--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
here is another missed optimization:
```
_Bool f2(int a, int b)
{
        _Bool t = a == b;
        unsigned t1 = a;
        unsigned t2 = b;
        _Bool b2 = t1 >= t2;
        return t & b2;
}
```
This should just be optimized to `return a == b;`.
