2009-10-27glsl: fix memory leakBrian Paul
A slightly modified version of a patch from Vinson Lee.
2009-10-22ARB prog parser: Fix parameter array size comparisonIan Romanick
Array indexes are invalid when >= the maximum, but array sizes are only in valid when > the maximum. This prevented programs from declaring a single maximum size array. See the piglit vp-max-array test.
2009-10-15mesa: regenerated lex.yy.c w/ _mesa_strtod()Brian Paul
2009-10-15mesa: Use _mesa_strtod in the lexer for assembly shadersNeil Roberts
See bug 24531.

2009-10-01mesa: Return -FLT_MAX instead of 0 for LG2(0).Vinson Lee
lim x->0 log(x) = -inf so -FLT_MAX is a better approximation than 0 for LG2(0).
2009-09-29glsl: regenerated fileBrian Paul
2009-09-29glsl: rewrite sqrt(x) intrinsic to handle x=0Brian Paul
Since sqrt() is basically implemented in terms of RSQ/RCP we'll do a divide by zero if x=0 and wind up with unpredictable results. Now use CMP instruction to test for x<=0 and return zero in that case.
2009-09-29glsl: add support for CMP instructionBrian Paul
2009-09-25mesa: move declaration before codeVinson Lee
2009-09-24i965: Emit zero initialization for NV VP temporaries as required.Eric Anholt
This is similar to what r300 does inside the driver, but I've added it as a generic option since it seems most hardware will want it. Fixes piglit nv-init-zero-reg.vpfp and nv-init-zero-addr.vpfp.
2009-09-24mesa: Initialize NV_vertex_program fields for the parameter lists and such.Eric Anholt
This helps let drivers treat NV_vp like ARB_vp.
2009-09-24mesa: added commentBrian Paul

2009-09-23mesa: don't bias LOD in shader interpreter; do it in swrastBrian Paul
2009-09-21r300: Fix handling of NV_vertex_program parametersNicolai Hähnle
The handling is a bit inefficient, unfortunately, but I don't want to make any intrusive changes for Mesa 7.6. Signed-off-by: Nicolai Hähnle <nhaehnle@gmail.com>
2009-09-15Merge branch 'mesa_7_5_branch' into mesa_7_6_branchBrian Paul
2009-09-14glsl: added some link debug code (disabled)Brian Paul
2009-09-14glsl: remove extra #version directives from concatenated shader sourcesBrian Paul
When we concatenate shaders to do our form of poor-man linking, if there's multiple #version directives, preprocessing fails. This change disables the extra #version directives by changing the first two chars to //. This should help with some Wine issues such as bug 23946.
2009-09-04ARB prog: replace 'unsigned' with 'gl_state_index'Brian Paul
Fixes compilation warnings with MSVC.
2009-09-04ARB prog: rename POINT, SIZE to POINT_TOK, SIZE_TOKBrian Paul
Fixes symbol collisions with typedefs in Microsoft headers. Perhaps we should prefix/suffix all the lexer tokens to avoid this.
2009-09-01ARB prog parser: Fix handling of stateOptModMatNumIan Romanick
The optional array index should clearly be enclosed in square brackets. This helps the oglconform test vp_binding.c get a bit farther, but it still fails.

2009-08-26glsl: asst. clean-ups in set_program_uniform()Brian Paul
Remove redunant type check for samplers (assert instead). Move some local vars. Update comments.

2009-08-26glsl: fix bug in sampler array indexingBrian Paul
Need to add the 'offset' parameter when indexing the parameter array. Before, if we were setting arrays of samplers, we were actually only setting the 0th sampler's value. Because of how progs/glsl/samplers.c is constructed, this wasn't showing up as a failure in the samplers_array output.
2009-08-25glsl: update a texture/sampler commentBrian Paul
2009-08-25glsl: implement shader sampler validationBrian Paul
Shader validation should fail if there are two samplers of different types which reference the same texture unit. For example, if a cubemap sampler and a 2D sampler both reference texture unit 0, that's invalid.
2009-08-25mesa: print some program fields in binary tooBrian Paul
2009-08-24ARB prog: Set error instead of falling through with incorrect valueBrian Paul
If a fragment program only parameter was queried of a vertex program (e.g., GL_MAX_PROGRAM_TEX_INDIRECTIONS_ARB) no error would be set and a random value would be returned. This caused 'glxinfo -l' to show the same values for GL_MAX_PROGRAM_ALU_INSTRUCTIONS_ARB, GL_MAX_PROGRAM_TEX_INSTRUCTIONS_ARB, GL_MAX_PROGRAM_TEX_INDIRECTIONS_ARB, GL_MAX_PROGRAM_NATIVE_ALU_INSTRUCTIONS_ARB, GL_MAX_PROGRAM_NATIVE_TEX_INSTRUCTIONS_ARB, GL_MAX_PROGRAM_NATIVE_TEX_INDIRECTIONS_ARB as for GL_MAX_PROGRAM_ENV_PARAMETERS_ARB. This is confusing and incorrect. (cherry picked from master, commit 4bccd693a72a0b42dffc849034263a68e779ca91)
