Subject: 	* emit-rtl.c (last_label_num, base_label_num): Remove.
X-Git-Url: http://git.sourceforge.jp/view?a=commitdiff_plain;h=3f10251fc4107d5b49214cbc8d8e5338593edf27;p=pf3gnuchains%2Fgcc-fork.git

	* emit-rtl.c (last_label_num, base_label_num): Remove.
	(max_label_num): Always return label_num.
	(set_new_last_label_num, restore_emit_status): Remove.
	(init_emit): Don't initialize last_label_num.
	* function.c (pop_function_context_from): Don't call
	restore_emit_status.
	* function.h: Remove the prototype for restore_emit_status.
	* rtl.h: Remove the prototype for set_new_last_label_num.
