--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
What is interesting is clang does not even do it for:
int f2(int x)
{
    int t = 0;
    if ((unsigned)x > 15)
        t= false;
    else t = ~x;
    return t&1;
}

But once you change int to bool, it does .....
We might be able to do it for both.
