2010-07-22glsl2: Refresh autogenerated file builtin_function.cpp.Kenneth Graunke
2010-07-22glsl2: Fix the type of (1.0 - arg2) for mix(gen, gen, float).Eric Anholt
Previously, we'd constant-fold up a value of vec4(1.0 - arg2, 0, 0, 0). Fixes: glsl1-mix(vec4) function
2010-07-21linker: Link built-in functions instead of including them in every shaderIan Romanick
This is an invasive set of changes. Each user shader tracks a set of other shaders that contain built-in functions. During compilation, function prototypes are imported from these shaders. During linking, the shaders are linked with these built-in-function shaders just like with any other shader.
2010-07-20glsl2: Fix asin() implementation.Eric Anholt
I'd flipped around the order of two operations in paren-balancing adventures, and left out the multiply by sign(x) required for negative x. Fixes: glsl1-acos(vec4) function glsl1-asin(vec4) function glsl1-atan(vec4) function
2010-07-20glsl2: notEqual() produces a boolean value, not the base type of the args.Eric Anholt
Fixes: glsl1-vector relational (bvec2 ==,!=) glsl1-vector relational (vec4 !=)
2010-07-19glsl2: Use Elements macroIan Romanick
2010-07-19glsl2: Fix the expression type for atan's pi * sign(y).Eric Anholt
Fixes CorrectFunction.vert.
2010-07-18glsl2: Make cross() be an expression operation.Eric Anholt
ARB_fp, ARB_vp, Mesa IR, and the 965 vertex shader all have instructions for cross. Shaves 12 Mesa instructions off of a 66-instruction shader I have.
2010-07-14Refresh autogenerated file builtin_function.cpp.Kenneth Graunke
2010-07-07glsl: Fix the setup of refract()'s output for vec3/vec4 and k < 0.0.Eric Anholt
caught by valgrind.
2010-07-02Refresh autogenerated file builtin_function.cpp.Kenneth Graunke
2010-07-01glsl2: Add ir_unop_fract as an expression type.Eric Anholt
Most backends will prefer seeing this to seeing (a - floor(a)), so represent it explicitly.
2010-06-30glsl2: Don't break sign() down by vector components.Eric Anholt
2010-06-30glsl2: Fix reversed value of step().Eric Anholt
It's 0.0 if x < edge, not 1.0. Partial fix for glsl-fs-step.
2010-06-30glsl2: Fix up the implementation of fract() for vector types.Eric Anholt
There's no need to split each vector component out, just do vector ops.
2010-06-24glsl2: Move the compiler to the subdirectory it will live in in Mesa.Eric Anholt
