[PATCH] D57982: [SanitizierCoverage] Avoid splitting critical edges when destination is a basic block containing unreachable

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

A block can end in unreachable, but still have reachable code at the beginning. If the block calls a function that is known not to return, the next instruction after the call will be UnreachableInst. For example https://godbolt.org/z/6AGtOf
