[PATCH] D78806: SplitIndirectBrCriticalEdges: Fix Branch Probability update

[Hiroshi Yamauchi via Phabricator via llvm-commits]

yamauchi added a comment.

Why considering the cases where "target basic block happens to have unset a probability for any of its successors" specifically?

Does the new test TEST(BasicBlockUtils, SplitIndirectBrCriticalEdge) fail before the change in BreakCriticalEdges.cpp (where the target block doesn't seem to have an unset successor)?
