Michael Kuperstein d36e24a166 [X86] Avoid folding scalar loads into unary sse intrinsics ... Not folding these cases tends to avoid partial register updates: sqrtss (%eax), %xmm0 Has a partial update of %xmm0, while movss (%eax), %xmm0 sqrtss %xmm0, %xmm0 Has a clobber of the high lanes immediately before the partial update, avoiding a potential stall. Given this, we only want to fold when optimizing for size. This is consistent with the patterns we already have for some of the fp/int converts, and in X86InstrInfo::foldMemoryOperandImpl() Differential Revision: http://reviews.llvm.org/D15741 llvm-svn: 256671		2015-12-31 09:45:16 +00:00
