Owen Anderson d5f8684b16 It is possible for SimplifyCFG to cause PHI nodes to become redundant too late in the optimization ... pipeline to be caught by instcombine, and it's not feasible to catch them in SimplifyCFG because the use-lists are in an inconsistent state at the point where it could know that it need to simplify them. Instead, have CodeGenPrepare look for trivially redundant PHIs as part of its general cleanup effort. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122516 91177308-0d34-0410-b5e6-96231b3b80d8		2010-12-23 20:57:35 +00:00
