Andrea Di Biagio 1726e2ff15 [X86] Add two combine rules to simplify dag nodes introduced during type legalization when promoting nodes with illegal vector type. ... This patch teaches the backend how to simplify/canonicalize dag node sequences normally introduced by the backend when promoting certain dag nodes with illegal vector type. This patch adds two new combine rules: 1) fold (shuffle (bitcast (BINOP A, B)), Undef, <Mask>) -> (shuffle (BINOP (bitcast A), (bitcast B)), Undef, <Mask>) 2) fold (BINOP (shuffle (A, Undef, <Mask>)), (shuffle (B, Undef, <Mask>))) -> (shuffle (BINOP A, B), Undef, <Mask>). Both rules are only triggered on the type-legalized DAG. In particular, rule 1. is a target specific combine rule that attempts to sink a bitconvert into the operands of a binary operation. Rule 2. is a target independet rule that attempts to move a shuffle immediately after a binary operation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209930 91177308-0d34-0410-b5e6-96231b3b80d8		2014-05-30 23:17:53 +00:00
