From 3bbfbb92b3cf687215142bcd8dfe720cf9cdc6b0 Mon Sep 17 00:00:00 2001 From: Elena Zannoni Date: Thu, 12 Jul 2001 02:29:33 +0000 Subject: [PATCH] 2001-07-11 Elena Zannoni * config/sh/tm-sh.h (struct gdbarch_tdep): Add FLOAT_ARGLAST_REGNUM, RETURN_REGNUM, ARG0_REGNUM, ARGLAST_REGNUM, PR_REGNUM fields. * sh-tdep.c (sh_skip_prologue_hard_way): Rename from skip_prologue_hard_way(). (skip_prologue_hard_way): Make it a function pointer. (sh_print_register): Use function pointer do_pseudo_register, instead of sh_do_pseudo_register. (sh_do_registers_info): Ditto. (sh_gdbarch_init): Initialize do_pseudo_register. (IS_MOV_TO_R14): Rename from IS_MOV_R14. (skip_prologue_hard_way): Update. (sh_gdbarch_init): Move setting of frame_chain, get_saved_register, init_extra_frame_info, push_arguments, extract_return_value, pop_frame, store_struct_return, extract_struct_value_address, use_struct_convention, init_extra_frame_info to before target specific settings. (sh_gdbarch_init): Initialize new tdep fields FLOAT_ARGLAST_REGNUM, RETURN_REGNUM, ARG0_REGNUM, ARGLAST_REGNUM, PR_REGNUM. (sh_push_arguments): Use new gdbarch_tdep fields {ARG0,ARGLAST}_REGNUM. (sh_saved_pc_after_call, sh_nofp_frame_init_saved_regs, sh_init_extra_frame_info, sh_push_return_address, sh_generic_show_regs, sh3_show_regs, sh3e_show_regs, sh3_dsp_show_regs, sh4_show_regs, sh_dsp_show_regs): Update to use gdbarch_tdep->PR_REGNUM.
