--- Comment #11 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
I'm going to add a testcase that ensures that we don't warn for

struct X {
  X() { }
  X(const X&) { }
  X(const X&&) { }
};

const X x;
const X y = std::move(x);

but otherwise I don't see any useful extension to our std::move warnings.
