* glsl: Improve the accuracy of the acos() approximation.Francisco Jerez2016-03-031-1/+1
| | | | | | | | | | | | | | | | The adjusted polynomial coefficients come from the numerical minimization of the L2 norm of the relative error. The old coefficients would give a maximum relative error of about 15000 ULP in the neighborhood around acos(x) = 0, the new ones give a relative error bounded by less than 2000 ULP in the same neighborhood.

* glsl: Parameterize asin_expr() on the fit coefficients.Kenneth Graunke2016-03-031-6/+6
| | | | | | | | | | | | This will allow us to share the implementation while using different polynomials for asin() and acos(). Francisco Jerez did this in the SPIR-V front-end; I'm merely porting his idea to the GLSL world.

* mesa: add GL_OES_gpu_shader5 and GL_EXT_gpu_shader5 supportIlia Mirkin2016-02-271-47/+58
| | | | | | | | | | | The two extensions are identical, and are largely taking bits of already existing desktop functionality. We continue to do a poor job of supporting the 'precise' keyword, just like we do on desktop. This passes the relevant dEQP tests that I could find.

* glsl: Implement the required built-in functions when OES_shader_image_atomic ↵Francisco Jerez2016-02-221-18/+43
| | | | | | | | | | | | | | | | | | | | | | is enabled. This is basically just the same atomic functions exposed by ARB_shader_image_load_store, with one exception: "highp float imageAtomicExchange( coherent IMAGE_PARAMS, float data);" There's no float atomic exchange overload in the original ARB_shader_image_load_store or GL 4.2, so this seems like new functionality that requires specific back-end support and a separate availability condition in the built-in function generator. v2: Move image availability predicate logic into a separate static function for clarity. Had to pull out the image_function_flags enum from the builtin_builder class for that to be possible. Reviewed-by: Ilia Mirkin <imirkin@alum.mit.edu>
* glsl/types: Rename sampler_type to sampled_typeJason Ekstrand2016-02-131-2/+2
| | | | | | | | It's a bit more descriptive since it is the base type that you get when you sample from it. Also, the next commit adds a bare "sampler" type and we need glsl_type::sampler_type available for a public static member. Reviewed-by: Jordan Justen <jordan.l.justen@intel.com>
