--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.

Note if you use float instead of double. GCC produces better code. That is the
following testcase:
int check (char *mask, float *result, int n) {
    int count = 0;
    for (int i=0; i<n; i++) {
        if (mask[i] == 0 && result[i] != 2.0)
          count++;
    }
    return count;
}

So GCC could do this; just misses the 64bit case ...
