Bug ID: 119113
Summary: missed optimization with `pointer to member function`
with non-direct usage
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Keywords: missed-optimization
Severity: enhancement
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
Take:
```
struct TestObject {
void f() const { }
};
TestObject p;
void (TestObject::*pmf)() const = &TestObject::f;
void doTest1() {
((&((void)1, p))->*(pmf))();
}
void doTest2() {
((&(p))->*(pmf))();
}
```
Both should be optimized to so there is no check that pmf is virtual method but
doTest1 still has the check.
