--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
Here is a run time test:
struct Empty
{
Empty& operator=(const Empty&) = default;
};
template<typename T>
class ShowType;
template<>
struct ShowType<Empty&>{int t = 0;};
template<>
struct ShowType<Empty>{int t = 1;};
int main()
{
ShowType<decltype(Empty() = Empty())> example;
return example.t;
}
---- CUT ----
A compile time test would just remove ShowType<Empty> specialization.
