2008-12-30mesa: fix bug in evaluation of structure fieldsBrian Paul
Fixes incorrect size information. See bug 19273.
2008-12-30mesa: allow variable indexing into the predefined uniform variable arraysBrian Paul
This allows code such as "vec4 a = gl_LightSource[i].ambient;" to work. When a built-in uniform array is indexed with a variable index we need to "unroll" the whole array into the parameter list (aka constant buffer) because we don't know which elements may be accessed at compile-time. In the case of the gl_LightSource array of size [8], we emit 64 state references into the parameter array (8 elements times 8 vec4s per gl_LightSourceParameters struct). Previously, we only allowed constant-indexed references to uniform arrays (such as gl_LightSource[2].position) which resulted in a single state reference being added to the parameter array, not 64. We still optimize this case. Users should be aware that using "gl_LightSource[i].ambient" in their shaders is a bit expensive since state validation will involve updating all 64 light source entries in the parameter list.

2008-12-19GLSL: The LOG2 macro doesn't have enough precisionIan Romanick
It looks like the LOG2 macro only has 8 or 9 bits of precission, but the ARB_vertex_program spec says "accurate to at least 10 bits".

2008-12-16mesa: disable debug outputBrian Paul
2008-12-16mesa: fix some GLSL array regressionsBrian Paul
array.length() wasn't working. Swizzle mask for accessing elements of float arrays was incorrect.
2008-12-15mesa: rename slang_library_noise.[ch] to prog_noise.[ch] and rename functionsBrian Paul
The noise functions were not glsl-specific. Also, ran indent on the code to clean it up.
2008-12-15mesa: bump glsl grammar revisionBrian Paul
And update some copyrights.
2008-12-15mesa: more re-org of variable declarations in glsl compilerBrian Paul
2008-12-15mesa: more comments, clean upBrian Paul
2008-12-15mesa: added comments, remove unused codeBrian Paul
2008-12-15mesa: checkpoint: handle uniform vars in _slang_gen_var_decl()Brian Paul
This allows uniform declarations with scalar/array initializers. The code is rough though, and will be cleaned up.
2008-12-12mesa: use IFLOOR(x) instead of (int) FLOORF(x)Brian Paul
2008-12-12mesa: place glsl constant arrays in constant memoryBrian Paul
For example, a declaration like const float[3] xxx = float[3](1.1, 2.2, 3.3); will place the array in the constant buffer whereas a regular, non-const array would be placed in the temporary register file. Next up: do the same thing for uniform arrays.

2008-12-12mesa: basic array constructors work nowBrian Paul
For example: float[3] xxx = float[3](1.1, 2.2, 3.3); Optimizations for const-qualified arrays next.

Function that return arrays should work now.

2008-12-11mesa: checkpoint commit of GLSL 1.20 array syntax.Brian Paul
This allows things like float[3] x = float[3](1., 2., 3.); Parsing and AST construction now. Codegen not working yet.
