01/28/01 - fbk - 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"
01/28/01 - fbk - cosmetic modifications to nasm.c, nasm.h,
AUTHORS, MODIFIED
01/18/01 - fbk - "metalbrain"s jecxz bug fix in insns.dat
- alter nasmdoc.src to match - version "0.98.06f"
01/09/01 - fbk - removed the "outforms.h" file - it appears to be
someone's old backup of "outform.h". version "0.98.06e"
01/09/01 - 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...
---- Nelson Rush resigns from the group. Big thanks to Nelson for
his leadership and enthusiasm in getting these changes
incorporated into Nasm!
---- fbk - [list +], [list -] directives - ineptly implemented, should
be re-written or removed, perhaps.
---- Brian Raiter / fbk - "elfso bug" fix - applied to aoutb format
as well - testing might be desirable...
08/07/00 - James Seter - -postfix, -prefix command line switches.
---- Yuri Zaporogets - rdoff utility changes.
John Coffman's changes:
For the JMP and other optimizations see the file README03.txt.
Kendall Bennett's changes:
For changes since the 0.98 release see the file scitech.txt. Note
that you must define "TASM_COMPAT" at compile-time
to get the Tasm Ideal Mode compatibility.

This is a specially patched version of NASM. It can be used to supplement
building of Crystal Space, the Open Source 3D Engine project. You can find
Crystal Space at the following locations:
http://crystal.linuxgames.com/
http://crystal.sourceforge.net/
Details of changes in this version of NASM follow.
-*- 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 to "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 %$abc
%endif
to work without warnings even in no context.
-*- Added a check for "cstk" in %if*ctx and %elif*ctx directives -
this allows to use %ifctx without excessive warnings. If there is
no active context, %ifctx goes through "false" branch.
-*- Removed "user error: " prefix with %error directive: it just clobbers the
output and has absolutely no functionality. Besides, this allows to write
macros that does not differ from build-in functions in any way.
-*- Added expansion of string that is output by %error directive. Now you
can do things like:
%define hello(x) Hello, x!
%define %$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-emmitting state, no warning or error
will be emmitted. Example:
%if 1
mov eax,ebx
%else
put anything you want between these two brackets,
even macro-parameter references %1 or local labels %$zz
or macro-local labels %%zz - no warning will be emmitted.
%endif
-*- Context-local variables on expansion as a last resort are looked up
in outer contexts. For example, the following piece:
%push outer
%define %$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.
-------------------------------// fixes for 0.98 //-----------------------------
-*- Fixed memory leak in %undef. The origline wasn't freed before
exiting on success.
-----------------------------// Fixes for 0.98.01 //----------------------------
-*- Fixed trap in preprocessor when line expanded to empty set of tokens.
This happens, for example, in the following case:
#define SOMETHING
SOMETHING

This directory contains the necessary files to port the C compiler
``LCC'' (available by FTP from sunsite.doc.ic.ac.uk in the directory
/computing/programming/languages/c/lcc) to compile for Linux (a.out or
ELF) or other supported operating systems by using NASM as a back-end
code generator.
This patch has been tested on lcc version 4.0.
NetWide Assembler for the SciTech MGL
-------------------------------------
To install:
This is a modified distribution of NASM, the Netwide Assembler. NASM
is a prototype general-purpose x86 assembler. It will currently output
flat-form binary files, a.out, COFF and ELF Unix object files,
Microsoft Win32 and 16-bit DOS object files, OS/2 object files, the
as86 object format, and a home-grown format called RDF.
- Copy `x86nasm.md' into the `src' directory of the lcc tree.
This version of NASM has been modified by SciTech Software such that it
can be used to assemble source code in the SciTech MGL graphics library,
and understands enough of TASM assembler syntax such that both NASM
and TASM can be used to generate assembler modules for the MGL graphics
library. A complete macro package is provided as part of the SciTech
MGL that provides macros to help in building modules that will work with
either assembler.
- Copy either `lin-elf.c' or `lin-aout.c' into the `etc' directory.
A pre-compiled binary of NASM is provided as part of the SciTech MGL
graphics library, however you may re-build the assembler from the sources
provided. To do so make sure you have the SciTech Makefile Utilties
correctly configured for your compiler, and then simly type:
- With previous versions, you had to modify x86-nasm.md if you weren't
using ELF. There is now inbuilt support within NASM in the shape
of the __CDECL__ macro, so this modification is no longer necessary.
unset DBG
dmake OPT=1
- Make the following changes to `bind.c' in the `src' directory:
to build an optimised, non-debug version of the assembler. If you wish
to rebuild for a different OS other than DOS or Win32, you will need to
first compile the DMAKE make program for your OS. See the DMAKE source
code for more information.
- Near the top of the file, add a line that reads
extern Interface x86nasmIR;
Licensing issues:
-----------------
- In the `bindings' array, add the lines
"x86-nasm", &x86nasmIR,
"x86/nasm", &x86nasmIR,
(in sensible looking places...)
For information about how you can distribute and use NASM, see the
file Licence.
A sample `bind.c' has been provided to show what the result of
this might look like. You might be able to get away with using it
directly...
The NASM web page is at http://www.cryogen.com/Nasm/
- Modify the lcc makefile to include rules for x86nasm.o: this will
have to be done in about three places. Just copy any line with
`x86' on it and modify it to read `x86nasm' everywhere. (Except
that in the list of object files that rcc is made up from, do
remember to ensure that every line but the last has a trailing
backslash...)
Bug reports specific to the SciTech MGL should be posted to SciTech
Software MGL newsgroups:
- You may have to modify the contents of `lin-elf.c' or `lin-aout.c'
to reflect the true locations of files such as crt0.o, crt1.o,
ld-linux.so and so forth. If you don't know where to find these,
compile a short C program with `gcc -v' and see what command line
gcc feeds to `ld'.
news://news.scitechsoft.com/scitech.mgl.developer
- You should now be able to build lcc, using `lin-elf.c' or
`lin-aout.c' as the system-dependent part of the `lcc' wrapper
program.
Bug reports (and patches if you can) for NASM itself that are not SciTech
MGL related should be sent to the authors at:
- Symlink x86nasm.c into the `src' directory before attempting the
triple test, or the compile will fail.
- Now it should pass the triple test, on either ELF or a.out. Voila!

; Summary:
; Misc macros to deal with PIC shared libraries
; Comment:
; Note that we have a different syntax for working with and without
; PIC shared libraries. In a PIC environment we should load first
; the address of the variable into a register and then work through
; that address, i.e: mov eax,myvar; mov [eax],1
; In a non-PIC environment we should directly write: mov myvar,1
; Example:
; extvar myvar
; GetGOT
; %ifdef PIC
; mov ebx,myvar ; get offset of myvar into ebx
; %else
; lea ebx,myvar

; Summary:
; Begin a procedure definition
; For performance reasons we don't use stack frame pointer EBP,
; instead we're using the [esp+xx] addressing. Because of this
; you should be careful when you work with stack pointer.
; The push/pop instructions are macros that are defined to
; deal correctly with these issues.
; Arguments:
; First argument - the procedure name
; Second optional argument - the number of bytes for local variables
; The following arguments could specify the registers that should be
; pushed at beginning of procedure and popped before exiting
; Example:
; proc MyTestProc
; proc MyTestProc,4,ebx,esi,edi

; total size of local arguments
%assign %$proc.locsize (%2+3) & 0xFFFC
; offset from esp to argument
%assign %$proc.argofs 4+%$proc.locsize
; additional offset to args (tracks push/pops)
%assign .$proc.stkofs 0
; offset from esp to local arguments
%assign %$proc.locofs 0
; Now push the registers that we should save

; Summary:
; Declare an argument passed on stack
; This macro defines two additional macros:
; first (with the name given by first argument) - [esp+xx]
; second (with a underscore appended to first argument) - esp+xx
; Arguments:
; First argument defines the procedure argument name
; Second optional parameter defines the size of the argument
; Default value is 4 (a double word)
; Example:
; arg .my_float
; arg .my_double,8

The Netwide Assembler: NASM
===========================
--------------------------------------------------------------------------------
SciTech MGL Modifications
--------------------------------------------------------------------------------
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-emmitting state, no warning or error
will be emmitted. Example:
%if 1
mov eax,ebx
%else
put anything you want between these two brackets,
even macro-parameter references %1 or local labels %$zz
or macro-local labels %%zz - no warning will be emmitted.
%endif
-*- Context-local variables on expansion as a last resort are looked up
in outer contexts. For example, the following piece:
%push outer
%define %$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
