  Target Milestone: ---

Started between 20220508 and 20220515, with file g++.dg/lookup/friend23.C :


$ cat friend23.C
template <class Derived>

  friend void bar(Derived& d) {
    d.bar(); // access in inline friend of friend, ok?
  }
};

class derived : base<derived> {
  friend class base<derived>;
  void bar() {}
};

int main() {
  derived d;
  bar(d);
}


$ g++-13-20220904 -c friend23.C -mforce-indirect-call -fPIC -fprofile-generate
