--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
It is worse on the trunk:
.L2:
movdqu (%rdi), %xmm1
movdqu (%rdi), %xmm0
addq $16, %rdi
paddd %xmm3, %xmm1
paddd %xmm2, %xmm0
blendpd $2, %xmm0, %xmm1
movups %xmm1, -16(%rdi)
cmpq %rdi, %rax
jne .L2
Why two loads from %rdi here?
This is done during RA as far as I can tell.
