2009-09-10NV fp parser: Add support for condition codesIan Romanick
Conditional write masks and the condition-code based KIL instruction are all supported. The specific behavior of KIL in the following shader may or may not match the behavior of other implementations: !!ARBfp1.0 TEMP GT; MOVC GT, fragment.texcoord[0]; KIL GT.x; END Should be it interpreted as 'KIL srcReg' or as 'KIL ccTest'? The current parser will interpret it as 'KIL srcReg'.
2009-09-04NV fp parser: Support instruction and TEMP / OUTPUT sizesIan Romanick
Adds support for declaring TEMP and OUTPUT variables as 'LONG' or 'SHORT' precision. The precision specifiers are parsed, but they are currently ignored. Some support for this may be added in the future, but neither Intel hardware nor, as far as I'm aware, Radeon hardware support multiple precisions. Also adds support for instruction precision ('X', 'H', and 'R') suffixes and instruction condition code output ('C') suffix. This results in a fairly major change to the lexer. Instructions are matched with all the possible suffix strings. The suffix string are then carved off by a context (i.e., which program mode and options are set) aware parser that converts the suffixes to bits in prog_instruction. This could have been handled in the same way _SAT was originally handled in the lexer, but it would have resulted in a very large lexer with lots of opportunity for cut-and-paste errors.

2009-07-27ARB prog parser: Add support for GL_MESA_texture_arrayIan Romanick
This isn't really tested yet as no drivers actually support this extension.
2009-07-27ARB prog parser: Correct handling of some extensions that interact w/ARB_vpIan Romanick
2009-07-20ARB_fp/vp: Initial import of new ARB vp/fp assemblerIan Romanick
This still needs quite a bit of work, but a bunch of the programs in progs/vp produce correct results.
