How to check if move constructor is autogenerated?

Is move contructor autogenerated ???

cppreference documentation

Types without a move constructor, but with a copy constructor that accepts const T& arguments, satisfy std::is_move_constructible

class X{
public:
     ~X()=default;

};

So i want to know if std::is_move_constructible::value is true because X genuinely has a default move constructor, not because it has a default a copy constructor?
