The return address is not necessarily a function pointer.

Typically the return address is within a function with the stackframe set up, etc.

Those functions - as you show them - would be called from within the function, which would return, itself?

If you intend to first go to a different function and then jumping back to the original calling function, why not specifying this directly? Or first call the intermediate function and then return?

Having put more thought into it, it would have to be two separate functions:

   auto get_return_address(void) -> void (*)(void);

   void set_return_address(  void (*)(void)  );

You mentioned Control Flow Enforcement -- which by the way I've never
encountered -- but of course you would turn that off when debugging.
