From 3353626a6a2cc20301c65f3f6c1c5beb80721181 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 18 Jan 2012 14:42:26 -0800 Subject: i965/vs: Enable workaround-free math on gen7. This is similar to a commit that did the same for the FS. Shaves several more instructions off of the VS in Lightsmark, but no statistically significant performance difference (n=5).
