graph.c (node_data): Return void.

Browse Source 
1999-04-14 23:26 -0400  Zack Weinberg  <zack@rabi.columbia.edu>
	* graph.c (node_data): Return void.  Ignore result of
	print_rtl_single.  Change caller to match.
	* integrate.c (subst_constants): Initialize op0_mode to an
	invalid mode, and abort before use if it's still invalid.
	(Can only happen if the RTX_CLASS, RTX_FORMAT tables are corrupted.)
	* objc/objc-act.c (get_objc_string_decl,
	build_selector_translation_table, generate_protocol_list,
	synth_id_with_class_suffix, build_keyword_selector,
	build_selector_expr, gen_declarator): Abort when the tree
	structure is corrupted.
