* glsl: Add implementation of inverse() for mat2/3/4.Eric Anholt2012-04-241-0/+4
| | | | | | | | | | | | This is taken from the ogl-math project, with Inverse renamed to adj (since it's not actually the inverse), transposed, and our types plugged in. There are potential CSE opportunities in this code (particularly for hardware with RCP but not DIV), but we should be doing CSE anyway, so don't hand-optimize. Fixes piglit inverse tests.

* glsl/builtins: Rework profiles to use the new '.glsl' common suffix.Kenneth Graunke2012-04-1720-4807/+1902
| | | | | | | | | | | | | | | | | | | | Deletes a lot of pointless duplication, as well as some run-time effort. Conveniently, GLSL 1.40 no longer needs a .vert variant, since it doesn't define any built-ins specific to the vertex shader stage. ARB_texture_rectangle and OES_EGL_image_external also only need a single profile, since the .vert and .frag variants were identical. I didn't bother with EXT_texture_array and OES_texture_3D because they're so tiny that the savings would be miniscule. Cuts the generated builtin_function.cpp from 1.7MB to 1.0MB (41%).

* glsl/builtins: Use ivec for texel offsets in textureProjGradOffset.Kenneth Graunke2012-04-173-4/+4
| | | | | | | | | | | | | | | | | The GLSL 1.30 -> 4.10 specs all erroneously say "vec2" for a few overloads of textureProjGradOffset, while most overloads and all other texturing functions use ivec types. The GLSL 4.20 specification corrects these to "ivec2", but doesn't mention this as being a conscious change in behavior. Nor does the ARB_shading_language_420pack extension. So presumably it was a typo. At any rate, our builtin functions all use ivec already, so the fact that these prototypes use plain vecs will only lead to applications dying in a fire when trying to use them.

* glsl: Add remaining *sampler2DRect* texture functions.Eric Anholt2012-04-162-0/+136
| | | | | | Fixes the new piglit texelFetch() tests on these. Note that the rest of the new functions are not tested (same as the non-2DRect versions of most of them).
* glsl: Fix the prototype of textureProjGradOffset(sampler2DShadow)Eric Anholt2012-04-161-1/+1
| | | | | | | Indirectly caught by Ken's review of my GLSL 1.40 changes where I copy-and-pasted this line. Reviewed-by: Kenneth Graunke <[email protected]>
* glsl: Add textureSize(*samplerBuffer) support.Eric Anholt2012-04-162-0/+8
| | | | | | Fixes the corresponding new tests in piglit. Reviewed-by: Kenneth Graunke <[email protected]>
* glsl: Add texelFetch(*samplerBuffer) entrypoints to GLSL 1.40.Eric Anholt2012-04-092-0/+8
| | | | | | | | Fix texelFetch(sampler2DRect) and textureSize(samplerBuffer) generation to not reference a LOD at the same time because it's easier than not fixing it. Reviewed-by: Kenneth Graunke <[email protected]>
* glsl: Add GLSL 1.40 textureSize() implementations for sampler2DRect.Eric Anholt2012-03-152-0/+10
| | | | | | | | | | | | | By setting lod to 0 in the builtin function implementation, we avoid needing to update all the visitors to ignore LOD in this case, when the hardware drivers actually want to ask for LOD 0 for rectangular textures. Fixes piglit spec/GLSL-1.40/textureSize-*Rect. v2: Change style of looking for substrings. Reviewed-by: Kenneth Graunke <[email protected]>
* glsl: Drop ftransform() from GLSL 1.40 profile.Eric Anholt2012-03-151-2/+0
| | | | | | | | | This is the one builtin function claimed to be dropped due to the ARB_compatibility split. Fixes piglit spec/GLSL-1.40/compiler/ftransform.vert Reviewed-by: Kenneth Graunke <[email protected]>
* glsl: Copy GLSL 1.30 builtin profile to GLSL 1.40.Eric Anholt2012-03-152-0/+1946

* glsl/builtins: Add missing mix(genType, genType, bvec) built-ins.Kenneth Graunke2012-01-062-0/+10
| | | | | | | | | | | | The IR for mix(float, float, bool) was missing a write mask, causing the IR reader to die horribly. Furthermore, I neglected to add any of the new prototypes to the 1.30 profiles. Fixes oglconform's glsl-bif-com advanced.mix test cases.

* glsl: Remove textureGradOffset built-ins taking samplerCube parameters.Kenneth Graunke2011-11-102-8/+0
| | | | | | | | | These simply don't exist in the 1.30 specification---none of the Offset variants allow samplerCube. This must have been a cut and paste error from textureGrad, which /does/ allow cubemaps. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Paul Berry <[email protected]>
* glsl: Fix misnamed textureProjOffset prototypes in built-in profiles.Kenneth Graunke2011-11-102-62/+62
| | | | | | | | Due to a cut and paste error, these were accidentally misnamed textureProj() rather than textureProjOffset(). Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Paul Berry <[email protected]>
* glsl: Remove texture built-ins with 'bias' from 1.30 VS profile.Kenneth Graunke2011-11-101-118/+4
| | | | | | | | | | | From the GLSL 1.30 spec, section 8.7 "Texture Lookup Functions": "In all functions below, the bias parameter is optional for fragment shaders. The bias parameter is not accepted in a vertex shader." This was a cut and paste mistake. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Paul Berry <[email protected]>

* glsl: Add isinf() and isnan() builtins.Paul Berry2011-10-312-4/+0
| | | | | | | | | | | | | The implementations are as follows: isinf(x) = (abs(x) == +infinity) isnan(x) = (x != x) Note: the latter formula is not necessarily obvious. It works because NaN is the only floating point number that does not equal itself. Fixes piglit tests "isinf-and-isnan fs_basic" and "isinf-and-isnan vs_basic".

* glsl2: Rework builtin function generation.Kenneth Graunke2010-08-138-0/+1530
Each language version/extension and target now has a "profile" containing all of the available builtin function prototypes. These are written in GLSL, and come directly out of the GLSL spec (except for expanding genType). A new builtins/ir/ folder contains the hand-written IR for each builtin, regardless of what version includes it. Only those definitions that have prototypes in the profile will be included. The autogenerated IR for texture builtins is no longer written to disk, so there's no longer any confusion as to what's hand-written or generated. All scripts are now in python instead of perl.
