Hans Wennborg 57933e3481 SimplifyCFG: Don't generate invalid code for switch used to initialize ... two variables where the first variable is returned and the second ignored. I don't think this occurs in practice (other passes should have cleaned up the unused phi node), but it should still be handled correctly. Also make the logic for determining if we should return early less sketchy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164225 91177308-0d34-0410-b5e6-96231b3b80d8		2012-09-19 14:24:21 +00:00
