[PATCH] D136069: [AMDGPU] Scheduler: Don't revert the schedule if the register pressure isn't changed for a region

[Valery Pykhtin via Phabricator via llvm-commits]

vpykhtin updated this revision to Diff 468482.
vpykhtin marked 3 inline comments as done.
vpykhtin added a comment.

Rebased, moved the check into shouldRevertScheduling of two stages:

OccInitialScheduleStage
ClusteredLowOccStage

I don't add it to the unclustered stage as this schedule should only be kept if some improvement in RP is achieved.
