This work is being done under contract with a company that has requested
to remain unnamed at the present time.
* bc-int.h (yasm_effaddr): Add strong flag to indicate if the effective
address is definitely an effective address; GAS does not use [] to designate
effective addresses so it's otherwise impossible to tell the difference
between "expr(,1)" and just "expr" (important for the relative jump
instructions).
* bytecode.h (yasm_ea_set_strong): New function to set the strong flag.
* bytecode.c (yasm_ea_set_strong): Implementation.
* x86bc.c (yasm_x86__ea_create_reg): Initialize strong flag.
* arch.h (yasm_insn_operand): Add deref flag to indicate use of "*foo" in
GAS syntax.
* arch.c (yasm_operand_create_reg, yasm_operand_create_segreg)
(yasm_operand_create_mem, yasm_operand_create_imm): Set deref flag to 0.
* gas: GAS syntax lexer and parser. Not all directives are implemented yet
(some will require additional core bytecodes).
* elf-objfmt.c (elf_objfmt_section_switch): Add support for GAS-style
section flags.
* x86arch.h (yasm_arch_x86): Add parser setting.
* x86arch.c (x86_create): Check for gas parser and initialize setting.
* x86bc.c (yasm_x86__ea_create_expr): Transform val+RIP to val wrt RIP when
using the GAS parser (this is how GAS interprets "expr(%rip)").
* x86id.re: Too many changes to enumerate in detail. Add new modifiers for
GAS suffixes. Start using them in a couple instructions. Split check_id
into subfunctions (still one entry point at present).
(yasm_x86__finalize_insn): Support new modifiers, reverse operands, derefs.
* yasm.c (main): Change all undef to extern when using GAS parser (this is
default GAS behavior).

represent a register group (e.g. indexed registers).
(yasm_arch_reggroup_get_reg): New function to get a specific register from
a register group and index.
(yasm_arch_module): Add module version of yasm_arch_reggroup_get_reg().
* lc3barch.c (lc3b_reggroup_get_reg): Implement.
(yasm_lc3b_LTX_arch): Point to implementation.
* x86arch.c (x86_reggroup_get_reg, yasm_x86_LTX_arch): Likewise.

undefined symbols extern if unused rather than causing undef errors.
* symrec.c (yasm_symtab_parser_finalize): Implement.
(symtab_finalize_info): New (more data to pass to
(symtab_parser_finalize_checksym): Update finalize helper.
* yasm.c (main): Update call to yasm_symtab_parser_finalize().
svn path=/trunk/yasm/; revision=1232
(yasm_arch_create): Add parser and error parameters; now the arch is given
the keyword of the parser in use. The error parameter allows the caller to
find out whether it was the machine name or the parser name that was in
error.
(yasm_arch_module): Change create definition to match yasm_arch_create().
(yasm_arch_create_error): New error typedef for yasm_arch_create() errors.
* lc3barch.c (lc3b_create): Update to match new yasm_arch_create().
* x86arch.c (x86_create): Likewise.
* yasm.c (main): Use new yasm_arch_create() and handle the two kinds of
errors it can now generate. Move parser creation up in the sequence so it
happens before the arch is created.

sections. This breaks section numbering between the file section headers
and the section numbering used by symbols to reference sections.
While we're here, don't even try to number sections during parse... this
numbering is getting overwritten anyway.
Fixes#59 (reported by hkmaly@gmail.com).

Yasm in the long run should generate this info itself via the use of objfmt

The NASM preprocessor implementation of this is ugly; the preprocessor
really needs a rewrite to clean it up, but there's other higher-priority
items on the TODO list.
svn path=/trunk/yasm/; revision=1211
Initial patch: Stephen Polkowski <stephen@centtech.com>
Added test case and tightened up so that vmread/vmwrite to/from 32-bit reg
is illegal in 64-bit mode.

nasm-macros.c is built. Now they build genmacro and generate nasm-macros.c
at build time, as it's no longer contained in the distribution.
svn path=/trunk/yasm/; revision=1205
* x86id.re (yasm_x86__parse_cpu): Add cases for "PRESCOTT", "SSE3", and "PNI".
(yasm_x86__parse_check_id): Add cases for all 13 new instructions.
Update FILD and FISTP so that common fildstp_insn can be used.
(lddqu_insn): New instruction format.
* x86arch.h (CPU_SSE3): New. Renumber others.
* sse3.asm, sse3.hex, sse3.errwarn: New test case for SSE3 instructions.
* x86/tests/Makefile.inc: Include test in build.

undocumented (in NASM) win32 object format "export" directive.
(yasm_win32_LTX_objfmt): Reference above instead of coff_objfmt_directive.
(coff_objfmt_section_switch): Add support for ".drectve" section.
(coff_objfmt_init_new_section): Refactored from coff_objfmt_section_switch.
* preproc.h (yasm_preproc_module): Add define_builtin for defining macros
before standard.mac macros are processed.
(yasm_preproc_builtin_define): Add prototype and macro to call above.
* raw-preproc.c (raw_preproc_define_builtin): Add (empty).
(yasm_raw_LTX_preproc): Use.
* nasm-preproc.c (nasm_preproc_define_builtin): Add wrapper around new
pp_builtin_define.
(yasm_nasm_LTX_preproc): Use.
* nasm-pp.h (pp_builtin_define): Add prototype.
* nasm-pp.c (builtindef): New list of builtin definitions.
(read_line): Iterate through builtindef.
(pp_builtin_define): Add to builtindef.
* standard.mac: Add wrapper around definition of ORG (only for bin objfmt),
add wrappered EXPORT definition.
* yasm.c (apply_preproc_builtins): Define __YASM_OBJFMT__ to selected objfmt.
(main): Call above in correct places.
* export.asm, export.hex, export.errwarn: New test for use of "export" macro
and directive.
svn path=/trunk/yasm/; revision=1199
* yasm-options.c (parse_cmdline): Make unrecognized options warnings instead
of errors.
These two changes make yasm more closely match the nasm command line. The
long-term fix for this will be making a nasm-like frontend.

expressions by outputting a 0 if the expr does not have an intnum equivalent.
This is not a fix: the real fix will need to be changing how listfmts get the
final data bytes for a bytecode. This "fix" only replaces the garbage with
0's, not the correct value (e.g. for relative jumps).
