Matt Arsenault	c77c471fc2	AMDGPU: Disable scheduling in some slow tests ... Disabling the pre-RA scheduler on large-work-group-registers causes it to be ~50% slower. llvm-svn: 272860	2016-06-16 00:56:47 +00:00
Nicolai Haehnle	498b8e6d32	AMDGPU: Quick fix for extreme slowness in spill-scavenge-offset.ll test ... Summary: Also, some cosmetic fixes.

Nicolai Haehnle	e72d316342	AMDGPU: Release the scavenged offset register during VGPR spill ... Summary: This fixes a crash where subsequent spills would be unable to scavenge a register. In particular, it fixes a crash in piglit's spec@glsl-1.50@execution@geometry@max-input-components (the test still has a shader that fails to compile because of too many SGPR spills, but at least it doesn't crash any more). This is a candidate for the release branch.
