9.1.3. Accessing Data Items
---------------------------

To get at the contents of C variables, or to declare variables which C
can access, you need only declare the names as `GLOBAL' or `EXTERN'.
(Again, the names require leading underscores, as stated in *note
Section 9.1.1::.) Thus, a C variable declared as `int i' can be
accessed from assembler as

               extern _i
               mov eax,[_i]

   And to declare your own integer variable which C programs can access
as `extern int j', you do this (making sure you are assembling in the
`_DATA' segment, if necessary):

               global _j
     _j        dd 0

   To access a C array, you need to know the size of the components of
the array. For example, `int' variables are four bytes long, so if a C
program declares an array as `int a[10]', you can access `a[3]' by
coding `mov ax,[_a+12]'. (The byte offset 12 is obtained by multiplying
the desired array index, 3, by the size of the array element, 4.) The
sizes of the C base types in 32-bit compilers are: 1 for `char', 2 for
`short', 4 for `int', `long' and `float', and 8 for `double'. Pointers,
being 32-bit addresses, are also 4 bytes long.

   To access a C data structure, you need to know the offset from the
base of the structure to the field you are interested in. You can
either do this by converting the C structure definition into a NASM
structure definition (using `STRUC'), or by calculating the one offset
and using just that.

   To do either of these, you should read your C compiler's manual to
find out how it organizes data structures. NASM gives no special
alignment to structure members in its own `STRUC' macro, so you have to
specify alignment yourself if the C compiler generates it. Typically,
you might find that a structure like

     struct {
         char c;
         int i;
     } foo;

   might be eight bytes long rather than five, since the `int' field
would be aligned to a four-byte boundary. However, this sort of feature
is sometimes a configurable option in the C compiler, either using
command- line options or `#pragma' lines, so you have to find out how
your own compiler does it.

9.1.4. `c32.mac': Helper Macros for the 32-bit C Interface
----------------------------------------------------------

Included in the NASM archives, in the `misc' directory, is a file
`c32.mac' of macros. It defines three macros: `proc', `arg' and
`endproc'. These are intended to be used for C-style procedure
definitions, and they automate a lot of the work involved in keeping
track of the calling convention.

   An example of an assembly function using the macro set is given here:

     proc    _proc32

     %$i     arg
     %$j     arg
             mov     eax,[ebp + %$i]
             mov     ebx,[ebp + %$j]
             add     eax,[ebx]

     endproc

   This defines `_proc32' to be a procedure taking two arguments, the
first (`i') an integer and the second (`j') a pointer to an integer. It
returns `i + *j'.

   Note that the `arg' macro has an `EQU' as the first line of its
expansion, and since the label before the macro call gets prepended to
the first line of the expanded macro, the `EQU' works, defining `%$i'
to be an offset from `BP'. A context-local variable is used, local to
the context pushed by the `proc' macro and popped by the `endproc'
macro, so that the same argument name can be used in later procedures.
Of course, you don't _have_ to do that.

   `arg' can take an optional parameter, giving the size of the
argument.  If no size is given, 4 is assumed, since it is likely that
many function parameters will be of type `int' or pointers.

9.2. Writing NetBSD/FreeBSD/OpenBSD and Linux/ELF Shared Libraries
==================================================================

`ELF' replaced the older `a.out' object file format under Linux because
it contains support for position-independent code (PIC), which makes
writing shared libraries much easier. NASM supports the `ELF'
position-independent code features, so you can write Linux `ELF' shared
libraries in NASM.

   NetBSD, and its close cousins FreeBSD and OpenBSD, take a different
approach by hacking PIC support into the `a.out' format. NASM supports
this as the `aoutb' output format, so you can write BSD shared
libraries in NASM too.

   The operating system loads a PIC shared library by memory-mapping the
library file at an arbitrarily chosen point in the address space of the
running process. The contents of the library's code section must
therefore not depend on where it is loaded in memory.

   Therefore, you cannot get at your variables by writing code like
this:

             mov     eax,[myvar]             ; WRONG

   Instead, the linker provides an area of memory called the _global
offset table_, or GOT; the GOT is situated at a constant distance from
your library's code, so if you can find out where your library is
loaded (which is typically done using a `CALL' and `POP' combination),
you can obtain the address of the GOT, and you can then load the
addresses of your variables out of linker-generated entries in the GOT.

   The _data_ section of a PIC shared library does not have these
restrictions: since the data section is writable, it has to be copied
into memory anyway rather than just paged in from the library file, so
as long as it's being copied it can be relocated too. So you can put
ordinary types of relocation in the data section without too much worry
(but see *note Section 9.2.4:: for a caveat).

* Section 9.2.6:: Generating the Library File


File: nasm.info,  Node: Section 9.2.1,  Next: Section 9.2.2,  Prev: Section 9.2,  Up: Section 9.2

9.2.1. Obtaining the Address of the GOT
---------------------------------------

Each code module in your shared library should define the GOT as an
external symbol:

     extern  _GLOBAL_OFFSET_TABLE_   ; in ELF
     extern  __GLOBAL_OFFSET_TABLE_  ; in BSD a.out

   At the beginning of any function in your shared library which plans
to access your data or BSS sections, you must first calculate the
address of the GOT. This is typically done by writing the function in
this form:

     func:   push    ebp
             mov     ebp,esp
             push    ebx
             call    .get_GOT
     .get_GOT:
             pop     ebx
             add     ebx,_GLOBAL_OFFSET_TABLE_+$$-.get_GOT wrt ..gotpc

             ; the function body comes here

             mov     ebx,[ebp-4]
             mov     esp,ebp
             pop     ebp
             ret

   (For BSD, again, the symbol `_GLOBAL_OFFSET_TABLE' requires a second
leading underscore.)

   The first two lines of this function are simply the standard C
prologue to set up a stack frame, and the last three lines are standard
C function epilogue. The third line, and the fourth to last line, save
and restore the `EBX' register, because PIC shared libraries use this
register to store the address of the GOT.

   The interesting bit is the `CALL' instruction and the following two
lines. The `CALL' and `POP' combination obtains the address of the
label `.get_GOT', without having to know in advance where the program
was loaded (since the `CALL' instruction is encoded relative to the
current position). The `ADD' instruction makes use of one of the
special PIC relocation types: GOTPC relocation. With the `WRT ..gotpc'
qualifier specified, the symbol referenced (here
`_GLOBAL_OFFSET_TABLE_', the special symbol assigned to the GOT) is
given as an offset from the beginning of the section. (Actually, `ELF'
encodes it as the offset from the operand field of the `ADD'
instruction, but NASM simplifies this deliberately, so you do things the
same way for both `ELF' and `BSD'.) So the instruction then _adds_ the
beginning of the section, to get the real address of the GOT, and
subtracts the value of `.get_GOT' which it knows is in `EBX'.
Therefore, by the time that instruction has finished, `EBX' contains
the address of the GOT.

   If you didn't follow that, don't worry: it's never necessary to
obtain the address of the GOT by any other means, so you can put those
three instructions into a macro and safely ignore them:

     %macro  get_GOT 0

             call    %%getgot
       %%getgot:
             pop     ebx
             add     ebx,_GLOBAL_OFFSET_TABLE_+$$-%%getgot wrt ..gotpc

     %endmacro

9.2.2. Finding Your Local Data Items
------------------------------------

Having got the GOT, you can then use it to obtain the addresses of your
data items. Most variables will reside in the sections you have
declared; they can be accessed using the `..gotoff' special `WRT' type.
The way this works is like this:

             lea     eax,[ebx+myvar wrt ..gotoff]

   The expression `myvar wrt ..gotoff' is calculated, when the shared
library is linked, to be the offset to the local variable `myvar' from
the beginning of the GOT. Therefore, adding it to `EBX' as above will
place the real address of `myvar' in `EAX'.

   If you declare variables as `GLOBAL' without specifying a size for
them, they are shared between code modules in the library, but do not
get exported from the library to the program that loaded it. They will
still be in your ordinary data and BSS sections, so you can access them
in the same way as local variables, using the above `..gotoff'
mechanism.

   Note that due to a peculiarity of the way BSD `a.out' format handles
this relocation type, there must be at least one non-local symbol in the
same section as the address you're trying to access.


File: nasm.info,  Node: Section 9.2.3,  Next: Section 9.2.4,  Prev: Section 9.2.2,  Up: Section 9.2

9.2.3. Finding External and Common Data Items
---------------------------------------------

If your library needs to get at an external variable (external to the
_library_, not just to one of the modules within it), you must use the
`..got' type to get at it. The `..got' type, instead of giving you the
offset from the GOT base to the variable, gives you the offset from the
GOT base to a GOT _entry_ containing the address of the variable.  The
linker will set up this GOT entry when it builds the library, and the
dynamic linker will place the correct address in it at load time. So to
obtain the address of an external variable `extvar' in `EAX', you would
code

             mov     eax,[ebx+extvar wrt ..got]

   This loads the address of `extvar' out of an entry in the GOT. The
linker, when it builds the shared library, collects together every
relocation of type `..got', and builds the GOT so as to ensure it has
every necessary entry present.

   Common variables must also be accessed in this way.


File: nasm.info,  Node: Section 9.2.4,  Next: Section 9.2.5,  Prev: Section 9.2.3,  Up: Section 9.2

9.2.4. Exporting Symbols to the Library User
--------------------------------------------

If you want to export symbols to the user of the library, you have to
declare whether they are functions or data, and if they are data, you
have to give the size of the data item. This is because the dynamic
linker has to build procedure linkage table entries for any exported
functions, and also moves exported data items away from the library's
data section in which they were declared.

   So to export a function to users of the library, you must use

     global  func:function           ; declare it as a function

     func:   push    ebp

             ; etc.

   And to export a data item such as an array, you would have to code

     global  array:data array.end-array      ; give the size too

     array:  resd    128
     .end:

   Be careful: If you export a variable to the library user, by
declaring it as `GLOBAL' and supplying a size, the variable will end up
living in the data section of the main program, rather than in your
library's data section, where you declared it. So you will have to
access your own global variable with the `..got' mechanism rather than
`..gotoff', as if it were external (which, effectively, it has become).

   Equally, if you need to store the address of an exported global in
one of your data sections, you can't do it by means of the standard
sort of code:

     dataptr:        dd      global_data_item        ; WRONG

   NASM will interpret this code as an ordinary relocation, in which
`global_data_item' is merely an offset from the beginning of the
`.data' section (or whatever); so this reference will end up pointing
at your data section instead of at the exported global which resides
elsewhere.

   Instead of the above code, then, you must write

     dataptr:        dd      global_data_item wrt ..sym

   which makes use of the special `WRT' type `..sym' to instruct NASM
to search the symbol table for a particular symbol at that address,
rather than just relocating by section base.

   Either method will work for functions: referring to one of your
functions by means of

     funcptr:        dd      my_function

   will give the user the address of the code you wrote, whereas

     funcptr:        dd      my_function wrt .sym

   will give the address of the procedure linkage table for the
function, which is where the calling program will _believe_ the
function lives.  Either address is a valid way to call the function.

9.2.5. Calling Procedures Outside the Library
---------------------------------------------

Calling procedures outside your shared library has to be done by means
of a _procedure linkage table_, or PLT. The PLT is placed at a known
offset from where the library is loaded, so the library code can make
calls to the PLT in a position-independent way. Within the PLT there is
code to jump to offsets contained in the GOT, so function calls to
other shared libraries or to routines in the main program can be
transparently passed off to their real destinations.

   To call an external routine, you must use another special PIC
relocation type, `WRT ..plt'. This is much easier than the GOT-based
ones: you simply replace calls such as `CALL printf' with the
PLT-relative version `CALL printf WRT ..plt'.

9.2.6. Generating the Library File
----------------------------------

Having written some code modules and assembled them to `.o' files, you
then generate your shared library with a command such as

     ld -shared -o library.so module1.o module2.o       # for ELF
     ld -Bshareable -o library.so module1.o module2.o   # for BSD

   For ELF, if your shared library is going to reside in system
directories such as `/usr/lib' or `/lib', it is usually worth using the
`-soname' flag to the linker, to store the final library file name,
with a version number, into the library:

     ld -shared -soname library.so.1 -o library.so.1.2 *.o

   You would then copy `library.so.1.2' into the library directory, and
create `library.so.1' as a symbolic link to it.

Chapter 10: Mixing 16 and 32 Bit Code
*************************************

This chapter tries to cover some of the issues, largely related to
unusual forms of addressing and jump instructions, encountered when
writing operating system code such as protected-mode initialisation
routines, which require code that operates in mixed segment sizes, such
as code in a 16-bit segment trying to modify data in a 32-bit one, or
jumps between different- size segments.

* Menu:

* Section 10.1:: Mixed-Size Jumps
* Section 10.2:: Addressing Between Different-Size Segments
* Section 10.3:: Other Mixed-Size Instructions


File: nasm.info,  Node: Section 10.1,  Next: Section 10.2,  Prev: Chapter 10,  Up: Chapter 10

10.1. Mixed-Size Jumps
======================

The most common form of mixed-size instruction is the one used when
writing a 32-bit OS: having done your setup in 16-bit mode, such as
loading the kernel, you then have to boot it by switching into
protected mode and jumping to the 32-bit kernel start address. In a
fully 32-bit OS, this tends to be the _only_ mixed-size instruction you
need, since everything before it can be done in pure 16-bit code, and
everything after it can be pure 32-bit.

   This jump must specify a 48-bit far address, since the target
segment is a 32-bit one. However, it must be assembled in a 16-bit
segment, so just coding, for example,

             jmp     0x1234:0x56789ABC       ; wrong!

   will not work, since the offset part of the address will be
truncated to `0x9ABC' and the jump will be an ordinary 16-bit far one.

   The Linux kernel setup code gets round the inability of `as86' to
generate the required instruction by coding it manually, using `DB'
instructions. NASM can go one better than that, by actually generating
the right instruction itself. Here's how to do it right:

             jmp     dword 0x1234:0x56789ABC         ; right

   The `DWORD' prefix (strictly speaking, it should come _after_ the
colon, since it is declaring the _offset_ field to be a doubleword; but
NASM will accept either form, since both are unambiguous) forces the
offset part to be treated as far, in the assumption that you are
deliberately writing a jump from a 16-bit segment to a 32-bit one.

   You can do the reverse operation, jumping from a 32-bit segment to a
16-bit one, by means of the `WORD' prefix:

             jmp     word 0x8765:0x4321      ; 32 to 16 bit

   If the `WORD' prefix is specified in 16-bit mode, or the `DWORD'
prefix in 32-bit mode, they will be ignored, since each is explicitly
forcing NASM into a mode it was in anyway.


File: nasm.info,  Node: Section 10.2,  Next: Section 10.3,  Prev: Section 10.1,  Up: Chapter 10

10.2. Addressing Between Different-Size Segments
================================================

If your OS is mixed 16 and 32-bit, or if you are writing a DOS extender,
you are likely to have to deal with some 16-bit segments and some 32-bit
ones. At some point, you will probably end up writing code in a 16-bit
segment which has to access data in a 32-bit segment, or vice versa.

   If the data you are trying to access in a 32-bit segment lies within
the first 64K of the segment, you may be able to get away with using an
ordinary 16-bit addressing operation for the purpose; but sooner or
later, you will want to do 32-bit addressing from 16-bit mode.

   The easiest way to do this is to make sure you use a register for the
address, since any effective address containing a 32-bit register is
forced to be a 32-bit address. So you can do

             mov     eax,offset_into_32_bit_segment_specified_by_fs
             mov     dword [fs:eax],0x11223344

   This is fine, but slightly cumbersome (since it wastes an
instruction and a register) if you already know the precise offset you
are aiming at. The x86 architecture does allow 32-bit effective
addresses to specify nothing but a 4-byte offset, so why shouldn't NASM
be able to generate the best instruction for the purpose?

   It can. As in *note Section 10.1::, you need only prefix the address
with the `DWORD' keyword, and it will be forced to be a 32-bit address:

             mov     dword [fs:dword my_offset],0x11223344

   Also as in *note Section 10.1::, NASM is not fussy about whether the
`DWORD' prefix comes before or after the segment override, so arguably
a nicer-looking way to code the above instruction is

             mov     dword [dword fs:my_offset],0x11223344

   Don't confuse the `DWORD' prefix _outside_ the square brackets,
which controls the size of the data stored at the address, with the one
`inside' the square brackets which controls the length of the address
itself. The two can quite easily be different:

             mov     word [dword 0x12345678],0x9ABC

   This moves 16 bits of data to an address specified by a 32-bit
offset.

   You can also specify `WORD' or `DWORD' prefixes along with the `FAR'
prefix to indirect far jumps or calls. For example:

             call    dword far [fs:word 0x4321]

   This instruction contains an address specified by a 16-bit offset;
it loads a 48-bit far pointer from that (16-bit segment and 32-bit
offset), and calls that address.


File: nasm.info,  Node: Section 10.3,  Next: Chapter 11,  Prev: Section 10.2,  Up: Chapter 10

10.3. Other Mixed-Size Instructions
===================================

The other way you might want to access data might be using the string
instructions (`LODSx', `STOSx' and so on) or the `XLATB' instruction.
These instructions, since they take no parameters, might seem to have
no easy way to make them perform 32-bit addressing when assembled in a
16-bit segment.

   This is the purpose of NASM's `a16', `a32' and `a64' prefixes. If
you are coding `LODSB' in a 16-bit segment but it is supposed to be
accessing a string in a 32-bit segment, you should load the desired
address into `ESI' and then code

             a32     lodsb

   The prefix forces the addressing size to 32 bits, meaning that
`LODSB' loads from `[DS:ESI]' instead of `[DS:SI]'. To access a string
in a 16-bit segment when coding in a 32-bit one, the corresponding `a16'
prefix can be used.

   The `a16', `a32' and `a64' prefixes can be applied to any
instruction in NASM's instruction table, but most of them can generate
all the useful forms without them. The prefixes are necessary only for
instructions with implicit addressing: `CMPSx', `SCASx', `LODSx',
`STOSx', `MOVSx', `INSx', `OUTSx', and `XLATB'. Also, the various push
and pop instructions (`PUSHA' and `POPF' as well as the more usual
`PUSH' and `POP') can accept `a16', `a32' or `a64' prefixes to force a
particular one of `SP', `ESP' or `RSP' to be used as a stack pointer,
in case the stack segment in use is a different size from the code
segment.

   `PUSH' and `POP', when applied to segment registers in 32-bit mode,
also have the slightly odd behaviour that they push and pop 4 bytes at
a time, of which the top two are ignored and the bottom two give the
value of the segment register being manipulated. To force the 16-bit
behaviour of segment-register push and pop instructions, you can use the
operand-size prefix `o16':

             o16 push    ss
             o16 push    ds

   This code saves a doubleword of stack space by fitting two segment
registers into the space which would normally be consumed by pushing
one.

   (You can also use the `o32' prefix to force the 32-bit behaviour when
in 16-bit mode, but this seems less useful.)

Chapter 11: Writing 64-bit Code (Unix, Win64)
*********************************************

This chapter attempts to cover some of the common issues involved when
writing 64-bit code, to run under Win64 or Unix. It covers how to write
assembly code to interface with 64-bit C routines, and how to write
position-independent code for shared libraries.

   All 64-bit code uses a flat memory model, since segmentation is not
available in 64-bit mode. The one exception is the `FS' and `GS'
registers, which still add their bases.

   Position independence in 64-bit mode is significantly simpler, since
the processor supports `RIP'-relative addressing directly; see the
`REL' keyword (*note Section 3.3::). On most 64-bit platforms, it is
probably desirable to make that the default, using the directive
`DEFAULT REL' (*note Section 6.2::).

   64-bit programming is relatively similar to 32-bit programming, but
of course pointers are 64 bits long; additionally, all existing
platforms pass arguments in registers rather than on the stack.
Furthermore, 64-bit platforms use SSE2 by default for floating point.
Please see the ABI documentation for your platform.

   64-bit platforms differ in the sizes of the fundamental datatypes,
not just from 32-bit platforms but from each other. If a specific size
data type is desired, it is probably best to use the types defined in
the Standard C header `<inttypes.h>'.

   In 64-bit mode, the default instruction size is still 32 bits. When
loading a value into a 32-bit register (but not an 8- or 16-bit
register), the upper 32 bits of the corresponding 64-bit register are
set to zero.

11.1. Register Names in 64-bit Mode
===================================

NASM uses the following names for general-purpose registers in 64-bit
mode, for 8-, 16-, 32- and 64-bit references, respecitively:

          AL/AH, CL/CH, DL/DH, BL/BH, SPL, BPL, SIL, DIL, R8B-R15B
          AX, CX, DX, BX, SP, BP, SI, DI, R8W-R15W
          EAX, ECX, EDX, EBX, ESP, EBP, ESI, EDI, R8D-R15D
          RAX, RCX, RDX, RBX, RSP, RBP, RSI, RDI, R8-R15

   This is consistent with the AMD documentation and most other
assemblers.  The Intel documentation, however, uses the names
`R8L-R15L' for 8-bit references to the higher registers. It is possible
to use those names by definiting them as macros; similarly, if one
wants to use numeric names for the low 8 registers, define them as
macros. The standard macro package `altreg' (see *note Section 5.1::)
can be used for this purpose.

11.2. Immediates and Displacements in 64-bit Mode
=================================================

In 64-bit mode, immediates and displacements are generally only 32 bits
wide. NASM will therefore truncate most displacements and immediates to
32 bits.

   The only instruction which takes a full 64-bit immediate is:

          MOV reg64,imm64

   NASM will produce this instruction whenever the programmer uses `MOV'
with an immediate into a 64-bit register. If this is not desirable,
simply specify the equivalent 32-bit register, which will be
automatically zero- extended by the processor, or specify the immediate
as `DWORD':

          mov rax,foo             ; 64-bit immediate
          mov rax,qword foo       ; (identical)
          mov eax,foo             ; 32-bit immediate, zero-extended
          mov rax,dword foo       ; 32-bit immediate, sign-extended

   The length of these instructions are 10, 5 and 7 bytes, respectively.

   The only instructions which take a full 64-bit _displacement_ is
loading or storing, using `MOV', `AL', `AX', `EAX' or `RAX' (but no
other registers) to an absolute 64-bit address. Since this is a
relatively rarely used instruction (64-bit code generally uses relative
addressing), the programmer has to explicitly declare the displacement
size as `QWORD':

          default abs

          mov eax,[foo]           ; 32-bit absolute disp, sign-extended
          mov eax,[a32 foo]       ; 32-bit absolute disp, zero-extended
          mov eax,[qword foo]     ; 64-bit absolute disp

          default rel

          mov eax,[foo]           ; 32-bit relative disp
          mov eax,[a32 foo]       ; d:o, address truncated to 32 bits(!)
          mov eax,[qword foo]     ; error
          mov eax,[abs qword foo] ; 64-bit absolute disp

   A sign-extended absolute displacement can access from -2 GB to +2
GB; a zero-extended absolute displacement can access from 0 to 4 GB.

11.3. Interfacing to 64-bit C Programs (Unix)
=============================================

On Unix, the 64-bit ABI is defined by the document:

   `http://www.x86-64.org/documentation/abi.pdf'

   Although written for AT&T-syntax assembly, the concepts apply
equally well for NASM-style assembly. What follows is a simplified
summary.

   The first six integer arguments (from the left) are passed in `RDI',
`RSI', `RDX', `RCX', `R8', and `R9', in that order. Additional integer
arguments are passed on the stack. These registers, plus `RAX', `R10'
and `R11' are destroyed by function calls, and thus are available for
use by the function without saving.

   Integer return values are passed in `RAX' and `RDX', in that order.

   Floating point is done using SSE registers, except for `long double'.
Floating-point arguments are passed in `XMM0' to `XMM7'; return is
`XMM0' and `XMM1'. `long double' are passed on the stack, and returned
in `ST0' and `ST1'.

   All SSE and x87 registers are destroyed by function calls.

   On 64-bit Unix, `long' is 64 bits.

   Integer and SSE register arguments are counted separately, so for
the case of

          void foo(long a, double b, int c)

   `a' is passed in `RDI', `b' in `XMM0', and `c' in `ESI'.

11.4. Interfacing to 64-bit C Programs (Win64)
==============================================

The Win64 ABI is described at:

   `http://msdn2.microsoft.com/en-gb/library/ms794533.aspx'

   What follows is a simplified summary.

   The first four integer arguments are passed in `RCX', `RDX', `R8'
and `R9', in that order. Additional integer arguments are passed on the
stack. These registers, plus `RAX', `R10' and `R11' are destroyed by
function calls, and thus are available for use by the function without
saving.

   Integer return values are passed in `RAX' only.

   Floating point is done using SSE registers, except for `long double'.
Floating-point arguments are passed in `XMM0' to `XMM3'; return is
`XMM0' only.

   On Win64, `long' is 32 bits; `long long' or `_int64' is 64 bits.

   Integer and SSE register arguments are counted together, so for the
case of

          void foo(long long a, double b, int c)

   `a' is passed in `RCX', `b' in `XMM1', and `c' in `R8D'.

This chapter describes some of the common problems that users have been
known to encounter with NASM, and answers them. It also gives
instructions for reporting bugs in NASM if you find a difficulty that
isn't listed here.

12.1.1. NASM Generates Inefficient Code
---------------------------------------

We sometimes get `bug' reports about NASM generating inefficient, or
even `wrong', code on instructions such as `ADD ESP,8'. This is a
deliberate design feature, connected to predictability of output: NASM,
on seeing `ADD ESP,8', will generate the form of the instruction which
leaves room for a 32-bit offset. You need to code `ADD ESP,BYTE 8' if
you want the space-efficient form of the instruction. This isn't a bug,
it's user error: if you prefer to have NASM produce the more efficient
code automatically enable optimization with the `-O' option (see *note
Section 2.1.22::).


File: nasm.info,  Node: Section 12.1.2,  Next: Section 12.1.3,  Prev: Section 12.1.1,  Up: Section 12.1

12.1.2. My Jumps are Out of Range
---------------------------------

Similarly, people complain that when they issue conditional jumps (which
are `SHORT' by default) that try to jump too far, NASM reports `short
jump out of range' instead of making the jumps longer.

   This, again, is partly a predictability issue, but in fact has a more
practical reason as well. NASM has no means of being told what type of
processor the code it is generating will be run on; so it cannot decide
for itself that it should generate `Jcc NEAR' type instructions, because
it doesn't know that it's working for a 386 or above. Alternatively, it
could replace the out-of-range short `JNE' instruction with a very
short `JE' instruction that jumps over a `JMP NEAR'; this is a sensible
solution for processors below a 386, but hardly efficient on processors
which have good branch prediction _and_ could have used `JNE NEAR'
instead. So, once again, it's up to the user, not the assembler, to
decide what instructions should be generated. See *note Section
2.1.22::.


File: nasm.info,  Node: Section 12.1.3,  Next: Section 12.1.4,  Prev: Section 12.1.2,  Up: Section 12.1

12.1.3. `ORG' Doesn't Work
--------------------------

People writing boot sector programs in the `bin' format often complain
that `ORG' doesn't work the way they'd like: in order to place the
`0xAA55' signature word at the end of a 512-byte boot sector, people
who are used to MASM tend to code

             ORG 0

             ; some boot sector code

             ORG 510
             DW 0xAA55

   This is not the intended use of the `ORG' directive in NASM, and will
not work. The correct way to solve this problem in NASM is to use the
`TIMES' directive, like this:

             ORG 0

             ; some boot sector code

             TIMES 510-($-$$) DB 0
             DW 0xAA55

   The `TIMES' directive will insert exactly enough zero bytes into the
output to move the assembly point up to 510. This method also has the
advantage that if you accidentally fill your boot sector too full, NASM
will catch the problem at assembly time and report it, so you won't end
up with a boot sector that you have to disassemble to find out what's
wrong with it.


File: nasm.info,  Node: Section 12.1.4,  Next: Section 12.2,  Prev: Section 12.1.3,  Up: Section 12.1

12.1.4. `TIMES' Doesn't Work
----------------------------

The other common problem with the above code is people who write the
`TIMES' line as

             TIMES 510-$ DB 0

   by reasoning that `$' should be a pure number, just like 510, so the
difference between them is also a pure number and can happily be fed to
`TIMES'.

   NASM is a _modular_ assembler: the various component parts are
designed to be easily separable for re-use, so they don't exchange
information unnecessarily. In consequence, the `bin' output format,
even though it has been told by the `ORG' directive that the `.text'
section should start at 0, does not pass that information back to the
expression evaluator. So from the evaluator's point of view, `$' isn't
a pure number: it's an offset from a section base. Therefore the
difference between `$' and 510 is also not a pure number, but involves
a section base. Values involving section bases cannot be passed as
arguments to `TIMES'.

   The solution, as in the previous section, is to code the `TIMES' line
in the form

             TIMES 510-($-$$) DB 0

   in which `$' and `$$' are offsets from the same section base, and so
their difference is a pure number. This will solve the problem and
generate sensible code.

12.2. Bugs
==========

We have never yet released a version of NASM with any _known_ bugs.
That doesn't usually stop there being plenty we didn't know about,
though.  Any that you find should be reported firstly via the
`bugtracker' at `https://sourceforge.net/projects/nasm/' (click on
"Bugs"), or if that fails then through one of the contacts in *note
Section 1.2::.

   Please read *note Section 2.2:: first, and don't report the bug if
it's listed in there as a deliberate feature. (If you think the feature
is badly thought out, feel free to send us reasons why you think it
should be changed, but don't just send us mail saying `This is a bug'
if the documentation says we did it on purpose.) Then read *note
Section 12.1::, and don't bother reporting the bug if it's listed there.

   If you do report a bug, _please_ give us all of the following
information:

   * What operating system you're running NASM under. DOS, Linux,
     NetBSD, Win16, Win32, VMS (I'd be impressed), whatever.

   * If you're running NASM under DOS or Win32, tell us whether you've
     compiled your own executable from the DOS source archive, or
     whether you were using the standard distribution binaries out of
     the archive. If you were using a locally built executable, try to
     reproduce the problem using one of the standard binaries, as this
     will make it easier for us to reproduce your problem prior to
     fixing it.

   * Which version of NASM you're using, and exactly how you invoked
     it. Give us the precise command line, and the contents of the
     `NASMENV' environment variable if any.

   * Which versions of any supplementary programs you're using, and how
     you invoked them. If the problem only becomes visible at link
     time, tell us what linker you're using, what version of it you've
     got, and the exact linker command line. If the problem involves
     linking against object files generated by a compiler, tell us what
     compiler, what version, and what command line or options you used.
     (If you're compiling in an IDE, please try to reproduce the
     problem with the command-line version of the compiler.)

   * If at all possible, send us a NASM source file which exhibits the
     problem.  If this causes copyright problems (e.g. you can only
     reproduce the bug in restricted-distribution code) then bear in
     mind the following two points: firstly, we guarantee that any
     source code sent to us for the purposes of debugging NASM will be
     used _only_ for the purposes of debugging NASM, and that we will
     delete all our copies of it as soon as we have found and fixed the
     bug or bugs in question; and secondly, we would prefer _not_ to be
     mailed large chunks of code anyway. The smaller the file, the
     better.  A three-line sample file that does nothing useful
     _except_ demonstrate the problem is much easier to work with than
     a fully fledged ten-thousand- line program. (Of course, some
     errors _do_ only crop up in large files, so this may not be
     possible.)

   * A description of what the problem actually _is_. `It doesn't work'
     is _not_ a helpful description! Please describe exactly what is
     happening that shouldn't be, or what isn't happening that should.
     Examples might be: `NASM generates an error message saying Line 3
     for an error that's actually on Line 5'; `NASM generates an error
     message that I believe it shouldn't be generating at all'; `NASM
     fails to generate an error message that I believe it _should_ be
     generating'; `the object file produced from this source code
     crashes my linker'; `the ninth byte of the output file is 66 and I
     think it should be 77 instead'.

   * If you believe the output file from NASM to be faulty, send it to
     us. That allows us to determine whether our own copy of NASM
     generates the same file, or whether the problem is related to
     portability issues between our development platforms and yours. We
     can handle binary files mailed to us as MIME attachments,
     uuencoded, and even BinHex. Alternatively, we may be able to
     provide an FTP site you can upload the suspect files to; but
     mailing them is easier for us.

   * Any other information or data files that might be helpful. If, for
     example, the problem involves NASM failing to generate an object
     file while TASM can generate an equivalent file without trouble,
     then send us _both_ object files, so we can see what TASM is doing
     differently from us.

File: nasm.info,  Node: Section A.1,  Next: Section A.2,  Prev: Appendix A,  Up: Appendix A

A.1. Introduction
=================

The Netwide Disassembler is a small companion program to the Netwide
Assembler, NASM. It seemed a shame to have an x86 assembler, complete
with a full instruction table, and not make as much use of it as
possible, so here's a disassembler which shares the instruction table
(and some other bits of code) with NASM.

   The Netwide Disassembler does nothing except to produce
disassemblies of _binary_ source files. NDISASM does not have any
understanding of object file formats, like `objdump', and it will not
understand `DOS .EXE' files like `debug' will. It just disassembles.


File: nasm.info,  Node: Section A.2,  Next: Section A.3,  Prev: Section A.1,  Up: Appendix A

A.2. Getting Started: Installation
==================================

See *note Section 1.3:: for installation instructions. NDISASM, like
NASM, has a `man page' which you may want to put somewhere useful, if
you are on a Unix system.


File: nasm.info,  Node: Section A.3,  Next: Section A.3.1,  Prev: Section A.2,  Up: Appendix A

A.3. Running NDISASM
====================

To disassemble a file, you will typically use a command of the form

            ndisasm -b {16|32|64} filename

   NDISASM can disassemble 16-, 32- or 64-bit code equally easily,
provided of course that you remember to specify which it is to work
with. If no `-b' switch is present, NDISASM works in 16-bit mode by
default. The `-u' switch (for USE32) also invokes 32-bit mode.

   Two more command line options are `-r' which reports the version
number of NDISASM you are running, and `-h' which gives a short summary
of command line options.

File: nasm.info,  Node: Section A.3.1,  Next: Section A.3.2,  Prev: Section A.3,  Up: Section A.3

A.3.1. COM Files: Specifying an Origin
--------------------------------------

To disassemble a `DOS .COM' file correctly, a disassembler must assume
that the first instruction in the file is loaded at address `0x100',
rather than at zero. NDISASM, which assumes by default that any file you
give it is loaded at zero, will therefore need to be informed of this.

   The `-o' option allows you to declare a different origin for the file
you are disassembling. Its argument may be expressed in any of the NASM
numeric formats: decimal by default, if it begins with ``$'' or ``0x''
or ends in ``H'' it's `hex', if it ends in ``Q'' it's `octal', and if
it ends in ``B'' it's `binary'.

   Hence, to disassemble a `.COM' file:

            ndisasm -o100h filename.com

   will do the trick.


File: nasm.info,  Node: Section A.3.2,  Next: Section A.3.3,  Prev: Section A.3.1,  Up: Section A.3

A.3.2. Code Following Data: Synchronisation
-------------------------------------------

Suppose you are disassembling a file which contains some data which
isn't machine code, and _then_ contains some machine code. NDISASM will
faithfully plough through the data section, producing machine
instructions wherever it can (although most of them will look bizarre,
and some may have unusual prefixes, e.g. ``FS OR AX,0x240A''), and
generating `DB' instructions ever so often if it's totally stumped.
Then it will reach the code section.

   Supposing NDISASM has just finished generating a strange machine
instruction from part of the data section, and its file position is now
one byte _before_ the beginning of the code section. It's entirely
possible that another spurious instruction will get generated, starting
with the final byte of the data section, and then the correct first
instruction in the code section will not be seen because the starting
point skipped over it. This isn't really ideal.

   To avoid this, you can specify a ``synchronisation'' point, or indeed
as many synchronisation points as you like (although NDISASM can only
handle 2147483647 sync points internally). The definition of a sync
point is this: NDISASM guarantees to hit sync points exactly during
disassembly.  If it is thinking about generating an instruction which
would cause it to jump over a sync point, it will discard that
instruction and output a ``db'' instead. So it _will_ start disassembly
exactly from the sync point, and so you _will_ see all the instructions
in your code section.

   Sync points are specified using the `-s' option: they are measured in
terms of the program origin, not the file position. So if you want to
synchronize after 32 bytes of a `.COM' file, you would have to do

            ndisasm -o100h -s120h file.com

   rather than

            ndisasm -o100h -s20h file.com

   As stated above, you can specify multiple sync markers if you need
to, just by repeating the `-s' option.


File: nasm.info,  Node: Section A.3.3,  Next: Section A.3.4,  Prev: Section A.3.2,  Up: Section A.3

A.3.3. Mixed Code and Data: Automatic (Intelligent) Synchronisation
-------------------------------------------------------------------

Suppose you are disassembling the boot sector of a `DOS' floppy (maybe
it has a virus, and you need to understand the virus so that you know
what kinds of damage it might have done you). Typically, this will
contain a `JMP' instruction, then some data, then the rest of the code.
So there is a very good chance of NDISASM being _misaligned_ when the
data ends and the code begins. Hence a sync point is needed.

   On the other hand, why should you have to specify the sync point
manually?  What you'd do in order to find where the sync point would
be, surely, would be to read the `JMP' instruction, and then to use its
target address as a sync point. So can NDISASM do that for you?

   The answer, of course, is yes: using either of the synonymous
switches `-a' (for automatic sync) or `-i' (for intelligent sync) will
enable `auto-sync' mode. Auto-sync mode automatically generates a sync
point for any forward-referring PC-relative jump or call instruction
that NDISASM encounters. (Since NDISASM is one-pass, if it encounters a
PC- relative jump whose target has already been processed, there isn't
much it can do about it...)

   Only PC-relative jumps are processed, since an absolute jump is
either through a register (in which case NDISASM doesn't know what the
register contains) or involves a segment address (in which case the
target code isn't in the same segment that NDISASM is working in, and
so the sync point can't be placed anywhere useful).

   For some kinds of file, this mechanism will automatically put sync
points in all the right places, and save you from having to place any
sync points manually. However, it should be stressed that auto-sync
mode is _not_ guaranteed to catch all the sync points, and you may
still have to place some manually.

   Auto-sync mode doesn't prevent you from declaring manual sync
points: it just adds automatically generated ones to the ones you
provide. It's perfectly feasible to specify `-i' _and_ some `-s'
options.

   Another caveat with auto-sync mode is that if, by some unpleasant
fluke, something in your data section should disassemble to a
PC-relative call or jump instruction, NDISASM may obediently place a
sync point in a totally random place, for example in the middle of one
of the instructions in your code section. So you may end up with a
wrong disassembly even if you use auto-sync. Again, there isn't much I
can do about this. If you have problems, you'll have to use manual sync
points, or use the `-k' option (documented below) to suppress
disassembly of the data area.


File: nasm.info,  Node: Section A.3.4,  Next: Section A.4,  Prev: Section A.3.3,  Up: Section A.3

A.3.4. Other Options
--------------------

The `-e' option skips a header on the file, by ignoring the first N
bytes. This means that the header is _not_ counted towards the
disassembly offset: if you give `-e10 -o10', disassembly will start at
byte 10 in the file, and this will be given offset 10, not 20.

   The `-k' option is provided with two comma-separated numeric
arguments, the first of which is an assembly offset and the second is a
number of bytes to skip. This _will_ count the skipped bytes towards
the assembly offset: its use is to suppress disassembly of a data
section which wouldn't contain anything you wanted to see anyway.

The following sections show the instructions which NASM currently
supports.  For each instruction, there is a separate entry for each

     4.1.9::.

   * Fuzzy operand size logic introduced.

   * Fix COFF stack overrun on too long export identifiers.

   * Fix Macho-O alignment bug.

   * Fix crashes with -fwin32 on file with many exports.

     passed).

   * Append ending token for `.stabs' records in the ELF output format.

   * New NSIS script which uses ModernUI and MultiUser approach.

   * Visual Studio 2008 NASM integration (rules file).

   * Warn a user if a constant is too long (and as result will be
     stripped).

   * The obsoleted pre-XOP AMD SSE5 instruction set which was never
     actualized was removed.

   * Fix stack overrun on too long error file name passed from the
     command line.

   * Bind symbols to the .text section by default (ie in case if SECTION
     directive was omitted) in the ELF output format.

File: nasm.info,  Node: Section C.1.2,  Next: Section C.1.3,  Prev: Section C.1.1,  Up: Section C.1

C.1.2. Version 2.07
-------------------

   * NASM is now under the 2-clause BSD license. See *note Section
     1.1.2::.

   * Fix the section type for the `.strtab' section in the `elf64'
     output format.

   * Fix the handling of `COMMON' directives in the `obj' output format.

   * New `ith' and `srec' output formats; these are variants of the
     `bin' output format which output Intel hex and Motorola S-records,
     respectively. See *note Section 7.2:: and *note Section 7.3::.

   * `rdf2ihx' replaced with an enhanced `rdf2bin', which can output
     binary, COM, Intel hex or Motorola S-records.

   * The Windows installer now puts the NASM directory first in the
     `PATH' of the "NASM Shell".

   * Revert the early expansion behavior of `%+' to pre-2.06 behavior:
     `%+' is only expanded late.

   * Yet another Mach-O alignment fix.

   * Don't delete the list file on errors. Also, include error and
     warning information in the list file.

   * Support for 64-bit Mach-O output, see *note Section 7.8::.

   * Fix assert failure on certain operations that involve strings with
     high-bit bytes.


File: nasm.info,  Node: Section C.1.3,  Next: Section C.1.4,  Prev: Section C.1.2,  Up: Section C.1

C.1.3. Version 2.06
-------------------

   * This release is dedicated to the memory of Charles A. Crayne, long
     time NASM developer as well as moderator of `comp.lang.asm.x86'
     and author of the book _Serious Assembler_. We miss you, Chuck.

   * Support for indirect macro expansion (`%[...]'). See *note Section
     4.1.3::.

   * `%pop' can now take an argument, see *note Section 4.7.1::.

   * The argument to `%use' is no longer macro-expanded. Use `%[...]'
     if macro expansion is desired.

   * Support for thread-local storage in ELF32 and ELF64. See *note
     Section 7.9.4::.

   * Fix crash on `%ifmacro' without an argument.

   * Correct the arguments to the `POPCNT' instruction.

   * Fix section alignment in the Mach-O format.

   * Update AVX support to version 5 of the Intel specification.

   * Fix the handling of accesses to context-local macros from higher
     levels in the context stack.

   * Treat `WAIT' as a prefix rather than as an instruction, thereby
     allowing constructs like `O16 FSAVE' to work correctly.

   * Support for structures with a non-zero base offset. See *note
     Section 4.11.10::.

   * Correctly handle preprocessor token concatenation (see *note
     Section 4.3.8::) involving floating-point numbers.

   * The `PINSR' series of instructions have been corrected and
     rationalized.

   * Removed AMD SSE5, replaced with the new XOP/FMA4/CVT16 (rev 3.03)
     spec.

   * The ELF backends no longer automatically generate a `.comment'
     section.

   * Add additional "well-known" ELF sections with default attributes.
     See *note Section 7.9.2::.

File: nasm.info,  Node: Section C.1.5,  Next: Section C.1.6,  Prev: Section C.1.4,  Up: Section C.1

C.1.5. Version 2.05
-------------------

   * Fix redundant REX.W prefix on `JMP reg64'.

   * Make the behaviour of `-O0' match NASM 0.98 legacy behavior. See
     *note Section 2.1.22::.

   * `-w-user' can be used to suppress the output of `%warning'
     directives. See *note Section 2.1.24::.

     zero bytes.

   * Fix offsets in list files.

   * Fix `%include' inside multi-line macros or loops.

   * Fix error where NASM would generate a spurious warning on valid
     optimizations of immediate values.

File: nasm.info,  Node: Section C.1.6,  Next: Section C.1.7,  Prev: Section C.1.5,  Up: Section C.1

C.1.6. Version 2.04
-------------------

   * Sanitize macro handing in the `%error' directive.

   * New `%warning' directive to issue user-controlled warnings.

   * `%error' directives are now deferred to the final assembly phase.

   * New `%fatal' directive to immediately terminate assembly.

   * New `%strcat' directive to join quoted strings together.

   * New `%use' macro directive to support standard macro directives.
     See *note Section 4.6.4::.

   * Excess default parameters to `%macro' now issues a warning by
     default.  See *note Section 4.3::.

   * Fix `%ifn' and `%elifn'.

   * Fix nested `%else' clauses.

   * Correct the handling of nested `%rep's.

   * New `%unmacro' directive to undeclare a multi-line macro. See
     *note Section 4.3.11::.

   * Builtin macro `__PASS__' which expands to the current assembly
     pass.  See *note Section 4.11.9::.

   * `__utf16__' and `__utf32__' operators to generate UTF-16 and UTF-
     32 strings. See *note Section 3.4.5::.

   * Fix bug in case-insensitive matching when compiled on platforms
     that don't use the `configure' script. Of the official release
     binaries, that only affected the OS/2 binary.

   * Support for x87 packed BCD constants. See *note Section 3.4.7::.

   * Correct the `LTR' and `SLDT' instructions in 64-bit mode.

   * Fix unnecessary REX.W prefix on indirect jumps in 64-bit mode.

   * Add AVX versions of the AES instructions (`VAES'...).

   * Fix the 256-bit FMA instructions.

   * Add 256-bit AVX stores per the latest AVX spec.

   * VIA XCRYPT instructions can now be written either with or without
     `REP', apparently different versions of the VIA spec wrote them
     differently.

   * Add missing 64-bit `MOVNTI' instruction.

   * Fix the operand size of `VMREAD' and `VMWRITE'.

   * Numerous bug fixes, especially to the AES, AVX and VTX
     instructions.

   * The optimizer now always runs until it converges. It also runs
     even when disabled, but doesn't optimize. This allows most forward
     references to be resolved properly.

   * `%push' no longer needs a context identifier; omitting the context
     identifier results in an anonymous context.

     particular, `%idefine keyword $%?' can be used to make a keyword
     "disappear".

   * New options for dependency generation: `-MD', `-MF', `-MP', `-MT',
     `-MQ'.

   * New preprocessor directives `%pathsearch' and `%depend'; INCBIN
     reimplemented as a macro.

   * `%include' now resolves macros in a sane manner.

   * `%substr' can now be used to get other than one-character
     substrings.

   * New type of character/string constants, using backquotes (``...`'),
     which support C-style escape sequences.

C.2.3. Version 0.98.37
----------------------

   * Paths given in `-I' switch searched for `incbin'-ed as well as
     `%include'-ed files.

   * Added stabs debugging for the ELF output format, patch from Martin
     Wawro.

   * Fix `output/outbin.c' to allow origin > 80000000h.

   * Make `-U' switch work.

   * Fix the use of relative offsets with explicit prefixes, e.g.  `a32
     loop foo'.

   * Remove `backslash()'.

   * Fix the `SMSW' and `SLDT' instructions.

   * `-O2' and `-O3' are no longer aliases for `-O10' and `-O15'. If
     you mean the latter, please say so! :)

C.2.5. Version 0.98.35
----------------------

   * Fix build failure on 16-bit DOS (Makefile.bc3 workaround for
     compiler bug.)

   * Fix dependencies and compiler warnings.

   * Add "const" in a number of places.

   * Add -X option to specify error reporting format (use -Xvc to
     integrate with Microsoft Visual Studio.)

----------------------

   * Correct additional address-size vs. operand-size confusions.

   * Generate dependencies for all Makefiles automatically.

   * Add support for unimplemented (but theoretically available)
     registers such as tr0 and cr5. Segment registers 6 and 7 are
     called segr6 and segr7 for the operations which they can be
     represented.

     round out the version-query macros. version.pl now understands
     X.YYplWW or X.YY.ZZplWW as a version number, equivalent to
     X.YY.ZZ.WW (or X.YY.0.WW, as appropriate).

   * New keyword "strict" to disable the optimization of specific
     operands.

   * Fix the handing of size overrides with JMP instructions
     (instructions such as "jmp dword foo".)

   * More documentation updates.

   * Add -Ov option to get verbose information about optimizations.

   * Undo a braindead change which broke `%elif' directives.

   * Makefile updates.

C.2.33. 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

   * 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.

   * 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).

   * 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

     be re- written or removed, perhaps.

     well - testing might be desirable...

C.2.39. Version 0.98.03 with John Coffman's changes released 27-Jul-2000
------------------------------------------------------------------------

   * 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.

   * 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.

   * 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'.

   * 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)

   * 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)

C.2.40. 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

   * Kendall Bennett's SciTech MGL changes

   * Note that you must define "TASM_COMPAT" at compile-time to get the
     Tasm Ideal Mode compatibility.

   * 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.

   * standard.mac, macros.c: Added macros to ignore TASM directives
     before first include

   * nasm.h: Added extern declaration for tasm_compatible_mode

   * nasm.c: Added global variable tasm_compatible_mode

   * Added command line switch for TASM compatible mode (-t)

   * Changed version command line to reflect when compiled with TASM
     additions

   * Added response file processing to allow all arguments on a single
     line (response file is @resp rather than -@resp for NASM format).

   * labels.c: Changes islocal() macro to support TASM style @@local
     labels.

   * Added islocalchar() macro to support TASM style @@local labels.

   * parser.c: Added support for TASM style memory references (ie: mov
     [DWORD eax],10 rather than the NASM style mov DWORD [eax],10).

   * preproc.c: Added new directives, `%arg', `%local', `%stacksize' to
     directives table

   * Added support for TASM style directives without a leading % symbol.

   * Integrated a block of changes from Andrew Zabolotny
     <bit@eltech.ru>:

   * 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:

          %assign ofs     0

          %macro  arg     1
                  %xdefine %1 dword [esp+ofs]
                  %assign ofs ofs+4
          %endmacro

   * 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:

          %macro  abc     1
                  %define %1 hello
          %endm

          abc     %$here
          %$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.

   * Added a check for "cstk" in smacro_defined() before calling
     get_ctx() - this allows for things like:

          %ifdef %$abc
          %endif

   to work without warnings even in no context.

   * 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.

   * 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.

   * Added expansion of string that is output by `%error' directive. Now
     you can do things like:

          %define hello(x) Hello, x!

          %define %$name andy
          %error "hello(%$name)"

   Same happened with `%include' directive.

   * 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

          %define %$abc hello
          %define __%$abc goodbye
          __%$abc

   would produce "incorrect" output: last line will expand to

          hello goodbyehello

   Not quite what you expected, eh? :-) The answer is that preprocessor
treats the `%define' construct as if it would be

          %define __ %$abc goodbye

   (note the white space between __ and %$abc). After my "fix" it will
"correctly" expand into

          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'

   * 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).

   * 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:

            [WARNING macro-selfref]

            %macro          push    1-*
                    %rep    %0
                            push    %1
                            %rotate 1
                    %endrep
            %endmacro

                            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).

   * 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.

   * Added the %+ operator in single-line macros for concatenating two
     identifiers. Usage example:

            %define _myfunc _otherfunc
            %define cextern(x) _ %+ x
            cextern (myfunc)

   After first expansion, third line will become "_myfunc". After this
expansion is performed again so it becomes "_otherunc".

   * Now if preprocessor is in a non-emitting state, no warning or
     error will be emitted. Example:

            %if 1
                    mov     eax,ebx
            %else
                    put anything you want between these two brackets,
                    even macro-parameter references %1 or local
                    labels %$zz or macro-local labels %%zz - no
                    warning will be emitted.
            %endif

   * Context-local variables on expansion as a last resort are looked
     up in outer contexts. For example, the following piece:

            %push   outer
            %define %$a [esp]

                    %push   inner
                    %$a
                    %pop
            %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:

            %define %$arg1  [esp+4]
            test    eax,eax
            if      nz
                    mov     eax,%$arg1
            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.

   * Fixed memory leak in `%undef'. The origline wasn't freed before
     exiting on success.

   * Fixed trap in preprocessor when line expanded to empty set of
     tokens. This happens, for example, in the following case:

            #define SOMETHING
            SOMETHING

C.2.41. Version 0.98
--------------------

All changes since NASM 0.98p3 have been produced by H. Peter Anvin
<hpa@zytor.com>.

   * The documentation comment delimiter is

   * Allow EQU definitions to refer to external labels; reported by
     Pedro Gimeno.

   * Re-enable support for RDOFF v1; reported by Pedro Gimeno.

   * Updated License file per OK from Simon and Julian.


File: nasm.info,  Node: Section C.2.42,  Next: Section C.2.43,  Prev: Section C.2.41,  Up: Section C.2

C.2.42. Version 0.98p9
----------------------

   * Update documentation (although the instruction set reference will
     have to wait; I don't want to hold up the 0.98 release for it.)

   * 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.

   * Fix handling of implicit sizes in PSHUFW and PINSRW, reported by
     Stefan Hoffmeister.

   * Resurrect the -s option, which was removed when changing the
     diagnostic output to stdout.


File: nasm.info,  Node: Section C.2.43,  Next: Section C.2.44,  Prev: Section C.2.42,  Up: Section C.2

C.2.43. Version 0.98p8
----------------------

   * Fix for "DB" when NASM is running on a bigendian machine.

   * Invoke insns.pl once for each output script, making Makefile.in
     legal for "make -j".

   * Improve the Unix configure-based makefiles to make package
     creation easier.

   * Included an RPM .spec file for building RPM (RedHat Package
     Manager) packages on Linux or Unix systems.

   * Fix Makefile dependency problems.

   * Change src/rdsrc.pl to include sectioning information in info
     output; required for install-info to work.

   * Updated the RDOFF distribution to version 2 from Jules; minor
     massaging to make it compile in my environment.

   * Split doc files that can be built by anyone with a Perl
     interpreter off into a separate archive.

   * "Dress rehearsal" release!


File: nasm.info,  Node: Section C.2.44,  Next: Section C.2.45,  Prev: Section C.2.43,  Up: Section C.2

C.2.44. Version 0.98p7
----------------------

   * Fixed opcodes with a third byte-sized immediate argument to not
     complain if given "byte" on the immediate.

   * Allow `%undef' to remove single-line macros with arguments. This
     matches the behaviour of #undef in the C preprocessor.

   * 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.

   * Minor cleanups.

   * Went through the list of Katmai instructions and hopefully fixed
     the (rather few) mistakes in it.

   * (Hopefully) fixed a number of disassembler bugs related to
     ambiguous instructions (disambiguated by -p) and SSE instructions
     with REP.

   * Fix for bug reported by Mark Junger: "call dword 0x12345678"
     should work and may add an OSP (affected CALL, JMP, Jcc).

   * Fix for environments when "stderr" isn't a compile-time constant.


File: nasm.info,  Node: Section C.2.45,  Next: Section C.2.46,  Prev: Section C.2.44,  Up: Section C.2

C.2.45. Version 0.98p6
----------------------

   * 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.

   * 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.

   * Recognize "idt" or "centaur" for the -p option to ndisasm.

   * Changed error messages back to stderr where they belong, but add
     an -E option to redirect them elsewhere (the DOS shell cannot
     redirect stderr.)

   * -M option to generate Makefile dependencies (based on code from
     Alex Verstak.)

   * `%undef' preprocessor directive, and -u option, that undefines a
     single-line macro.

   * OS/2 Makefile (Mkfiles/Makefile.os2) for Borland under OS/2; from
     Chuck Crayne.

   * Various minor bugfixes (reported by): - Dangling `%s' in preproc.c
     (Martin Junker)

   * 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.

   * Updated the License file per agreement with Simon and Jules to
     include a GPL distribution clause.

C.2.46. Version 0.98p3.7
------------------------

   * (Hopefully) fixed the canned Makefiles to include the outrdf2 and
     zoutieee modules.

   * Renamed changes.asm to changed.asm.


File: nasm.info,  Node: Section C.2.47,  Next: Section C.2.48,  Prev: Section C.2.46,  Up: Section C.2

C.2.47. Version 0.98p3.6
------------------------

   * 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.


File: nasm.info,  Node: Section C.2.48,  Next: Section C.2.49,  Prev: Section C.2.47,  Up: Section C.2

C.2.48. Version 0.98p3.5
------------------------

   * 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.

   * 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.

   * 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.

   * Added AMD-only SYSCALL and SYSRET instructions.

   * Make SSE actually work, and add new Katmai MMX instructions.

   * Added a -p (preferred vendor) option to ndisasm so that it can
     distinguish e.g. Cyrix opcodes also used in SSE. For example:

          ndisasm -p cyrix aliased.bin
          00000000  670F514310        paddsiw mm0,[ebx+0x10]
          00000005  670F514320        paddsiw mm0,[ebx+0x20]
          ndisasm -p intel aliased.bin
          00000000  670F514310        sqrtps xmm0,[ebx+0x10]
          00000005  670F514320        sqrtps xmm0,[ebx+0x20]

   * Added a bunch of Cyrix-specific instructions.

C.2.49. Version 0.98p3.4
------------------------

   * 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.

   * DOS DJGPP+"Opus Make" Makefile from John S. Fine.

   * changes.asm changes from John S. Fine.


File: nasm.info,  Node: Section C.2.50,  Next: Section C.2.51,  Prev: Section C.2.49,  Up: Section C.2

C.2.50. Version 0.98p3.3
------------------------

   * Patch from Conan Brink to allow nesting of `%rep' directives.

   * 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.

   * Updated changes.asm to include the latest changes.

   * 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.

   * We would silently generate broken tools if insns.dat wasn't sorted
     properly. Change insns.pl so that the order doesn't matter.

   * 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".


File: nasm.info,  Node: Section C.2.51,  Next: Section C.2.52,  Prev: Section C.2.50,  Up: Section C.2

C.2.51. Version 0.98p3.2
------------------------

   * Merged in John S. Fine's changes from his 0.98-J4 prerelease; see
     http://www.csoft.net/cz/johnfine/

   * 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.

   * Removed BASIC programs from distribution. Get a Perl interpreter
     instead (see below.)

   * Calling this "pre-release 3.2" rather than "p3-hpa2" because of
     John's contributions.

   * 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".


File: nasm.info,  Node: Section C.2.52,  Next: Section C.2.53,  Prev: Section C.2.51,  Up: Section C.2

C.2.52. Version 0.98p3-hpa
--------------------------

   * Merged nasm098p3.zip with nasm-0.97.tar.gz to create a fully
     buildable version for Unix systems (Makefile.in updates, etc.)

   * 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.

   * 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.)

   * MAX_SYMBOL was defined to be 9, but LOADALL286 and LOADALL386 are
     10 characters long. Now MAX_SYMBOL is derived from insns.dat.

   * 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 http://www.cpan.org/ports/index.html.

C.2.53. Version 0.98 pre-release 3
----------------------------------

   * added response file support, improved command line handling, new
     layout help screen

   * fixed limit checking bug, 'OUT byte nn, reg' bug, and a couple of
     rdoff related bugs, updated Wishlist; 0.98 Prerelease 3.


File: nasm.info,  Node: Section C.2.54,  Next: Section C.2.55,  Prev: Section C.2.53,  Up: Section C.2

C.2.54. Version 0.98 pre-release 2
----------------------------------

   * 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


File: nasm.info,  Node: Section C.2.55,  Next: Section C.3,  Prev: Section C.2.54,  Up: Section C.2

C.2.55. Version 0.98 pre-release 1
----------------------------------

   * Fixed a bug whereby STRUC didn't work at all in RDF.

   * Fixed a problem with group specification in PUBDEFs in OBJ.

   * Improved ease of adding new output formats. Contribution due to
     Fox Cutter.

   * 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.

   * 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.

   * 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.

   * Fixed a stale-pointer bug in the handling of the NASM environment
     variable.  Thanks to Thomas McWilliams.

   * ELF had a hard limit on the number of sections which caused
     segfaults when transgressed. Fixed.

   * Added ability for ndisasm to read from stdin by using `-' as the
     filename.

   * ndisasm wasn't outputting the TO keyword. Fixed.

   * 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.

   * 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.

   * All messages now appear on stdout, as sending them to stderr
     serves no useful purpose other than to make redirection difficult.

   * Fixed the problem with EQUs pointing to an external symbol - this
     now generates an error message.

   * Allowed multiple size prefixes to an operand, of which only the
     first is taken into account.

   * 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.

   * Reformatted a lot of the source code to be more readable. Included
     'coding.txt' as a guideline for how to format code for
     contributors.

   * Stopped nested `%reps' causing a panic - they now cause a slightly
     more friendly error message instead.

   * Fixed floating point constant problems (patch by Pedro Gimeno)

   * Fixed the return value of insn_size() not being checked for -1,
     indicating an error.

   * Incorporated 3Dnow! instructions.

   * Fixed the 'mov eax, eax + ebx' bug.

   * Fixed the GLOBAL EQU bug in ELF. Released developers release 3.

   * Incorporated John Fine's command line parsing changes

   * Incorporated David Lindauer's OMF debug support

   * Made changes for LCC 4.0 support (`__NASM_CDecl__', removed
     register size specification warning when sizes agree).

C.3.1. Version 0.97 released December 1997
------------------------------------------

   * This was entirely a bug-fix release to 0.96, which seems to have
     got cursed. Silly me.

   * Fixed stupid mistake in OBJ which caused `MOV EAX,<constant>' to
     fail.  Caused by an error in the `MOV EAX,<segment>' support.

   * ndisasm hung at EOF when compiled with lcc on Linux because lcc on
     Linux somehow breaks feof(). ndisasm now does not rely on feof().

   * A heading in the documentation was missing due to a markup error
     in the indexing. Fixed.

   * 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,...'

   * 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.

   * Added internal.doc back in to the distribution archives - it was
     missing in 0.96 *blush*

   * Fixed bug causing 0.96 to be unable to assemble its own test files,
     specifically objtest.asm. *blush again*

   * Fixed seg-faults and bogus error messages caused by mismatching
     `%rep' and `%endrep' within multi-line macro definitions.

   * Fixed a problem with buffer overrun in OBJ, which was causing
     corruption at ends of long PUBDEF records.

   * Separated DOS archives into main-program and documentation to
     reduce download size.


File: nasm.info,  Node: Section C.3.2,  Next: Section C.3.3,  Prev: Section C.3.1,  Up: Section C.3

C.3.2. Version 0.96 released November 1997
------------------------------------------

   * 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.

   * 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.

   * 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.

   * 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.

   * 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'.

   * 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.

   * 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.

   * Fixed some buffer overrun problems with large OBJ output files.
     Thanks to DJ Delorie for the bug report and fix.

   * Made preprocess-only mode actually listen to the `%line' markers
     as it prints them, so that it can report errors more sanely.

   * Re-designed the evaluator to keep more sensible track of
     expressions involving forward references: can now cope with
     previously-nightmare situations such as:

       mov ax,foo | bar
       foo equ 1
       bar equ 2

   * Added the ALIGN and ALIGNB standard macros.

   * Added PIC support in ELF: use of WRT to obtain the four extra
     relocation types needed.

   * Added the ability for output file formats to define their own
     extensions to the GLOBAL, COMMON and EXTERN directives.

   * Implemented common-variable alignment, and global-symbol type and
     size declarations, in ELF.

   * Implemented NEAR and FAR keywords for common variables, plus
     far-common element size specification, in OBJ.

   * Added a feature whereby EXTERNs and COMMONs in OBJ can be given a
     default WRT specification (either a segment or a group).

   * Transformed the Unix NASM archive into an auto-configuring package.

   * 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.

   * 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.

   * Added the ability to specify sections' alignment requirements in
     Win32 object files and pure binary files.

   * 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 ||.

   * Added a preprocessor repeat construct: `%rep' / `%exitrep' /
     `%endrep'.

   * Added the __FILE__ and __LINE__ standard macros.

   * Added a sanity check for number constants being greater than
     0xFFFFFFFF.  The warning can be disabled.

   * Added the %0 token whereby a variadic multi-line macro can tell
     how many parameters it's been given in a specific invocation.

   * Added `%rotate', allowing multi-line macro parameters to be cycled.

   * Added the `*' option for the maximum parameter count on multi-line
     macros, allowing them to take arbitrarily many parameters.

   * Added the ability for the user-level forms of EXTERN, GLOBAL and
     COMMON to take more than one argument.

   * Added the IMPORT and EXPORT directives in OBJ format, to deal with
     Windows DLLs.

   * Added some more preprocessor `%if' constructs: `%ifidn' /
     `%ifidni' (exact textual identity), and `%ifid' / `%ifnum' /
     `%ifstr' (token type testing).

   * 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).

   * Added NetBSD/FreeBSD/OpenBSD's variant of a.out format, complete
     with PIC shared library features.

   * 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.

   * 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.

   * Added the ability for a variable to be declared as EXTERN multiple
     times, and the subsequent definitions are just ignored.

   * We now allow instruction prefixes (CS, DS, LOCK, REPZ etc) to be
     alone on a line (without a following instruction).

   * Improved sanity checks on whether the arguments to EXTERN, GLOBAL
     and COMMON are valid identifiers.

   * 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.

   * ndisasm forgot to check whether the input file had been
     successfully opened. Now it does. Doh!

   * Added the Cyrix extensions to the MMX instruction set.

   * 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.

   * Added support for the PharLap OMF extension for 4096-byte segment
     alignment.
