[PATCH] D94619: [SplitEdge] Update SplitCriticalEdge to return a nullptr only when the edge is not critical

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

Could use an IR test. Is only CoroFrame.cpp affected?
I'd recommend to split this up into NFC refactoring patch, and the actual functionality change.
