% Loop and "POP 0,0" until rO is the expected value, like
% the expansion of nonlocal_goto_receiver, except that we put the return
% value in the right register and make sure that the POP causes it to
% enter the right return-value register as seen by the caller. For the
% GNU ABI, it is unnecessary to do this in the loop and perhaps the memory
% access can be hoisted outside the loop, but this is safe and simple and
% I see no need to optimize longjmps.
