VIM-GAS

This vim bundle adds advanced syntax highlighting for GNU as (AT&T).

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, ARM (thumb) and AVR instruction sets are included.
Opcodes supporting a size suffix are recognized plain as well as suffixed with b/w/l/q.

What does it look like?

Supported instructions a per version 0.16:

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> 

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, x64, x642, x86_64 

recognized extension groups:

       base, 3dnow, mmx, mmx2, sse, sse2, sse3, ssse3, sse4.1, sse4.2, sse4a, 
       sse5, avx, fma, vmx 

I hope this syntax file will be useful to other people - but don't blame me if it doesn't suit your needs.

CPP preprocessor macros

GAS allows code to be processed by the same preprocessor used for C/C++ code. So directives like #include, #define etc. will be highlighted using the C syntax highlighter if available.

This behavior can be turned off by setting the gasDisablePreproc option either globally in your .vimrc or on a per-buffer basis:

" globally disable preprocessor macro detection
:let g:gasDisablePreproc=1 


" disable only for this buffer 
let gasDisablePreproc=1 

Installation

This syntax file can either be installed manually, by using pathogen or vundle.

Manual Installation

Download gas.vim and copy the file to .vim/syntax/ in your home folder. Add this line to the end of your file:

/* vim: ft=gas : 
*/
