--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
here is another related testcase but this was the exactly reduced one from
bitmap_single_bit_set_p :
```
_Bool f(unsigned a, int t)
{
void g(void);
if (t)
return 0;
g();
if (a > 1)
return 0;
return a == 1;
}
```
this should be optimized down to:
```
_Bool f(unsigned a, int t)
{
void g(void);
if (t)
return 0;
g();
return a == 1;
}
```
