2008-07-03mesa: fix array storage allocation bugBrian Paul
2008-07-01mesa: fix a GLSL vector subscript/writemask bugBrian Paul
This fixes a failure for cases like: vec4 v; v[1] *= 2.0; The v[1] actually acts like a writemask, equivalent to v.y The fix is a bit convoluted, but will do for now.

2008-07-01mesa: better function inlining in the presence of 'return' statementsBrian Paul
Before, the presence of a 'return' statement always prevented inlining a function. This was because we didn't want to accidentally return from the _calling_ function. We still need the semantic of 'return' when inlining but we can't always use unconditional branches/jumps (GPUs don't always support arbitrary branching). Now, we allow inlining functions w/ return if the return is the last statement in the function. This fixes the common case of a function that returns a value, such as: vec4 square(const in vec4 x) { return x * x; } which effectively compiles into: vec4 square(const in vec4 x) { __retVal = x * x; return; } The 'return' can be no-op'd now and we can inline the function.
2008-05-20fix incorrect sampler numbering/indexing.Brian Paul
All samplers indexes were zero.
2008-05-16fix assertion typo: s/=/==/Brian Paul
2008-05-14Updated GLSL uniform/sampler handling from gallium-0.1 branchBrian Paul
Previously, the shader linker combined the uniforms used by the vertex and fragment shaders into a combined set of uniforms. This made the implementation of glUniform*() simple, but was rather inefficient otherwise. Now each shader gets its own set of uniforms (no more modelview matrix showing up in the fragment shader uniforms, for example). cherry-picked by hand from gallium-0.1 branch
2008-04-03rewrite some of the mat*mat, mat*vec intrinsicsBrian
Also, remove obsolete matrix codegen code.

2007-05-01Rewrite of slang_inline_asm_function() to do full parameter/argument ↵Brian
substitution. We had been taking a short-cut w/ asm inlines by just using parameters in order rather than doing full formal parameter -> actual argument substitution like ordinary inlined function calls. This worked in all cases but one: mix() in which the parameters were used in a different order. This fixes bug 10821.

Also, found/fixed a code generation regression: the emit_swizzle() function was always returning NULL. This caused emit_move() to miss its chance at peephole optimization.
