[PATCH] D79037: [StructurizeCFG] Fix region nodes ordering

[Ehud Katz via Phabricator via llvm-commits]

ekatz updated this revision to Diff 266163.
ekatz added a comment.

This is a second take of the solution, using SCCs instead of LoopInfo.
This algorithm can also handle irreducible loops, and, generally, any kind of cycle in the graph.
