+\S{cl-0.98.09b with John Coffman patches released 28-Oct-2001} Version 0.98.09b with John Coffman patches released 28-Oct-2001
+
+Changes from 0.98.07 release to 98.09b as of 28-Oct-2001
+
+\b More closely compatible with 0.98 when -O0 is implied
+or specified.  Not strictly identical, since backward 
+branches in range of short offsets are recognized, and signed
+byte values with no explicit size specification will be
+assembled as a single byte.
+
+\b More forgiving with the PUSH instruction.  0.98 requires
+a size to be specified always.  0.98.09b will imply the size
+from the current BITS setting (16 or 32).
+
+\b Changed definition of the optimization flag:
+
+        -O0     strict two-pass assembly, JMP and Jcc are
+                handled more like 0.98, except that back-
+                ward JMPs are short, if possible.
+
+        -O1     strict two-pass assembly, but forward
+                branches are assembled with code guaranteed
+                to reach; may produce larger code than
+                -O0, but will produce successful assembly
+                more often if branch offset sizes are not
+                specified.
+
+        -O2     multi-pass optimization, minimize branch
+                offsets; also will minimize signed immed-
+                iate bytes, overriding size specification.
+
+        -O3     like -O2, but more passes taken, if needed
+
+
+\S{cl-0.98.07 released 01/28/01} Version 0.98.07 released 01/28/01
+
+\b       Added Stepane Denis' SSE2 instructions to a *working*
+        version of the code - some earlier versions were based on
+        broken code - sorry 'bout that. version "0.98.07"
+

+        someone's old backup of "outform.h". version "0.98.06e" 
+
+01/09/01
+
+\b fbk - finally added the fix for the "multiple %includes bug",
+        known since 7/27/99 - reported originally (?) and sent to
+        us by Austin Lunnen - he reports that John Fine had a fix
+        within the day. Here it is...
+
+\b Nelson Rush resigns from the group. Big thanks to Nelson for

+\S{cl-0.98.03 with John Coffman's changes released 27-Jul-2000} Version 0.98.03 with John Coffman's changes released 27-Jul-2000
+
+\b Added signed byte optimizations for the 0x81/0x83 class
+of instructions: ADC, ADD, AND, CMP, OR, SBB, SUB, XOR:
+when used as 'ADD reg16,imm' or 'ADD reg32,imm.'  Also
+optimization of signed byte form of 'PUSH imm' and 'IMUL
+reg,imm'/'IMUL reg,reg,imm.'  No size specification is needed.
+
+\b Added multi-pass JMP and Jcc offset optimization.  Offsets
+on forward references will preferentially use the short form,
+without the need to code a specific size (short or near) for
+the branch.  Added instructions for 'Jcc label' to use the
+form 'Jnotcc $+3/JMP label', in cases where a short offset
+is out of bounds.  If compiling for a 386 or higher CPU, then
+the 386 form of Jcc will be used instead.
+
+This feature is controlled by a new command-line switch: "O",
+(upper case letter O).  "-O0" reverts the assembler to no
+extra optimization passes, "-O1" allows up to 5 extra passes,
+and "-O2"(default), allows up to 10 extra optimization passes.
+
+\b Added a new directive:  'cpu XXX', where XXX is any of: 
+8086, 186, 286, 386, 486, 586, pentium, 686, PPro, P2, P3 or
+Katmai.  All are case insensitive.  All instructions will
+be selected only if they apply to the selected cpu or lower.
+Corrected a couple of bugs in cpu-dependence in 'insns.dat'.
+
+\b Added to 'standard.mac', the "use16" and "use32" forms of
+the "bits 16/32" directive. This is nothing new, just conforms
+to a lot of other assemblers. (minor)
+
+\b Changed label allocation from 320/32 (10000 labels @ 200K+) 
+to 32/37 (1000 labels); makes running under DOS much easier.
+Since additional label space is allocated dynamically, this
+should have no effect on large programs with lots of labels.
+The 37 is a prime, believed to be better for hashing. (minor)
+
+
+\S{cl-0.98.03} Version 0.98.03
+
+"Integrated patchfile 0.98-0.98.01.  I call this version 0.98.03 for
+historical reasons: 0.98.02 was trashed." --John Coffman
+<johninsd@san.rr.com>, 27-Jul-2000
+
+\b Kendall Bennett's SciTech MGL changes
+
+\b Note that you must define "TASM_COMPAT" at compile-time
+to get the Tasm Ideal Mode compatibility.
+
+\b All changes can be compiled in and out using the TASM_COMPAT macros,
+and when compiled without TASM_COMPAT defined we get the exact same
+binary as the unmodified 0.98 sources.
+
+\b standard.mac, macros.c: Added macros to ignore TASM directives before
+first include
+
+\b nasm.h: Added extern declaration for tasm_compatible_mode
+
+\b nasm.c: Added global variable tasm_compatible_mode
+
+\b Added command line switch for TASM compatible mode (-t)
+
+\b Changed version command line to reflect when compiled with TASM additions
+
+\b Added response file processing to allow all arguments on a single
+line (response file is @resp rather than -@resp for NASM format).
+
+\b labels.c: Changes islocal() macro to support TASM style @@local labels.
+
+\b Added islocalchar() macro to support TASM style @@local labels.
+
+\b parser.c: Added support for TASM style memory references (ie: mov
+[DWORD eax],10 rather than the NASM style mov DWORD [eax],10).
+
+\b preproc.c: Added new directives, %arg, %local, %stacksize to directives
+table
+
+\b Added support for TASM style directives without a leading % symbol.
+
+\b Integrated a block of changes from Andrew Zabolotny <bit@eltech.ru>:
+
+\b A new keyword %xdefine and its case-insensitive counterpart %ixdefine.
+They work almost the same way as %define and %idefine but expand
+the definition immediately, not on the invocation. Something like a cross
+between %define and %assign. The "x" suffix stands for "eXpand", so
+"xdefine" can be deciphered as "expand-and-define". Thus you can do
+things like this:
+
+\c      %assign ofs     0
+\c
+\c      %macro  arg     1
+\c              %xdefine %1 dword [esp+ofs]
+\c              %assign ofs ofs+4
+\c      %endmacro
+
+\b Changed the place where the expansion of %$name macros are expanded.
+Now they are converted into ..@ctxnum.name form when detokenizing, so
+there are no quirks as before when using %$name arguments to macros,
+in macros etc. For example:
+
+\c      %macro  abc     1
+\c              %define %1 hello
+\c      %endm
+\c
+\c      abc     %$here
+\c      %$here
+
+    Now last line will be expanded into "hello" as expected. This also allows
+    for lots of goodies, a good example are extended "proc" macros included
+    in this archive.
+
+\b Added a check for "cstk" in smacro_defined() before calling get_ctx() -
+    this allows for things like:
+
+\c      %ifdef %$abc
+\c      %endif
+
+    to work without warnings even in no context.
+
+\b Added a check for "cstk" in %if*ctx and %elif*ctx directives -
+    this allows to use %ifctx without excessive warnings. If there is
+    no active context, %ifctx goes through "false" branch.
+
+\b Removed "user error: " prefix with %error directive: it just clobbers the
+    output and has absolutely no functionality. Besides, this allows to write
+    macros that does not differ from built-in functions in any way.
+
+\b Added expansion of string that is output by %error directive. Now you
+    can do things like:
+
+\c      %define hello(x) Hello, x!
+\c
+\c      %define %$name andy
+\c      %error "hello(%$name)"
+
+    Same happened with %include directive.
+
+\b Now all directives that expect an identifier will try to expand and
+    concatenate everything without whitespaces in between before usage.
+    For example, with "unfixed" nasm the commands
+
+\c      %define %$abc hello
+\c      %define __%$abc goodbye
+\c      __%$abc
+
+    would produce "incorrect" output: last line will expand to
+
+\c      hello goodbyehello
+
+    Not quite what you expected, eh? :-) The answer is that preprocessor
+    treats the %define construct as if it would be
+
+\c      %define __ %$abc goodbye
+
+    (note the white space between __ and %$abc). After my "fix" it
+    will "correctly" expand into
+
+\c      goodbye
+
+    as expected. Note that I use quotes around words "correct", "incorrect"
+    etc because this is rather a feature not a bug; however current behaviour
+    is more logical (and allows more advanced macro usage :-).
+
+    Same change was applied to:
+        %push,%macro,%imacro,%define,%idefine,%xdefine,%ixdefine,
+        %assign,%iassign,%undef
+
+\b A new directive [WARNING {+|-}warning-id] have been added. It works only
+    if the assembly phase is enabled (i.e. it doesn't work with nasm -e).
+
+\b A new warning type: macro-selfref. By default this warning is disabled;
+    when enabled NASM warns when a macro self-references itself; for example
+    the following source:
+
+\c        [WARNING macro-selfref]
+\c
+\c        %macro          push    1-*
+\c                %rep    %0
+\c                        push    %1
+\c                        %rotate 1
+\c                %endrep
+\c        %endmacro
+\c
+\c                        push    eax,ebx,ecx
+
+    will produce a warning, but if we remove the first line we won't see it
+    anymore (which is The Right Thing To Do {tm} IMHO since C preprocessor
+    eats such constructs without warnings at all).
+
+\b Added a "error" routine to preprocessor which always will set ERR_PASS1
+    bit in severity_code. This removes annoying repeated errors on first
+    and second passes from preprocessor.
+
+\b Added the %+ operator in single-line macros for concatenating two
+    identifiers. Usage example:
+
+\c        %define _myfunc _otherfunc
+\c        %define cextern(x) _ %+ x
+\c        cextern (myfunc)
+
+    After first expansion, third line will become "_myfunc". After this
+    expansion is performed again so it becomes "_otherunc".
+
+\b Now if preprocessor is in a non-emitting state, no warning or error
+    will be emitted. Example:
+
+\c        %if 1
+\c                mov     eax,ebx
+\c        %else
+\c                put anything you want between these two brackets,
+\c                even macro-parameter references %1 or local
+\c                labels %$zz or macro-local labels %%zz - no
+\c                warning will be emitted.
+\c        %endif
+
+\b Context-local variables on expansion as a last resort are looked up
+    in outer contexts. For example, the following piece:
+
+\c        %push   outer
+\c        %define %$a [esp]
+\c
+\c                %push   inner
+\c                %$a
+\c                %pop
+\c        %pop
+
+    will expand correctly the fourth line to [esp]; if we'll define another
+    %$a inside the "inner" context, it will take precedence over outer
+    definition. However, this modification has been applied only to
+    expand_smacro and not to smacro_define: as a consequence expansion
+    looks in outer contexts, but %ifdef won't look in outer contexts.
+
+    This behaviour is needed because we don't want nested contexts to
+    act on already defined local macros. Example:
+
+\c        %define %$arg1  [esp+4]
+\c        test    eax,eax
+\c        if      nz
+\c                mov     eax,%$arg1
+\c        endif
+
+    In this example the "if" mmacro enters into the "if" context, so %$arg1
+    is not valid anymore inside "if". Of course it could be worked around
+    by using explicitely %$$arg1 but this is ugly IMHO.
+
+\b Fixed memory leak in %undef. The origline wasn't freed before
+    exiting on success.
+
+\b Fixed trap in preprocessor when line expanded to empty set of tokens.
+    This happens, for example, in the following case:
+
+\c        #define SOMETHING
+\c        SOMETHING
+
+
+\S{cl-0.98} Version 0.98
+
+All changes since NASM 0.98p3 have been produced by H. Peter Anvin <hpa@zytor.com>.
+
+\b The documentation comment delimiter is \# not #.
+
+\b Allow EQU definitions to refer to external labels; reported by
+  Pedro Gimeno.
+
+\b Re-enable support for RDOFF v1; reported by Pedro Gimeno.
+
+\b Updated License file per OK from Simon and Julian.
+
+
+\S{cl-0.98p9} Version 0.98p9
+
+\b Update documentation (although the instruction set reference will
+  have to wait; I don't want to hold up the 0.98 release for it.)
+
+\b Verified that the NASM implementation of the PEXTRW and PMOVMSKB
+  instructions is correct.  The encoding differs from what the Intel
+  manuals document, but the Pentium III behaviour matches NASM, not
+  the Intel manuals.
+
+\b Fix handling of implicit sizes in PSHUFW and PINSRW, reported by
+  Stefan Hoffmeister.
+
+\b Resurrect the -s option, which was removed when changing the
+  diagnostic output to stdout.
+
+
+\S{cl-0.98p8} Version 0.98p8
+
+\b Fix for "DB" when NASM is running on a bigendian machine.
+
+\b Invoke insns.pl once for each output script, making Makefile.in
+  legal for "make -j".
+
+\b Improve the Unix configure-based makefiles to make package
+  creation easier.
+
+\b Included an RPM .spec file for building RPM (RedHat Package Manager)
+  packages on Linux or Unix systems.
+
+\b Fix Makefile dependency problems.
+
+\b Change src/rdsrc.pl to include sectioning information in info
+  output; required for install-info to work.
+
+\b Updated the RDOFF distribution to version 2 from Jules; minor
+  massaging to make it compile in my environment.
+
+\b Split doc files that can be built by anyone with a Perl interpreter off
+  into a separate archive.
+
+\b "Dress rehearsal" release!
+
+
+\S{cl-0.98p7} Version 0.98p7
+
+\b Fixed opcodes with a third byte-sized immediate argument to not
+  complain if given "byte" on the immediate.
+
+\b Allow %undef to remove single-line macros with arguments.  This
+  matches the behaviour of #undef in the C preprocessor.
+
+\b Allow -d, -u, -i and -p to be specified as -D, -U, -I and -P for
+  compatibility with most C compilers and preprocessors.  This allows
+  Makefile options to be shared between cc and nasm, for example.
+
+\b Minor cleanups.
+
+\b Went through the list of Katmai instructions and hopefully fixed the
+  (rather few) mistakes in it.
+
+\b (Hopefully) fixed a number of disassembler bugs related to ambiguous
+  instructions (disambiguated by -p) and SSE instructions with REP.
+
+\b Fix for bug reported by Mark Junger: "call dword 0x12345678" should
+  work and may add an OSP (affected CALL, JMP, Jcc).
+
+\b Fix for environments when "stderr" isn't a compile-time constant.
+
+
+\S{cl-0.98p6} Version 0.98p6
+
+
+\b Took officially over coordination of the 0.98 release; so drop
+  the p3.x notation. Skipped p4 and p5 to avoid confusion with John
+  Fine's J4 and J5 releases.
+
+\b Update the documentation; however, it still doesn't include
+  documentation for the various new instructions.  I somehow wonder if
+  it makes sense to have an instruction set reference in the assembler
+  manual when Intel et al have PDF versions of their manuals online.
+
+\b Recognize "idt" or "centaur" for the -p option to ndisasm.
+
+\b Changed error messages back to stderr where they belong, but add an
+  -E option to redirect them elsewhere (the DOS shell cannot redirect
+  stderr.)
+
+\b -M option to generate Makefile dependencies (based on code from Alex
+  Verstak.)
+
+\b %undef preprocessor directive, and -u option, that undefines a
+  single-line macro.
+
+\b OS/2 Makefile (Mkfiles/Makefile.os2) for Borland under OS/2; from
+  Chuck Crayne.
+
+\b Various minor bugfixes (reported by):
+  - Dangling %s in preproc.c (Martin Junker)
+
+\b THERE ARE KNOWN BUGS IN SSE AND THE OTHER KATMAI INSTRUCTIONS.  I am
+  on a trip and didn't bring the Katmai instruction reference, so I
+  can't work on them right now.
+
+\b Updated the License file per agreement with Simon and Jules to
+  include a GPL distribution clause.
+
+
+\S{cl-0.98p3.7} Version 0.98p3.7
+
+\b (Hopefully) fixed the canned Makefiles to include the outrdf2 and
+  zoutieee modules.
+
+\b Renamed changes.asm to changed.asm.
+
+
+\S{cl-0.98p3.6} Version 0.98p3.6
+
+\b Fixed a bunch of instructions that were added in 0.98p3.5 which had
+  memory operands, and the address-size prefix was missing from the
+  instruction pattern.
+
+
+\S{cl-0.98p3.5} Version 0.98p3.5
+
+\b Merged in changes from John S. Fine's 0.98-J5 release.  John's based
+  0.98-J5 on my 0.98p3.3 release; this merges the changes.
+
+\b Expanded the instructions flag field to a long so we can fit more
+  flags; mark SSE (KNI) and AMD or Katmai-specific instructions as
+  such.
+
+\b Fix the "PRIV" flag on a bunch of instructions, and create new
+  "PROT" flag for protected-mode-only instructions (orthogonal to if
+  the instruction is privileged!) and new "SMM" flag for SMM-only
+  instructions.
+
+\b Added AMD-only SYSCALL and SYSRET instructions.
+
+\b Make SSE actually work, and add new Katmai MMX instructions.
+
+\b Added a -p (preferred vendor) option to ndisasm so that it can
+  distinguish e.g. Cyrix opcodes also used in SSE.  For example:
+
+\c      ndisasm -p cyrix aliased.bin
+\c      00000000  670F514310        paddsiw mm0,[ebx+0x10]
+\c      00000005  670F514320        paddsiw mm0,[ebx+0x20]
+\c      ndisasm -p intel aliased.bin
+\c      00000000  670F514310        sqrtps xmm0,[ebx+0x10]
+\c      00000005  670F514320        sqrtps xmm0,[ebx+0x20]
+
+\b Added a bunch of Cyrix-specific instructions.
+
+
+\S{cl-0.98p3.4} Version 0.98p3.4
+
+\b Made at least an attempt to modify all the additional Makefiles (in
+  the Mkfiles directory).  I can't test it, but this was the best I
+  could do.
+
+\b DOS DJGPP+"Opus Make" Makefile from John S. Fine.
+
+\b changes.asm changes from John S. Fine.
+
+
+\S{cl-0.98p3.3} Version 0.98p3.3
+
+\b Patch from Conan Brink to allow nesting of %rep directives.
+
+\b If we're going to allow INT01 as an alias for INT1/ICEBP (one of
+  Jules 0.98p3 changes), then we should allow INT03 as an alias for INT3
+  as well.
+
+\b Updated changes.asm to include the latest changes.
+
+\b Tried to clean up the <CR>s that had snuck in from a DOS/Windows
+  environment into my Unix environment, and try to make sure than
+  DOS/Windows users get them back.
+
+\b We would silently generate broken tools if insns.dat wasn't sorted
+  properly.  Change insns.pl so that the order doesn't matter.
+
+\b Fix bug in insns.pl (introduced by me) which would cause conditional
+  instructions to have an extra "cc" in disassembly, e.g. "jnz"
+  disassembled as "jccnz".
+
+
+\S{cl-0.98p3.2} Version 0.98p3.2
+
+\b Merged in John S. Fine's changes from his 0.98-J4 prerelease; see
+  http://www.csoft.net/cz/johnfine/
+
+\b Changed previous "spotless" Makefile target (appropriate for distribution)
+  to "distclean", and added "cleaner" target which is same as "clean"
+  except deletes files generated by Perl scripts; "spotless" is union.
+
+\b Removed BASIC programs from distribution.  Get a Perl interpreter
+  instead (see below.)
+
+\b Calling this "pre-release 3.2" rather than "p3-hpa2" because of
+  John's contributions.
+
+\b Actually link in the IEEE output format (zoutieee.c); fix a bunch of
+  compiler warnings in that file.  Note I don't know what IEEE output
+  is supposed to look like, so these changes were made "blind".
+
+
+\S{cl-0.98p3-hpa} Version 0.98p3-hpa
+
+\b Merged nasm098p3.zip with nasm-0.97.tar.gz to create a fully
+  buildable version for Unix systems (Makefile.in updates, etc.)
+
+\b Changed insns.pl to create the instruction tables in nasm.h and
+  names.c, so that a new instruction can be added by adding it *only*
+  to insns.dat.
+
+\b Added the following new instructions: SYSENTER, SYSEXIT, FXSAVE,
+  FXRSTOR, UD1, UD2 (the latter two are two opcodes that Intel
+  guarantee will never be used; one of them is documented as UD2 in
+  Intel documentation, the other one just as "Undefined Opcode" --
+  calling it UD1 seemed to make sense.)
+
+\b MAX_SYMBOL was defined to be 9, but LOADALL286 and LOADALL386 are 10
+  characters long.  Now MAX_SYMBOL is derived from insns.dat.
+
+\b A note on the BASIC programs included: forget them.  insns.bas is
+  already out of date.  Get yourself a Perl interpreter for your
+  platform of choice at
+  \W{http://www.cpan.org/ports/index.html}{http://www.cpan.org/ports/index.html}.
+
+
+\S{cl-0.98p3} Version 0.98 pre-release 3
+
+\b added response file support, improved command line handling, new layout
+help screen
+
+\b fixed limit checking bug, 'OUT byte nn, reg' bug, and a couple of rdoff
+related bugs, updated Wishlist; 0.98 Prerelease 3.
+
+
+\S{cl-0.98p2} Version 0.98 pre-release 2
+
+\b fixed bug in outcoff.c to do with truncating section names longer
+than 8 characters, referencing beyond end of string; 0.98 pre-release 2
+
+
+\S{cl-0.98p1} Version 0.98 pre-release 1
+
+\b Fixed a bug whereby STRUC didn't work at all in RDF.
+
+\b Fixed a problem with group specification in PUBDEFs in OBJ.
+
+\b Improved ease of adding new output formats. Contribution due to
+Fox Cutter.
+
+\b Fixed a bug in relocations in the `bin' format: was showing up when
+a relocatable reference crossed an 8192-byte boundary in any output
+section.
+
+\b Fixed a bug in local labels: local-label lookups were inconsistent
+between passes one and two if an EQU occurred between the definition
+of a global label and the subsequent use of a local label local to
+that global.
+
+\b Fixed a seg-fault in the preprocessor (again) which happened when
+you use a blank line as the first line of a multi-line macro
+definition and then defined a label on the same line as a call to
+that macro.
+
+\b Fixed a stale-pointer bug in the handling of the NASM environment
+variable. Thanks to Thomas McWilliams.
+
+\b ELF had a hard limit on the number of sections which caused
+segfaults when transgressed. Fixed.
+
+\b Added ability for ndisasm to read from stdin by using `-' as the
+filename.
+
+\b ndisasm wasn't outputting the TO keyword. Fixed.
+
+\b Fixed error cascade on bogus expression in %if - an error in
+evaluation was causing the entire %if to be discarded, thus creating
+trouble later when the %else or %endif was encountered.
+
+\b Forward reference tracking was instruction-granular not operand-
+granular, which was causing 286-specific code to be generated
+needlessly on code of the form `shr word [forwardref],1'. Thanks to
+Jim Hague for sending a patch.
+
+\b All messages now appear on stdout, as sending them to stderr serves
+no useful purpose other than to make redirection difficult.
+
+\b Fixed the problem with EQUs pointing to an external symbol - this
+now generates an error message.
+
+\b Allowed multiple size prefixes to an operand, of which only the first
+is taken into account.
+
+\b Incorporated John Fine's changes, including fixes of a large number
+of preprocessor bugs, some small problems in OBJ, and a reworking of
+label handling to define labels before their line is assembled, rather
+than after.
+
+\b Reformatted a lot of the source code to be more readable. Included
+'coding.txt' as a guideline for how to format code for contributors.
+
+\b Stopped nested %reps causing a panic - they now cause a slightly more
+friendly error message instead.
+
+\b Fixed floating point constant problems (patch by Pedro Gimeno)
+
+\b Fixed the return value of insn_size() not being checked for -1, indicating
+an error.
+
+\b Incorporated 3Dnow! instructions.
+
+\b Fixed the 'mov eax, eax + ebx' bug.
+
+\b Fixed the GLOBAL EQU bug in ELF. Released developers release 3.
+
+\b Incorporated John Fine's command line parsing changes
+
+\b Incorporated David Lindauer's OMF debug support
+
+\b Made changes for LCC 4.0 support (\c{__NASM_CDecl__}, removed register size
+specification warning when sizes agree).
+
+
+\H{cl-0.9x} NASM 0.9 Series
+
+Revisions before 0.98.
+
+
+\S{cl-0.97} Version 0.97 released December 1997
+
+\b This was entirely a bug-fix release to 0.96, which seems to have got
+cursed. Silly me.
+
+\b Fixed stupid mistake in OBJ which caused `MOV EAX,<constant>' to
+fail. Caused by an error in the `MOV EAX,<segment>' support.
+
+\b ndisasm hung at EOF when compiled with lcc on Linux because lcc on
+Linux somehow breaks feof(). ndisasm now does not rely on feof().
+
+\b A heading in the documentation was missing due to a markup error in
+the indexing. Fixed.
+
+\b Fixed failure to update all pointers on realloc() within extended-
+operand code in parser.c. Was causing wrong behaviour and seg faults
+on lines such as `dd 0.0,0.0,0.0,0.0,...'
+
+\b Fixed a subtle preprocessor bug whereby invoking one multi-line
+macro on the first line of the expansion of another, when the second
+had been invoked with a label defined before it, didn't expand the
+inner macro. 
+
+\b Added internal.doc back in to the distribution archives - it was
+missing in 0.96 *blush*
+
+\b Fixed bug causing 0.96 to be unable to assemble its own test files,
+specifically objtest.asm. *blush again*
+
+\b Fixed seg-faults and bogus error messages caused by mismatching
+%rep and %endrep within multi-line macro definitions.
+
+\b Fixed a problem with buffer overrun in OBJ, which was causing
+corruption at ends of long PUBDEF records.
+
+\b Separated DOS archives into main-program and documentation to reduce
+download size.
+
+
+\S{cl-0.96} Version 0.96 released November 1997
+
+\b Fixed a bug whereby, if `nasm sourcefile' would cause a filename
+collision warning and put output into `nasm.out', then `nasm
+sourcefile -o outputfile' still gave the warning even though the
+`-o' was honoured.
+Fixed name pollution under Digital UNIX: one of its header files
+defined R_SP, which broke the enum in nasm.h.
+
+\b Fixed minor instruction table problems: FUCOM and FUCOMP didn't have
+two-operand forms; NDISASM didn't recognise the longer register
+forms of PUSH and POP (eg FF F3 for PUSH BX); TEST mem,imm32 was
+flagged as undocumented; the 32-bit forms of CMOV had 16-bit operand
+size prefixes; `AAD imm' and `AAM imm' are no longer flagged as
+undocumented because the Intel Architecture reference documents
+them.
+
+\b Fixed a problem with the local-label mechanism, whereby strange
+types of symbol (EQUs, auto-defined OBJ segment base symbols)
+interfered with the `previous global label' value and screwed up
+local labels.
+
+\b Fixed a bug whereby the stub preprocessor didn't communicate with
+the listing file generator, so that the -a and -l options in
+conjunction would produce a useless listing file.
+
+\b Merged `os2' object file format back into `obj', after discovering
+that `obj' _also_ shouldn't have a link pass separator in a module
+containing a non-trivial MODEND. Flat segments are now declared
+using the FLAT attribute. `os2' is no longer a valid object format
+name: use `obj'.
+
+\b Removed the fixed-size temporary storage in the evaluator. Very very
+long expressions (like `mov ax,1+1+1+1+...' for two hundred 1s or
+so) should now no longer crash NASM.
+
+\b Fixed a bug involving segfaults on disassembly of MMX instructions,
+by changing the meaning of one of the operand-type flags in nasm.h.
+This may cause other apparently unrelated MMX problems; it needs to
+be tested thoroughly.
+
+\b Fixed some buffer overrun problems with large OBJ output files.
+Thanks to DJ Delorie for the bug report and fix.
+
+\b Made preprocess-only mode actually listen to the %line markers as it
+prints them, so that it can report errors more sanely.
+
+\b Re-designed the evaluator to keep more sensible track of expressions
+involving forward references: can now cope with previously-nightmare
+situations such as:
+
+\c   mov ax,foo | bar
+\c   foo equ 1
+\c   bar equ 2
+
+\b Added the ALIGN and ALIGNB standard macros.
+
+\b Added PIC support in ELF: use of WRT to obtain the four extra
+relocation types needed.
+
+\b Added the ability for output file formats to define their own
+extensions to the GLOBAL, COMMON and EXTERN directives.
+
+\b Implemented common-variable alignment, and global-symbol type and
+size declarations, in ELF.
+
+\b Implemented NEAR and FAR keywords for common variables, plus
+far-common element size specification, in OBJ.
+
+\b Added a feature whereby EXTERNs and COMMONs in OBJ can be given a
+default WRT specification (either a segment or a group).
+
+\b Transformed the Unix NASM archive into an auto-configuring package.
+
+\b Added a sanity-check for people applying SEG to things which are
+already segment bases: this previously went unnoticed by the SEG
+processing and caused OBJ-driver panics later.
+
+\b Added the ability, in OBJ format, to deal with `MOV EAX,<segment>'
+type references: OBJ doesn't directly support dword-size segment
+base fixups, but as long as the low two bytes of the constant term
+are zero, a word-size fixup can be generated instead and it will
+work.
+
+\b Added the ability to specify sections' alignment requirements in
+Win32 object files and pure binary files.
+
+\b Added preprocess-time expression evaluation: the %assign (and
+%iassign) directive and the bare %if (and %elif) conditional. Added
+relational operators to the evaluator, for use only in %if
+constructs: the standard relationals = < > <= >= <> (and C-like
+synonyms == and !=) plus low-precedence logical operators &&, ^^ and
+||.
+
+\b Added a preprocessor repeat construct: %rep / %exitrep / %endrep.
+
+\b Added the __FILE__ and __LINE__ standard macros.
+
+\b Added a sanity check for number constants being greater than
+0xFFFFFFFF. The warning can be disabled.
+
+\b Added the %0 token whereby a variadic multi-line macro can tell how
+many parameters it's been given in a specific invocation.
+
+\b Added \c{%rotate}, allowing multi-line macro parameters to be cycled.
+
+\b Added the `*' option for the maximum parameter count on multi-line
+macros, allowing them to take arbitrarily many parameters.
+
+\b Added the ability for the user-level forms of EXTERN, GLOBAL and
+COMMON to take more than one argument.
+
+\b Added the IMPORT and EXPORT directives in OBJ format, to deal with
+Windows DLLs.
+
+\b Added some more preprocessor %if constructs: %ifidn / %ifidni (exact
+textual identity), and %ifid / %ifnum / %ifstr (token type testing).
+
+\b Added the ability to distinguish SHL AX,1 (the 8086 version) from
+SHL AX,BYTE 1 (the 286-and-upwards version whose constant happens to
+be 1).
+
+\b Added NetBSD/FreeBSD/OpenBSD's variant of a.out format, complete
+with PIC shared library features.
+
+\b Changed NASM's idiosyncratic handling of FCLEX, FDISI, FENI, FINIT,
+FSAVE, FSTCW, FSTENV, and FSTSW to bring it into line with the
+otherwise accepted standard. The previous behaviour, though it was a
+deliberate feature, was a deliberate feature based on a
+misunderstanding. Apologies for the inconvenience.
+
+\b Improved the flexibility of ABSOLUTE: you can now give it an
+expression rather than being restricted to a constant, and it can
+take relocatable arguments as well.
+
+\b Added the ability for a variable to be declared as EXTERN multiple
+times, and the subsequent definitions are just ignored.
+
+\b We now allow instruction prefixes (CS, DS, LOCK, REPZ etc) to be
+alone on a line (without a following instruction).
+
+\b Improved sanity checks on whether the arguments to EXTERN, GLOBAL
+and COMMON are valid identifiers.
+
+\b Added misc/exebin.mac to allow direct generation of .EXE files by
+hacking up an EXE header using DB and DW; also added test/binexe.asm
+to demonstrate the use of this. Thanks to Yann Guidon for
+contributing the EXE header code.
+
+\b ndisasm forgot to check whether the input file had been successfully
+opened. Now it does. Doh!
+
+\b Added the Cyrix extensions to the MMX instruction set.
+
+\b Added a hinting mechanism to allow [EAX+EBX] and [EBX+EAX] to be
+assembled differently. This is important since [ESI+EBP] and
+[EBP+ESI] have different default base segment registers.
+
+\b Added support for the PharLap OMF extension for 4096-byte segment
+alignment.
+
+
+\S{cl-0.95 released July 1997} Version 0.95 released July 1997
+
+\b Fixed yet another ELF bug. This one manifested if the user relied on
+the default segment, and attempted to define global symbols without
+first explicitly declaring the target segment.
+
+\b Added makefiles (for NASM and the RDF tools) to build Win32 console
+apps under Symantec C++. Donated by Mark Junker.
+
+\b Added `macros.bas' and `insns.bas', QBasic versions of the Perl
+scripts that convert `standard.mac' to `macros.c' and convert
+`insns.dat' to `insnsa.c' and `insnsd.c'. Also thanks to Mark
+Junker.
+
+\b Changed the diassembled forms of the conditional instructions so
+that JB is now emitted as JC, and other similar changes. Suggested
+list by Ulrich Doewich.
+
+\b Added `@' to the list of valid characters to begin an identifier
+with.
+
+\b Documentary changes, notably the addition of the `Common Problems'
+section in nasm.doc.
+
+\b Fixed a bug relating to 32-bit PC-relative fixups in OBJ.
+
+\b Fixed a bug in perm_copy() in labels.c which was causing exceptions
+in cleanup_labels() on some systems.
+
+\b Positivity sanity check in TIMES argument changed from a warning to
+an error following a further complaint.
+
+\b Changed the acceptable limits on byte and word operands to allow
+things like `~10111001b' to work.
+
+\b Fixed a major problem in the preprocessor which caused seg-faults if
+macro definitions contained blank lines or comment-only lines.
+
+\b Fixed inadequate error checking on the commas separating the
+arguments to `db', `dw' etc.
+
+\b Fixed a crippling bug in the handling of macros with operand counts
+defined with a `+' modifier.
+
+\b Fixed a bug whereby object file formats which stored the input file
+name in the output file (such as OBJ and COFF) weren't doing so
+correctly when the output file name was specified on the command
+line.
+
+\b Removed [INC] and [INCLUDE] support for good, since they were
+obsolete anyway.
+
+\b Fixed a bug in OBJ which caused all fixups to be output in 16-bit
+(old-format) FIXUPP records, rather than putting the 32-bit ones in
+FIXUPP32 (new-format) records.
+
+\b Added, tentatively, OS/2 object file support (as a minor variant on
+OBJ).
+
+\b Updates to Fox Cutter's Borland C makefile, Makefile.bc2.
+
+\b Removed a spurious second fclose() on the output file.
+
+\b Added the `-s' command line option to redirect all messages which
+would go to stderr (errors, help text) to stdout instead.
+
+\b Added the `-w' command line option to selectively suppress some
+classes of assembly warning messages.
+
+\b Added the `-p' pre-include and `-d' pre-define command-line options.
+
+\b Added an include file search path: the `-i' command line option.
+
+\b Fixed a silly little preprocessor bug whereby starting a line with a
+`%!' environment-variable reference caused an `unknown directive'
+error.
+
+\b Added the long-awaited listing file support: the `-l' command line
+option.
+
+\b Fixed a problem with OBJ format whereby, in the absence of any
+explicit segment definition, non-global symbols declared in the
+implicit default segment generated spurious EXTDEF records in the
+output.
+
+\b Added the NASM environment variable.
+
+\b From this version forward, Win32 console-mode binaries will be
+included in the DOS distribution in addition to the 16-bit binaries.
+Added Makefile.vc for this purpose.
+
+\b Added `return 0;' to test/objlink.c to prevent compiler warnings.
+
+\b Added the __NASM_MAJOR__ and __NASM_MINOR__ standard defines.
+
+\b Added an alternative memory-reference syntax in which prefixing an
+operand with `&' is equivalent to enclosing it in square brackets,
+at the request of Fox Cutter.
+
+\b Errors in pass two now cause the program to return a non-zero error
+code, which they didn't before.
+
+\b Fixed the single-line macro cycle detection, which didn't work at
+all on macros with no parameters (caused an infinite loop). Also
+changed the behaviour of single-line macro cycle detection to work
+like cpp, so that macros like `extrn' as given in the documentation
+can be implemented.
+
+\b Fixed the implementation of WRT, which was too restrictive in that
+you couldn't do `mov ax,[di+abc wrt dgroup]' because (di+abc) wasn't
+a relocatable reference.
+
+
+\S{cl-0.94 released April 1997} Version 0.94 released April 1997
+
+
+\b Major item: added the macro processor.
+
+\b Added undocumented instructions SMI, IBTS, XBTS and LOADALL286. Also
+reorganised CMPXCHG instruction into early-486 and Pentium forms.
+Thanks to Thobias Jones for the information.
+
+\b Fixed two more stupid bugs in ELF, which were causing `ld' to
+continue to seg-fault in a lot of non-trivial cases.
+
+\b Fixed a seg-fault in the label manager.
+
+\b Stopped FBLD and FBSTP from _requiring_ the TWORD keyword, which is
+the only option for BCD loads/stores in any case.
+
+\b Ensured FLDCW, FSTCW and FSTSW can cope with the WORD keyword, if
+anyone bothers to provide it. Previously they complained unless no
+keyword at all was present.
+
+\b Some forms of FDIV/FDIVR and FSUB/FSUBR were still inverted: a
+vestige of a bug that I thought had been fixed in 0.92. This was
+fixed, hopefully for good this time...
+
+\b Another minor phase error (insofar as a phase error can _ever_ be
+minor) fixed, this one occurring in code of the form
+
+\c   rol ax,forward_reference
+\c   forward_reference equ 1
+
+\b The number supplied to TIMES is now sanity-checked for positivity,
+and also may be greater than 64K (which previously didn't work on
+16-bit systems).
+
+\b Added Watcom C makefiles, and misc/pmw.bat, donated by Dominik Behr.
+
+\b Added the INCBIN pseudo-opcode.
+
+\b Due to the advent of the preprocessor, the [INCLUDE] and [INC]
+directives have become obsolete. They are still supported in this
+version, with a warning, but won't be in the next.
+
+\b Fixed a bug in OBJ format, which caused incorrect object records to
+be output when absolute labels were made global.
+
+\b Updates to RDOFF subdirectory, and changes to outrdf.c.
+
+
+\S{cl-0.93 released January 1997} Version 0.93 released January 1997
+
+This release went out in a great hurry after semi-crippling bugs
+were found in 0.92.
+
+\b Really \e{did} fix the stack overflows this time. *blush*
+
+\b Had problems with EA instruction sizes changing between passes, when
+an offset contained a forward reference and so 4 bytes were
+allocated for the offset in pass one; by pass two the symbol had
+been defined and happened to be a small absolute value, so only 1
+byte got allocated, causing instruction size mismatch between passes
+and hence incorrect address calculations. Fixed.
+
+\b Stupid bug in the revised ELF section generation fixed (associated
+string-table section for .symtab was hard-coded as 7, even when this
+didn't fit with the real section table). Was causing `ld' to
+seg-fault under Linux.
+
+\b Included a new Borland C makefile, Makefile.bc2, donated by Fox
+Cutter <lmb@comtch.iea.com>.
+
+
+\S{cl-0.92 released January 1997} Version 0.92 released January 1997
+
+\b The FDIVP/FDIVRP and FSUBP/FSUBRP pairs had been inverted: this was
+fixed. This also affected the LCC driver.
+
+\b Fixed a bug regarding 32-bit effective addresses of the form
+\c{[other_register+ESP]}.
+
+\b Documentary changes, notably documentation of the fact that Borland
+Win32 compilers use `obj' rather than `win32' object format.
+
+\b Fixed the COMENT record in OBJ files, which was formatted
+incorrectly.
+
+\b Fixed a bug causing segfaults in large RDF files.
+
+\b OBJ format now strips initial periods from segment and group
+definitions, in order to avoid complications with the local label
+syntax.
+
+\b Fixed a bug in disassembling far calls and jumps in NDISASM.
+
+\b Added support for user-defined sections in COFF and ELF files.
+
+\b Compiled the DOS binaries with a sensible amount of stack, to
+prevent stack overflows on any arithmetic expression containing
+parentheses.
+
+\b Fixed a bug in handling of files that do not terminate in a newline.
+
+
+\S{cl-0.91 released November 1996} Version 0.91 released November 1996
+
+\b Loads of bug fixes.
+
+\b Support for RDF added.
+
+\b Support for DBG debugging format added.
+
+\b Support for 32-bit extensions to Microsoft OBJ format added.
+
+\b Revised for Borland C: some variable names changed, makefile added.
+
+\b LCC support revised to actually work.
+
+\b JMP/CALL NEAR/FAR notation added.
+
+\b `a16', `o16', `a32' and `o32' prefixes added.
+
+\b Range checking on short jumps implemented.
+
+\b MMX instruction support added.
+
+\b Negative floating point constant support added.
+
+\b Memory handling improved to bypass 64K barrier under DOS.
+
+\b \c{$} prefix to force treatment of reserved words as identifiers added.
+
+\b Default-size mechanism for object formats added.
+
+\b Compile-time configurability added.
+
+\b \c{#}, \c{@}, \c{~} and c\{?} are now valid characters in labels.
+
+\b \c{-e} and \c{-k} options in NDISASM added.
+
+
+\S{cl-0.90 released October 1996} Version 0.90 released October 1996
+
+First release version. First support for object file output. Other
+changes from previous version (0.3x) too numerous to document.
