From: Chia-I Wu <o...@lunarg.com> Hi,
This series of patches implements the emulation SIMD16 sample_d with dual SIMD8 sample_d. Before the changes, the compiler would fail to generate SIMD16 code for fragment shaders that use textureGrad. And that hurts the performance. The first four patches prepare the compiler for supporting SIMD8 sampler messages in SIMD16 mode. The last two patches implement the emulation. For some changes, there are more than one way to achieve the same goals. That is why this series is marked RFC. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
