--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
vmovupd (%rsi,%rax), %zmm1{%k1}{z}
addq %rdx, %rax
vmovupd (%rax), %zmm2{%k1}{z}
vfmadd132pd %zmm0, %zmm2, %zmm1
vmovupd %zmm1, (%rax){%k1}
isn't optimal btw, it would be nice if we could merge that masking into the
vfmadd132pd instruction, like:
vmovupd (%rsi,%rax), %zmm1{%k1}{z}
addq %rdx, %rax
vfmadd132pd (%rax), %zmm2, %zmm1%{k1}{z}
vmovupd %zmm1, (%rax){%k1}
but not really sure how to achieve that.
