[PATCH] D116819: [AMDGPU] Disable optimizeEndCf at -O0

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

I think this is an extreme interpretation of optnone. This is a minor optimization which happens as part of lowering. The fact we do this as a separate step is just an artifact of how we happen to lower control flow. It's not strictly true that no optimizations occur at -O0, especially if they are cheap and provide benefit
