From 6431177a552eca9ee9d4b1fde8255f98363e4c34 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Tue, 2 Oct 2001 08:12:25 +0100 Subject: attribs.c (decl_attributes): Possibly call insert_default_attributes to insert default attributes on... * attribs.c (decl_attributes): Possibly call insert_default_attributes to insert default attributes on functions in a lazy manner. * builtin-attrs.def: New file; define the default format and format_arg attributes. * c-common.c (c_format_attribute_table): Move to earlier in the file. (c_common_nodes_and_builtins): Initialize format_attribute_table. (enum built_in_attribute, built_in_attributes, c_attrs_initialized, c_init_attributes, c_common_insert_default_attributes): New. (c_common_lang_init): Don't initialize format_attribute_table. Do call c_init_attributes. * Makefile.in (c-common.o): Depend on builtin-attrs.def. * c-common.h (init_function_format_info): Don't declare. (c_common_insert_default_attributes): Declare. * c-decl.c (implicitly_declare, builtin_function): Call decl_attributes. (init_decl_processing): Don't call init_function_format_info. (insert_default_attributes): New. * c-format.c (handle_format_attribute, handle_format_arg_attribute): Be quiet about inappropriate declaration when applying default attributes. (init_function_format_info): Remove. * tree.h (enum attribute_flags): Add ATTR_FLAG_BUILT_IN. (insert_default_attributes): Declare. cp: * decl.c (init_decl_processing): Don't call init_function_format_info. Initialize lang_attribute_table earlier. (builtin_function): Call decl_attributes. (insert_default_attributes): New. testsuite: * gcc.dg/format/attr-5.c, gcc.dg/format/attr-6.c: New tests.
