--- 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.
