Juergen Ributzka d0995fb982 [SwitchLowering] Fix the "fixPhis" function. ... Switch statements may have more than one incoming edge into the same BB if they all have the same value. When the switch statement is converted these incoming edges are now coming from multiple BBs. Updating all incoming values to be from a single BB is incorrect and would generate invalid LLVM IR. The fix is to only update the first occurrence of an incoming value. Switch lowering will perform subsequent calls to this helper function for each incoming edge with a new basic block - updating all edges in the process. This fixes rdar://problem/18916275. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@221627 91177308-0d34-0410-b5e6-96231b3b80d8		2014-11-10 21:05:27 +00:00
