[...@gnu-6 pr39146]$ cat bar.i
typedef long long __m256i __attribute__ ((__vector_size__ (32),
__may_alias__));


__m256i
bar (__m256i y, __m256i x)

  return x;

        .type   bar, @function
bar:
        pushl   %ebp
        movl    %esp, %ebp
        andl    $-32, %esp
        movl    8(%ebp), %eax
        vmovdqa %ymm1, (%eax)
        movl    %ebp, %esp
        popl    %ebp
        ret     $4
        .size   bar, .-bar

__m256 should be returned in ymm0.
