--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> 2010-11-18 16:48:54 UTC --- I don't think we have any API to add a new insn into prologue or epilogue hashes, guess easiest would be to reuse the old insn (and just change its PATTERN/notes/etc. as needed) in the RTX_FRAME_RELATED_P case.
