Chandler Carruth 46d3e580ed [x86] When splitting 256-bit vectors into 128-bit vectors, don't extract ... subvectors from buildvectors. That doesn't really make any sense and it breaks all of the down-stream matching of buildvectors to cleverly lower shuffles. With this, we now get the shift-based lowering of 256-bit vector shuffles with AVX1 when we split them into 128-bit vectors. We also do much better on the zero-extension patterns, although there remains quite a bit of room for improvement here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@229299 91177308-0d34-0410-b5e6-96231b3b80d8		2015-02-15 10:12:02 +00:00
