--- Comment #16 from Richard Biener <rguenth at gcc dot gnu.org> ---
This is fixed now, we produce

.L3:
        vbroadcastsd    (%rsi,%rax), %ymm0
        vmulpd  (%rdi,%rax,4), %ymm0, %ymm0
        vmovupd %ymm0, (%rdi,%rax,4)
        addq    $8, %rax
        cmpq    %rdx, %rax
        jne     .L3
