+       * sh.c (calc_live_regs): If the return address pointer is live,
+       force pr live.
+       (sh5_schedule_saves): Exclude PR_MEDIA_REG from being a temp register
+       for saves / restores.
+       (sh_expand_epilogue): If sh_media_register_for_return returns a
+       register number, flag the instructions that restores PR_MEDIA_REG
+       as possibly dead.
+       Remove dead update of offset.
+       (sh_get_pr_initial_val): Use UNSPEC_RA if we don't know yet if
+       we can use the result of get_hard_reg_initial_val.
+       * sh.md (UNSPEC_RA): New constant.
+       (movsi_i_lowpart+1): Changed into a define_insn_and_split, named:
+       (load_ra).  Handle UNSPEC_RA.
+       (sibcall_media): Use PR_MEDIA_REG.
+
+       * sh.h (CALL_USED_REGISTERS): Include PR_REG and PR_MEDIA_REG.
+       * sh.c (calc_live_regs): Use sh_pr_n_sets to determine if pr
+       needs saving on SHmedia.
