This option controls the default names given to the code (.text),
+ initialised data (.data) and uninitialised data sections (.bss).
+
+`-muse-renesas-section-names'
+ This option controls the default names given to the code (.P),
+ initialised data (.D_1) and uninitialised data sections (.B_1).
+ This is the default.
+
+`-msmall-data-limit'
+ This option tells the assembler that the small data limit feature
+ of the RX port of GCC is being used. This results in the assembler
+ generating an undefined reference to a symbol called `__gp' for
+ use by the relocations that are needed to support the small data
+ limit feature. This option is not enabled by default as it would
+ otherwise pollute the symbol table.
+
+`-mpid'
+ This option tells the assembler that the position independent data
+ of the RX port of GCC is being used. This results in the assembler
+ generating an undefined reference to a symbol called `__pid_base',
+ and also setting the RX_PID flag bit in the e_flags field of the
+ ELF header of the object file.
+
+`-mint-register=NUM'
+ This option tells the assembler how many registers have been
+ reserved for use by interrupt handlers. This is needed in order
+ to compute the correct values for the `%gpreg' and `%pidreg' meta
+ registers.
+
+`-mgcc-abi'
+ This option tells the assembler that the old GCC ABI is being used
+ by the assembled code. With this version of the ABI function
+ arguments that are passed on the stack are aligned to a 32-bit
+ boundary.
+
+`-mrx-abi'
+ This option tells the assembler that the official RX ABI is being
+ used by the assembled code. With this version of the ABI function
+ arguments that are passed on the stack are aligned to their natural
+ alignments. This option is the default.
+
+`-mcpu=NAME'
+ This option tells the assembler the target CPU type. Currently the
+ `rx200', `rx600' and `rx610' are recognised as valid cpu names.
+ Attempting to assemble an instruction not supported by the
+ indicated cpu type will result in an error message being generated.
+

+
+File: as.info, Node: RX-Modifiers, Next: RX-Directives, Prev: RX-Opts, Up: RX-Dependent
+
+9.37.2 Symbolic Operand Modifiers
+---------------------------------
+
+The assembler supports one modifier when using symbol addresses in RX
+instruction operands. The general syntax is the following:
+
+ %gp(symbol)
+
+ The modifier returns the offset from the __GP symbol to the
+specified symbol as a 16-bit value. The intent is that this offset
+should be used in a register+offset move instruction when generating
+references to small data. Ie, like this:
+
+ mov.W %gp(_foo)[%gpreg], r1
+
+ The assembler also supports two meta register names which can be used
+to refer to registers whose values may not be known to the programmer.
+These meta register names are:
+
+`%gpreg'
+ The small data address register.
+
+`%pidreg'
+ The PID base address register.
+
+
+ Both registers normally have the value r13, but this can change if
+some registers have been reserved for use by interrupt handlers or if
+both the small data limit and position independent data features are
+being used at the same time.

+
+9.37.3 Assembler Directives
+---------------------------
+
+The RX version of `as' has the following specific assembler directives:
+
+`.3byte'
+ Inserts a 3-byte value into the output file at the current
+ location.
+
+`.fetchalign'
+ If the next opcode following this directive spans a fetch line
+ boundary (8 byte boundary), the opcode is aligned to that boundary.
+ If the next opcode does not span a fetch line, this directive has
+ no effect. Note that one or more labels may be between this
+ directive and the opcode; those labels are aligned as well. Any
+ inserted bytes due to alignment will form a NOP opcode.

+---------------------
+
+The floating point formats generated by directives are these.
+
+`.float'
+ `Single' precision (32-bit) floating point constants.
+
+`.double'
+ If the `-m64bit-doubles' command line option has been specified
+ then then `double' directive generates `double' precision (64-bit)
+ floating point constants, otherwise it generates `single'
+ precision (32-bit) floating point constants. To force the
+ generation of 64-bit floating point constants used the `dc.d'
+ directive instead.

+
+`-m31 | -m64'
+ Select 31- or 64-bit ABI implying a word size of 32- or 64-bit.
+
+ These options are only available with the ELF object file format,
+ and require that the necessary BFD support has been included (on a
+ 31-bit platform you must add -enable-64-bit-bfd on the call to the
+ configure script to enable 64-bit usage and use s390x as target
+ platform).
+
+`-mesa | -mzarch'
+ Select the architecture mode, either the Enterprise System
+ Architecture (esa) mode or the z/Architecture mode (zarch).
+
+ The 64-bit instructions are only available with the z/Architecture
+ mode. The combination of `-m64' and `-mesa' results in a warning
+ message.
+
+`-march=CPU'
+ This option specifies the target processor. The following
+ processor names are recognized: `g5', `g6', `z900', `z990',
+ `z9-109', `z9-ec', `z10' and `z196'. Assembling an instruction
+ that is not supported on the target processor results in an error
+ message. Do not specify `g5' or `g6' with `-mzarch'.
+
+`-mregnames'
+ Allow symbolic names for registers.
+
+`-mno-regnames'
+ Do not allow symbolic names for registers.
+
+`-mwarn-areg-zero'
+ Warn whenever the operand for a base or index register has been
+ specified but evaluates to zero. This can indicate the misuse of
+ general purpose register 0 as an address register.

+........................
+
+The `as' recognizes a number of predefined symbols for the various
+processor registers. A register specification in one of the instruction
+formats is an unsigned integer between 0 and 15. The specific
+instruction and the position of the register in the instruction format
+denotes the type of the register. The register symbols are prefixed with
+`%':
+
+ %rN the 16 general purpose registers, 0 <= N <= 15
+ %fN the 16 floating point registers, 0 <= N <= 15
+ %aN the 16 access registers, 0 <= N <= 15

+9.38.3.2 Instruction Mnemonics
+..............................
+
+All instructions documented in the Principles of Operation are supported
+with the mnemonic and order of operands as described. The instruction
+mnemonic identifies the instruction format (*Note s390 Formats::) and
+the specific operation code for the instruction. For example, the `lr'
+mnemonic denotes the instruction format `RR' with the operation code
+`0x18'.
+
+ The definition of the various mnemonics follows a scheme, where the
+first character usually hint at the type of the instruction:
+
+ a add instruction, for example `al' for add logical 32-bit
+ b branch instruction, for example `bc' for branch on condition
+ c compare or convert instruction, for example `cr' for compare
+ register 32-bit
+ d divide instruction, for example `dlr' devide logical register
+ 64-bit to 32-bit
+ i insert instruction, for example `ic' insert character
+ l load instruction, for example `ltr' load and test register
+ mv move instruction, for example `mvc' move character
+ m multiply instruction, for example `mh' multiply halfword
+ n and instruction, for example `ni' and immediate
+ o or instruction, for example `oc' or character
+ sla, sll shift left single instruction
+ sra, srl shift right single instruction
+ st store instruction, for example `stm' store multiple
+ s subtract instruction, for example `slr' subtract
+ logical 32-bit
+ t test or translate instruction, of example `tm' test under mask
+ x exclusive or instruction, for example `xc' exclusive or
+ character
+
+ Certain characters at the end of the mnemonic may describe a property
+of the instruction:
+
+ c the instruction uses a 8-bit character operand
+ f the instruction extends a 32-bit operand to 64 bit
+ g the operands are treated as 64-bit values
+ h the operand uses a 16-bit halfword operand
+ i the instruction uses an immediate operand
+ l the instruction uses unsigned, logical operands
+ m the instruction uses a mask or operates on multiple values
+ r if r is the last character, the instruction operates on registers
+ y the instruction uses 20-bit displacements
+
+ There are many exceptions to the scheme outlined in the above lists,
+in particular for the priviledged instructions. For non-priviledged
+instruction it works quite well, for example the instruction `clgfr' c:
+compare instruction, l: unsigned operands, g: 64-bit operands, f: 32-
+to 64-bit extension, r: register operands. The instruction compares an
+64-bit value in a register with the zero extended 32-bit value from a
+second register. For a complete list of all mnemonics see appendix B
+in the Principles of Operation.

+9.38.3.3 Instruction Operands
+.............................
+
+Instruction operands can be grouped into three classes, operands located
+in registers, immediate operands, and operands in storage.
+
+ A register operand can be located in general, floating-point, access,
+or control register. The register is identified by a four-bit field.
+The field containing the register operand is called the R field.
+
+ Immediate operands are contained within the instruction and can have
+8, 16 or 32 bits. The field containing the immediate operand is called
+the I field. Dependent on the instruction the I field is either signed
+or unsigned.
+
+ A storage operand consists of an address and a length. The address
+of a storage operands can be specified in any of these ways:
+
+ * The content of a single general R
+
+ * The sum of the content of a general register called the base
+ register B plus the content of a displacement field D
+
+ * The sum of the contents of two general registers called the index
+ register X and the base register B plus the content of a
+ displacement field
+
+ * The sum of the current instruction address and a 32-bit signed
+ immediate field multiplied by two.
+
+ The length of a storage operand can be:
+
+ * Implied by the instruction
+
+ * Specified by a bitmask
+
+ * Specified by a four-bit or eight-bit length field L
+
+ * Specified by the content of a general register
+
+ The notation for storage operand addresses formed from multiple
+fields is as follows:
+
+`Dn(Bn)'
+ the address for operand number n is formed from the content of
+ general register Bn called the base register and the displacement
+ field Dn.
+
+`Dn(Xn,Bn)'
+ the address for operand number n is formed from the content of
+ general register Xn called the index register, general register Bn
+ called the base register and the displacement field Dn.
+
+`Dn(Ln,Bn)'
+ the address for operand number n is formed from the content of
+ general regiser Bn called the base register and the displacement
+ field Dn. The length of the operand n is specified by the field
+ Ln.
+
+ The base registers Bn and the index registers Xn of a storage
+operand can be skipped. If Bn and Xn are skipped, a zero will be stored
+to the operand field. The notation changes as follows:
+
+ full notation short notation
+ ------------------------------------------
+ Dn(0,Bn) Dn(Bn)
+ Dn(0,0) Dn
+ Dn(0) Dn
+ Dn(Ln,0) Dn(Ln)

+9.38.3.4 Instruction Formats
+............................
+
+The Principles of Operation manuals lists 26 instruction formats where
+some of the formats have multiple variants. For the `.insn' pseudo
+directive the assembler recognizes some of the formats. Typically, the
+most general variant of the instruction format is used by the `.insn'
+directive.
+
+ The following table lists the abbreviations used in the table of
+instruction formats:
+
+ OpCode / OpCd Part of the op code.
+ Bx Base register number for operand x.
+ Dx Displacement for operand x.
+ DLx Displacement lower 12 bits for operand x.
+ DHx Displacement higher 8-bits for operand x.
+ Rx Register number for operand x.
+ Xx Index register number for operand x.
+ Ix Signed immediate for operand x.
+ Ux Unsigned immediate for operand x.
+
+ An instruction is two, four, or six bytes in length and must be
+aligned on a 2 byte boundary. The first two bits of the instruction
+specify the length of the instruction, 00 indicates a two byte
+instruction, 01 and 10 indicates a four byte instruction, and 11
+indicates a six byte instruction.
+
+ The following table lists the s390 instruction formats that are
+available with the `.insn' pseudo directive:

+............................
+
+A specific bit pattern can have multiple mnemonics, for example the bit
+pattern `0xa7000000' has the mnemonics `tmh' and `tmlh'. In addition,
+there are a number of mnemonics recognized by `as' that are not present
+in the Principles of Operation. These are the short forms of the
+branch instructions, where the condition code mask operand is encoded
+in the mnemonic. This is relevant for the branch instructions, the
+compare and branch instructions, and the compare and trap instructions.
+
+ For the branch instructions there are 20 condition code strings that
+can be used as part of the mnemonic in place of a mask operand in the
+instruction format:

+9.38.3.6 Instruction Operand Modifier
+.....................................
+
+If a symbol modifier is attached to a symbol in an expression for an
+instruction operand field, the symbol term is replaced with a reference
+to an object in the global offset table (GOT) or the procedure linkage
+table (PLT). The following expressions are allowed: `symbol@modifier +
+constant', `symbol@modifier + label + constant', and `symbol@modifier -
+label + constant'. The term `symbol' is the symbol that will be
+entered into the GOT or PLT, `label' is a local label, and `constant'
+is an arbitrary expression that the assembler can evaluate to a
+constant value.
+
+ The term `(symbol + constant1)@modifier +/- label + constant2' is
+also accepted but a warning message is printed and the term is
+converted to `symbol@modifier +/- label + constant1 + constant2'.
+
+`@got'
+`@got12'
+ The @got modifier can be used for displacement fields, 16-bit
+ immediate fields and 32-bit pc-relative immediate fields. The
+ @got12 modifier is synonym to @got. The symbol is added to the
+ GOT. For displacement fields and 16-bit immediate fields the
+ symbol term is replaced with the offset from the start of the GOT
+ to the GOT slot for the symbol. For a 32-bit pc-relative field
+ the pc-relative offset to the GOT slot from the current
+ instruction address is used.
+
+`@gotent'
+ The @gotent modifier can be used for 32-bit pc-relative immediate
+ fields. The symbol is added to the GOT and the symbol term is
+ replaced with the pc-relative offset from the current instruction
+ to the GOT slot for the symbol.
+
+`@gotoff'
+ The @gotoff modifier can be used for 16-bit immediate fields. The
+ symbol term is replaced with the offset from the start of the GOT
+ to the address of the symbol.
+
+`@gotplt'
+ The @gotplt modifier can be used for displacement fields, 16-bit
+ immediate fields, and 32-bit pc-relative immediate fields. A
+ procedure linkage table entry is generated for the symbol and a
+ jump slot for the symbol is added to the GOT. For displacement
+ fields and 16-bit immediate fields the symbol term is replaced
+ with the offset from the start of the GOT to the jump slot for the
+ symbol. For a 32-bit pc-relative field the pc-relative offset to
+ the jump slot from the current instruction address is used.
+
+`@plt'
+ The @plt modifier can be used for 16-bit and 32-bit pc-relative
+ immediate fields. A procedure linkage table entry is generated for
+ the symbol. The symbol term is replaced with the relative offset
+ from the current instruction to the PLT entry for the symbol.
+
+`@pltoff'
+ The @pltoff modifier can be used for 16-bit immediate fields. The
+ symbol term is replaced with the offset from the start of the PLT
+ to the address of the symbol.
+
+`@gotntpoff'
+ The @gotntpoff modifier can be used for displacement fields. The
+ symbol is added to the static TLS block and the negated offset to
+ the symbol in the static TLS block is added to the GOT. The symbol
+ term is replaced with the offset to the GOT slot from the start of
+ the GOT.
+
+`@indntpoff'
+ The @indntpoff modifier can be used for 32-bit pc-relative
+ immediate fields. The symbol is added to the static TLS block and
+ the negated offset to the symbol in the static TLS block is added
+ to the GOT. The symbol term is replaced with the pc-relative
+ offset to the GOT slot from the current instruction address.
+
+ For more information about the thread local storage modifiers
+`gotntpoff' and `indntpoff' see the ELF extension documentation `ELF
+Handling For Thread-Local Storage'.

+
+9.38.3.7 Instruction Marker
+...........................
+
+The thread local storage instruction markers are used by the linker to
+perform code optimization.
+
+`:tls_load'
+ The :tls_load marker is used to flag the load instruction in the
+ initial exec TLS model that retrieves the offset from the thread
+ pointer to a thread local storage variable from the GOT.
+
+`:tls_gdcall'
+ The :tls_gdcall marker is used to flag the branch-and-save
+ instruction to the __tls_get_offset function in the global dynamic
+ TLS model.
+
+`:tls_ldcall'
+ The :tls_ldcall marker is used to flag the branch-and-save
+ instruction to the __tls_get_offset function in the local dynamic
+ TLS model.
+
+ For more information about the thread local storage instruction
+marker and the linker optimizations see the ELF extension documentation

+
+9.38.3.8 Literal Pool Entries
+.............................
+
+A literal pool is a collection of values. To access the values a pointer
+to the literal pool is loaded to a register, the literal pool register.
+Usually, register %r13 is used as the literal pool register (*Note s390
+Register::). Literal pool entries are created by adding the suffix
+:lit1, :lit2, :lit4, or :lit8 to the end of an expression for an
+instruction operand. The expression is added to the literal pool and the
+operand is replaced with the offset to the literal in the literal pool.
+
+`:lit1'
+ The literal pool entry is created as an 8-bit value. An operand
+ modifier must not be used for the original expression.
+
+`:lit2'
+ The literal pool entry is created as a 16 bit value. The operand
+ modifier @got may be used in the original expression. The term
+ `x@got:lit2' will put the got offset for the global symbol x to
+ the literal pool as 16 bit value.
+
+`:lit4'
+ The literal pool entry is created as a 32-bit value. The operand
+ modifier @got and @plt may be used in the original expression. The
+ term `x@got:lit4' will put the got offset for the global symbol x
+ to the literal pool as a 32-bit value. The term `x@plt:lit4' will
+ put the plt offset for the global symbol x to the literal pool as
+ a 32-bit value.
+
+`:lit8'
+ The literal pool entry is created as a 64-bit value. The operand
+ modifier @got and @plt may be used in the original expression. The
+ term `x@got:lit8' will put the got offset for the global symbol x
+ to the literal pool as a 64-bit value. The term `x@plt:lit8' will
+ put the plt offset for the global symbol x to the literal pool as
+ a 64-bit value.
+
+ The assembler directive `.ltorg' is used to emit all literal pool
+entries to the current position.

+9.38.4 Assembler Directives
+---------------------------
+
+`as' for s390 supports all of the standard ELF assembler directives as
+outlined in the main part of this document. Some directives have been
+extended and there are some additional directives, which are only
+available for the s390 `as'.
+
+`.insn'
+ This directive permits the numeric representation of an
+ instructions and makes the assembler insert the operands according
+ to one of the instructions formats for `.insn' (*Note s390
+ Formats::). For example, the instruction `l %r1,24(%r15)' could
+ be written as `.insn rx,0x58000000,%r1,24(%r15)'.
+
+`.short'
+`.long'
+`.quad'
+ This directive places one or more 16-bit (.short), 32-bit (.long),
+ or 64-bit (.quad) values into the current section. If an ELF or
+ TLS modifier is used only the following expressions are allowed:
+ `symbol@modifier + constant', `symbol@modifier + label +
+ constant', and `symbol@modifier - label + constant'. The
+ following modifiers are available:
+ `@got'
+ `@got12'
+ The @got modifier can be used for .short, .long and .quad.
+ The @got12 modifier is synonym to @got. The symbol is added
+ to the GOT. The symbol term is replaced with offset from the
+ start of the GOT to the GOT slot for the symbol.
+
+ `@gotoff'
+ The @gotoff modifier can be used for .short, .long and .quad.
+ The symbol term is replaced with the offset from the start of
+ the GOT to the address of the symbol.
+
+ `@gotplt'
+ The @gotplt modifier can be used for .long and .quad. A
+ procedure linkage table entry is generated for the symbol and
+ a jump slot for the symbol is added to the GOT. The symbol
+ term is replaced with the offset from the start of the GOT to
+ the jump slot for the symbol.
+
+ `@plt'
+ The @plt modifier can be used for .long and .quad. A
+ procedure linkage table entry us generated for the symbol.
+ The symbol term is replaced with the address of the PLT entry
+ for the symbol.
+
+ `@pltoff'
+ The @pltoff modifier can be used for .short, .long and .quad.
+ The symbol term is replaced with the offset from the start of
+ the PLT to the address of the symbol.
+
+ `@tlsgd'
+ `@tlsldm'
+ The @tlsgd and @tlsldm modifier can be used for .long and
+ .quad. A tls_index structure for the symbol is added to the
+ GOT. The symbol term is replaced with the offset from the
+ start of the GOT to the tls_index structure.
+
+ `@gotntpoff'
+ `@indntpoff'
+ The @gotntpoff and @indntpoff modifier can be used for .long
+ and .quad. The symbol is added to the static TLS block and
+ the negated offset to the symbol in the static TLS block is
+ added to the GOT. For @gotntpoff the symbol term is replaced
+ with the offset from the start of the GOT to the GOT slot,
+ for @indntpoff the symbol term is replaced with the address
+ of the GOT slot.
+
+ `@dtpoff'
+ The @dtpoff modifier can be used for .long and .quad. The
+ symbol term is replaced with the offset of the symbol
+ relative to the start of the TLS block it is contained in.
+
+ `@ntpoff'
+ The @ntpoff modifier can be used for .long and .quad. The
+ symbol term is replaced with the offset of the symbol
+ relative to the TCB pointer.
+
+ For more information about the thread local storage modifiers see
+ the ELF extension documentation `ELF Handling For Thread-Local
+ Storage'.
+
+`.ltorg'
+ This directive causes the current contents of the literal pool to
+ be dumped to the current location (*Note s390 Literal Pool
+ Entries::).
+
+`.machine string'
+ This directive allows you to change the machine for which code is
+ generated. `string' may be any of the `-march=' selection options
+ (without the -march=), `push', or `pop'. `.machine push' saves
+ the currently selected cpu, which may be restored with `.machine
+ pop'. Be aware that the cpu string has to be put into double
+ quotes in case it contains characters not appropriate for
+ identifiers. So you have to write `"z9-109"' instead of just
+ `z9-109'.
+
+`.machinemode string'
+ This directive allows to change the architecture mode for which
+ code is being generated. `string' may be `esa', `zarch',
+ `zarch_nohighgprs', `push', or `pop'. `.machinemode
+ zarch_nohighgprs' can be used to prevent the `highgprs' flag from
+ being set in the ELF header of the output file. This is useful in
+ situations where the code is gated with a runtime check which
+ makes sure that the code is only executed on kernels providing the
+ `highgprs' feature. `.machinemode push' saves the currently
+ selected mode, which may be restored with `.machinemode pop'.

+control registers.
+
+`RN'
+ Register direct
+
+`@RN'
+ Register indirect
+

+ Register indirect with pre-decrement
+
+`@RN+'
+ Register indirect with post-increment
+

+
+`@(DISP, GBR)'
+ `GBR' offset
+
+`@(R0, GBR)'
+ GBR indexed
+
+`ADDR'
+`@(DISP, PC)'
+ PC relative address (for branch or for addressing memory). The
+ `as' implementation allows you to use the simpler form ADDR
+ anywhere a PC relative address is called for; the alternate form
+ is supported for compatibility with other assemblers.
+
+`#IMM'
+ Immediate data
+
+
+File: as.info, Node: SH Floating Point, Next: SH Directives, Prev: SH Syntax, Up: SH-Dependent
+
+9.40.3 Floating Point
+---------------------
+
+SH2E, SH3E and SH4 groups have on-chip floating-point unit (FPU). Other
+SH groups can use `.float' directive to generate IEEE floating-point
+numbers.
+
+ SH2E and SH3E support single-precision floating point calculations as
+well as entirely PCAPI compatible emulation of double-precision
+floating point calculations. SH2E and SH3E instructions are a subset of
+the floating point calculations conforming to the IEEE754 standard.
+
+ In addition to single-precision and double-precision floating-point
+operation capability, the on-chip FPU of SH4 has a 128-bit graphic
+engine that enables 32-bit floating-point data to be processed 128 bits
+at a time. It also supports 4 * 4 array operations and inner product
+operations. Also, a superscalar architecture is employed that enables
+simultaneous execution of two instructions (including FPU
+instructions), providing performance of up to twice that of
+conventional architectures at the same frequency.

+
+9.40.4 SH Machine Directives
+----------------------------
+
+`uaword'
+`ualong'
+`uaquad'
+ `as' will issue a warning when a misaligned `.word', `.long', or
+ `.quad' directive is used. You may use `.uaword', `.ualong', or
+ `.uaquad' to indicate that the value is intentionally misaligned.

+`SH-Microcomputer User's Manual' (Renesas) or `SH-4 32-bit CPU Core
+Architecture' (SuperH) and `SuperH (SH) 64-Bit RISC Series' (SuperH).
+
+ `as' implements all the standard SH opcodes. No additional
+pseudo-instructions are needed on this family. Note, however, that
+because `as' supports a simpler form of PC-relative addressing, you may
+simply write (for example)
+
+ mov.l bar,r0

+9.41.2.2 Register Names

+
+You can use the predefined symbols `r0' through `r63' to refer to the

+`tr0' through `tr7' for target address registers, `fr0' through `fr63'
+for single-precision floating point registers, `dr0' through `dr62'
+(even numbered registers only) for double-precision floating point
+registers, `fv0' through `fv60' (multiples of four only) for
+single-precision floating point vectors, `fp0' through `fp62' (even
+numbered registers only) for single-precision floating point pairs,
+`mtrx0' through `mtrx48' (multiples of 16 only) for 4x4 matrices of
+single-precision floating point registers, `pc' for the program
+counter, and `fpscr' for the floating point status and control register.
+
+ You can also refer to the control registers by the mnemonics `sr',
+`ssr', `pssr', `intevt', `expevt', `pexpevt', `tra', `spc', `pspc',
+`resvec', `vbr', `tea', `dcr', `kcr0', `kcr1', `ctc', and `usr'.

+File: as.info, Node: SH64-Addressing, Prev: SH64-Regs, Up: SH64 Syntax
+
+9.41.2.3 Addressing Modes
+.........................
+
+SH64 operands consist of either a register or immediate value. The
+immediate value can be a constant or label reference (or portion of a
+label reference), as in this example:
+
+ movi 4,r2
+ pt function, tr4
+ movi (function >> 16) & 65535,r0
+ shori function & 65535, r0
+ ld.l r0,4,r0
+
+ Instruction label references can reference labels in either SHmedia
+or SHcompact. To differentiate between the two, labels in SHmedia
+sections will always have the least significant bit set (i.e. they will
+be odd), which SHcompact labels will have the least significant bit
+reset (i.e. they will be even). If you need to reference the actual
+address of a label, you can use the `datalabel' modifier, as in this
+example:
+
+ .long function
+ .long datalabel function
+
+ In that example, the first longword may or may not have the least
+significant bit set depending on whether the label is an SHmedia label
+or an SHcompact label. The second longword will be the actual address
+of the label, regardless of what type of label it is.

+
+9.41.3 SH64 Machine Directives
+------------------------------
+
+In addition to the SH directives, the SH64 provides the following
+directives:
+
+`.mode [shmedia|shcompact]'
+`.isa [shmedia|shcompact]'
+ Specify the ISA for the following instructions (the two directives
+ are equivalent). Note that programs such as `objdump' rely on
+ symbolic labels to determine when such mode switches occur (by
+ checking the least significant bit of the label's address), so
+ such mode/isa changes should always be followed by a label (in
+ practice, this is true anyway). Note that you cannot use these
+ directives if you didn't specify an ISA on the command line.
+
+`.abi [32|64]'
+ Specify the ABI for the following instructions. Note that you
+ cannot use this directive unless you specified an ABI on the
+ command line, and the ABIs specified must match.

+`SuperH 64 bit RISC Series Architecture Manual' (SuperH, Inc.).

+following pseudo-opcodes may be expanded into one or more alternate
+opcodes:

+`movi'
+ If the value doesn't fit into a standard `movi' opcode, `as' will
+ replace the `movi' with a sequence of `movi' and `shori' opcodes.
+
+`pt'
+ This expands to a sequence of `movi' and `shori' opcode, followed
+ by a `ptrel' opcode, or to a `pta' or `ptb' opcode, depending on
+ the label referenced.

+9.42.1 Options
+--------------
+
+The SPARC chip family includes several successive versions, using the
+same core instruction set, but including a few additional instructions
+at each version. There are exceptions to this however. For details on
+what instructions each variant supports, please see the chip's
+architecture reference manual.
+
+ By default, `as' assumes the core instruction set (SPARC v6), but
+"bumps" the architecture level as needed: it switches to successively
+higher architectures as it encounters instructions that only exist in
+the higher levels.
+
+ If not configured for SPARC v9 (`sparc64-*-*') GAS will not bump
+past sparclite by default, an option must be passed to enable the v9
+instructions.
+
+ GAS treats sparclite as being compatible with v8, unless an
+architecture is explicitly requested. SPARC v9 is always incompatible
+with sparclite.
+
+`-Av6 | -Av7 | -Av8 | -Aleon | -Asparclet | -Asparclite'
+`-Av8plus | -Av8plusa | -Av8plusb | -Av8plusc | -Av8plusd | -Av8plusv'
+`-Av9 | -Av9a | -Av9b | -Av9c | -Av9d | -Av9e | -Av9v | -Av9m'
+`-Asparc | -Asparcvis | -Asparcvis2 | -Asparcfmaf | -Asparcima'
+`-Asparcvis3 | -Asparcvis3r'
+ Use one of the `-A' options to select one of the SPARC
+ architectures explicitly. If you select an architecture
+ explicitly, `as' reports a fatal error if it encounters an
+ instruction or feature requiring an incompatible or higher level.
+
+ `-Av8plus', `-Av8plusa', `-Av8plusb', `-Av8plusc', `-Av8plusd',
+ and `-Av8plusv' select a 32 bit environment.
+
+ `-Av9', `-Av9a', `-Av9b', `-Av9c', `-Av9d', `-Av9e', `-Av9v' and
+ `-Av9m' select a 64 bit environment and are not available unless
+ GAS is explicitly configured with 64 bit environment support.
+
+ `-Av8plusa' and `-Av9a' enable the SPARC V9 instruction set with
+ UltraSPARC VIS 1.0 extensions.
+
+ `-Av8plusb' and `-Av9b' enable the UltraSPARC VIS 2.0 instructions,
+ as well as the instructions enabled by `-Av8plusa' and `-Av9a'.
+
+ `-Av8plusc' and `-Av9c' enable the UltraSPARC Niagara instructions,
+ as well as the instructions enabled by `-Av8plusb' and `-Av9b'.
+
+ `-Av8plusd' and `-Av9d' enable the floating point fused
+ multiply-add, VIS 3.0, and HPC extension instructions, as well as
+ the instructions enabled by `-Av8plusc' and `-Av9c'.
+
+ `-Av8pluse' and `-Av9e' enable the cryptographic instructions, as
+ well as the instructions enabled by `-Av8plusd' and `-Av9d'.
+
+ `-Av8plusv' and `-Av9v' enable floating point unfused
+ multiply-add, and integer multiply-add, as well as the instructions
+ enabled by `-Av8pluse' and `-Av9e'.
+
+ `-Av8plusm' and `-Av9m' enable the VIS 4.0, subtract extended,
+ xmpmul, xmontmul and xmontsqr instructions, as well as the
+ instructions enabled by `-Av8plusv' and `-Av9v'.
+
+ `-Asparc' specifies a v9 environment. It is equivalent to `-Av9'
+ if the word size is 64-bit, and `-Av8plus' otherwise.
+
+ `-Asparcvis' specifies a v9a environment. It is equivalent to
+ `-Av9a' if the word size is 64-bit, and `-Av8plusa' otherwise.
+
+ `-Asparcvis2' specifies a v9b environment. It is equivalent to
+ `-Av9b' if the word size is 64-bit, and `-Av8plusb' otherwise.
+
+ `-Asparcfmaf' specifies a v9b environment with the floating point
+ fused multiply-add instructions enabled.
+
+ `-Asparcima' specifies a v9b environment with the integer

+
+9.42.2 Enforcing aligned data
+-----------------------------
+
+SPARC GAS normally permits data to be misaligned. For example, it
+permits the `.long' pseudo-op to be used on a byte boundary. However,
+the native SunOS assemblers issue an error when they see misaligned
+data.
+
+ You can use the `--enforce-aligned-data' option to make SPARC GAS
+also issue an error about misaligned data, just as the SunOS assemblers
+do.
+
+ The `--enforce-aligned-data' option is not the default because gcc
+issues misaligned data pseudo-ops when it initializes certain packed
+data structures (structures defined using the `packed' attribute). You
+may have to assemble with GAS in order to initialize packed data
+structures in your own code.
+

+
+9.42.3 Sparc Syntax
+-------------------
+
+The assembler syntax closely follows The Sparc Architecture Manual,
+versions 8 and 9, as well as most extensions defined by Sun for their
+UltraSPARC and Niagara line of processors.

+9.42.3.1 Special Characters
+...........................
+
+A `!' character appearing anywhere on a line indicates the start of a
+comment that extends to the end of that line.
+
+ If a `#' appears as the first character of a line then the whole
+line is treated as a comment, but in this case the line could also be a
+logical line number directive (*note Comments::) or a preprocessor
+control command (*note Preprocessing::).
+
+ `;' can be used instead of a newline to separate statements.

+
+9.42.3.2 Register Names
+.......................
+
+The Sparc integer register file is broken down into global, outgoing,
+local, and incoming.
+
+ * The 8 global registers are referred to as `%gN'.
+
+ * The 8 outgoing registers are referred to as `%oN'.
+

+double or quad, and thus only even or quad numbered accesses are
+allowed. For example, `%f34' is a legal floating point register, but
+`%f35' is not.
+
+ Certain V9 instructions allow access to ancillary state registers.
+Most simply they can be referred to as `%asrN' where N can be from 16
+to 31. However, there are some aliases defined to reference ASR
+registers defined for various UltraSPARC processors:
+
+ * The tick compare register is referred to as `%tick_cmpr'.
+
+ * The system tick register is referred to as `%stick'. An alias,
+ `%sys_tick', exists but is deprecated and should not be used by

+ * The V9 dispatch control register is referred to as `%dcr'.
+
+ Various V9 branch and conditional move instructions allow
+specification of which set of integer condition codes to test. These
+are referred to as `%xcc' and `%icc'.
+
+ In V9, there are 4 sets of floating point condition codes which are
+referred to as `%fccN'.

+
+9.42.3.3 Constants
+..................
+
+Several Sparc instructions take an immediate operand field for which
+mnemonic names exist. Two such examples are `membar' and `prefetch'.
+Another example are the set of V9 memory access instruction that allow
+specification of an address space identifier.
+
+ The `membar' instruction specifies a memory barrier that is the
+defined by the operand which is a bitmask. The supported mask
+mnemonics are:
+
+ * `#Sync' requests that all operations (including nonmemory
+ reference operations) appearing prior to the `membar' must have
+ been performed and the effects of any exceptions become visible
+ before any instructions after the `membar' may be initiated. This
+ corresponds to `membar' cmask field bit 2.
+
+ * `#MemIssue' requests that all memory reference operations
+ appearing prior to the `membar' must have been performed before
+ any memory operation after the `membar' may be initiated. This
+ corresponds to `membar' cmask field bit 1.
+
+ * `#Lookaside' requests that a store appearing prior to the `membar'
+ must complete before any load following the `membar' referencing
+ the same address can be initiated. This corresponds to `membar'
+ cmask field bit 0.
+
+ * `#StoreStore' defines that the effects of all stores appearing
+ prior to the `membar' instruction must be visible to all
+ processors before the effect of any stores following the `membar'.
+ Equivalent to the deprecated `stbar' instruction. This
+ corresponds to `membar' mmask field bit 3.
+
+ * `#LoadStore' defines all loads appearing prior to the `membar'
+ instruction must have been performed before the effect of any
+ stores following the `membar' is visible to any other processor.
+ This corresponds to `membar' mmask field bit 2.
+
+ * `#StoreLoad' defines that the effects of all stores appearing
+ prior to the `membar' instruction must be visible to all
+ processors before loads following the `membar' may be performed.
+ This corresponds to `membar' mmask field bit 1.
+
+ * `#LoadLoad' defines that all loads appearing prior to the `membar'
+ instruction must have been performed before any loads following
+ the `membar' may be performed. This corresponds to `membar' mmask
+ field bit 0.
+
+
+ These values can be ored together, for example:
+
+ membar #Sync
+ membar #StoreLoad | #LoadLoad
+ membar #StoreLoad | #StoreStore
+
+ The `prefetch' and `prefetcha' instructions take a prefetch function
+code. The following prefetch function code constant mnemonics are
+available:
+
+ * `#n_reads' requests a prefetch for several reads, and corresponds
+ to a prefetch function code of 0.
+
+ `#one_read' requests a prefetch for one read, and corresponds to a
+ prefetch function code of 1.
+
+ `#n_writes' requests a prefetch for several writes (and possibly
+ reads), and corresponds to a prefetch function code of 2.
+
+ `#one_write' requests a prefetch for one write, and corresponds to
+ a prefetch function code of 3.
+
+ `#page' requests a prefetch page, and corresponds to a prefetch
+ function code of 4.
+
+ `#invalidate' requests a prefetch invalidate, and corresponds to a
+ prefetch function code of 16.
+
+ `#unified' requests a prefetch to the nearest unified cache, and
+ corresponds to a prefetch function code of 17.
+
+ `#n_reads_strong' requests a strong prefetch for several reads,
+ and corresponds to a prefetch function code of 20.
+
+ `#one_read_strong' requests a strong prefetch for one read, and
+ corresponds to a prefetch function code of 21.
+
+ `#n_writes_strong' requests a strong prefetch for several writes,
+ and corresponds to a prefetch function code of 22.
+
+ `#one_write_strong' requests a strong prefetch for one write, and
+ corresponds to a prefetch function code of 23.
+
+ Onle one prefetch code may be specified. Here are some examples:
+
+ prefetch [%l0 + %l2], #one_read
+ prefetch [%g2 + 8], #n_writes
+ prefetcha [%g1] 0x8, #unified
+ prefetcha [%o0 + 0x10] %asi, #n_reads
+
+ The actual behavior of a given prefetch function code is processor
+ specific. If a processor does not implement a given prefetch
+ function code, it will treat the prefetch instruction as a nop.
+
+ For instructions that accept an immediate address space identifier,
+ `as' provides many mnemonics corresponding to V9 defined as well
+ as UltraSPARC and Niagara extended values. For example, `#ASI_P'
+ and `#ASI_BLK_INIT_QUAD_LDD_AIUS'. See the V9 and processor
+ specific manuals for details.

+
+9.42.3.4 Relocations
+....................
+
+ELF relocations are available as defined in the 32-bit and 64-bit Sparc
+ELF specifications.
+
+ `R_SPARC_HI22' is obtained using `%hi' and `R_SPARC_LO10' is
+obtained using `%lo'. Likewise `R_SPARC_HIX22' is obtained from `%hix'
+and `R_SPARC_LOX10' is obtained using `%lox'. For example:
+
+ sethi %hi(symbol), %g1
+ or %g1, %lo(symbol), %g1
+
+ sethi %hix(symbol), %g1
+ xor %g1, %lox(symbol), %g1
+
+ These "high" mnemonics extract bits 31:10 of their operand, and the
+"low" mnemonics extract bits 9:0 of their operand.
+
+ V9 code model relocations can be requested as follows:
+
+ * `R_SPARC_HH22' is requested using `%hh'. It can also be generated
+ using `%uhi'.
+
+ * `R_SPARC_HM10' is requested using `%hm'. It can also be generated
+ using `%ulo'.
+
+ * `R_SPARC_LM22' is requested using `%lm'.
+
+ * `R_SPARC_H44' is requested using `%h44'.
+
+ * `R_SPARC_M44' is requested using `%m44'.
+
+ * `R_SPARC_L44' is requested using `%l44' or `%l34'.
+
+ * `R_SPARC_H34' is requested using `%h34'.
+
+ The `%l34' generates a `R_SPARC_L44' relocation because it
+calculates the necessary value, and therefore no explicit `R_SPARC_L34'
+relocation needed to be created for this purpose.
+
+ The `%h34' and `%l34' relocations are used for the abs34 code model.
+Here is an example abs34 address generation sequence:
+
+ sethi %h34(symbol), %g1
+ sllx %g1, 2, %g1
+ or %g1, %l34(symbol), %g1
+
+ The PC relative relocation `R_SPARC_PC22' can be obtained by
+enclosing an operand inside of `%pc22'. Likewise, the `R_SPARC_PC10'
+relocation can be obtained using `%pc10'. These are mostly used when
+assembling PIC code. For example, the standard PIC sequence on Sparc
+to get the base of the global offset table, PC relative, into a
+register, can be performed as:
+
+ sethi %pc22(_GLOBAL_OFFSET_TABLE_-4), %l7
+ add %l7, %pc10(_GLOBAL_OFFSET_TABLE_+4), %l7
+
+ Several relocations exist to allow the link editor to potentially
+optimize GOT data references. The `R_SPARC_GOTDATA_OP_HIX22'
+relocation can obtained by enclosing an operand inside of
+`%gdop_hix22'. The `R_SPARC_GOTDATA_OP_LOX10' relocation can obtained
+by enclosing an operand inside of `%gdop_lox10'. Likewise,
+`R_SPARC_GOTDATA_OP' can be obtained by enclosing an operand inside of
+`%gdop'. For example, assuming the GOT base is in register `%l7':
+
+ sethi %gdop_hix22(symbol), %l1
+ xor %l1, %gdop_lox10(symbol), %l1
+ ld [%l7 + %l1], %l2, %gdop(symbol)
+
+ There are many relocations that can be requested for access to
+thread local storage variables. All of the Sparc TLS mnemonics are
+supported:
+
+ * `R_SPARC_TLS_GD_HI22' is requested using `%tgd_hi22'.
+
+ * `R_SPARC_TLS_GD_LO10' is requested using `%tgd_lo10'.
+
+ * `R_SPARC_TLS_GD_ADD' is requested using `%tgd_add'.
+
+ * `R_SPARC_TLS_GD_CALL' is requested using `%tgd_call'.
+
+ * `R_SPARC_TLS_LDM_HI22' is requested using `%tldm_hi22'.
+
+ * `R_SPARC_TLS_LDM_LO10' is requested using `%tldm_lo10'.
+
+ * `R_SPARC_TLS_LDM_ADD' is requested using `%tldm_add'.
+
+ * `R_SPARC_TLS_LDM_CALL' is requested using `%tldm_call'.
+
+ * `R_SPARC_TLS_LDO_HIX22' is requested using `%tldo_hix22'.
+
+ * `R_SPARC_TLS_LDO_LOX10' is requested using `%tldo_lox10'.
+
+ * `R_SPARC_TLS_LDO_ADD' is requested using `%tldo_add'.
+
+ * `R_SPARC_TLS_IE_HI22' is requested using `%tie_hi22'.
+
+ * `R_SPARC_TLS_IE_LO10' is requested using `%tie_lo10'.
+
+ * `R_SPARC_TLS_IE_LD' is requested using `%tie_ld'.
+
+ * `R_SPARC_TLS_IE_LDX' is requested using `%tie_ldx'.
+
+ * `R_SPARC_TLS_IE_ADD' is requested using `%tie_add'.
+
+ * `R_SPARC_TLS_LE_HIX22' is requested using `%tle_hix22'.
+
+ * `R_SPARC_TLS_LE_LOX10' is requested using `%tle_lox10'.
+
+ Here are some example TLS model sequences.
+
+ First, General Dynamic:

+
+ Initial Exec:

+ ld [%l7 + %l1], %o0, %tie_ld(symbol)
+ add %g7, %o0, %o0, %tie_add(symbol)
+
+ sethi %tie_hi22(symbol), %l1

+ ldx [%l7 + %l1], %o0, %tie_ldx(symbol)
+ add %g7, %o0, %o0, %tie_add(symbol)
+
+ And finally, Local Exec:
+
+ sethi %tle_hix22(symbol), %l1
+ add %l1, %tle_lox10(symbol), %l1
+ add %g7, %l1, %l1
+
+ When assembling for 64-bit, and a secondary constant addend is
+specified in an address expression that would normally generate an
+`R_SPARC_LO10' relocation, the assembler will emit an `R_SPARC_OLO10'
+instead.

+`as' provides support for this via operand size opcode translations.
+Translations are supported for loads, stores, shifts, compare-and-swap
+atomics, and the `clr' synthetic instruction.
+
+ If generating 32-bit code, `as' will generate the 32-bit opcode.
+Whereas if 64-bit code is being generated, the 64-bit opcode will be
+emitted. For example `ldn' will be transformed into `ld' for 32-bit
+code and `ldx' for 64-bit code.
+
+ Here is an example meant to demonstrate all the supported opcode
+translations:
+
+ ldn [%o0], %o1
+ ldna [%o0] %asi, %o2
+ stn %o1, [%o0]
+ stna %o2, [%o0] %asi
+ slln %o3, 3, %o3
+ srln %o4, 8, %o4
+ sran %o5, 12, %o5
+ casn [%o0], %o1, %o2
+ casna [%o0] %asi, %o1, %o2
+ clrn %g1
+
+ In 32-bit mode `as' will emit:
+
+ ld [%o0], %o1
+ lda [%o0] %asi, %o2
+ st %o1, [%o0]
+ sta %o2, [%o0] %asi
+ sll %o3, 3, %o3
+ srl %o4, 8, %o4
+ sra %o5, 12, %o5
+ cas [%o0], %o1, %o2
+ casa [%o0] %asi, %o1, %o2
+ clr %g1
+
+ And in 64-bit mode `as' will emit:
+
+ ldx [%o0], %o1
+ ldxa [%o0] %asi, %o2
+ stx %o1, [%o0]
+ stxa %o2, [%o0] %asi
+ sllx %o3, 3, %o3
+ srlx %o4, 8, %o4
+ srax %o5, 12, %o5
+ casx [%o0], %o1, %o2
+ casxa [%o0] %asi, %o1, %o2
+ clrx %g1
+
+ Finally, the `.nword' translating directive is supported as well.
+It is documented in the section on Sparc machine directives.

+
+File: as.info, Node: Sparc-Directives, Prev: Sparc-Float, Up: Sparc-Dependent
+
+9.42.5 Sparc Machine Directives
+-------------------------------
+
+The Sparc version of `as' supports the following additional machine
+directives:
+
+`.align'
+ This must be followed by the desired alignment in bytes.
+
+`.common'
+ This must be followed by a symbol name, a positive number, and
+ `"bss"'. This behaves somewhat like `.comm', but the syntax is
+ different.
+
+`.half'
+ This is functionally identical to `.short'.
+
+`.nword'
+ On the Sparc, the `.nword' directive produces native word sized
+ value, ie. if assembling with -32 it is equivalent to `.word', if
+ assembling with -64 it is equivalent to `.xword'.
+
+`.proc'
+ This directive is ignored. Any text following it on the same line
+ is also ignored.
+
+`.register'
+ This directive declares use of a global application or system
+ register. It must be followed by a register name %g2, %g3, %g6 or
+ %g7, comma and the symbol name for that register. If symbol name
+ is `#scratch', it is a scratch register, if it is `#ignore', it
+ just suppresses any errors about using undeclared global register,
+ but does not emit any information about it into the object file.
+ This can be useful e.g. if you save the register before use and
+ restore it after.
+
+`.reserve'
+ This must be followed by a symbol name, a positive number, and
+ `"bss"'. This behaves somewhat like `.lcomm', but the syntax is
+ different.
+
+`.seg'
+ This must be followed by `"text"', `"data"', or `"data1"'. It
+ behaves like `.text', `.data', or `.data 1'.
+
+`.skip'
+ This is functionally identical to the `.space' directive.
+
+`.word'
+ On the Sparc, the `.word' directive produces 32 bit values,
+ instead of the 16 bit values it produces on many other machines.
+
+`.xword'
+ On the Sparc V9 processor, the `.xword' directive produces 64 bit
+ values.

+
+9.43.1 Options
+--------------
+
+The TMS320C54X version of `as' has a few machine-dependent options.
+
+ You can use the `-mfar-mode' option to enable extended addressing
+mode. All addresses will be assumed to be > 16 bits, and the
+appropriate relocation types will be used. This option is equivalent
+to using the `.far_mode' directive in the assembly code. If you do not
+use the `-mfar-mode' option, all references will be assumed to be 16
+bits. This option may be abbreviated to `-mf'.
+
+ You can use the `-mcpu' option to specify a particular CPU. This
+option is equivalent to using the `.version' directive in the assembly
+code. For recognized CPU codes, see *Note `.version':
+TIC54X-Directives. The default CPU version is `542'.
+
+ You can use the `-merrors-to-file' option to redirect error output
+to a file (this provided for those deficient environments which don't
+provide adequate output redirection). This option may be abbreviated to
+`-me'.

+
+9.43.2 Blocking
+---------------
+
+A blocked section or memory block is guaranteed not to cross the
+blocking boundary (usually a page, or 128 words) if it is smaller than
+the blocking size, or to start on a page boundary if it is larger than
+the blocking size.

+
+9.43.3 Environment Settings
+---------------------------
+
+`C54XDSP_DIR' and `A_DIR' are semicolon-separated paths which are added
+to the list of directories normally searched for source and include
+files. `C54XDSP_DIR' will override `A_DIR'.

+
+9.43.4 Constants Syntax
+-----------------------
+
+The TIC54X version of `as' allows the following additional constant
+formats, using a suffix to indicate the radix:
+
+ Binary `000000B, 011000b'
+ Octal `10Q, 224q'
+ Hexadecimal `45h, 0FH'
+
+
+File: as.info, Node: TIC54X-Subsyms, Next: TIC54X-Locals, Prev: TIC54X-Constants, Up: TIC54X-Dependent
+
+9.43.5 String Substitution
+--------------------------
+
+A subset of allowable symbols (which we'll call subsyms) may be assigned
+arbitrary string values. This is roughly equivalent to C preprocessor
+#define macros. When `as' encounters one of these symbols, the symbol
+is replaced in the input stream by its string value. Subsym names
+*must* begin with a letter.
+
+ Subsyms may be defined using the `.asg' and `.eval' directives
+(*Note `.asg': TIC54X-Directives, *Note `.eval': TIC54X-Directives.
+
+ Expansion is recursive until a previously encountered symbol is
+seen, at which point substitution stops.
+
+ In this example, x is replaced with SYM2; SYM2 is replaced with
+SYM1, and SYM1 is replaced with x. At this point, x has already been
+encountered and the substitution stops.
+
+ .asg "x",SYM1
+ .asg "SYM1",SYM2
+ .asg "SYM2",x
+ add x,a ; final code assembled is "add x, a"
+
+ Macro parameters are converted to subsyms; a side effect of this is
+the normal `as' '\ARG' dereferencing syntax is unnecessary. Subsyms
+defined within a macro will have global scope, unless the `.var'
+directive is used to identify the subsym as a local macro variable
+*note `.var': TIC54X-Directives.
+
+ Substitution may be forced in situations where replacement might be
+ambiguous by placing colons on either side of the subsym. The following
+code:
+
+ .eval "10",x
+ LAB:X: add #x, a
+
+ When assembled becomes:
+
+ LAB10 add #10, a
+
+ Smaller parts of the string assigned to a subsym may be accessed with
+the following syntax:
+
+``:SYMBOL(CHAR_INDEX):''
+ Evaluates to a single-character string, the character at
+ CHAR_INDEX.
+
+``:SYMBOL(START,LENGTH):''
+ Evaluates to a substring of SYMBOL beginning at START with length
+ LENGTH.

+
+9.43.6 Local Labels
+-------------------
+
+Local labels may be defined in two ways:
+
+ * $N, where N is a decimal number between 0 and 9
+
+ * LABEL?, where LABEL is any legal symbol name.
+
+ Local labels thus defined may be redefined or automatically
+generated. The scope of a local label is based on when it may be
+undefined or reset. This happens when one of the following situations
+is encountered:
+
+ * .newblock directive *note `.newblock': TIC54X-Directives.
+
+ * The current section is changed (.sect, .text, or .data)
+
+ * Entering or leaving an included file
+
+ * The macro scope where the label was defined is exited

+9.43.8 Extended Addressing
+--------------------------
+
+The `LDX' pseudo-op is provided for loading the extended addressing bits
+of a label or address. For example, if an address `_label' resides in
+extended program memory, the value of `_label' may be loaded as follows:
+ ldx #_label,16,a ; loads extended bits of _label
+ or #_label,a ; loads lower 16 bits of _label
+ bacc a ; full address is in accumulator A

+
+9.43.9 Directives
+-----------------
+
+`.align [SIZE]'
+`.even'
+ Align the section program counter on the next boundary, based on
+ SIZE. SIZE may be any power of 2. `.even' is equivalent to
+ `.align' with a SIZE of 2.
+ `1'
+ Align SPC to word boundary
+
+ `2'
+ Align SPC to longword boundary (same as .even)
+
+ `128'
+ Align SPC to page boundary
+
+`.asg STRING, NAME'
+ Assign NAME the string STRING. String replacement is performed on
+ STRING before assignment.
+
+`.eval STRING, NAME'
+ Evaluate the contents of string STRING and assign the result as a
+ string to the subsym NAME. String replacement is performed on
+ STRING before assignment.
+
+`.bss SYMBOL, SIZE [, [BLOCKING_FLAG] [,ALIGNMENT_FLAG]]'
+ Reserve space for SYMBOL in the .bss section. SIZE is in words.
+ If present, BLOCKING_FLAG indicates the allocated space should be
+ aligned on a page boundary if it would otherwise cross a page
+ boundary. If present, ALIGNMENT_FLAG causes the assembler to
+ allocate SIZE on a long word boundary.
+
+`.byte VALUE [,...,VALUE_N]'
+`.ubyte VALUE [,...,VALUE_N]'
+`.char VALUE [,...,VALUE_N]'
+`.uchar VALUE [,...,VALUE_N]'
+ Place one or more bytes into consecutive words of the current
+ section. The upper 8 bits of each word is zero-filled. If a
+ label is used, it points to the word allocated for the first byte
+ encountered.
+
+`.clink ["SECTION_NAME"]'
+ Set STYP_CLINK flag for this section, which indicates to the
+ linker that if no symbols from this section are referenced, the
+ section should not be included in the link. If SECTION_NAME is
+ omitted, the current section is used.
+
+`.c_mode'
+ TBD.
+
+`.copy "FILENAME" | FILENAME'
+`.include "FILENAME" | FILENAME'
+ Read source statements from FILENAME. The normal include search
+ path is used. Normally .copy will cause statements from the
+ included file to be printed in the assembly listing and .include
+ will not, but this distinction is not currently implemented.
+
+`.data'
+ Begin assembling code into the .data section.
+
+`.double VALUE [,...,VALUE_N]'
+`.ldouble VALUE [,...,VALUE_N]'
+`.float VALUE [,...,VALUE_N]'
+`.xfloat VALUE [,...,VALUE_N]'
+ Place an IEEE single-precision floating-point representation of
+ one or more floating-point values into the current section. All
+ but `.xfloat' align the result on a longword boundary. Values are
+ stored most-significant word first.
+
+`.drlist'
+`.drnolist'
+ Control printing of directives to the listing file. Ignored.
+
+`.emsg STRING'
+`.mmsg STRING'
+`.wmsg STRING'
+ Emit a user-defined error, message, or warning, respectively.
+
+`.far_mode'
+ Use extended addressing when assembling statements. This should
+ appear only once per file, and is equivalent to the -mfar-mode
+ option *note `-mfar-mode': TIC54X-Opts.
+
+`.fclist'
+`.fcnolist'
+ Control printing of false conditional blocks to the listing file.
+
+`.field VALUE [,SIZE]'
+ Initialize a bitfield of SIZE bits in the current section. If
+ VALUE is relocatable, then SIZE must be 16. SIZE defaults to 16
+ bits. If VALUE does not fit into SIZE bits, the value will be
+ truncated. Successive `.field' directives will pack starting at
+ the current word, filling the most significant bits first, and
+ aligning to the start of the next word if the field size does not
+ fit into the space remaining in the current word. A `.align'
+ directive with an operand of 1 will force the next `.field'
+ directive to begin packing into a new word. If a label is used, it
+ points to the word that contains the specified field.
+
+`.global SYMBOL [,...,SYMBOL_N]'
+`.def SYMBOL [,...,SYMBOL_N]'
+`.ref SYMBOL [,...,SYMBOL_N]'
+ `.def' nominally identifies a symbol defined in the current file
+ and available to other files. `.ref' identifies a symbol used in
+ the current file but defined elsewhere. Both map to the standard
+ `.global' directive.
+
+`.half VALUE [,...,VALUE_N]'
+`.uhalf VALUE [,...,VALUE_N]'
+`.short VALUE [,...,VALUE_N]'
+`.ushort VALUE [,...,VALUE_N]'
+`.int VALUE [,...,VALUE_N]'
+`.uint VALUE [,...,VALUE_N]'
+`.word VALUE [,...,VALUE_N]'
+`.uword VALUE [,...,VALUE_N]'
+ Place one or more values into consecutive words of the current
+ section. If a label is used, it points to the word allocated for
+ the first value encountered.
+
+`.label SYMBOL'
+ Define a special SYMBOL to refer to the load time address of the
+ current section program counter.
+
+`.length'
+`.width'
+ Set the page length and width of the output listing file. Ignored.
+
+`.list'
+`.nolist'
+ Control whether the source listing is printed. Ignored.
+
+`.long VALUE [,...,VALUE_N]'
+`.ulong VALUE [,...,VALUE_N]'
+`.xlong VALUE [,...,VALUE_N]'
+ Place one or more 32-bit values into consecutive words in the
+ current section. The most significant word is stored first.
+ `.long' and `.ulong' align the result on a longword boundary;
+ `xlong' does not.
+
+`.loop [COUNT]'
+`.break [CONDITION]'
+`.endloop'
+ Repeatedly assemble a block of code. `.loop' begins the block, and
+ `.endloop' marks its termination. COUNT defaults to 1024, and
+ indicates the number of times the block should be repeated.
+ `.break' terminates the loop so that assembly begins after the
+ `.endloop' directive. The optional CONDITION will cause the loop
+ to terminate only if it evaluates to zero.
+
+`MACRO_NAME .macro [PARAM1][,...PARAM_N]'
+`[.mexit]'
+`.endm'
+ See the section on macros for more explanation (*Note
+ TIC54X-Macros::.
+
+`.mlib "FILENAME" | FILENAME'
+ Load the macro library FILENAME. FILENAME must be an archived
+ library (BFD ar-compatible) of text files, expected to contain
+ only macro definitions. The standard include search path is used.
+
+`.mlist'
+`.mnolist'
+ Control whether to include macro and loop block expansions in the
+ listing output. Ignored.
+
+`.mmregs'
+ Define global symbolic names for the 'c54x registers. Supposedly
+ equivalent to executing `.set' directives for each register with
+ its memory-mapped value, but in reality is provided only for
+ compatibility and does nothing.
+
+`.newblock'
+ This directive resets any TIC54X local labels currently defined.
+ Normal `as' local labels are unaffected.
+
+`.option OPTION_LIST'
+ Set listing options. Ignored.
+
+`.sblock "SECTION_NAME" | SECTION_NAME [,"NAME_N" | NAME_N]'
+ Designate SECTION_NAME for blocking. Blocking guarantees that a
+ section will start on a page boundary (128 words) if it would
+ otherwise cross a page boundary. Only initialized sections may be
+ designated with this directive. See also *Note TIC54X-Block::.
+
+`.sect "SECTION_NAME"'
+ Define a named initialized section and make it the current section.
+
+`SYMBOL .set "VALUE"'
+`SYMBOL .equ "VALUE"'
+ Equate a constant VALUE to a SYMBOL, which is placed in the symbol
+ table. SYMBOL may not be previously defined.
+
+`.space SIZE_IN_BITS'
+`.bes SIZE_IN_BITS'
+ Reserve the given number of bits in the current section and
+ zero-fill them. If a label is used with `.space', it points to the
+ *first* word reserved. With `.bes', the label points to the
+ *last* word reserved.
+
+`.sslist'
+`.ssnolist'
+ Controls the inclusion of subsym replacement in the listing
+ output. Ignored.
+
+`.string "STRING" [,...,"STRING_N"]'
+`.pstring "STRING" [,...,"STRING_N"]'
+ Place 8-bit characters from STRING into the current section.
+ `.string' zero-fills the upper 8 bits of each word, while
+ `.pstring' puts two characters into each word, filling the
+ most-significant bits first. Unused space is zero-filled. If a
+ label is used, it points to the first word initialized.
+
+`[STAG] .struct [OFFSET]'
+`[NAME_1] element [COUNT_1]'
+`[NAME_2] element [COUNT_2]'
+`[TNAME] .tag STAGX [TCOUNT]'
+`...'
+`[NAME_N] element [COUNT_N]'
+`[SSIZE] .endstruct'
+`LABEL .tag [STAG]'
+ Assign symbolic offsets to the elements of a structure. STAG
+ defines a symbol to use to reference the structure. OFFSET
+ indicates a starting value to use for the first element
+ encountered; otherwise it defaults to zero. Each element can have
+ a named offset, NAME, which is a symbol assigned the value of the
+ element's offset into the structure. If STAG is missing, these
+ become global symbols. COUNT adjusts the offset that many times,
+ as if `element' were an array. `element' may be one of `.byte',
+ `.word', `.long', `.float', or any equivalent of those, and the
+ structure offset is adjusted accordingly. `.field' and `.string'
+ are also allowed; the size of `.field' is one bit, and `.string'
+ is considered to be one word in size. Only element descriptors,
+ structure/union tags, `.align' and conditional assembly directives
+ are allowed within `.struct'/`.endstruct'. `.align' aligns member
+ offsets to word boundaries only. SSIZE, if provided, will always
+ be assigned the size of the structure.
+
+ The `.tag' directive, in addition to being used to define a
+ structure/union element within a structure, may be used to apply a
+ structure to a symbol. Once applied to LABEL, the individual
+ structure elements may be applied to LABEL to produce the desired
+ offsets using LABEL as the structure base.
+
+`.tab'
+ Set the tab size in the output listing. Ignored.
+
+`[UTAG] .union'
+`[NAME_1] element [COUNT_1]'
+`[NAME_2] element [COUNT_2]'
+`[TNAME] .tag UTAGX[,TCOUNT]'
+`...'
+`[NAME_N] element [COUNT_N]'
+`[USIZE] .endstruct'
+`LABEL .tag [UTAG]'
+ Similar to `.struct', but the offset after each element is reset to
+ zero, and the USIZE is set to the maximum of all defined elements.
+ Starting offset for the union is always zero.
+
+`[SYMBOL] .usect "SECTION_NAME", SIZE, [,[BLOCKING_FLAG] [,ALIGNMENT_FLAG]]'
+ Reserve space for variables in a named, uninitialized section
+ (similar to .bss). `.usect' allows definitions sections
+ independent of .bss. SYMBOL points to the first location reserved
+ by this allocation. The symbol may be used as a variable name.
+ SIZE is the allocated size in words. BLOCKING_FLAG indicates
+ whether to block this section on a page boundary (128 words)
+ (*note TIC54X-Block::). ALIGNMENT FLAG indicates whether the
+ section should be longword-aligned.
+
+`.var SYM[,..., SYM_N]'
+ Define a subsym to be a local variable within a macro. See *Note
+ TIC54X-Macros::.
+
+`.version VERSION'
+ Set which processor to build instructions for. Though the
+ following values are accepted, the op is ignored.
+ `541'
+ `542'

+9.43.10 Macros
+--------------
+
+Macros do not require explicit dereferencing of arguments (i.e., \ARG).
+
+ During macro expansion, the macro parameters are converted to
+subsyms. If the number of arguments passed the macro invocation
+exceeds the number of parameters defined, the last parameter is
+assigned the string equivalent of all remaining arguments. If fewer
+arguments are given than parameters, the missing parameters are
+assigned empty strings. To include a comma in an argument, you must
+enclose the argument in quotes.
+
+ The following built-in subsym functions allow examination of the
+string value of subsyms (or ordinary strings). The arguments are
+strings unless otherwise indicated (subsyms passed as args will be
+replaced by the strings they represent).
+``$symlen(STR)''
+ Returns the length of STR.
+
+``$symcmp(STR1,STR2)''
+ Returns 0 if STR1 == STR2, non-zero otherwise.
+
+``$firstch(STR,CH)''
+ Returns index of the first occurrence of character constant CH in
+ STR.
+
+``$lastch(STR,CH)''
+ Returns index of the last occurrence of character constant CH in
+ STR.
+
+``$isdefed(SYMBOL)''
+ Returns zero if the symbol SYMBOL is not in the symbol table,
+ non-zero otherwise.

+9.44.1 TIC6X Options
+--------------------
+
+`-march=ARCH'
+ Enable (only) instructions from architecture ARCH. By default,
+ all instructions are permitted.
+
+ The following values of ARCH are accepted: `c62x', `c64x',
+ `c64x+', `c67x', `c67x+', `c674x'.
+
+`-mdsbt'
+`-mno-dsbt'
+ The `-mdsbt' option causes the assembler to generate the
+ `Tag_ABI_DSBT' attribute with a value of 1, indicating that the
+ code is using DSBT addressing. The `-mno-dsbt' option, the
+ default, causes the tag to have a value of 0, indicating that the
+ code does not use DSBT addressing. The linker will emit a warning
+ if objects of different type (DSBT and non-DSBT) are linked
+ together.
+
+`-mpid=no'
+`-mpid=near'
+`-mpid=far'
+ The `-mpid=' option causes the assembler to generate the
+ `Tag_ABI_PID' attribute with a value indicating the form of data
+ addressing used by the code. `-mpid=no', the default, indicates
+ position-dependent data addressing, `-mpid=near' indicates
+ position-independent addressing with GOT accesses using near DP
+ addressing, and `-mpid=far' indicates position-independent
+ addressing with GOT accesses using far DP addressing. The linker
+ will emit a warning if objects built with different settings of
+ this option are linked together.
+
+`-mpic'
+`-mno-pic'
+ The `-mpic' option causes the assembler to generate the
+ `Tag_ABI_PIC' attribute with a value of 1, indicating that the
+ code is using position-independent code addressing, The
+ `-mno-pic' option, the default, causes the tag to have a value of
+ 0, indicating position-dependent code addressing. The linker will
+ emit a warning if objects of different type (position-dependent and
+ position-independent) are linked together.
+
+`-mbig-endian'
+`-mlittle-endian'
+ Generate code for the specified endianness. The default is
+ little-endian.

+
+9.44.2 TIC6X Syntax
+-------------------
+
+The presence of a `;' on a line indicates the start of a comment that
+extends to the end of the current line. If a `#' or `*' appears as the
+first character of a line, the whole line is treated as a comment.
+Note that if a line starts with a `#' character then it can also be a
+logical line number directive (*note Comments::) or a preprocessor
+control command (*note Preprocessing::).
+
+ The `@' character can be used instead of a newline to separate
+statements.
+
+ Instruction, register and functional unit names are case-insensitive.
+`as' requires fully-specified functional unit names, such as `.S1',
+`.L1X' or `.D1T2', on all instructions using a functional unit.
+
+ For some instructions, there may be syntactic ambiguity between
+register or functional unit names and the names of labels or other
+symbols. To avoid this, enclose the ambiguous symbol name in
+parentheses; register and functional unit names may not be enclosed in
+parentheses.

+
+9.44.3 TIC6X Directives
+-----------------------
+
+Directives controlling the set of instructions accepted by the
+assembler have effect for instructions between the directive and any
+subsequent directive overriding it.
+
+`.arch ARCH'
+ This has the same effect as `-march=ARCH'.
+
+`.cantunwind'
+ Prevents unwinding through the current function. No personality
+ routine or exception table data is required or permitted.
+
+ If this is not specified then frame unwinding information will be
+ constructed from CFI directives. *note CFI directives::.
+
+`.c6xabi_attribute TAG, VALUE'
+ Set the C6000 EABI build attribute TAG to VALUE.
+
+ The TAG is either an attribute number or one of `Tag_ISA',
+ `Tag_ABI_wchar_t', `Tag_ABI_stack_align_needed',
+ `Tag_ABI_stack_align_preserved', `Tag_ABI_DSBT', `Tag_ABI_PID',
+ `Tag_ABI_PIC', `TAG_ABI_array_object_alignment',
+ `TAG_ABI_array_object_align_expected', `Tag_ABI_compatibility' and
+ `Tag_ABI_conformance'. The VALUE is either a `number',
+ `"string"', or `number, "string"' depending on the tag.
+
+`.ehtype SYMBOL'
+ Output an exception type table reference to SYMBOL.
+
+`.endp'
+ Marks the end of and exception table or function. If preceeded by
+ a `.handlerdata' directive then this also switched back to the
+ previous text section.
+
+`.handlerdata'
+ Marks the end of the current function, and the start of the
+ exception table entry for that function. Anything between this
+ directive and the `.endp' directive will be added to the exception
+ table entry.
+
+ Must be preceded by a CFI block containing a `.cfi_lsda' directive.
+
+`.nocmp'
+ Disallow use of C64x+ compact instructions in the current text
+ section.
+
+`.personalityindex INDEX'
+ Sets the personality routine for the current function to the ABI
+ specified compact routine number INDEX
+
+`.personality NAME'
+ Sets the personality routine for the current function to NAME.
+
+`.scomm SYMBOL, SIZE, ALIGN'
+ Like `.comm', creating a common symbol SYMBOL with size SIZE and
+ alignment ALIGN, but unlike when using `.comm', this symbol will
+ be placed into the small BSS section by the linker.

+
+ Instructions consist of a leading opcode or macro name followed by
+whitespace and an optional comma-separated list of operands:
+
+ OPCODE [OPERAND, ...]
+
+ Instructions must be separated by a newline or semicolon.
+
+ There are two ways to write code: either write naked instructions,
+which the assembler is free to combine into VLIW bundles, or specify
+the VLIW bundles explicitly.
+
+ Bundles are specified using curly braces:
+
+ { ADD r3,r4,r5 ; ADD r7,r8,r9 ; LW r10,r11 }
+
+ A bundle can span multiple lines. If you want to put multiple
+instructions on a line, whether in a bundle or not, you need to
+separate them with semicolons as in this example.
+
+ A bundle may contain one or more instructions, up to the limit
+specified by the ISA (currently three). If fewer instructions are
+specified than the hardware supports in a bundle, the assembler inserts
+`fnop' instructions automatically.
+
+ The assembler will prefer to preserve the ordering of instructions
+within the bundle, putting the first instruction in a lower-numbered
+pipeline than the next one, etc. This fact, combined with the optional
+use of explicit `fnop' or `nop' instructions, allows precise control
+over which pipeline executes each instruction.
+
+ If the instructions cannot be bundled in the listed order, the
+assembler will automatically try to find a valid pipeline assignment.
+If there is no way to bundle the instructions together, the assembler
+reports an error.
+
+ The assembler does not yet auto-bundle (automatically combine
+multiple instructions into one bundle), but it reserves the right to do
+so in the future. If you want to force an instruction to run by
+itself, put it in a bundle explicitly with curly braces and use `nop'
+instructions (not `fnop') to fill the remaining pipeline slots in that
+bundle.

+
+9.45.2.3 Symbolic Operand Modifiers
+...................................
+
+The assembler supports several modifiers when using symbol addresses in
+TILE-Gx instruction operands. The general syntax is the following:
+
+ modifier(symbol)
+
+ The following modifiers are supported:
+
+`hw0'
+ This modifier is used to load bits 0-15 of the symbol's address.
+
+`hw1'
+ This modifier is used to load bits 16-31 of the symbol's address.
+
+`hw2'
+ This modifier is used to load bits 32-47 of the symbol's address.
+
+`hw3'
+ This modifier is used to load bits 48-63 of the symbol's address.
+
+`hw0_last'
+ This modifier yields the same value as `hw0', but it also checks
+ that the value does not overflow.
+
+`hw1_last'
+ This modifier yields the same value as `hw1', but it also checks
+ that the value does not overflow.
+
+`hw2_last'
+ This modifier yields the same value as `hw2', but it also checks
+ that the value does not overflow.
+
+ A 48-bit symbolic value is constructed by using the following
+ idiom:
+
+ moveli r0, hw2_last(sym)
+ shl16insli r0, r0, hw1(sym)
+ shl16insli r0, r0, hw0(sym)
+
+`hw0_got'
+ This modifier is used to load bits 0-15 of the symbol's offset in
+ the GOT entry corresponding to the symbol.
+
+`hw0_last_got'
+ This modifier yields the same value as `hw0_got', but it also
+ checks that the value does not overflow.
+
+`hw1_last_got'
+ This modifier is used to load bits 16-31 of the symbol's offset in
+ the GOT entry corresponding to the symbol, and it also checks that
+ the value does not overflow.
+
+`plt'
+ This modifier is used for function symbols. It causes a
+ _procedure linkage table_, an array of code stubs, to be created
+ at the time the shared object is created or linked against,
+ together with a global offset table entry. The value is a
+ pc-relative offset to the corresponding stub code in the procedure
+ linkage table. This arrangement causes the run-time symbol
+ resolver to be called to look up and set the value of the symbol
+ the first time the function is called (at latest; depending
+ environment variables). It is only safe to leave the symbol
+ unresolved this way if all references are function calls.
+
+`hw0_plt'
+ This modifier is used to load bits 0-15 of the pc-relative address
+ of a plt entry.
+
+`hw1_plt'
+ This modifier is used to load bits 16-31 of the pc-relative
+ address of a plt entry.
+
+`hw1_last_plt'
+ This modifier yields the same value as `hw1_plt', but it also
+ checks that the value does not overflow.
+
+`hw2_last_plt'
+ This modifier is used to load bits 32-47 of the pc-relative
+ address of a plt entry, and it also checks that the value does not
+ overflow.
+
+`hw0_tls_gd'
+ This modifier is used to load bits 0-15 of the offset of the GOT
+ entry of the symbol's TLS descriptor, to be used for
+ general-dynamic TLS accesses.
+
+`hw0_last_tls_gd'
+ This modifier yields the same value as `hw0_tls_gd', but it also
+ checks that the value does not overflow.
+
+`hw1_last_tls_gd'
+ This modifier is used to load bits 16-31 of the offset of the GOT
+ entry of the symbol's TLS descriptor, to be used for
+ general-dynamic TLS accesses. It also checks that the value does
+ not overflow.
+
+`hw0_tls_ie'
+ This modifier is used to load bits 0-15 of the offset of the GOT
+ entry containing the offset of the symbol's address from the TCB,
+ to be used for initial-exec TLS accesses.
+
+`hw0_last_tls_ie'
+ This modifier yields the same value as `hw0_tls_ie', but it also
+ checks that the value does not overflow.
+
+`hw1_last_tls_ie'
+ This modifier is used to load bits 16-31 of the offset of the GOT
+ entry containing the offset of the symbol's address from the TCB,
+ to be used for initial-exec TLS accesses. It also checks that the
+ value does not overflow.
+
+`hw0_tls_le'
+ This modifier is used to load bits 0-15 of the offset of the
+ symbol's address from the TCB, to be used for local-exec TLS
+ accesses.
+
+`hw0_last_tls_le'
+ This modifier yields the same value as `hw0_tls_le', but it also
+ checks that the value does not overflow.
+
+`hw1_last_tls_le'
+ This modifier is used to load bits 16-31 of the offset of the
+ symbol's address from the TCB, to be used for local-exec TLS
+ accesses. It also checks that the value does not overflow.
+
+`tls_gd_call'
+ This modifier is used to tag an instrution as the "call" part of a
+ calling sequence for a TLS GD reference of its operand.
+
+`tls_gd_add'
+ This modifier is used to tag an instruction as the "add" part of a
+ calling sequence for a TLS GD reference of its operand.
+
+`tls_ie_load'
+ This modifier is used to tag an instruction as the "load" part of a
+ calling sequence for a TLS IE reference of its operand.

+9.46.2.3 Symbolic Operand Modifiers
+...................................
+
+The assembler supports several modifiers when using symbol addresses in
+TILEPro instruction operands. The general syntax is the following:
+
+ modifier(symbol)
+
+ The following modifiers are supported:
+
+`lo16'
+ This modifier is used to load the low 16 bits of the symbol's
+ address, sign-extended to a 32-bit value (sign-extension allows it
+ to be range-checked against signed 16 bit immediate operands
+ without complaint).
+
+`hi16'
+ This modifier is used to load the high 16 bits of the symbol's
+ address, also sign-extended to a 32-bit value.
+
+`ha16'
+ `ha16(N)' is identical to `hi16(N)', except if `lo16(N)' is
+ negative it adds one to the `hi16(N)' value. This way `lo16' and
+ `ha16' can be added to create any 32-bit value using `auli'. For
+ example, here is how you move an arbitrary 32-bit address into r3:
+
+ moveli r3, lo16(sym)
+ auli r3, r3, ha16(sym)
+
+`got'
+ This modifier is used to load the offset of the GOT entry
+ corresponding to the symbol.
+
+`got_lo16'
+ This modifier is used to load the sign-extended low 16 bits of the
+ offset of the GOT entry corresponding to the symbol.
+
+`got_hi16'
+ This modifier is used to load the sign-extended high 16 bits of the
+ offset of the GOT entry corresponding to the symbol.
+
+`got_ha16'
+ This modifier is like `got_hi16', but it adds one if `got_lo16' of
+ the input value is negative.
+
+`plt'
+ This modifier is used for function symbols. It causes a
+ _procedure linkage table_, an array of code stubs, to be created
+ at the time the shared object is created or linked against,
+ together with a global offset table entry. The value is a
+ pc-relative offset to the corresponding stub code in the procedure
+ linkage table. This arrangement causes the run-time symbol
+ resolver to be called to look up and set the value of the symbol
+ the first time the function is called (at latest; depending
+ environment variables). It is only safe to leave the symbol
+ unresolved this way if all references are function calls.
+
+`tls_gd'
+ This modifier is used to load the offset of the GOT entry of the
+ symbol's TLS descriptor, to be used for general-dynamic TLS
+ accesses.
+
+`tls_gd_lo16'
+ This modifier is used to load the sign-extended low 16 bits of the
+ offset of the GOT entry of the symbol's TLS descriptor, to be used
+ for general dynamic TLS accesses.
+
+`tls_gd_hi16'
+ This modifier is used to load the sign-extended high 16 bits of the
+ offset of the GOT entry of the symbol's TLS descriptor, to be used
+ for general dynamic TLS accesses.
+
+`tls_gd_ha16'
+ This modifier is like `tls_gd_hi16', but it adds one to the value
+ if `tls_gd_lo16' of the input value is negative.
+
+`tls_ie'
+ This modifier is used to load the offset of the GOT entry
+ containing the offset of the symbol's address from the TCB, to be
+ used for initial-exec TLS accesses.
+
+`tls_ie_lo16'
+ This modifier is used to load the low 16 bits of the offset of the
+ GOT entry containing the offset of the symbol's address from the
+ TCB, to be used for initial-exec TLS accesses.
+
+`tls_ie_hi16'
+ This modifier is used to load the high 16 bits of the offset of the
+ GOT entry containing the offset of the symbol's address from the
+ TCB, to be used for initial-exec TLS accesses.
+
+`tls_ie_ha16'
+ This modifier is like `tls_ie_hi16', but it adds one to the value
+ if `tls_ie_lo16' of the input value is negative.

+
+9.47.1 Options
+--------------
+
+The Zilog Z80 and Ascii R800 version of `as' have a few machine
+dependent options.
+`-z80'
+ Produce code for the Z80 processor. There are additional options to
+ request warnings and error messages for undocumented instructions.
+
+`-ignore-undocumented-instructions'
+`-Wnud'
+ Silently assemble undocumented Z80-instructions that have been
+ adopted as documented R800-instructions.
+
+`-ignore-unportable-instructions'
+`-Wnup'
+ Silently assemble all undocumented Z80-instructions.
+
+`-warn-undocumented-instructions'
+`-Wud'
+ Issue warnings for undocumented Z80-instructions that work on
+ R800, do not assemble other undocumented instructions without
+ warning.
+
+`-warn-unportable-instructions'
+`-Wup'
+ Issue warnings for other undocumented Z80-instructions, do not
+ treat any undocumented instructions as errors.
+
+`-forbid-undocumented-instructions'
+`-Fud'
+ Treat all undocumented z80-instructions as errors.
+
+`-forbid-unportable-instructions'
+`-Fup'
+ Treat undocumented z80-instructions that do not work on R800 as
+ errors.
+
+`-r800'
+ Produce code for the R800 processor. The assembler does not support
+ undocumented instructions for the R800. In line with common
+ practice, `as' uses Z80 instruction names for the R800 processor,
+ as far as they exist.

+
+9.47.2 Syntax
+-------------
+
+The assembler syntax closely follows the 'Z80 family CPU User Manual' by
+Zilog. In expressions a single `=' may be used as "is equal to"
+comparison operator.
+
+ Suffices can be used to indicate the radix of integer constants; `H'
+or `h' for hexadecimal, `D' or `d' for decimal, `Q', `O', `q' or `o'
+for octal, and `B' for binary.
+
+ The suffix `b' denotes a backreference to local label.

+
+File: as.info, Node: Z80-Chars, Next: Z80-Regs, Up: Z80 Syntax
+
+9.47.2.1 Special Characters
+...........................
+
+The semicolon `;' is the line comment character;
+
+ If a `#' appears as the first character of a line then the whole
+line is treated as a comment, but in this case the line could also be a
+logical line number directive (*note Comments::) or a preprocessor
+control command (*note Preprocessing::).
+
+ The Z80 assembler does not support a line separator character.
+
+ The dollar sign `$' can be used as a prefix for hexadecimal numbers
+and as a symbol denoting the current location counter.
+
+ A backslash `\' is an ordinary character for the Z80 assembler.
+
+ The single quote `'' must be followed by a closing quote. If there
+is one character in between, it is a character constant, otherwise it is
+a string constant.
+
+
+File: as.info, Node: Z80-Regs, Next: Z80-Case, Prev: Z80-Chars, Up: Z80 Syntax
+
+9.47.2.2 Register Names
+.......................
+
+The registers are referred to with the letters assigned to them by
+Zilog. In addition `as' recognizes `ixl' and `ixh' as the least and
+most significant octet in `ix', and similarly `iyl' and `iyh' as parts
+of `iy'.
+
+
+File: as.info, Node: Z80-Case, Prev: Z80-Regs, Up: Z80 Syntax
+
+9.47.2.3 Case Sensitivity
+.........................
+
+Upper and lower case are equivalent in register names, opcodes,
+condition codes and assembler directives. The case of letters is
+significant in labels and symbol names. The case is also important to
+distinguish the suffix `b' for a backward reference to a local label
+from the suffix `B' for a number in binary notation.

+
+Floating-point numbers are not supported.

+File: as.info, Node: Z80 Directives, Next: Z80 Opcodes, Prev: Z80 Floating Point, Up: Z80-Dependent
+
+9.47.4 Z80 Assembler Directives
+-------------------------------
+
+`as' for the Z80 supports some additional directives for compatibility
+with other assemblers.
+
+ These are the additional directives in `as' for the Z80:
+
+`db EXPRESSION|STRING[,EXPRESSION|STRING...]'
+`defb EXPRESSION|STRING[,EXPRESSION|STRING...]'
+ For each STRING the characters are copied to the object file, for
+ each other EXPRESSION the value is stored in one byte. A warning
+ is issued in case of an overflow.
+
+`dw EXPRESSION[,EXPRESSION...]'
+`defw EXPRESSION[,EXPRESSION...]'
+ For each EXPRESSION the value is stored in two bytes, ignoring
+ overflow.
+
+`d24 EXPRESSION[,EXPRESSION...]'
+`def24 EXPRESSION[,EXPRESSION...]'
+ For each EXPRESSION the value is stored in three bytes, ignoring
+ overflow.
+
+`d32 EXPRESSION[,EXPRESSION...]'
+`def32 EXPRESSION[,EXPRESSION...]'
+ For each EXPRESSION the value is stored in four bytes, ignoring
+ overflow.
+
+`ds COUNT[, VALUE]'
+`defs COUNT[, VALUE]'
+ Fill COUNT bytes in the object file with VALUE, if VALUE is
+ omitted it defaults to zero.
+
+`SYMBOL equ EXPRESSION'
+`SYMBOL defl EXPRESSION'
+ These directives set the value of SYMBOL to EXPRESSION. If `equ'
+ is used, it is an error if SYMBOL is already defined. Symbols
+ defined with `equ' are not protected from redefinition.
+
+`set'
+ This is a normal instruction on Z80, and not an assembler
+ directive.
+
+`psect NAME'
+ A synonym for *Note Section::, no second argument should be given.
+
+
+
+File: as.info, Node: Z80 Opcodes, Prev: Z80 Directives, Up: Z80-Dependent
+
+9.47.5 Opcodes
+--------------
+
+In line with common practice, Z80 mnemonics are used for both the Z80
+and the R800.
+
+ In many instructions it is possible to use one of the half index
+registers (`ixl',`ixh',`iyl',`iyh') in stead of an 8-bit general
+purpose register. This yields instructions that are documented on the
+R800 and undocumented on the Z80. Similarly `in f,(c)' is documented
+on the R800 and undocumented on the Z80.
+
+ The assembler also supports the following undocumented
+Z80-instructions, that have not been adopted in the R800 instruction
+set:
+`out (c),0'
+ Sends zero to the port pointed to by register c.
+
+`sli M'
+ Equivalent to `M = (M<<1)+1', the operand M can be any operand
+ that is valid for `sla'. One can use `sll' as a synonym for `sli'.
+
+`OP (ix+D), R'
+ This is equivalent to
+
+ ld R, (ix+D)
+ OPC R
+ ld (ix+D), R
+
+ The operation `OPC' may be any of `res B,', `set B,', `rl', `rlc',
+ `rr', `rrc', `sla', `sli', `sra' and `srl', and the register `R'
+ may be any of `a', `b', `c', `d', `e', `h' and `l'.
+
+`OPC (iy+D), R'
+ As above, but with `iy' instead of `ix'.
+
+ The web site at `http://www.z80.info' is a good starting place to
+find more information on programming the Z80.

+9.48 Z8000 Dependent Features
+=============================
+
+ The Z8000 as supports both members of the Z8000 family: the
+unsegmented Z8002, with 16 bit addresses, and the segmented Z8001 with
+24 bit addresses.
+
+ When the assembler is in unsegmented mode (specified with the
+`unsegm' directive), an address takes up one word (16 bit) sized
+register. When the assembler is in segmented mode (specified with the
+`segm' directive), a 24-bit address takes up a long (32 bit) register.

+
+The Z8000 has sixteen 16 bit registers, numbered 0 to 15. You can refer
+to different sized groups of registers by register number, with the
+prefix `r' for 16 bit registers, `rr' for 32 bit registers and `rq' for
+64 bit registers. You can also refer to the contents of the first
+eight (of the sixteen 16 bit registers) by bytes. They are named `rlN'
+and `rhN'.

+ Direct: the 16 bit or 24 bit address (depending on whether the
+ assembler is in segmented or unsegmented mode) of the operand is
+ in the instruction.
+
+`address(rN)'
+ Indexed: the 16 or 24 bit address is added to the 16 bit register
+ to produce the final address in memory of the operand.
+
+`rN(#IMM)'
+`rrN(#IMM)'
+ Base Address: the 16 or 24 bit register is added to the 16 bit sign
+ extended immediate displacement to produce the final address in
+ memory of the operand.
+
+`rN(rM)'
+`rrN(rM)'
+ Base Index: the 16 or 24 bit register rN or rrN is added to the

+9.48.3 Assembler Directives for the Z8000
+-----------------------------------------
+
+The Z8000 port of as includes additional assembler directives, for
+compatibility with other Z8000 assemblers. These do not begin with `.'
+(unlike the ordinary as directives).
+
+`segm'
+`.z8001'
+ Generate code for the segmented Z8001.

+`unsegm'
+`.z8002'
+ Generate code for the unsegmented Z8002.

+
+`lval'
+ Synonym for `.long'
+
+`bval'
+ Synonym for `.byte'
+
+`sval'
+ Assemble a string. `sval' expects one string literal, delimited by
+ single quotes. It assembles each byte of the string into
+ consecutive addresses. You can use the escape sequence `%XX'
+ (where XX represents a two-digit hexadecimal number) to represent
+ the character whose ASCII value is XX. Use this feature to
+ describe single quote and other characters that may not appear in
+ string literals as themselves. For example, the C statement
+ `char *a = "he said \"it's 50% off\"";' is represented in Z8000
+ assembly language (shown with the assembler output in hex at the
+ left) as

+
+9.49.1 VAX Command-Line Options
+-------------------------------
+
+The Vax version of `as' accepts any of the following options, gives a
+warning message that the option was ignored and proceeds. These
+options are for compatibility with scripts designed for other people's
+assemblers.
+
+``-D' (Debug)'
+``-S' (Symbol Table)'
+``-T' (Token Trace)'
+ These are obsolete options used to debug old assemblers.
+
+``-d' (Displacement size for JUMPs)'
+ This option expects a number following the `-d'. Like options
+ that expect filenames, the number may immediately follow the `-d'
+ (old standard) or constitute the whole of the command line
+ argument that follows `-d' (GNU standard).
+
+``-V' (Virtualize Interpass Temporary File)'
+ Some other assemblers use a temporary file. This option commanded
+ them to keep the information in active memory rather than in a
+ disk file. `as' always does this, so this option is redundant.
+
+``-J' (JUMPify Longer Branches)'
+ Many 32-bit computers permit a variety of branch instructions to
+ do the same job. Some of these instructions are short (and fast)
+ but have a limited range; others are long (and slow) but can
+ branch anywhere in virtual memory. Often there are 3 flavors of
+ branch: short, medium and long. Some other assemblers would emit
+ short and medium branches, unless told by this option to emit
+ short and long branches.
+
+``-t' (Temporary File Directory)'
+ Some other assemblers may use a temporary file, and this option
+ takes a filename being the directory to site the temporary file.
+ Since `as' does not use a temporary disk file, this option makes
+ no difference. `-t' needs exactly one filename.
+
+ The Vax version of the assembler accepts additional options when
+compiled for VMS:
+
+`-h N'
+ External symbol or section (used for global variables) names are
+ not case sensitive on VAX/VMS and always mapped to upper case.
+ This is contrary to the C language definition which explicitly
+ distinguishes upper and lower case. To implement a standard
+ conforming C compiler, names must be changed (mapped) to preserve
+ the case information. The default mapping is to convert all lower
+ case characters to uppercase and adding an underscore followed by
+ a 6 digit hex value, representing a 24 digit binary value. The
+ one digits in the binary value represent which characters are
+ uppercase in the original symbol name.
+
+ The `-h N' option determines how we map names. This takes several
+ values. No `-h' switch at all allows case hacking as described
+ above. A value of zero (`-h0') implies names should be upper
+ case, and inhibits the case hack. A value of 2 (`-h2') implies
+ names should be all lower case, with no case hack. A value of 3
+ (`-h3') implies that case should be preserved. The value 1 is
+ unused. The `-H' option directs `as' to display every mapped
+ symbol during assembly.
+
+ Symbols whose names include a dollar sign `$' are exceptions to the
+ general name mapping. These symbols are normally only used to
+ reference VMS library names. Such symbols are always mapped to
+ upper case.
+
+`-+'
+ The `-+' option causes `as' to truncate any symbol name larger
+ than 31 characters. The `-+' option also prevents some code
+ following the `_main' symbol normally added to make the object
+ file compatible with Vax-11 "C".
+
+`-1'
+ This option is ignored for backward compatibility with `as'
+ version 1.x.
+
+`-H'
+ The `-H' option causes `as' to print every symbol which was
+ changed by case mapping.

+
+9.49.2 VAX Floating Point
+-------------------------
+
+Conversion of flonums to floating point is correct, and compatible with
+previous assemblers. Rounding is towards zero if the remainder is
+exactly half the least significant bit.
+
+ `D', `F', `G' and `H' floating point formats are understood.
+
+ Immediate floating literals (_e.g._ `S`$6.9') are rendered
+correctly. Again, rounding is towards zero in the boundary case.
+
+ The `.float' directive produces `f' format numbers. The `.double'
+directive produces `d' format numbers.
+
+
+File: as.info, Node: VAX-directives, Next: VAX-opcodes, Prev: VAX-float, Up: Vax-Dependent
+
+9.49.3 Vax Machine Directives
+-----------------------------
+
+The Vax version of the assembler supports four directives for
+generating Vax floating point constants. They are described in the
+table below.
+
+`.dfloat'
+ This expects zero or more flonums, separated by commas, and
+ assembles Vax `d' format 64-bit floating point constants.
+
+`.ffloat'
+ This expects zero or more flonums, separated by commas, and
+ assembles Vax `f' format 32-bit floating point constants.
+
+`.gfloat'
+ This expects zero or more flonums, separated by commas, and
+ assembles Vax `g' format 64-bit floating point constants.
+
+`.hfloat'
+ This expects zero or more flonums, separated by commas, and
+ assembles Vax `h' format 128-bit floating point constants.

+
+9.49.4 VAX Opcodes
+------------------
+
+All DEC mnemonics are supported. Beware that `case...' instructions
+have exactly 3 operands. The dispatch table that follows the `case...'
+instruction should be made with `.word' statements. This is compatible
+with all unix assemblers we know of.
+
+
+File: as.info, Node: VAX-branch, Next: VAX-operands, Prev: VAX-opcodes, Up: Vax-Dependent
+
+9.49.5 VAX Branch Improvement
+-----------------------------
+
+Certain pseudo opcodes are permitted. They are for branch
+instructions. They expand to the shortest branch instruction that
+reaches the target. Generally these mnemonics are made by substituting
+`j' for `b' at the start of a DEC mnemonic. This feature is included
+both for compatibility and to help compilers. If you do not need this
+feature, avoid these opcodes. Here are the mnemonics, and the code
+they can expand into.
+
+`jbsb'
+ `Jsb' is already an instruction mnemonic, so we chose `jbsb'.
+ (byte displacement)
+ `bsbb ...'
+
+ (word displacement)
+ `bsbw ...'
+
+ (long displacement)
+ `jsb ...'
+
+`jbr'
+`jr'
+ Unconditional branch.
+ (byte displacement)
+ `brb ...'
+
+ (word displacement)
+ `brw ...'
+
+ (long displacement)
+ `jmp ...'
+
+`jCOND'
+ COND may be any one of the conditional branches `neq', `nequ',
+ `eql', `eqlu', `gtr', `geq', `lss', `gtru', `lequ', `vc', `vs',
+ `gequ', `cc', `lssu', `cs'. COND may also be one of the bit tests
+ `bs', `bc', `bss', `bcs', `bsc', `bcc', `bssi', `bcci', `lbs',
+ `lbc'. NOTCOND is the opposite condition to COND.
+ (byte displacement)
+ `bCOND ...'
+
+ (word displacement)
+ `bNOTCOND foo ; brw ... ; foo:'
+
+ (long displacement)
+ `bNOTCOND foo ; jmp ... ; foo:'
+
+`jacbX'
+ X may be one of `b d f g h l w'.
+ (word displacement)
+ `OPCODE ...'
+
+ (long displacement)
+ OPCODE ..., foo ;
+ brb bar ;
+ foo: jmp ... ;

+9.49.6 VAX Operands
+-------------------
+
+The immediate character is `$' for Unix compatibility, not `#' as DEC
+writes it.
+
+ The indirect character is `*' for Unix compatibility, not `@' as DEC
+writes it.
+
+ The displacement sizing character is ``' (an accent grave) for Unix
+compatibility, not `^' as DEC writes it. The letter preceding ``' may
+have either case. `G' is not understood, but all other letters (`b i l
+s w') are understood.
+
+ Register names understood are `r0 r1 r2 ... r15 ap fp sp pc'. Upper
+and lower case letters are equivalent.
+
+ For instance
+ tstb *w`$4(r5)
+
+ Any expression is permitted in an operand. Operands are comma
+separated.

+V850 processor family:
+
+`-wsigned_overflow'
+ Causes warnings to be produced when signed immediate values
+ overflow the space available for then within their opcodes. By
+ default this option is disabled as it is possible to receive
+ spurious warnings due to using exact bit patterns as immediate
+ constants.
+
+`-wunsigned_overflow'
+ Causes warnings to be produced when unsigned immediate values
+ overflow the space available for then within their opcodes. By

+
+`-mv850'
+ Specifies that the assembled code should be marked as being
+ targeted at the V850 processor. This allows the linker to detect
+ attempts to link such code with code assembled for other
+ processors.
+
+`-mv850e'
+ Specifies that the assembled code should be marked as being
+ targeted at the V850E processor. This allows the linker to detect
+ attempts to link such code with code assembled for other
+ processors.
+
+`-mv850e1'
+ Specifies that the assembled code should be marked as being
+ targeted at the V850E1 processor. This allows the linker to
+ detect attempts to link such code with code assembled for other
+ processors.
+
+`-mv850any'
+ Specifies that the assembled code should be marked as being
+ targeted at the V850 processor but support instructions that are
+ specific to the extended variants of the process. This allows the
+ production of binaries that contain target specific code, but
+ which are also intended to be used in a generic fashion. For
+ example libgcc.a contains generic routines used by the code
+ produced by GCC for all versions of the v850 architecture,
+ together with support routines only used by the V850E architecture.
+
+`-mv850e2'
+ Specifies that the assembled code should be marked as being
+ targeted at the V850E2 processor. This allows the linker to
+ detect attempts to link such code with code assembled for other
+ processors.
+
+`-mv850e2v3'

+ processors.
+
+`-mv850e2v4'
+ This is an alias for `-mv850e3v5'.
+
+`-mv850e3v5'
+ Specifies that the assembled code should be marked as being
+ targeted at the V850E3V5 processor. This allows the linker to
+ detect attempts to link such code with code assembled for other

+
+`-mrelax'
+ Enables relaxation. This allows the .longcall and .longjump pseudo
+ ops to be used in the assembler source code. These ops label
+ sections of code which are either a long function call or a long
+ branch. The assembler will then flag these sections of code and
+ the linker will attempt to relax them.
+
+`-mgcc-abi'
+ Marks the generated objecy file as supporting the old GCC ABI.
+
+`-mrh850-abi'
+ Marks the generated objecy file as supporting the RH850 ABI. This
+ is the default.
+
+`-m8byte-align'
+ Marks the generated objecy file as supporting a maximum 64-bits of
+ alignment for variables defined in the source code.
+
+`-m4byte-align'
+ Marks the generated objecy file as supporting a maximum 32-bits of

+9.50.5 Opcodes
+--------------
+
+`as' implements all the standard V850 opcodes.
+
+ `as' also implements the following pseudo ops:
+
+`hi0()'
+ Computes the higher 16 bits of the given expression and stores it
+ into the immediate operand field of the given instruction. For
+ example:
+
+ `mulhi hi0(here - there), r5, r6'
+
+ computes the difference between the address of labels 'here' and
+ 'there', takes the upper 16 bits of this difference, shifts it
+ down 16 bits and then multiplies it by the lower 16 bits in
+ register 5, putting the result into register 6.
+
+`lo()'
+ Computes the lower 16 bits of the given expression and stores it
+ into the immediate operand field of the given instruction. For
+ example:
+
+ `addi lo(here - there), r5, r6'
+
+ computes the difference between the address of labels 'here' and
+ 'there', takes the lower 16 bits of this difference and adds it to
+ register 5, putting the result into register 6.
+
+`hi()'
+ Computes the higher 16 bits of the given expression and then adds
+ the value of the most significant bit of the lower 16 bits of the
+ expression and stores the result into the immediate operand field
+ of the given instruction. For example the following code can be
+ used to compute the address of the label 'here' and store it into
+ register 6:
+
+ `movhi hi(here), r0, r6' `movea lo(here), r6, r6'
+
+ The reason for this special behaviour is that movea performs a sign
+ extension on its immediate operand. So for example if the address
+ of 'here' was 0xFFFFFFFF then without the special behaviour of the
+ hi() pseudo-op the movhi instruction would put 0xFFFF0000 into r6,
+ then the movea instruction would takes its immediate operand,
+ 0xFFFF, sign extend it to 32 bits, 0xFFFFFFFF, and then add it
+ into r6 giving 0xFFFEFFFF which is wrong (the fifth nibble is E).
+ With the hi() pseudo op adding in the top bit of the lo() pseudo
+ op, the movhi instruction actually stores 0 into r6 (0xFFFF + 1 =
+ 0x0000), so that the movea instruction stores 0xFFFFFFFF into r6 -
+ the right value.
+
+`hilo()'
+ Computes the 32 bit value of the given expression and stores it
+ into the immediate operand field of the given instruction (which
+ must be a mov instruction). For example:
+
+ `mov hilo(here), r6'
+
+ computes the absolute address of label 'here' and puts the result
+ into register 6.
+
+`sdaoff()'
+ Computes the offset of the named variable from the start of the
+ Small Data Area (whoes address is held in register 4, the GP
+ register) and stores the result as a 16 bit signed value in the
+ immediate operand field of the given instruction. For example:
+
+ `ld.w sdaoff(_a_variable)[gp],r6'
+
+ loads the contents of the location pointed to by the label
+ '_a_variable' into register 6, provided that the label is located
+ somewhere within +/- 32K of the address held in the GP register.
+ [Note the linker assumes that the GP register contains a fixed
+ address set to the address of the label called '__gp'. This can
+ either be set up automatically by the linker, or specifically set
+ by using the `--defsym __gp=<value>' command line option].
+
+`tdaoff()'
+ Computes the offset of the named variable from the start of the
+ Tiny Data Area (whoes address is held in register 30, the EP
+ register) and stores the result as a 4,5, 7 or 8 bit unsigned
+ value in the immediate operand field of the given instruction.
+ For example:
+
+ `sld.w tdaoff(_a_variable)[ep],r6'
+
+ loads the contents of the location pointed to by the label
+ '_a_variable' into register 6, provided that the label is located
+ somewhere within +256 bytes of the address held in the EP
+ register. [Note the linker assumes that the EP register contains
+ a fixed address set to the address of the label called '__ep'.
+ This can either be set up automatically by the linker, or
+ specifically set by using the `--defsym __ep=<value>' command line
+ option].
+
+`zdaoff()'
+ Computes the offset of the named variable from address 0 and
+ stores the result as a 16 bit signed value in the immediate
+ operand field of the given instruction. For example:
+
+ `movea zdaoff(_a_variable),zero,r6'
+
+ puts the address of the label '_a_variable' into register 6,
+ assuming that the label is somewhere within the first 32K of
+ memory. (Strictly speaking it also possible to access the last
+ 32K of memory as well, as the offsets are signed).
+
+`ctoff()'
+ Computes the offset of the named variable from the start of the
+ Call Table Area (whoes address is helg in system register 20, the
+ CTBP register) and stores the result a 6 or 16 bit unsigned value
+ in the immediate field of then given instruction or piece of data.
+ For example:
+
+ `callt ctoff(table_func1)'
+
+ will put the call the function whoes address is held in the call
+ table at the location labeled 'table_func1'.
+
+`.longcall `name''
+ Indicates that the following sequence of instructions is a long
+ call to function `name'. The linker will attempt to shorten this
+ call sequence if `name' is within a 22bit offset of the call. Only
+ valid if the `-mrelax' command line switch has been enabled.
+
+`.longjump `name''
+ Indicates that the following sequence of instructions is a long

+--------------------
+
+The Freescale XGATE version of `as' has a few machine dependent options.
+
+`-mshort'
+ This option controls the ABI and indicates to use a 16-bit integer
+ ABI. It has no effect on the assembled instructions. This is the
+ default.
+
+`-mlong'
+ This option controls the ABI and indicates to use a 32-bit integer
+ ABI.
+
+`-mshort-double'
+ This option controls the ABI and indicates to use a 32-bit float
+ ABI. This is the default.
+
+`-mlong-double'
+ This option controls the ABI and indicates to use a 64-bit float
+ ABI.
+
+`--print-insn-syntax'
+ You can use the `--print-insn-syntax' option to obtain the syntax
+ description of the instruction when an error is detected.
+
+`--print-opcodes'
+ The `--print-opcodes' option prints the list of all the
+ instructions with their syntax. Once the list is printed `as'

+
+9.51.2 Syntax
+-------------
+
+In XGATE RISC syntax, the instruction name comes first and it may be
+followed by up to three operands. Operands are separated by commas
+(`,'). `as' will complain if too many operands are specified for a
+given instruction. The same will happen if you specified too few
+operands.
+
+ nop
+ ldl #23
+ CMP R1, R2
+
+ The presence of a `;' character or a `!' character anywhere on a
+line indicates the start of a comment that extends to the end of that
+line.
+
+ A `*' or a `#' character at the start of a line also introduces a
+line comment, but these characters do not work elsewhere on the line.
+If the first character of the line is a `#' then as well as starting a
+comment, the line could also be logical line number directive (*note
+Comments::) or a preprocessor control command (*note Preprocessing::).
+
+ The XGATE assembler does not currently support a line separator
+character.
+
+ The following addressing modes are understood for XGATE:
+"Inherent"
+ `'
+
+"Immediate 3 Bit Wide"
+ `#NUMBER'
+
+"Immediate 4 Bit Wide"
+ `#NUMBER'
+
+"Immediate 8 Bit Wide"
+ `#NUMBER'
+
+"Monadic Addressing"
+ `REG'
+
+"Dyadic Addressing"
+ `REG, REG'
+
+"Triadic Addressing"
+ `REG, REG, REG'
+
+"Relative Addressing 9 Bit Wide"
+ `*SYMBOL'
+
+"Relative Addressing 10 Bit Wide"
+ `*SYMBOL'
+
+"Index Register plus Immediate Offset"
+ `REG, (REG, #NUMBER)'
+
+"Index Register plus Register Offset"
+ `REG, REG, REG'
+
+"Index Register plus Register Offset with Post-increment"
+ `REG, REG, REG+'
+
+"Index Register plus Register Offset with Pre-decrement"
+ `REG, REG, -REG'
+
+ The register can be either `R0', `R1', `R2', `R3', `R4', `R5',
+ `R6' or `R7'.
+
+
+ Convience macro opcodes to deal with 16-bit values have been added.
+
+"Immediate 16 Bit Wide"
+ `#NUMBER', or `*SYMBOL'
+
+ For example:
+
+ ldw R1, #1024
+ ldw R3, timer
+ ldw R1, (R1, #0)
+ COM R1

+ value in register 7.

+
+9.53.1 Command Line Options
+---------------------------
+
+`--text-section-literals | --no-text-section-literals'
+ Control the treatment of literal pools. The default is
+ `--no-text-section-literals', which places literals in separate
+ sections in the output file. This allows the literal pool to be
+ placed in a data RAM/ROM. With `--text-section-literals', the
+ literals are interspersed in the text section in order to keep
+ them as close as possible to their references. This may be
+ necessary for large assembly files, where the literals would
+ otherwise be out of range of the `L32R' instructions in the text
+ section. These options only affect literals referenced via
+ PC-relative `L32R' instructions; literals for absolute mode `L32R'
+ instructions are handled separately. *Note literal: Literal
+ Directive.
+
+`--absolute-literals | --no-absolute-literals'
+ Indicate to the assembler whether `L32R' instructions use absolute
+ or PC-relative addressing. If the processor includes the absolute
+ addressing option, the default is to use absolute `L32R'
+ relocations. Otherwise, only the PC-relative `L32R' relocations
+ can be used.
+
+`--target-align | --no-target-align'
+ Enable or disable automatic alignment to reduce branch penalties
+ at some expense in code size. *Note Automatic Instruction
+ Alignment: Xtensa Automatic Alignment. This optimization is
+ enabled by default. Note that the assembler will always align
+ instructions like `LOOP' that have fixed alignment requirements.
+
+`--longcalls | --no-longcalls'
+ Enable or disable transformation of call instructions to allow
+ calls across a greater range of addresses. *Note Function Call
+ Relaxation: Xtensa Call Relaxation. This option should be used
+ when call targets can potentially be out of range. It may degrade
+ both code size and performance, but the linker can generally
+ optimize away the unnecessary overhead when a call ends up within
+ range. The default is `--no-longcalls'.
+
+`--transform | --no-transform'
+ Enable or disable all assembler transformations of Xtensa
+ instructions, including both relaxation and optimization. The
+ default is `--transform'; `--no-transform' should only be used in
+ the rare cases when the instructions must be exactly as specified
+ in the assembly source. Using `--no-transform' causes out of range
+ instruction operands to be errors.
+
+`--rename-section OLDNAME=NEWNAME'
+ Rename the OLDNAME section to NEWNAME. This option can be used
+ multiple times to rename multiple sections.
+
+`--trampolines | --no-trampolines'
+ Enable or disable transformation of jump instructions to allow
+ jumps across a greater range of addresses. *Note Jump
+ Trampolines: Xtensa Jump Relaxation. This option should be used
+ when jump targets can potentially be out of range. In the absence
+ of such jumps this option does not affect code size or
+ performance. The default is `--trampolines'.

+
+9.53.2 Assembler Syntax
+-----------------------
+
+Block comments are delimited by `/*' and `*/'. End of line comments
+may be introduced with either `#' or `//'.
+
+ If a `#' appears as the first character of a line then the whole
+line is treated as a comment, but in this case the line could also be a
+logical line number directive (*note Comments::) or a preprocessor
+control command (*note Preprocessing::).
+
+ Instructions consist of a leading opcode or macro name followed by
+whitespace and an optional comma-separated list of operands:
+
+ OPCODE [OPERAND, ...]
+
+ Instructions must be separated by a newline or semicolon (`;').
+
+ FLIX instructions, which bundle multiple opcodes together in a single
+instruction, are specified by enclosing the bundled opcodes inside
+braces:
+
+ {
+ [FORMAT]
+ OPCODE0 [OPERANDS]
+ OPCODE1 [OPERANDS]
+ OPCODE2 [OPERANDS]
+ ...
+ }
+
+ The opcodes in a FLIX instruction are listed in the same order as the
+corresponding instruction slots in the TIE format declaration.
+Directives and labels are not allowed inside the braces of a FLIX
+instruction. A particular TIE format name can optionally be specified
+immediately after the opening brace, but this is usually unnecessary.
+The assembler will automatically search for a format that can encode the
+specified opcodes, so the format name need only be specified in rare
+cases where there is more than one applicable format and where it
+matters which of those formats is used. A FLIX instruction can also be
+specified on a single line by separating the opcodes with semicolons:
+
+ { [FORMAT;] OPCODE0 [OPERANDS]; OPCODE1 [OPERANDS]; OPCODE2 [OPERANDS]; ... }
+
+ If an opcode can only be encoded in a FLIX instruction but is not
+specified as part of a FLIX bundle, the assembler will choose the
+smallest format where the opcode can be encoded and will fill unused
+instruction slots with no-ops.

+
+9.53.2.1 Opcode Names
+.....................
+
+See the `Xtensa Instruction Set Architecture (ISA) Reference Manual'
+for a complete list of opcodes and descriptions of their semantics.
+
+ If an opcode name is prefixed with an underscore character (`_'),
+`as' will not transform that instruction in any way. The underscore
+prefix disables both optimization (*note Xtensa Optimizations: Xtensa
+Optimizations.) and relaxation (*note Xtensa Relaxation: Xtensa
+Relaxation.) for that particular instruction. Only use the underscore
+prefix when it is essential to select the exact opcode produced by the
+assembler. Using this feature unnecessarily makes the code less
+efficient by disabling assembler optimization and less flexible by
+disabling relaxation.
+
+ Note that this special handling of underscore prefixes only applies
+to Xtensa opcodes, not to either built-in macros or user-defined macros.
+When an underscore prefix is used with a macro (e.g., `_MOV'), it
+refers to a different macro. The assembler generally provides built-in
+macros both with and without the underscore prefix, where the underscore
+versions behave as if the underscore carries through to the instructions
+in the macros. For example, `_MOV' may expand to `_MOV.N'.
+
+ The underscore prefix only applies to individual instructions, not to
+series of instructions. For example, if a series of instructions have
+underscore prefixes, the assembler will not transform the individual
+instructions, but it may insert other instructions between them (e.g.,
+to align a `LOOP' instruction). To prevent the assembler from
+modifying a series of instructions as a whole, use the `no-transform'
+directive. *Note transform: Transform Directive.

+9.53.2.2 Register Names
+.......................
+
+The assembly syntax for a register file entry is the "short" name for a
+TIE register file followed by the index into that register file. For
+example, the general-purpose `AR' register file has a short name of
+`a', so these registers are named `a0'...`a15'. As a special feature,
+`sp' is also supported as a synonym for `a1'. Additional registers may
+be added by processor configuration options and by designer-defined TIE
+extensions. An initial `$' character is optional in all register names.

+
+9.53.3 Xtensa Optimizations
+---------------------------
+
+The optimizations currently supported by `as' are generation of density
+instructions where appropriate and automatic branch target alignment.

+* Menu:
+
+* Density Instructions:: Using Density Instructions.
+* Xtensa Automatic Alignment:: Automatic Instruction Alignment.
+
+
+File: as.info, Node: Density Instructions, Next: Xtensa Automatic Alignment, Up: Xtensa Optimizations
+
+9.53.3.1 Using Density Instructions
+...................................
+
+The Xtensa instruction set has a code density option that provides
+16-bit versions of some of the most commonly used opcodes. Use of these
+opcodes can significantly reduce code size. When possible, the
+assembler automatically translates instructions from the core Xtensa
+instruction set into equivalent instructions from the Xtensa code
+density option. This translation can be disabled by using underscore
+prefixes (*note Opcode Names: Xtensa Opcodes.), by using the
+`--no-transform' command-line option (*note Command Line Options:
+Xtensa Options.), or by using the `no-transform' directive (*note
+transform: Transform Directive.).
+
+ It is a good idea _not_ to use the density instructions directly.
+The assembler will automatically select dense instructions where
+possible. If you later need to use an Xtensa processor without the code
+density option, the same assembly code will then work without
+modification.
+
+
+File: as.info, Node: Xtensa Automatic Alignment, Prev: Density Instructions, Up: Xtensa Optimizations
+
+9.53.3.2 Automatic Instruction Alignment
+........................................
+
+The Xtensa assembler will automatically align certain instructions, both
+to optimize performance and to satisfy architectural requirements.
+
+ As an optimization to improve performance, the assembler attempts to
+align branch targets so they do not cross instruction fetch boundaries.
+(Xtensa processors can be configured with either 32-bit or 64-bit
+instruction fetch widths.) An instruction immediately following a call
+is treated as a branch target in this context, because it will be the
+target of a return from the call. This alignment has the potential to
+reduce branch penalties at some expense in code size. This
+optimization is enabled by default. You can disable it with the
+`--no-target-align' command-line option (*note Command Line Options:
+Xtensa Options.).
+
+ The target alignment optimization is done without adding instructions
+that could increase the execution time of the program. If there are
+density instructions in the code preceding a target, the assembler can
+change the target alignment by widening some of those instructions to
+the equivalent 24-bit instructions. Extra bytes of padding can be
+inserted immediately following unconditional jump and return
+instructions. This approach is usually successful in aligning many,
+but not all, branch targets.
+
+ The `LOOP' family of instructions must be aligned such that the
+first instruction in the loop body does not cross an instruction fetch
+boundary (e.g., with a 32-bit fetch width, a `LOOP' instruction must be
+on either a 1 or 2 mod 4 byte boundary). The assembler knows about
+this restriction and inserts the minimal number of 2 or 3 byte no-op
+instructions to satisfy it. When no-op instructions are added, any
+label immediately preceding the original loop will be moved in order to
+refer to the loop instruction, not the newly generated no-op
+instruction. To preserve binary compatibility across processors with
+different fetch widths, the assembler conservatively assumes a 32-bit
+fetch width when aligning `LOOP' instructions (except if the first
+instruction in the loop is a 64-bit instruction).
+
+ Previous versions of the assembler automatically aligned `ENTRY'
+instructions to 4-byte boundaries, but that alignment is now the
+programmer's responsibility.
+
+

+
+9.53.4 Xtensa Relaxation
+------------------------
+
+When an instruction operand is outside the range allowed for that
+particular instruction field, `as' can transform the code to use a
+functionally-equivalent instruction or sequence of instructions. This
+process is known as "relaxation". This is typically done for branch
+instructions because the distance of the branch targets is not known
+until assembly-time. The Xtensa assembler offers branch relaxation and
+also extends this concept to function calls, `MOVI' instructions and
+other instructions with immediate fields.
+
+* Menu:
+
+* Xtensa Branch Relaxation:: Relaxation of Branches.

+* Xtensa Jump Relaxation:: Relaxation of Jumps.
+* Xtensa Immediate Relaxation:: Relaxation of other Immediate Fields.
+
+
+File: as.info, Node: Xtensa Branch Relaxation, Next: Xtensa Call Relaxation, Up: Xtensa Relaxation
+
+9.53.4.1 Conditional Branch Relaxation
+......................................
+
+When the target of a branch is too far away from the branch itself,
+i.e., when the offset from the branch to the target is too large to fit
+in the immediate field of the branch instruction, it may be necessary to
+replace the branch with a branch around a jump. For example,
+
+ beqz a2, L
+
+ may result in:
+
+ bnez.n a2, M
+ j L
+ M:
+
+ (The `BNEZ.N' instruction would be used in this example only if the
+density option is available. Otherwise, `BNEZ' would be used.)
+
+ This relaxation works well because the unconditional jump instruction
+has a much larger offset range than the various conditional branches.
+However, an error will occur if a branch target is beyond the range of a
+jump instruction. `as' cannot relax unconditional jumps. Similarly,
+an error will occur if the original input contains an unconditional
+jump to a target that is out of range.
+
+ Branch relaxation is enabled by default. It can be disabled by using
+underscore prefixes (*note Opcode Names: Xtensa Opcodes.), the
+`--no-transform' command-line option (*note Command Line Options:
+Xtensa Options.), or the `no-transform' directive (*note transform:
+Transform Directive.).
+
+
+File: as.info, Node: Xtensa Call Relaxation, Next: Xtensa Jump Relaxation, Prev: Xtensa Branch Relaxation, Up: Xtensa Relaxation
+
+9.53.4.2 Function Call Relaxation
+.................................
+
+Function calls may require relaxation because the Xtensa immediate call
+instructions (`CALL0', `CALL4', `CALL8' and `CALL12') provide a
+PC-relative offset of only 512 Kbytes in either direction. For larger
+programs, it may be necessary to use indirect calls (`CALLX0',
+`CALLX4', `CALLX8' and `CALLX12') where the target address is specified
+in a register. The Xtensa assembler can automatically relax immediate
+call instructions into indirect call instructions. This relaxation is
+done by loading the address of the called function into the callee's
+return address register and then using a `CALLX' instruction. So, for
+example:
+
+ call8 func
+
+ might be relaxed to:
+
+ .literal .L1, func
+ l32r a8, .L1
+ callx8 a8
+
+ Because the addresses of targets of function calls are not generally
+known until link-time, the assembler must assume the worst and relax all
+the calls to functions in other source files, not just those that really
+will be out of range. The linker can recognize calls that were
+unnecessarily relaxed, and it will remove the overhead introduced by the
+assembler for those cases where direct calls are sufficient.
+
+ Call relaxation is disabled by default because it can have a negative
+effect on both code size and performance, although the linker can
+usually eliminate the unnecessary overhead. If a program is too large
+and some of the calls are out of range, function call relaxation can be
+enabled using the `--longcalls' command-line option or the `longcalls'
+directive (*note longcalls: Longcalls Directive.).
+
+
+File: as.info, Node: Xtensa Jump Relaxation, Next: Xtensa Immediate Relaxation, Prev: Xtensa Call Relaxation, Up: Xtensa Relaxation
+
+9.53.4.3 Jump Relaxation
+........................
+
+Jump instruction may require relaxation because the Xtensa jump
+instruction (`J') provide a PC-relative offset of only 128 Kbytes in
+either direction. One option is to use jump long (`J.L') instruction,
+which depending on jump distance may be assembled as jump (`J') or
+indirect jump (`JX'). However it needs a free register. When there's
+no spare register it is possible to plant intermediate jump sites
+(trampolines) between the jump instruction and its target. These sites
+may be located in areas unreachable by normal code execution flow, in
+that case they only contain intermediate jumps, or they may be inserted
+in the middle of code block, in which case there's an additional jump
+from the beginning of the trampoline to the instruction past its end.
+So, for example:
+
+ j 1f
+ ...
+ retw
+ ...
+ mov a10, a2
+ call8 func
+ ...
+ 1:
+ ...
+
+ might be relaxed to:
+
+ j .L0_TR_1
+ ...
+ retw
+ .L0_TR_1:
+ j 1f
+ ...
+ mov a10, a2
+ call8 func
+ ...
+ 1:
+ ...
+
+ or to:
+
+ j .L0_TR_1
+ ...
+ retw
+ ...
+ mov a10, a2
+ j .L0_TR_0
+ .L0_TR_1:
+ j 1f
+ .L0_TR_0:
+ call8 func
+ ...
+ 1:
+ ...
+
+ The Xtensa assempler uses trampolines with jump around only when it
+cannot find suitable unreachable trampoline. There may be multiple
+trampolines between the jump instruction and its target.
+
+ This relaxation does not apply to jumps to undefined symbols,
+assuming they will reach their targets once resolved.
+
+ Jump relaxation is enabled by default because it does not affect
+code size or performance while the code itself is small. This
+relaxation may be disabled completely with `--no-trampolines' or
+`--no-transform' command-line options (*note Command Line Options:
+Xtensa Options.).

+Xtensa Opcodes.), the `--no-transform' command-line option (*note
+Command Line Options: Xtensa Options.), or the `no-transform' directive
+(*note transform: Transform Directive.).
+
+ The `MOVI' machine instruction can only materialize values in the
+range from -2048 to 2047. Values outside this range are best
+materialized with `L32R' instructions. Thus:
+
+ movi a0, 100000
+
+ is assembled into the following machine code:
+
+ .literal .L1, 100000
+ l32r a0, .L1
+
+ The `L8UI' machine instruction can only be used with immediate
+offsets in the range from 0 to 255. The `L16SI' and `L16UI' machine
+instructions can only be used with offsets from 0 to 510. The `L32I'
+machine instruction can only be used with offsets from 0 to 1020. A
+load offset outside these ranges can be materialized with an `L32R'
+instruction if the destination register of the load is different than
+the source address register. For example:
+
+ l32i a1, a0, 2040
+
+ is translated to:
+
+ .literal .L1, 2040
+ l32r a1, .L1
+ add a1, a0, a1
+ l32i a1, a1, 0
+
+If the load destination and source address register are the same, an
+out-of-range offset causes an error.
+
+ The Xtensa `ADDI' instruction only allows immediate operands in the
+range from -128 to 127. There are a number of alternate instruction
+sequences for the `ADDI' operation. First, if the immediate is 0, the
+`ADDI' will be turned into a `MOV.N' instruction (or the equivalent
+`OR' instruction if the code density option is not available). If the
+`ADDI' immediate is outside of the range -128 to 127, but inside the
+range -32896 to 32639, an `ADDMI' instruction or `ADDMI'/`ADDI'
+sequence will be used. Finally, if the immediate is outside of this
+range and a free register is available, an `L32R'/`ADD' sequence will
+be used with a literal allocated from the literal pool.
+
+ For example:
+
+ addi a5, a6, 0
+ addi a5, a6, 512
+ addi a5, a6, 513
+ addi a5, a6, 50000
+
+ is assembled into the following:
+
+ .literal .L1, 50000
+ mov.n a5, a6
+ addmi a5, a6, 0x200
+ addmi a5, a6, 0x200
+ addi a5, a5, 1
+ l32r a5, .L1
+ add a5, a6, a5

+
+9.53.5 Directives
+-----------------
+
+The Xtensa assembler supports a region-based directive syntax:
+
+ .begin DIRECTIVE [OPTIONS]
+ ...
+ .end DIRECTIVE
+
+ All the Xtensa-specific directives that apply to a region of code use
+this syntax.
+
+ The directive applies to code between the `.begin' and the `.end'.
+The state of the option after the `.end' reverts to what it was before
+the `.begin'. A nested `.begin'/`.end' region can further change the
+state of the directive without having to be aware of its outer state.
+For example, consider:
+
+ .begin no-transform
+ L: add a0, a1, a2
+ .begin transform
+ M: add a0, a1, a2
+ .end transform
+ N: add a0, a1, a2
+ .end no-transform
+
+ The `ADD' opcodes at `L' and `N' in the outer `no-transform' region
+both result in `ADD' machine instructions, but the assembler selects an
+`ADD.N' instruction for the `ADD' at `M' in the inner `transform'
+region.
+
+ The advantage of this style is that it works well inside macros
+which can preserve the context of their callers.
+
+ The following directives are available:
+
+* Menu:
+
+* Schedule Directive:: Enable instruction scheduling.
+* Longcalls Directive:: Use Indirect Calls for Greater Range.
+* Transform Directive:: Disable All Assembler Transformations.
+* Literal Directive:: Intermix Literals with Instructions.
+* Literal Position Directive:: Specify Inline Literal Pool Locations.
+* Literal Prefix Directive:: Specify Literal Section Name Prefix.
+* Absolute Literals Directive:: Control PC-Relative vs. Absolute Literals.
+
+
+File: as.info, Node: Schedule Directive, Next: Longcalls Directive, Up: Xtensa Directives
+
+9.53.5.1 schedule
+.................
+
+The `schedule' directive is recognized only for compatibility with
+Tensilica's assembler.
+
+ .begin [no-]schedule
+ .end [no-]schedule
+
+ This directive is ignored and has no effect on `as'.
+
+
+File: as.info, Node: Longcalls Directive, Next: Transform Directive, Prev: Schedule Directive, Up: Xtensa Directives
+
+9.53.5.2 longcalls
+..................
+
+The `longcalls' directive enables or disables function call relaxation.
+*Note Function Call Relaxation: Xtensa Call Relaxation.
+
+ .begin [no-]longcalls
+ .end [no-]longcalls
+
+ Call relaxation is disabled by default unless the `--longcalls'
+command-line option is specified. The `longcalls' directive overrides
+the default determined by the command-line options.
+
+
+File: as.info, Node: Transform Directive, Next: Literal Directive, Prev: Longcalls Directive, Up: Xtensa Directives
+
+9.53.5.3 transform
+..................
+
+This directive enables or disables all assembler transformation,
+including relaxation (*note Xtensa Relaxation: Xtensa Relaxation.) and
+optimization (*note Xtensa Optimizations: Xtensa Optimizations.).
+
+ .begin [no-]transform
+ .end [no-]transform
+
+ Transformations are enabled by default unless the `--no-transform'
+option is used. The `transform' directive overrides the default
+determined by the command-line options. An underscore opcode prefix,
+disabling transformation of that opcode, always takes precedence over
+both directives and command-line flags.
+
+
+File: as.info, Node: Literal Directive, Next: Literal Position Directive, Prev: Transform Directive, Up: Xtensa Directives
+
+9.53.5.4 literal
+................
+
+The `.literal' directive is used to define literal pool data, i.e.,
+read-only 32-bit data accessed via `L32R' instructions.
+
+ .literal LABEL, VALUE[, VALUE...]
+
+ This directive is similar to the standard `.word' directive, except
+that the actual location of the literal data is determined by the
+assembler and linker, not by the position of the `.literal' directive.
+Using this directive gives the assembler freedom to locate the literal
+data in the most appropriate place and possibly to combine identical
+literals. For example, the code:
+
+ entry sp, 40
+ .literal .L1, sym
+ l32r a4, .L1
+
+ can be used to load a pointer to the symbol `sym' into register
+`a4'. The value of `sym' will not be placed between the `ENTRY' and
+`L32R' instructions; instead, the assembler puts the data in a literal
+pool.
+
+ Literal pools are placed by default in separate literal sections;
+however, when using the `--text-section-literals' option (*note Command
+Line Options: Xtensa Options.), the literal pools for PC-relative mode
+`L32R' instructions are placed in the current section.(1) These text
+section literal pools are created automatically before `ENTRY'
+instructions and manually after `.literal_position' directives (*note
+literal_position: Literal Position Directive.). If there are no
+preceding `ENTRY' instructions, explicit `.literal_position' directives
+must be used to place the text section literal pools; otherwise, `as'
+will report an error.
+
+ When literals are placed in separate sections, the literal section
+names are derived from the names of the sections where the literals are
+defined. The base literal section names are `.literal' for PC-relative
+mode `L32R' instructions and `.lit4' for absolute mode `L32R'
+instructions (*note absolute-literals: Absolute Literals Directive.).
+These base names are used for literals defined in the default `.text'
+section. For literals defined in other sections or within the scope of
+a `literal_prefix' directive (*note literal_prefix: Literal Prefix
+Directive.), the following rules determine the literal section name:
+
+ 1. If the current section is a member of a section group, the literal
+ section name includes the group name as a suffix to the base
+ `.literal' or `.lit4' name, with a period to separate the base
+ name and group name. The literal section is also made a member of
+ the group.
+
+ 2. If the current section name (or `literal_prefix' value) begins with
+ "`.gnu.linkonce.KIND.'", the literal section name is formed by
+ replacing "`.KIND'" with the base `.literal' or `.lit4' name. For
+ example, for literals defined in a section named
+ `.gnu.linkonce.t.func', the literal section will be
+ `.gnu.linkonce.literal.func' or `.gnu.linkonce.lit4.func'.
+
+ 3. If the current section name (or `literal_prefix' value) ends with
+ `.text', the literal section name is formed by replacing that
+ suffix with the base `.literal' or `.lit4' name. For example, for
+ literals defined in a section named `.iram0.text', the literal
+ section will be `.iram0.literal' or `.iram0.lit4'.
+
+ 4. If none of the preceding conditions apply, the literal section
+ name is formed by adding the base `.literal' or `.lit4' name as a
+ suffix to the current section name (or `literal_prefix' value).
+
+ ---------- Footnotes ----------
+
+ (1) Literals for the `.init' and `.fini' sections are always placed
+in separate sections, even when `--text-section-literals' is enabled.
+
+
+File: as.info, Node: Literal Position Directive, Next: Literal Prefix Directive, Prev: Literal Directive, Up: Xtensa Directives
+
+9.53.5.5 literal_position
+.........................
+
+When using `--text-section-literals' to place literals inline in the
+section being assembled, the `.literal_position' directive can be used
+to mark a potential location for a literal pool.
+
+ .literal_position
+
+ The `.literal_position' directive is ignored when the
+`--text-section-literals' option is not used or when `L32R'
+instructions use the absolute addressing mode.
+
+ The assembler will automatically place text section literal pools
+before `ENTRY' instructions, so the `.literal_position' directive is
+only needed to specify some other location for a literal pool. You may
+need to add an explicit jump instruction to skip over an inline literal
+pool.
+
+ For example, an interrupt vector does not begin with an `ENTRY'
+instruction so the assembler will be unable to automatically find a good
+place to put a literal pool. Moreover, the code for the interrupt
+vector must be at a specific starting address, so the literal pool
+cannot come before the start of the code. The literal pool for the
+vector must be explicitly positioned in the middle of the vector (before
+any uses of the literals, due to the negative offsets used by
+PC-relative `L32R' instructions). The `.literal_position' directive
+can be used to do this. In the following code, the literal for `M'
+will automatically be aligned correctly and is placed after the
+unconditional jump.
+
+ .global M
+ code_start:
+ j continue
+ .literal_position
+ .align 4
+ continue:
+ movi a4, M
+
+
+File: as.info, Node: Literal Prefix Directive, Next: Absolute Literals Directive, Prev: Literal Position Directive, Up: Xtensa Directives
+
+9.53.5.6 literal_prefix
+.......................
+
+The `literal_prefix' directive allows you to override the default
+literal section names, which are derived from the names of the sections
+where the literals are defined.
+
+ .begin literal_prefix [NAME]
+ .end literal_prefix
+
+ For literals defined within the delimited region, the literal section
+names are derived from the NAME argument instead of the name of the
+current section. The rules used to derive the literal section names do
+not change. *Note literal: Literal Directive. If the NAME argument is
+omitted, the literal sections revert to the defaults. This directive
+has no effect when using the `--text-section-literals' option (*note
+Command Line Options: Xtensa Options.).
+
+
+File: as.info, Node: Absolute Literals Directive, Prev: Literal Prefix Directive, Up: Xtensa Directives
+
+9.53.5.7 absolute-literals
+..........................
+
+The `absolute-literals' and `no-absolute-literals' directives control
+the absolute vs. PC-relative mode for `L32R' instructions. These are
+relevant only for Xtensa configurations that include the absolute
+addressing option for `L32R' instructions.
+
+ .begin [no-]absolute-literals
+ .end [no-]absolute-literals
+
+ These directives do not change the `L32R' mode--they only cause the
+assembler to emit the appropriate kind of relocation for `L32R'
+instructions and to place the literal values in the appropriate section.
+To change the `L32R' mode, the program must write the `LITBASE' special
+register. It is the programmer's responsibility to keep track of the
+mode and indicate to the assembler which mode is used in each region of
+code.
+
+ If the Xtensa configuration includes the absolute `L32R' addressing
+option, the default is to assume absolute `L32R' addressing unless the
+`--no-absolute-literals' command-line option is specified. Otherwise,
+the default is to assume PC-relative `L32R' addressing. The
+`absolute-literals' directive can then be used to override the default
+determined by the command-line options.

+10 Reporting Bugs
+*****************
+
+Your bug reports play an essential role in making `as' reliable.
+
+ Reporting a bug may help you by bringing a solution to your problem,
+or it may not. But in any case the principal function of a bug report
+is to help the entire community by making the next version of `as' work
+better. Bug reports are your contribution to the maintenance of `as'.
+
+ In order for a bug report to serve its purpose, you must include the
+information that enables us to fix the bug.
+
+* Menu:
+
+* Bug Criteria:: Have you found a bug?
+* Bug Reporting:: How to report bugs
+
+
+File: as.info, Node: Bug Criteria, Next: Bug Reporting, Up: Reporting Bugs
+
+10.1 Have You Found a Bug?
+==========================
+
+If you are not sure whether you have found a bug, here are some
+guidelines:
+
+ * If the assembler gets a fatal signal, for any input whatever, that
+ is a `as' bug. Reliable assemblers never crash.
+
+ * If `as' produces an error message for valid input, that is a bug.
+
+ * If `as' does not produce an error message for invalid input, that
+ is a bug. However, you should note that your idea of "invalid
+ input" might be our idea of "an extension" or "support for
+ traditional practice".
+
+ * If you are an experienced user of assemblers, your suggestions for
+ improvement of `as' are welcome in any case.
+
+
+File: as.info, Node: Bug Reporting, Prev: Bug Criteria, Up: Reporting Bugs
+
+10.2 How to Report Bugs
+=======================
+
+A number of companies and individuals offer support for GNU products.
+If you obtained `as' from a support organization, we recommend you
+contact that organization first.
+
+ You can find contact information for many support companies and
+individuals in the file `etc/SERVICE' in the GNU Emacs distribution.
+
+ In any event, we also recommend that you send bug reports for `as'
+to `http://www.sourceware.org/bugzilla/'.
+
+ The fundamental principle of reporting bugs usefully is this:
+*report all the facts*. If you are not sure whether to state a fact or
+leave it out, state it!
+
+ Often people omit facts because they think they know what causes the
+problem and assume that some details do not matter. Thus, you might
+assume that the name of a symbol you use in an example does not matter.
+Well, probably it does not, but one cannot be sure. Perhaps the bug
+is a stray memory reference which happens to fetch from the location
+where that name is stored in memory; perhaps, if the name were
+different, the contents of that location would fool the assembler into
+doing the right thing despite the bug. Play it safe and give a
+specific, complete example. That is the easiest thing for you to do,
+and the most helpful.
+
+ Keep in mind that the purpose of a bug report is to enable us to fix
+the bug if it is new to us. Therefore, always write your bug reports
+on the assumption that the bug has not been reported previously.
+
+ Sometimes people give a few sketchy facts and ask, "Does this ring a
+bell?" This cannot help us fix a bug, so it is basically useless. We
+respond by asking for enough details to enable us to investigate. You
+might as well expedite matters by sending them to begin with.
+
+ To enable us to fix the bug, you should include all these things:
+
+ * The version of `as'. `as' announces it if you start it with the
+ `--version' argument.
+
+ Without this, we will not know whether there is any point in
+ looking for the bug in the current version of `as'.
+
+ * Any patches you may have applied to the `as' source.
+
+ * The type of machine you are using, and the operating system name
+ and version number.
+
+ * What compiler (and its version) was used to compile `as'--e.g.
+ "`gcc-2.7'".
+
+ * The command arguments you gave the assembler to assemble your
+ example and observe the bug. To guarantee you will not omit
+ something important, list them all. A copy of the Makefile (or
+ the output from make) is sufficient.
+
+ If we were to try to guess the arguments, we would probably guess
+ wrong and then we might not encounter the bug.
+
+ * A complete input file that will reproduce the bug. If the bug is
+ observed when the assembler is invoked via a compiler, send the
+ assembler source, not the high level language source. Most
+ compilers will produce the assembler source when run with the `-S'
+ option. If you are using `gcc', use the options `-v
+ --save-temps'; this will save the assembler source in a file with
+ an extension of `.s', and also show you exactly how `as' is being
+ run.
+
+ * A description of what behavior you observe that you believe is
+ incorrect. For example, "It gets a fatal signal."
+
+ Of course, if the bug is that `as' gets a fatal signal, then we
+ will certainly notice it. But if the bug is incorrect output, we
+ might not notice unless it is glaringly wrong. You might as well
+ not give us a chance to make a mistake.
+
+ Even if the problem you experience is a fatal signal, you should
+ still say so explicitly. Suppose something strange is going on,
+ such as, your copy of `as' is out of sync, or you have encountered
+ a bug in the C library on your system. (This has happened!) Your
+ copy might crash and ours would not. If you told us to expect a
+ crash, then when ours fails to crash, we would know that the bug
+ was not happening for us. If you had not told us to expect a
+ crash, then we would not be able to draw any conclusion from our
+ observations.
+
+ * If you wish to suggest changes to the `as' source, send us context
+ diffs, as generated by `diff' with the `-u', `-c', or `-p' option.
+ Always send diffs from the old file to the new file. If you even
+ discuss something in the `as' source, refer to it by context, not
+ by line number.
+
+ The line numbers in our development sources will not match those
+ in your sources. Your line numbers would convey no useful
+ information to us.
+
+ Here are some things that are not necessary:
+
+ * A description of the envelope of the bug.
+
+ Often people who encounter a bug spend a lot of time investigating
+ which changes to the input file will make the bug go away and which
+ changes will not affect it.
+
+ This is often time consuming and not very useful, because the way
+ we will find the bug is by running a single example under the
+ debugger with breakpoints, not by pure deduction from a series of
+ examples. We recommend that you save your time for something else.
+
+ Of course, if you can find a simpler example to report _instead_
+ of the original one, that is a convenience for us. Errors in the
+ output will be easier to spot, running under the debugger will take
+ less time, and so on.
+
+ However, simplification is not vital; if you do not want to do
+ this, report the bug anyway and send us the entire test case you
+ used.
+
+ * A patch for the bug.
+
+ A patch for the bug does help us if it is a good one. But do not
+ omit the necessary information, such as the test case, on the
+ assumption that a patch is all we need. We might see problems
+ with your patch and decide to fix the problem another way, or we
+ might not understand it at all.
+
+ Sometimes with a program as complicated as `as' it is very hard to
+ construct an example that will make the program follow a certain
+ path through the code. If you do not send us the example, we will
+ not be able to construct one, so we will not be able to verify
+ that the bug is fixed.
+
+ And if we cannot understand what bug you are trying to fix, or why
+ your patch should be an improvement, we will not install it. A
+ test case will help us to understand.
+
+ * A guess about what the bug is or what it depends on.
+
+ Such guesses are usually wrong. Even we cannot guess right about
+ such things without first using the debugger to find the facts.

+ This License applies to any manual or other work, in any medium,
+ that contains a notice placed by the copyright holder saying it
+ can be distributed under the terms of this License. Such a notice
+ grants a world-wide, royalty-free license, unlimited in duration,
+ to use that work under the conditions stated herein. The
+ "Document", below, refers to any such manual or work. Any member
+ of the public is a licensee, and is addressed as "you". You
+ accept the license if you copy, modify or distribute the work in a
+ way requiring permission under copyright law.
+
+ A "Modified Version" of the Document means any work containing the
+ Document or a portion of it, either copied verbatim, or with
+ modifications and/or translated into another language.
+
+ A "Secondary Section" is a named appendix or a front-matter section
+ of the Document that deals exclusively with the relationship of the
+ publishers or authors of the Document to the Document's overall
+ subject (or to related matters) and contains nothing that could
+ fall directly within that overall subject. (Thus, if the Document
+ is in part a textbook of mathematics, a Secondary Section may not
+ explain any mathematics.) The relationship could be a matter of
+ historical connection with the subject or with related matters, or
+ of legal, commercial, philosophical, ethical or political position
+ regarding them.
+
+ The "Invariant Sections" are certain Secondary Sections whose
+ titles are designated, as being those of Invariant Sections, in
+ the notice that says that the Document is released under this
+ License. If a section does not fit the above definition of
+ Secondary then it is not allowed to be designated as Invariant.
+ The Document may contain zero Invariant Sections. If the Document
+ does not identify any Invariant Sections then there are none.
+
+ The "Cover Texts" are certain short passages of text that are
+ listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+ that says that the Document is released under this License. A
+ Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+ be at most 25 words.
+
+ A "Transparent" copy of the Document means a machine-readable copy,
+ represented in a format whose specification is available to the
+ general public, that is suitable for revising the document
+ straightforwardly with generic text editors or (for images
+ composed of pixels) generic paint programs or (for drawings) some
+ widely available drawing editor, and that is suitable for input to
+ text formatters or for automatic translation to a variety of
+ formats suitable for input to text formatters. A copy made in an
+ otherwise Transparent file format whose markup, or absence of
+ markup, has been arranged to thwart or discourage subsequent
+ modification by readers is not Transparent. An image format is
+ not Transparent if used for any substantial amount of text. A
+ copy that is not "Transparent" is called "Opaque".
+
+ Examples of suitable formats for Transparent copies include plain
+ ASCII without markup, Texinfo input format, LaTeX input format,
+ SGML or XML using a publicly available DTD, and
+ standard-conforming simple HTML, PostScript or PDF designed for
+ human modification. Examples of transparent image formats include
+ PNG, XCF and JPG. Opaque formats include proprietary formats that
+ can be read and edited only by proprietary word processors, SGML or
+ XML for which the DTD and/or processing tools are not generally
+ available, and the machine-generated HTML, PostScript or PDF
+ produced by some word processors for output purposes only.
+
+ The "Title Page" means, for a printed book, the title page itself,
+ plus such following pages as are needed to hold, legibly, the
+ material this License requires to appear in the title page. For
+ works in formats which do not have any title page as such, "Title
+ Page" means the text near the most prominent appearance of the
+ work's title, preceding the beginning of the body of the text.
+
+ The "publisher" means any person or entity that distributes copies
+ of the Document to the public.
+
+ A section "Entitled XYZ" means a named subunit of the Document
+ whose title either is precisely XYZ or contains XYZ in parentheses
+ following text that translates XYZ in another language. (Here XYZ
+ stands for a specific section name mentioned below, such as
+ "Acknowledgements", "Dedications", "Endorsements", or "History".)
+ To "Preserve the Title" of such a section when you modify the
+ Document means that it remains a section "Entitled XYZ" according
+ to this definition.
+
+ The Document may include Warranty Disclaimers next to the notice
+ which states that this License applies to the Document. These
+ Warranty Disclaimers are considered to be included by reference in
+ this License, but only as regards disclaiming warranties: any other
+ implication that these Warranty Disclaimers may have is void and
+ has no effect on the meaning of this License.
+
+ 2. VERBATIM COPYING
+
+ You may copy and distribute the Document in any medium, either
+ commercially or noncommercially, provided that this License, the
+ copyright notices, and the license notice saying this License
+ applies to the Document are reproduced in all copies, and that you
+ add no other conditions whatsoever to those of this License. You
+ may not use technical measures to obstruct or control the reading
+ or further copying of the copies you make or distribute. However,
+ you may accept compensation in exchange for copies. If you
+ distribute a large enough number of copies you must also follow
+ the conditions in section 3.
+
+ You may also lend copies, under the same conditions stated above,
+ and you may publicly display copies.
+
+ 3. COPYING IN QUANTITY
+
+ If you publish printed copies (or copies in media that commonly
+ have printed covers) of the Document, numbering more than 100, and
+ the Document's license notice requires Cover Texts, you must
+ enclose the copies in covers that carry, clearly and legibly, all
+ these Cover Texts: Front-Cover Texts on the front cover, and
+ Back-Cover Texts on the back cover. Both covers must also clearly
+ and legibly identify you as the publisher of these copies. The
+ front cover must present the full title with all words of the
+ title equally prominent and visible. You may add other material
+ on the covers in addition. Copying with changes limited to the
+ covers, as long as they preserve the title of the Document and
+ satisfy these conditions, can be treated as verbatim copying in
+ other respects.
+
+ If the required texts for either cover are too voluminous to fit
+ legibly, you should put the first ones listed (as many as fit
+ reasonably) on the actual cover, and continue the rest onto
+ adjacent pages.
+
+ If you publish or distribute Opaque copies of the Document
+ numbering more than 100, you must either include a
+ machine-readable Transparent copy along with each Opaque copy, or
+ state in or with each Opaque copy a computer-network location from
+ which the general network-using public has access to download
+ using public-standard network protocols a complete Transparent
+ copy of the Document, free of added material. If you use the
+ latter option, you must take reasonably prudent steps, when you
+ begin distribution of Opaque copies in quantity, to ensure that
+ this Transparent copy will remain thus accessible at the stated
+ location until at least one year after the last time you
+ distribute an Opaque copy (directly or through your agents or
+ retailers) of that edition to the public.
+
+ It is requested, but not required, that you contact the authors of
+ the Document well before redistributing any large number of
+ copies, to give them a chance to provide you with an updated
+ version of the Document.
+
+ 4. MODIFICATIONS
+
+ You may copy and distribute a Modified Version of the Document
+ under the conditions of sections 2 and 3 above, provided that you
+ release the Modified Version under precisely this License, with
+ the Modified Version filling the role of the Document, thus
+ licensing distribution and modification of the Modified Version to
+ whoever possesses a copy of it. In addition, you must do these
+ things in the Modified Version:
+
+ A. Use in the Title Page (and on the covers, if any) a title
+ distinct from that of the Document, and from those of
+ previous versions (which should, if there were any, be listed
+ in the History section of the Document). You may use the
+ same title as a previous version if the original publisher of
+ that version gives permission.
+
+ B. List on the Title Page, as authors, one or more persons or
+ entities responsible for authorship of the modifications in
+ the Modified Version, together with at least five of the
+ principal authors of the Document (all of its principal
+ authors, if it has fewer than five), unless they release you
+ from this requirement.
+
+ C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+ D. Preserve all the copyright notices of the Document.
+
+ E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+ F. Include, immediately after the copyright notices, a license
+ notice giving the public permission to use the Modified
+ Version under the terms of this License, in the form shown in
+ the Addendum below.
+
+ G. Preserve in that license notice the full lists of Invariant
+ Sections and required Cover Texts given in the Document's
+ license notice.
+
+ H. Include an unaltered copy of this License.
+
+ I. Preserve the section Entitled "History", Preserve its Title,
+ and add to it an item stating at least the title, year, new
+ authors, and publisher of the Modified Version as given on
+ the Title Page. If there is no section Entitled "History" in
+ the Document, create one stating the title, year, authors,
+ and publisher of the Document as given on its Title Page,
+ then add an item describing the Modified Version as stated in
+ the previous sentence.
+
+ J. Preserve the network location, if any, given in the Document
+ for public access to a Transparent copy of the Document, and
+ likewise the network locations given in the Document for
+ previous versions it was based on. These may be placed in
+ the "History" section. You may omit a network location for a
+ work that was published at least four years before the
+ Document itself, or if the original publisher of the version
+ it refers to gives permission.
+
+ K. For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the
+ section all the substance and tone of each of the contributor
+ acknowledgements and/or dedications given therein.
+
+ L. Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section
+ titles.
+
+ M. Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+ N. Do not retitle any existing section to be Entitled
+ "Endorsements" or to conflict in title with any Invariant
+ Section.
+
+ O. Preserve any Warranty Disclaimers.
+
+ If the Modified Version includes new front-matter sections or
+ appendices that qualify as Secondary Sections and contain no
+ material copied from the Document, you may at your option
+ designate some or all of these sections as invariant. To do this,
+ add their titles to the list of Invariant Sections in the Modified
+ Version's license notice. These titles must be distinct from any
+ other section titles.
+
+ You may add a section Entitled "Endorsements", provided it contains
+ nothing but endorsements of your Modified Version by various
+ parties--for example, statements of peer review or that the text
+ has been approved by an organization as the authoritative
+ definition of a standard.
+
+ You may add a passage of up to five words as a Front-Cover Text,
+ and a passage of up to 25 words as a Back-Cover Text, to the end
+ of the list of Cover Texts in the Modified Version. Only one
+ passage of Front-Cover Text and one of Back-Cover Text may be
+ added by (or through arrangements made by) any one entity. If the
+ Document already includes a cover text for the same cover,
+ previously added by you or by arrangement made by the same entity
+ you are acting on behalf of, you may not add another; but you may
+ replace the old one, on explicit permission from the previous
+ publisher that added the old one.
+
+ The author(s) and publisher(s) of the Document do not by this
+ License give permission to use their names for publicity for or to
+ assert or imply endorsement of any Modified Version.
+
+ 5. COMBINING DOCUMENTS
+
+ You may combine the Document with other documents released under
+ this License, under the terms defined in section 4 above for
+ modified versions, provided that you include in the combination
+ all of the Invariant Sections of all of the original documents,
+ unmodified, and list them all as Invariant Sections of your
+ combined work in its license notice, and that you preserve all
+ their Warranty Disclaimers.
+
+ The combined work need only contain one copy of this License, and
+ multiple identical Invariant Sections may be replaced with a single
+ copy. If there are multiple Invariant Sections with the same name
+ but different contents, make the title of each such section unique
+ by adding at the end of it, in parentheses, the name of the
+ original author or publisher of that section if known, or else a
+ unique number. Make the same adjustment to the section titles in
+ the list of Invariant Sections in the license notice of the
+ combined work.
+
+ In the combination, you must combine any sections Entitled
+ "History" in the various original documents, forming one section
+ Entitled "History"; likewise combine any sections Entitled
+ "Acknowledgements", and any sections Entitled "Dedications". You
+ must delete all sections Entitled "Endorsements."
+
+ 6. COLLECTIONS OF DOCUMENTS
+
+ You may make a collection consisting of the Document and other
+ documents released under this License, and replace the individual
+ copies of this License in the various documents with a single copy
+ that is included in the collection, provided that you follow the
+ rules of this License for verbatim copying of each of the
+ documents in all other respects.
+
+ You may extract a single document from such a collection, and
+ distribute it individually under this License, provided you insert
+ a copy of this License into the extracted document, and follow
+ this License in all other respects regarding verbatim copying of
+ that document.
+
+ 7. AGGREGATION WITH INDEPENDENT WORKS
+
+ A compilation of the Document or its derivatives with other
+ separate and independent documents or works, in or on a volume of
+ a storage or distribution medium, is called an "aggregate" if the
+ copyright resulting from the compilation is not used to limit the
+ legal rights of the compilation's users beyond what the individual
+ works permit. When the Document is included in an aggregate, this
+ License does not apply to the other works in the aggregate which
+ are not themselves derivative works of the Document.
+
+ If the Cover Text requirement of section 3 is applicable to these
+ copies of the Document, then if the Document is less than one half
+ of the entire aggregate, the Document's Cover Texts may be placed
+ on covers that bracket the Document within the aggregate, or the
+ electronic equivalent of covers if the Document is in electronic
+ form. Otherwise they must appear on printed covers that bracket
+ the whole aggregate.
+
+ 8. TRANSLATION
+
+ Translation is considered a kind of modification, so you may
+ distribute translations of the Document under the terms of section
+ 4. Replacing Invariant Sections with translations requires special
+ permission from their copyright holders, but you may include
+ translations of some or all Invariant Sections in addition to the
+ original versions of these Invariant Sections. You may include a
+ translation of this License, and all the license notices in the
+ Document, and any Warranty Disclaimers, provided that you also
+ include the original English version of this License and the
+ original versions of those notices and disclaimers. In case of a
+ disagreement between the translation and the original version of
+ this License or a notice or disclaimer, the original version will
+ prevail.
+
+ If a section in the Document is Entitled "Acknowledgements",
+ "Dedications", or "History", the requirement (section 4) to
+ Preserve its Title (section 1) will typically require changing the
+ actual title.
+
+ 9. TERMINATION
+
+ You may not copy, modify, sublicense, or distribute the Document
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense, or distribute it is void,
+ and will automatically terminate your rights under this License.
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly
+ and finally terminates your license, and (b) permanently, if the
+ copyright holder fails to notify you of the violation by some
+ reasonable means prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from
+ that copyright holder, and you cure the violation prior to 30 days
+ after your receipt of the notice.
+
+ Termination of your rights under this section does not terminate
+ the licenses of parties who have received copies or rights from
+ you under this License. If your rights have been terminated and
+ not permanently reinstated, receipt of a copy of some or all of
+ the same material does not give you any rights to use it.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+ The Free Software Foundation may publish new, revised versions of
+ the GNU Free Documentation License from time to time. Such new
+ versions will be similar in spirit to the present version, but may
+ differ in detail to address new problems or concerns. See
+ `http://www.gnu.org/copyleft/'.
+
+ Each version of the License is given a distinguishing version
+ number. If the Document specifies that a particular numbered
+ version of this License "or any later version" applies to it, you
+ have the option of following the terms and conditions either of
+ that specified version or of any later version that has been
+ published (not as a draft) by the Free Software Foundation. If
+ the Document does not specify a version number of this License,
+ you may choose any version ever published (not as a draft) by the
+ Free Software Foundation. If the Document specifies that a proxy
+ can decide which future versions of this License can be used, that
+ proxy's public statement of acceptance of a version permanently
+ authorizes you to choose that version for the Document.
+
+ 11. RELICENSING
+
+ "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+ World Wide Web server that publishes copyrightable works and also
+ provides prominent facilities for anybody to edit those works. A
+ public wiki that anybody can edit is an example of such a server.
+ A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+ site means any set of copyrightable works thus published on the MMC
+ site.
+
+ "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+ license published by Creative Commons Corporation, a not-for-profit
+ corporation with a principal place of business in San Francisco,
+ California, as well as future copyleft versions of that license
+ published by that same organization.
+
+ "Incorporate" means to publish or republish a Document, in whole or
+ in part, as part of another Document.
+
+ An MMC is "eligible for relicensing" if it is licensed under this
+ License, and if all works that were first published under this
+ License somewhere other than this MMC, and subsequently
+ incorporated in whole or in part into the MMC, (1) had no cover
+ texts or invariant sections, and (2) were thus incorporated prior
+ to November 1, 2008.
+
+ The operator of an MMC Site may republish an MMC contained in the
+ site under CC-BY-SA on the same site at any time before August 1,
+ 2009, provided the MMC is eligible for relicensing.
+
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+ Copyright (C) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.3
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+
+ If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts." line with this:
+
+ with the Invariant Sections being LIST THEIR TITLES, with
+ the Front-Cover Texts being LIST, and with the Back-Cover Texts
+ being LIST.
+
+ If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+ If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License, to
+permit their use in free software.

+
+=======================================================================
+Original Instruction table specification document:
+
+ MIPS Coprocessor Table Specification
+ ====================================
+
+This document describes the format of the MIPS coprocessor table. The
+table specifies a list of valid functions, data registers and control
+registers that can be used in coprocessor instructions. This list,
+together with the coprocessor instruction classes listed below,
+specifies the complete list of coprocessor instructions that will
+be recognized and assembled by the GNU assembler. In effect,
+this makes the GNU assembler table-driven, where the table is
+specified by the programmer.
+
+The table is an ordinary text file that the GNU assembler reads when
+it starts. Using the information in the table, the assembler
+generates an internal list of valid coprocessor registers and
+functions. The assembler uses this internal list in addition to the
+standard MIPS registers and instructions which are built-in to the
+assembler during code generation.
+
+To specify the coprocessor table when invoking the GNU assembler, use
+the command line option "--itbl file", where file is the
+complete name of the table, including path and extension.
+
+Examples:
+
+ gas -t cop.tbl test.s -o test.o
+ gas -t /usr/local/lib/cop.tbl test.s -o test.o
+ gas --itbl d:\gnu\data\cop.tbl test.s -o test.o
+
+Only one table may be supplied during a single invocation of
+the assembler.
+
+
+Instruction classes
+===================
+
+Below is a list of the valid coprocessor instruction classes for
+any given coprocessor "z". These instructions are already recognized
+by the assembler, and are listed here only for reference.
+
+Class format instructions
+-------------------------------------------------
+Class1:
+ op base rt offset
+ LWCz rt,offset (base)
+ SWCz rt,offset (base)
+Class2:
+ COPz sub rt rd 0
+ MTCz rt,rd
+ MFCz rt,rd
+ CTCz rt,rd
+ CFCz rt,rd
+Class3:
+ COPz CO cofun
+ COPz cofun
+Class4:
+ COPz BC br offset
+ BCzT offset
+ BCzF offset
+Class5:
+ COPz sub rt rd 0
+ DMFCz rt,rd
+ DMTCz rt,rd
+Class6:
+ op base rt offset
+ LDCz rt,offset (base)
+ SDCz rt,offset (base)
+Class7:
+ COPz BC br offset
+ BCzTL offset
+ BCzFL offset
+
+The coprocessor table defines coprocessor-specific registers that can
+be used with all of the above classes of instructions, where
+appropriate. It also defines additional coprocessor-specific
+functions for Class3 (COPz cofun) instructions, Thus, the table allows
+the programmer to use convenient mnemonics and operands for these
+functions, instead of the COPz mmenmonic and cofun operand.
+
+The names of the MIPS general registers and their aliases are defined
+by the assembler and will be recognized as valid register names by the
+assembler when used (where allowed) in coprocessor instructions.
+However, the names and values of all coprocessor data and control
+register mnemonics must be specified in the coprocessor table.
+
+
+Table Grammar
+=============
+
+Here is the grammar for the coprocessor table:
+
+ table -> entry*
+
+ entry -> [z entrydef] [comment] '\n'
+
+ entrydef -> type name val
+ entrydef -> 'insn' name val funcdef ; type of entry (instruction)
+
+ z -> 'p'['0'..'3'] ; processor number
+ type -> ['dreg' | 'creg' | 'greg' ] ; type of entry (register)
+ ; 'dreg', 'creg' or 'greg' specifies a data, control, or general
+ ; register mnemonic, respectively
+ name -> [ltr|dec]* ; mnemonic of register/function
+ val -> [dec|hex] ; register/function number (integer constant)
+
+ funcdef -> frange flags fields
+ ; bitfield range for opcode
+ ; list of fields' formats
+ fields -> field*
+ field -> [','] ftype frange flags
+ flags -> ['*' flagexpr]
+ flagexpr -> '[' flagexpr ']'
+ flagexpr -> val '|' flagexpr
+ ftype -> [ type | 'immed' | 'addr' ]
+ ; 'immed' specifies an immediate value; see grammar for "val" above
+ ; 'addr' specifies a C identifier; name of symbol to be resolved at
+ ; link time
+ frange -> ':' val '-' val ; starting to ending bit positions, where
+ ; where 0 is least significant bit
+ frange -> (null) ; default range of 31-0 will be assumed
+
+ comment -> [';'|'#'] [char]*
+ char -> any printable character
+ ltr -> ['a'..'z'|'A'..'Z']
+ dec -> ['0'..'9']* ; value in decimal
+ hex -> '0x'['0'..'9' | 'a'..'f' | 'A'..'F']* ; value in hexadecimal
+
+
+Examples
+========
+
+Example 1:
+
+The table:
+
+ p1 dreg d1 1 ; data register "d1" for COP1 has value 1
+ p1 creg c3 3 ; ctrl register "c3" for COP1 has value 3
+ p3 func fill 0x1f:24-20 ; function "fill" for COP3 has value 31 and
+ ; no fields
+
+will allow the assembler to accept the following coprocessor instructions:
+
+ LWC1 d1,0x100 ($2)
+ fill
+
+Here, the general purpose register "$2", and instruction "LWC1", are standard
+mnemonics built-in to the MIPS assembler.
+
+
+Example 2:
+
+The table:
+
+ p3 dreg d3 3 ; data register "d3" for COP3 has value 3
+ p3 creg c2 22 ; control register "c2" for COP3 has value 22
+ p3 func fee 0x1f:24-20 dreg:17-13 creg:12-8 immed:7-0
+ ; function "fee" for COP3 has value 31, and 3 fields
+ ; consisting of a data register, a control register,
+ ; and an immediate value.
+
+will allow the assembler to accept the following coprocessor instruction:
+
+ fee d3,c2,0x1
+
+and will emit the object code:
+
+ 31-26 25 24-20 19-18 17-13 12-8 7-0
+ COPz CO fun dreg creg immed
+ 010011 1 11111 00 00011 10110 00000001
+
+ 0x4ff07601
+
+
+Example 3:
+
+The table:
+
+ p3 dreg d3 3 ; data register "d3" for COP3 has value 3
+ p3 creg c2 22 ; control register "c2" for COP3 has value 22
+ p3 func fuu 0x01f00001 dreg:17-13 creg:12-8
+
+will allow the assembler to accept the following coprocessor
+instruction:
+
+ fuu d3,c2
+
+and will emit the object code:
+
+ 31-26 25 24-20 19-18 17-13 12-8 7-0
+ COPz CO fun dreg creg
+ 010011 1 11111 00 00011 10110 00000001
+
+ 0x4ff07601
+
+In this way, the programmer can force arbitrary bits of an instruction
+to have predefined values.
+
+=======================================================================
+Additional notes:
+
+Encoding of ranges:
+To handle more than one bit position range within an instruction,
+use 0s to mask out the ranges which don't apply.
+May decide to modify the syntax to allow commas separate multiple
+ranges within an instruction (range','range).
+
+Changes in grammar:
+ The number of parms argument to the function entry
+was deleted from the original format such that we now count the fields.
+
+----
+FIXME! should really change lexical analyzer
+to recognize 'dreg' etc. in context sensitive way.
+Currently function names or mnemonics may be incorrectly parsed as keywords
+
+FIXME! hex is ambiguous with any digit

+
+ B*() is used to specify the base opcode bytes. Fields to be filled
+ in later, leave zero. Call this first.
+
+ F() and FE() are used to fill in fields within the base opcode bytes. You MUST
+ call B*() before any F() or FE().
+
+ [UN]*O*(), PC*() appends operands to the end of the opcode. You
+ must call P() and B*() before any of these, so that the fixups
+ have the right byte location.
+ O = signed, UO = unsigned, NO = negated, PC = pcrel
+
+ IMM() adds an immediate and fills in the field for it.
+ NIMM() same, but negates the immediate.
+ NBIMM() same, but negates the immediate, for sbb.
+ DSP() adds a displacement, and fills in the field for it.
+
+ Note that order is significant for the O, IMM, and DSP macros, as
+ they append their data to the operand buffer in the order that you
+ call them.
+
+ Use "disp" for displacements whenever possible; this handles the
+ "0" case properly. */

+ B*() is used to specify the base opcode bytes. Fields to be filled

+
+ F() and FE() are used to fill in fields within the base opcode bytes. You MUST
+ call B*() before any F() or FE().
+
+ [UN]*O*(), PC*() appends operands to the end of the opcode. You
+ must call P() and B*() before any of these, so that the fixups
+ have the right byte location.
+ O = signed, UO = unsigned, NO = negated, PC = pcrel
+
+ IMM() adds an immediate and fills in the field for it.
+ NIMM() same, but negates the immediate.
+ NBIMM() same, but negates the immediate, for sbb.
+ DSP() adds a displacement, and fills in the field for it.
+
+ Note that order is significant for the O, IMM, and DSP macros, as
+ they append their data to the operand buffer in the order that you
+ call them.
+
