[PATCH] D54366: RegAllocFast: Add heuristic to detect values not live-out of a block

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

I see regressions with this one after some possibly recent commits? In the first test case in test/CodeGen/AMDGPU/basic-branch.ll, it seems to not detect the use of the pointer value and omits the spill. The restore is still present
