If you enable sub-reg liveness in this branch: http://cgit.freedesktop.org/~tstellar/llvm/log/?h=sched-perf-Mar-27-2015, do you still see the bugs?
In unigine valley there is not corruption with that anymore, perf goes down by 5% just to mention...
But all other bugs are still there like corruptions in Stacking and Hands of Fate games and all same piglit tests still fail.
