            Bug ID: 113131
           Summary: `((A&B)^C)|B` should be simplified to `C | B`
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Keywords: missed-optimization
          Severity: enhancement
          Priority: P3
         Component: tree-optimization
          Assignee: pinskia at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

Testcase:
```
int f(int A, int B, int C)
{
  return ((A&B)^C)|B; // C|B
}
```

This should be simplified down to `C | B` removing the reference to `A` even.
