--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is a few more:
```
int func(bool a, bool b) {
  bool t = b < a;
  return t | a; // a
}
int func1(bool a, bool b) {
  bool t = b < a;
  bool t1 = t < a;
  return t | t1; // a
}


int func2(bool a, bool b) {
  bool t = b > a;
  return t | a; // b | a
}
int func3(bool a, bool b) {
  bool t = b > a;
  bool t1 = t < a;
  return t | t1; // b | a
}
```
