[PATCH] D45649: [Polly][ScopDetect] Reject loop with multiple exit blocks.

[Michael Kruse via Phabricator via llvm-commits]

Meinersbur added a comment.

A BasicBlock that, for instance, terminates with a `ret` or `unreachable`, Polly cannot recognize as a SCoP even if that block would be considered as an error-block, because `RegionInfo` does not create a `Region` for it since it doesn't know about error blocks.
