Author: Kenneth Graunke <[email protected]> Date: Thu Jul 17 14:33:15 2014 -0700 i965: Enable INTDIV in SIMD16 mode. All we need to do is decompose this to two SIMD8 instructions, like we do in many other cases. We even already have code for that. I apparently just botched this last time I tried, and it was easy.
