Chandler Carruth 8f637786d8 [x86] Teach the AVX1 path of the new vector shuffle lowering one more ... trick that I missed. VPERMILPS has a non-immediate memory operand mode that allows it to do asymetric shuffles in the two 128-bit lanes. Use this rather than two shuffles and a blend. However, it turns out the variable shuffle path to VPERMILPS (and VPERMILPD, although that one offers no functional differenc from the immediate operand other than variability) wasn't even plumbed through codegen. Do such plumbing so that we can reasonably emit a variable-masked VPERMILP instruction. Also plumb basic comment parsing and printing through so that the tests are reasonable. There are still a few tests which don't show the shuffle pattern. These are tests with undef lanes. I'll teach the shuffle decoding and printing to handle undef mask entries in a follow-up. I've looked at the masks and they seem reasonable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218300 91177308-0d34-0410-b5e6-96231b3b80d8		2014-09-23 10:08:29 +00:00
