OK.  I think I get it.  

EH_RETURN_HANDLER_RTX is just $ra on the MIPS, right?

And then I need to gussy up the epilogue to check for
current_function_calls_eh_return, and then make sure the
EH_STACKADJ_RTX is added to $sp on the way out.

Do I do that instead of the normal add to $sp that pops the current
stack frame, or in addition to it?

Thanks,
