--- Comment #3 from Sebastian Dröge (slomo) <slomo at coaxion.net> ---
Might be because we use movdqa here, probably unrolled a bit. We could use
vmovdqa on CPUs that support AVX, but for supporting AVX we would need a
completely separate backend (mixing SSE and AVX instructions makes everything
slower).
