Chandler Carruth 72753f87f2 [SDAG] Teach the SelectionDAG to canonicalize vector shuffles of splats ... directly into blends of the splats. These patterns show up even very late in the vector shuffle lowering where we don't have any chance for DAG combining to kick in, and blending is a tremendously simpler operation to model. By coercing the shuffle into a blend we can much more easily match and lower shuffles of splats. Immediately with this change there are significantly more blends being matched in the x86 vector shuffle lowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@229308 91177308-0d34-0410-b5e6-96231b3b80d8		2015-02-15 12:18:12 +00:00
