Chandler Carruth 560bddce20 [x86, dag] Teach the DAG combiner to prune inputs toa vector_shuffle ... that are unused. This allows the combiner to delete math feeding shuffles where the math isn't actually necessary. This improves some of the vperm2x128 tests that regressed when the vector shuffle lowering started actually generating vperm instructions rather than forcibly decomposing them. Sadly, this isn't enough to get this *really* right because we still form a completely unnecessary permutation. To fix that, we also need to fold shuffles which just rearrange concatenated or inserted subvectors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@219086 91177308-0d34-0410-b5e6-96231b3b80d8		2014-10-05 19:14:34 +00:00
