Chandler Carruth 01b3858e66 [x86] Significantly improve the ability of the new vector shuffle ... lowering to match VZEXT_MOVL patterns. I hadn't realized that these had sufficient pattern smarts in the backend to lower zext-ing from the low element of a vector without it being a scalar_to_vector node. They do, and this is how to match a bunch of patterns for movq, movss, etc. There is a weird propensity to end up using pshufd to place the element afterward even though it means domain crossing (or rather, to use xorps+movss to zext the element rather than movq) but that's an orthogonal problem with VZEXT_MOVL that someone should probably look at. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218977 91177308-0d34-0410-b5e6-96231b3b80d8		2014-10-03 11:25:58 +00:00
