* arch-utils.c (selected_byte_order): Return target_byte_order_user.
(show_endian): Use target_byte_order_user if specified; otherwise use get_current_arch () instead of current_gdbarch. (show_architecture): Use set_architecture_string if specified; otherwise use get_current_arch () instead of current_gdbarch. (get_current_arch): New function. * arch-utils.h (get_current_arch): Add prototype. * osabi.c (show_osabi): Use get_current_arch () instead of current_gdbarch. * findcmd.c: Include "arch-utils.h". (parse_find_args): Add BIG_P argument. Use it instead of byte order of current_gdbarch. (find_command): Use get_current_arch () instead of current_gdbarch. Pass byte order to parse_find_args. * maint.c: Include "arch-utils.h". (maintenance_print_architecture): Use get_current_arch () instead of current_gdbarch. * reggroups.c: Include "arch-utils.h". (maintenance_print_reggroups): Use get_current_arch () instead of current_gdbarch. * symfile.c: Include "arch-utils.h". (overlay_load_command): Use get_current_arch () instead of current_gdbarch. * value.c: Include "arch-utils.h". (show_convenience): Use get_current_arch () instead of current_gdbarch. * tui/tui-regs.c: Include "arch-utils.h". (tui_reg_next_command): Use get_current_arch () instead of current_gdbarch. * mi/mi-main.c: Include "arch-utils.h". (mi_cmd_data_read_memory): Use get_current_arch () instead of current_gdbarch. * parse.c: Include "arch-utils.h". (parse_exp_in_context): Use get_current_arch () instead of current_gdbarch.
