syntax

description

This file defines a (almost) complete syntax for GNU as assembler. My motivation in writing this was the lack of a complete, working syntax for this common assembler. For now the basic as directives as well as the Intel / AMD instruction sets are included. Opcodes supporting a size suffix are recognised plain as well as suffixed with b/w/l/q. == NOTE ON UPDATES Please note that the whole project is now hosted on github - see https://github.com/HealsCodes/vim-gas/ I will try to keep the latest version available on vim.org however there is no 100% guarantee. Github offers the flexibility for everyone to easily participate and help me enhance this project. == Supported instructions a per version 0.6: -- X86 common instruction set (8086 - 686) -- Katmai Streaming SIMD instructions (SSE -- a.k.a. KNI, XMM, MMX2) -- Introduced in Deschutes but necessary for SSE support -- XSAVE group (AVX and extended state) -- Generic memory operations -- New MMX instructions introduced in Katmai -- AMD Enhanced 3DNow! (Athlon) instructions -- Willamette SSE2 Cacheability Instructions -- Willamette MMX instructions (SSE2 SIMD Integer Instructions) -- Willamette Streaming SIMD instructions (SSE2) -- Prescott New Instructions (SSE3) -- VMX Instructions -- Extended Page Tables VMX instructions -- Tejas New Instructions (SSSE3) -- AMD SSE4A -- New instructions in Barcelona -- Penryn New Instructions (SSE4.1) -- Nehalem New Instructions (SSE4.2) -- AMD SSE5 instructions -- Intel SMX -- Geode (Cyrix) 3DNow! additions -- Intel AES instructions -- Intel AVX AES instructions -- Intel AVX instructions -- Intel Carry-Less Multiplication instructions (CLMUL) -- Intel AVX Carry-Less Multiplication instructions (CLMUL) -- Intel Fused Multiply-Add instructions (FMA) -- VIA (Centaur) security instructions -- AMD XOP, FMA4 and CVT16 instructions (SSE5) -- Systematic names for the hinting nop instructions -- AVR -- ARM (thumb) You can set different highlighting for each set listed above by adding a line like this to you .vimrc: hi def link gasOpcodeX86_PENT_SSE  <some_highlighting> screenshot here: http://skitch.com/shirkrin/neq8c/gnu-as-syntax-for-vim == per-file opcode enable / disable Since version 0.6 it is possible to disable sets of opcodes by either CPU they where introduced in or by their extension name. This is done by setting a special variable recognized by gas.vim to the list of disabled opcodes. E.g. " globally disable all x86_64 opcodes :let g:gasDisableOpcodes='x86_64' " disable SSE and SSE2 for this buffer let b:gasDisableOpcodes='sse sse2' Disabled opcodes will be highlighted as errors. recognized CPU groups:            186, 286, 386, 3862, 486, 8086, amd, future, ia64, katmai, nehalem,             p6, pentium_m, pentium, prescott, sandybridge, hasswell, x64, x642, x86_64 recognized extension groups:            base, 3dnow, mmx, mmx2, sse, sse2, sse3, ssse3, sse4.1, sse4.2, sse4a,            sse5, avx, fma, vmx, avx, avx2 I hope this syntax file will be useful to other people   - but don't blame me if it doesn't suit your needs.

package	script version	date	Vim version	user	release notes
gas.vim	0.15	2021-11-30	7.0	René Köcher	Add various new intel instructions as well as support for AVR and ARM
gas.vim	0.9	2013-08-15	7.0	René Köcher	Add support for pop{,b,w,l,q} opcodes - credit goes to Hal Ashburner who provided the patch.
gas.vim	0.8	2009-12-29	6.0	René Köcher	Implemented some enhancements suggested by M. Herrmann: - add *inc* as keyword (not inc[bwlq]) - add '#' as comment character (without loosing C preprocessor support) - fix a few mnemonics which don't comply with b/w/l/q suffixes
gas.vim	0.7	2009-11-27	6.0	René Köcher	minor tweaks / fixes (popfl, stosl, typos in a few registers)
gas.vim	0.6	2009-11-26	6.0	René Köcher	Redone all opcodes - they where generated from a static opcode table and <b,w,l,q> suffixes are now recognized only for opcodes that really support them. New feature to disable opcodes (highlighted as Error) by either CPU or extension type. Set g:gasDisableOpcodes or b:gasDisableOpcodes to a space-separated list of CPU's or Extensions: E.g. leg b:gasDisableOpcodes='x86_64 sse sse2' CPUs:            186, 286, 386, 3862, 486, 8086, amd, future, ia64, katmai, nehalem,             p6, pentium_m, pentium, prescott, sandybridge, x64, x642, x86_64 Extensions:            base, 3dnow, mmx, mmx2, sse, sse2, sse3, ssse3, sse4.1, sse4.2, sse4a, sse5, avx, fma, vmx
gas.vim	0.5	2009-11-26	6.0	René Köcher	- improved syntax synchronizing - fixed strings with nested quotes - support for c-style pre-processor tags (via c.vim) Known Bugs: Pre-processor tokens require an extra blank line to not                        mix up the following assembler statement.
gas.vim	0.4	2009-11-21	6.0	René Köcher	Fixed an issue where braces and brackets would be shown as part of symbols.
