[PATCH] D30631: [BPI] Use metadata info before any other heuristics

[Serguei Katkov via Phabricator via llvm-commits]

skatkov added a comment.

The problem I see here is that calcUnreachableHeuristics computes PostDominatedByUnreachable and if metadata is present then we miss this computation. From other point of view if metadata is present than it is better to use it. So the problem is when metadata is present in some cases but no in all cases.
