Changed paths:
M llvm/lib/Transforms/Utils/SimplifyCFG.cpp
Log Message:
-----------
Reapply [SimplifyCFG] Handle branch on same condition in pred more directly
Reapplying without changes, after a fix to a dependent patch.
-----
Rather than creating a PHI node and then using the PHI threading
code, directly handle this case in
FoldCondBranchOnValueKnownInPredecessor().
This change is supposed to be NFC-ish, but may cause changes due
to different transform order.
