Otherwise it looks like the attribute is useless -- it looks like it can only be used for functions where GCC can determine the function does not return anyway. Which means it is redundant.
The purpose of the attribute is to tell the _callers_ of this function that it does not return. It does not change how the attributed function itself is compiled.
