            Bug ID: 109959
           Summary: `(a > 1) ? 0 : (a == 1)` is not optimized when spelled
                    out
           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 f(unsigned a)
{
        if (a > 1)
          return 0;
        return a == 1;
}


_Bool f0(unsigned a)
{
  return (a > 1) ? 0 : (a == 1);
}
```
Both of these should just optimize to:
`return a == 1`, f0 is currently.
