Bruno Cardoso Lopes 807360ab08 [x86] Combine x86mmx/i64 to v2i64 conversion to use scalar_to_vector ... Handle the poor codegen for i64/x86xmm->v2i64 (%mm -> %xmm) moves. Instead of using stack store/load pair to do the job, use scalar_to_vector directly, which in the MMX case can use movq2dq. This was the current behavior prior to improvements for vector legalization of extloads in r213897. This commit fixes the regression and as a side-effect also remove some unnecessary shuffles. In the new attached testcase, we go from: pshufw $-18, (%rdi), %mm0 movq %mm0, -8(%rsp) movq -8(%rsp), %xmm0 pshufd $-44, %xmm0, %xmm0 movd %xmm0, %eax ... To: pshufw $-18, (%rdi), %mm0 movq2dq %mm0, %xmm0 movd %xmm0, %eax ...
