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.
