--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
In GCC 8.1 and above we get:
.cfi_startproc
push ebp
.cfi_def_cfa_offset 8
.cfi_offset 5, -8
mov ebp, esp
.cfi_def_cfa_register 5
mov eax, DWORD PTR [ebp+8]
pop ebp
.cfi_restore 5
.cfi_def_cfa 4, 4
vmovaps ymm0, YMMWORD PTR [eax]
vaddsubps ymm0, ymm0, ymm0
ret
So fixed.
