prologue / epilogue / warning patches:
2003-07-16 J"orn Rennecke <joern.rennecke@superh.com>
Con Bradley <con.bradley@superh.com>
* sh-protos.h (sh_get_pr_initial_val): Declare.
* sh.c (regno_reg_class): Make its elements type enum reg_class.
(output_stack_adjust): Remove emit_fn argument. Add epilogue_p
and live_regs_mask arguments. Changed all callers.
(save_schedule_s): New structure.
(save_schedule): New typedef.
(scavenge_reg, sh5_schedule_saves, sh5_schedule_saves): New functions.
(calc_live_regs): For TARGET_SHMEDIA, use leaf_function_p.
In interrupts handlers, also save registers that are usually
partially saved, and make sure there is at least one general purpose
register saved if a target register needs saving.
Add casts in comparisons to avoid warnings.
(sh_media_register_for_return): return -1 for interrupt handlers.
(MAX_SAVED_REGS, MAX_TEMPS): New defines.
(sh_expand_prologue): Use sh5_schedule_saves. Check that any temp
registers used are available.
Set RTX_FRAME_RELATED_P where appropriate.
Add an REG_FRAME_RELATED_EXPR for r0 + offset addressing.
(sh_expand_epilogue, sh_set_return_address): Use sh5_schedule_saves.
(initial_elimination_offset): Likewise.
* sh.h (DWARF_CIE_DATA_ALIGNMENT): Set to -4.
(LOCAL_ALIGNMENT, GENERAL_REGISTER_P): Add casts to avoid warnings.
(FP_REGISTER_P): Add casts to fix broken handling of unsigned REGNO.
(XD_REGISTER_P, TARGET_REGISTER_P): Likewise.
(HARD_REGNO_CALL_PART_CLOBBERED): Also yield nonzero for r15,
and for target registers.
(RETURN_IN_MEMORY): Add parentheses to avoid warnings.
(regno_reg_class): Make its elements type enum reg_class.
(CONSTRAINT_LEN): Don't use isdigit.
(FUNCTION_ARG_REGNO_P): Add casts to avoid warnings.
(FUNCTION_ARG): Add parentheses to avoid warnings.
(RETURN_ADDR_RTX): Use sh_get_pr_initial_val.
(RETURN_ADDR_OFFSET): Define to -1 for TARGET_SH5.
(SH_DBX_REGISTER_NUMBER): Add casts to avoid warnings.
(EH_RETURN_DATA_REGNO): Use unsigned constants to avoid warnings.
* sh.md (xordi3+1): Remove unused variable regno.
(return_media): Check that tr0 is available before using it.
