[Mesa-dev] [PATCH] i965: Enable faster workaround-free math on Ivybridge.

2011-10-18 Thread Kenneth Graunke
According to the documentation, Ivybridge's math instruction works in SIMD16 mode for the fragment shader, and no longer forbids align16 mode for the vertex shader. The documentation claims that SIMD16 mode isn't supported for INT DIV, but empirical evidence shows that it works fine. Presumably t
