[C++11]default move constructor as noexcept

Is the default Move constructor defined as noexcept?

An inheriting constructor (12.9) and an implicitly declared special member function (Clause 12) have an exception-specification.

If f is an

• inheriting constructor 
• implicitly declared 
• default constructor
• copy constructor
• move constructor
• destructor
• copy assignment operator
• move assignment operator

its implicit exception-specification specifies the type-id T if and only if T is allowed by the exception-specification of a function directly invoked by f’s implicit definition;

f allows all exceptions if any function it directly invokes allows all exceptions, and f has the exception-specification noexcept(true) if every function it directly invokes allows no exceptions.
