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.
