+Since `fp` can hold either type of function, the compiler might generate code
 to save and clear registers in preparation for a security state transition even
 if the function call nevers performs such transition at run-time.
 
 To mitigate this, an nsfptr provides a way to test at run-time the

 this pointer. By using the nsfptr related intrinsics, it is
