This was a bit of follow-on work that I had wanted to do back when I did all the other uniform rework. Setting the initial values for uniforms (that have initializers in the GLSL code) is moved from ir_to_mesa to the linker.
In addition, support for initializers on samplers is added. This gives some small simplification in the ff_fragment_shader code. It will also make re-working the ARB_fragment_program compiler to use GLSL IR a bit easier. In the future, it may also be used to support sampler "bindings" from GL_ARB_shading_language_420pack. I would also like to eventually eliminate the extra indirection of gl_shader_program::SamplerUnits and gl_program::TexturesUsed. That code is intertwined with a bunch of other stuff, and it may have to wait a bit. The supplied unit tests hit most of the cases *except* structures. I intend to add structure tests, but I want to wait until some of Eric's ir_builder work lands. I suspect I'll end up extending that work to make building structures a bit easier as well. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
