graph.c (node_data): Return void.
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.
