[Mesa-dev] [PATCH v2 16/16] i965: Generate vs code using scalar backend for BDW+

2014-11-13 Thread Kristian Høgsberg
With everything in place, we can now use the scalar backend compiler for vertex shaders on BDW+. We make scalar vertex shaders the default on BDW+ but add a new vec4vs debug option to force the vec4 backend. No piglit regressions. Performance impact is minimal, I see a ~1.5 improvement on the T-
