            Bug ID: 113379
           Summary: `MIN<a,b> == MAX<a,b>` should be optimzed to `a == b`
           Product: gcc
           Version: 14.0
            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 f(int a, int b)
{
        int c = a > b ? a : b;
        int d = a < b ? a : b;
        return c == d;
}
```

This should be optimized to `a == b;`

Likewise for the `!=` case too.
