2009-10-27ARB prog parser: Fix epic memory leak in lexer / parser interfaceIan Romanick
Anything that matched IDENTIFIER was strdup'ed and returned to the parser. However, almost every case of IDENTIFIER in the parser just dropped the returned string on the floor. Every swizzle string, every option string, every use of a variable, etc. leaked memory. Create a temporary buffer in the parser state (string_dumpster and dumpster_size). Return strings from the lexer to the parser in the buffer. Grow the buffer as needed. When the parser needs to keep a string (i.e., delcaring a new variable), let it make a copy then. The only leak that valgrind now detects is /occasionally/ the copy of the program string in gl_program::String is leaked. I'm not seeing how. :(
2009-10-27ARB prog parser: Don't leak program stringIan Romanick
The program string is kept in the program object. On the second call into glProgramStringARB the previous kept string would be leaked.

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.

2009-10-01mesa: 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: 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.

2009-09-24i965: 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.

2009-09-21r300: Fix handling of NV_vertex_program parametersNicolai Hähnle

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: 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.

2009-08-24ARB 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)
