From: Ulrich Weigand <uweigand@de.ibm.com>
Date: Thu, 2 Jul 2009 17:02:29 +0000
Subject: 	* 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.
