Chris Lattner b58934484b This optimization makes MANY phi nodes that all have the same incoming value. ... If this happens, detect it early instead of relying on instcombine to notice it later. This can be a big speedup, because PHI nodes can have many incoming values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17741 91177308-0d34-0410-b5e6-96231b3b80d8		2004-11-14 19:29:34 +00:00
