[PATCH] D38563: [MachineBlockPlacement] Make sure PreferredLoopExit is cleared everytime new loop is processed

[Serguei Katkov via Phabricator via llvm-commits]

skatkov added a comment.

I believe that added assert is invalid. PreferredLoopExit might be easily part of the loop L if it was not added to hot chain. In other words pass decided to layout this BB in a scope of outer loop or function at all.

If you agree with me, please fix this asap.
