Hal Finkel fc3b7bbf49 UpdatePHINodes in BasicBlockUtils should not crash on duplicate predecessors ... UpdatePHINodes has an optimization to reuse an existing PHI node, where it first deletes all of its entries and then replaces them. Unfortunately, in the case where we had duplicate predecessors (which are allowed so long as the associated PHI entries have the same value), the loop removing the existing PHI entries from the to-be-reused PHI would assert (if that PHI was not the one which had the duplicates). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192001 91177308-0d34-0410-b5e6-96231b3b80d8		2013-10-04 23:41:05 +00:00
