* mesa: move shader/slang/* sources to main/slang/*Brian Paul2010-06-1010-7327/+0
| | | | Reduce the source tree depth a bit.
* glsl: avoid using rcp in length() functionsBrian Paul2010-03-291-3/+3
| | | | See prev commit for related info.
* glsl: remove rcp from sqrt()Brian Paul2010-03-291-10/+4
| | | | | | | Per a patch from Marek Olšák, we can simply multiply the incoming value by 1/sqrt(x) instead of using rcp. We're keeping the x==0 check to avoid generating NaN for sqrt(0).

* glsl: implement support for GL_EXT_texture_arrayBrian Paul2010-02-253-0/+96
| | | | | | | | GL_EXT_texture_array is different from the existing GL_MESA_texture_array support in that the former is only supported for GLSL, not fixed-function. The shadow compare versions of the sampler functions haven't been tested yet. The non-shadow versions have been tested with a new piglit test.

| | | | | | This file has been modified in master and removed in feature branch. This gave a merge conflict I couldn't resolve by removing and git adding it to index.

| * glsl: rewrite sqrt(x) intrinsic to handle x=0Brian Paul2009-09-291-34/+42
| | | | | | | | | | | | 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.
* | scons: Get GLSL code building correctly when cross compiling.José Fonseca2009-12-101-0/+8
| | | | | | | | | | This is quite messy. GLSL code has to be built twice: one for the host OS, another for the target OS.

* glsl: fix typo: s/vec4_tex1d_proj/vec4_tex_1d_proj/Brian Paul2009-03-102-24/+24
| | | | This regression came from commit c0b59420eec5ffdf22a5919d38851c3620b97c09.
* glsl: use new IR opcodes for TEX instructions with shadow comparisonBrian Paul2009-02-206-165/+165
| | | | | | Such TEX instructions will have the TexShadow flag set. The gl_program::ShadowSamplers field is now set in the linker. We missed that before.

| * glsl: fix broken +=, -=, *=, /= operatorsBrian Paul2009-01-082-737/+786
| | | | | | | | | | | | | | These functions need to return the final computed value. Now expressions such as a = (b += c) work properly. Also, no need to use __asm intrinsics in these functions. The resulting code is the same when using ordinary arithmetic operators and is more legible.

| * mesa: allow variable indexing into the predefined uniform variable arraysBrian Paul2008-12-302-54/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
