hicpp-undelegated-constructor

This check is an alias for bugprone-undelegated-constructor. Partially implements rule 12.4.5 to find misplaced constructor calls inside a constructor.

struct Ctor {
  Ctor();
  Ctor(int);
  Ctor(int, int);
  Ctor(Ctor *i) {
    // All Ctor() calls result in a temporary object
    Ctor(); // did you intend to call a delegated constructor?
    Ctor(0); // did you intend to call a delegated constructor?
    Ctor(1, 2); // did you intend to call a delegated constructor?
    foo();
  }
};
