[SystemZ] computeKnownBitsForTargetNode() / ComputeNumSignBitsForTargetNode() Improve/implement these methods to improve DAG combining. This mainly concerns intrinsics. Some constant operands to SystemZISD nodes have been marked Opaque to avoid transforming back and forth between generic and target nodes infinitely. Review: Ulrich Weigand llvm-svn: 327765
2018-03-17 16:32:12 +08:00
; Test that DAGCombiner gets helped by computeKnownBitsForTargetNode() with
; vector intrinsics.
