	* config/sh/tm-sh.h (struct gdbarch_tdep): Rename fields
        {FP15,DR14,FV12}_REGNUM to {FP,DR,FV}_LAST_REGNUM.
	* sh-tdep.c (sh_sh3e_register_virtual_type,
 	sh_sh4_register_virtual_type, sh_do_registers_info,
 	sh_gdbarch_init, sh_sh4_register_byte, sh_sh4_register_raw_size,
 	sh_sh4_register_convertible, sh_sh4_register_convert_to_virtual,
 	sh_sh4_register_convert_to_raw, sh_fetch_pseudo_register,
 	sh_store_pseudo_register, sh_do_pseudo_register): Ditto.

	* sh-tdep.c (sh_gdbarch_init): Use a function pointer to set the
        disassembly print function.
	(_initialize_sh_tdep): Initialize tm_print_insn using the function
 	pointer.
