            Bug ID: 124460
           Summary: `f = max<f, invariant>` not pulled out of a loop
           Product: gcc
           Version: 16.0
            Status: UNCONFIRMED
          Keywords: missed-optimization
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

Take:
```
int test(int f, int t) {
  for (int o = 0; o < t; o ++) 
    f = (f < 0 ? f : 0);
  return f;
}
```

This should be optimized to just:
```
if (t >= 0)
 f = (f < 0 ? f : 0);
return f;
```
