* 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.
(dr_reg_base_num, fv_reg_base_num): Move to earlier in the file.
