            Bug ID: 110937
           Summary: (bool0 ? bool1^1 : bool1) is not optimized to bool0 ^
                    bool1
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Keywords: missed-optimization
          Severity: enhancement
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

Take:
```
_Bool f2(_Bool a, _Bool b)
{
        if (a)
          return !b;
        return b;
}
```
This should be optimized to just:
```
_Bool f2_(_Bool a, _Bool b)
{
  return a ^ b;
}
```=
