Peter Johnson	46c26f12a7	Fix incorrect invalidation of [eax+ebx+ecx-eax] and others like it. svn path=/trunk/yasm/; revision=725	22 years ago
Peter Johnson	b3e9ae6254	Don't fully simplify effective addresses before trying to determine their registers. svn path=/trunk/yasm/; revision=724	22 years ago
Peter Johnson	6591a155d0	Check for circular equ references (Bug#8). svn path=/trunk/yasm/; revision=723	22 years ago
Peter Johnson	3420509d65	x86_bc_resolve_jmprel(): Delete unused variable 'target'. svn path=/trunk/yasm/; revision=721	22 years ago
Peter Johnson	a3a9fd2aa0	Completely revamp how label resolution is done (part of Bug#6). Now calculates /distances/ between bytecodes in a section using bc_calc_dist() functions (a "typical" one is provided for most occasions). expr_expand_labelequ() is gone, as its functionality is integrated into expr_simplify(). Currently these changes break most bin objfmt output, as it doesn't know how to resolve absolute labels yet. Also, very preliminary expr support for :, SEG, and WRT operators has been added (part of Bug#2). Several other minor bug fixes. svn path=/trunk/yasm/; revision=718	22 years ago
Peter Johnson	f5f92a9d52	PSHUFW has 3 operands, not 2 (typo in num_operands value). svn path=/trunk/yasm/; revision=716	22 years ago
Peter Johnson	99818a7010	RET and RETN are exactly equivalent (the previous commit was wrong, but not for the reason stated; it just had the wrong base opcode). svn path=/trunk/yasm/; revision=715	22 years ago
Peter Johnson	e1107f96a2	Revert previous commit until we can do this the right way (C2 iw is an invalid opcode, it needs to be C2 or C3 iw). svn path=/trunk/yasm/; revision=714	22 years ago
Peter Johnson	302c7215b5	RET is a form of RETNF. svn path=/trunk/yasm/; revision=713	22 years ago
Peter Johnson	c1b04966ef	Fix lexing bug for XMM[0-7] (wrong character used to get register index). svn path=/trunk/yasm/; revision=712	22 years ago
Peter Johnson	ddb25b6aa7	Declare shifted constants unsigned longs (with UL) before shifting, to increase portability. svn path=/trunk/yasm/; revision=711	22 years ago
Peter Johnson	090a25b8d4	Rename intnum_new_int to intnum_new_uint, and add new signed version of intnum_new_int. Currently only just calls intnum_new_uint with a cast, but eventually there may be a better way of handling signed numbers. svn path=/trunk/yasm/; revision=708	22 years ago
Peter Johnson	c5ef1bf2dc	Eliminate duplicate code for callbacks from expr_expand_labelequ() by moving code and adding a resolve_precall function parameter (which caused cascading changes in bytecode-related sources). svn path=/trunk/yasm/; revision=701	22 years ago
Peter Johnson	97ad3394e2	The short forms (0x50+reg) of push/pop reg should be selected before the long (0xFF, ModRM) forms. svn path=/trunk/yasm/; revision=697	22 years ago
Peter Johnson	320a83294e	Finish remaining instructions (SSE, SSE2, Cyrix MMX). Changed CPU flags for MMX/SSE2 to reflect that it's the MMX or SSE2 cpu feature, not the cpu family. svn path=/trunk/yasm/; revision=694	22 years ago
Peter Johnson	9390dd2bbb	Add MMX/SSE2 instructions. svn path=/trunk/yasm/; revision=693	22 years ago
Peter Johnson	a2a986add9	Add segreg moves. svn path=/trunk/yasm/; revision=692	22 years ago
Peter Johnson	efafc7c6fb	Fix some bugs. - Typos in imul reg, imm (# of operands) - Fixes to push/pop. word/dword override opersize now. svn path=/trunk/yasm/; revision=691	22 years ago
Peter Johnson	ca721cf125	Implement relative jumps and calls. svn path=/trunk/yasm/; revision=689	22 years ago
Peter Johnson	8495e174cc	x86_parse_targetmod enum should start with value 1, not 0. svn path=/trunk/yasm/; revision=687	22 years ago
Peter Johnson	c2e982f901	Take opersize as an input for x86_bc_new_jmprel(). svn path=/trunk/yasm/; revision=686	22 years ago
Peter Johnson	2c090517fc	Flatten x86_targetval into x86_new_jmprel_data, as the former is no longer used in the parser. svn path=/trunk/yasm/; revision=685	22 years ago
Peter Johnson	cd573321b3	Finish all instructions except for relative jumps, mov segreg, MMX, SSE, and SSE2. svn path=/trunk/yasm/; revision=684	22 years ago
Peter Johnson	eb067621cf	Added rest of floating point instructions. Needed to add new action to add to opcode byte 1. svn path=/trunk/yasm/; revision=683	22 years ago
Peter Johnson	b630a6768b	Add checking of target modifier. Change operand typing mask constants to be more uniform. Increase operand type size to long from int, as it now can go over 16 bits. svn path=/trunk/yasm/; revision=682	22 years ago
Peter Johnson	70442d8b7f	Make "TO" a x86 targetmod. svn path=/trunk/yasm/; revision=681	22 years ago
Peter Johnson	d6cee4db08	Add a few control transfer instructions, plus set byte on flag, bit manip, int, bound, and 286 protection control. svn path=/trunk/yasm/; revision=678	22 years ago
Peter Johnson	ef8f221f24	Added shift instructions, as well as new "postponed" actions for things such as shift ,1 operands and imm operands that have sign-extended imm8 forms that can't be decided at parse-time. The x86 bc format already had support for these. Also fixed a bug in the lfs family (incorrect inst len). svn path=/trunk/yasm/; revision=677	22 years ago
Peter Johnson	0af7326e75	Add lea, l?s, and arithmetic instructions. Arithmetic instructions needed two additional actions: signed immediate and spare+ea. svn path=/trunk/yasm/; revision=676	22 years ago
Peter Johnson	e1eae9bae5	Add xchg, in, out. in and out required operand type Dreg (DL/DX/EDX) to be added. svn path=/trunk/yasm/; revision=675	22 years ago
Peter Johnson	ce0d675524	Add push and pop. This required adding some new specific operand types, which required adding to the number of bits allocated for the operand type. svn path=/trunk/yasm/; revision=674	22 years ago
Peter Johnson	035fea119a	Add explicit $(top_builddir) when running re2c. svn path=/trunk/yasm/; revision=672	22 years ago
Peter Johnson	3320945f95	Massive restructuring of lexing and parsing (NASM-compatible parser). Bugzilla Bug#3. Not all instructions are parsed yet, so this is actually a minor feature regression from the user side, but this commit lays the framework for much easier additions of new assembler syntaxes and architectures. The re2c tool is now used to generate the lexers, as it's much more flexibly function-oriented than lex. - nasm-bison.y is a repocopy+modify of nasm/bison.y.in. - x86arch.h now includes all of x86-int.h svn path=/trunk/yasm/; revision=670	22 years ago
Peter Johnson	6727a189ab	fucom* are FPU instructions. svn path=/trunk/yasm/; revision=660	22 years ago
Peter Johnson	3af9a80722	This file is going away soon, but it's still good to fix errors: CLTS was passing too many values to the twobyte group. svn path=/trunk/yasm/; revision=657	22 years ago
Peter Johnson	ac2743de63	Prevent spurious "Circular reference detected" errors by refining the return value for bc_resolve() to enum-defined flags. svn path=/trunk/yasm/; revision=623	23 years ago
Peter Johnson	a76d8561f7	Fix a couple bugs found by Splint (and do some other Splint cleanups). svn path=/trunk/yasm/; revision=600	23 years ago
Peter Johnson	fe8c2a009f	Restructure bc_calc_len() family into bc_resolve() family. Many many many bugfixes to the bc_tobytes() family and other functions. Binary object output is now close to complete: just a few more bugs to kill! svn path=/trunk/yasm/; revision=528	23 years ago
Peter Johnson	53002496e4	Fix a number of bugs in x86_checkea_calc_displen(). svn path=/trunk/yasm/; revision=527	23 years ago
Peter Johnson	d85e7014a8	Binary object format output! Lots of structural changes needed, particularly with regards to resolve_label(). MAJOR FIXME: The tobytes() pass acts like a final optimization pass. This causes internal errors because of length mismatches (optimized to shorter len). svn path=/trunk/yasm/; revision=521	23 years ago
Peter Johnson	e56de0d158	Make call instruction work correctly. The old code generated a legal short form for it (opcode length 1, opcode 0, rather than opcode length 0). svn path=/trunk/yasm/; revision=520	23 years ago
Peter Johnson	4dd0912998	Fix bug in 32-bit displacement with no registers. svn path=/trunk/yasm/; revision=517	23 years ago
Peter Johnson	f61b5746f1	Don't compact into a short form if one's not available. svn path=/trunk/yasm/; revision=461	23 years ago
Peter Johnson	044cc90233	Make jcc's default to JR_SHORT in NASM syntax, and test for this possibility in calc_len(). svn path=/trunk/yasm/; revision=460	23 years ago
Peter Johnson	056b3fc52c	Finish bc_calc_len(), with fixes to x86_bc_calc_len_insn()'s EA sizing calcs, and implementation of x86_bc_calc_len_jmprel(). svn path=/trunk/yasm/; revision=459	23 years ago
Peter Johnson	5b2166d50a	Don't store "determined" immediate len and neg. Both will be determined from the expr when that's actually possible. svn path=/trunk/yasm/; revision=456	23 years ago
Peter Johnson	4949569151	Fix memory leak. Add assert call to silence LCLint. svn path=/trunk/yasm/; revision=454	23 years ago
Peter Johnson	ee74365f05	Add new bc_resolve() family, and rewrite calc_len to /just/ calculate the length, not modify anything else (particularly expressions w/temp. resolved labels). svn path=/trunk/yasm/; revision=452	23 years ago
Peter Johnson	cc635cc237	Change return type of calc_len() family back to int from unsigned long. svn path=/trunk/yasm/; revision=448	23 years ago
Peter Johnson	985d4e9b59	LCLint cleanups. svn path=/trunk/yasm/; revision=443	23 years ago
