With this patch, for this one exact case, we'll generate: blendps %xmm0, %xmm1, $1 instead of: insertps %xmm0, %xmm1, $0 If there's a memory operand available for load folding and we're optimizing for size, we'll still generate the insertps. The detailed performance data motivation for this may be found in D7866; in summary, blendps has 2-3x throughput vs. insertps on widely used chips.
