c++: DECL_FRIEND_P cleanup
DECL_FRIEND_P's meaning has changed over time. It now (almost) means the the friend function decl has not been met via an explicit decl. This completes that transition, renaming it to DECL_UNIQUE_FRIEND_P, so one doesn't think it is the sole indicator of friendliness (plenty of friends do not have the flag set). This allows reduction in the complexity of managing the field -- all in duplicate_decls now. gcc/cp/ * cp-tree.h (struct lang_decl_fn): Adjust context comment. (DECL_FRIEND_P): Replace with ... (DECL_UNIQUE_FRIEND_P): ... this. Only for FUNCTION_DECLs. (DECL_FRIEND_CONTEXT): Adjust. * class.c (add_implicitly_declared_members): Detect friendly spaceship from context. * constraint.cc (remove_constraints): Use a checking assert. (maybe_substitute_reqs_for): Use DECL_UNIQUE_FRIEND_P. * decl.c (check_no_redeclaration_friend_default_args): DECL_UNIQUE_FRIEND_P is signficant, not hiddenness. (duplicate_decls): Adjust DECL_UNIQUE_FRIEND_P clearing. (redeclaration_error_message): Use DECL_UNIQUE_FRIEND_P. (start_preparsed_function): Correct in-class friend processing. Refactor some initializers. (grokmethod): Directly check friend decl-spec. * decl2.c (grokfield): Check DECL_UNIQUE_FRIEND_P. * friend.c (do_friend): Set DECL_UNIQUE_FRIEND_P first, remove extraneous conditions. Don't re set it afterwards. * name-lookup.c (lookup_elaborated_type_1): Simplify revealing code. (do_pushtag): Likewise. * pt.c (optimize_specialization_lookup_p): Check DECL_UNIQUE_FRIEND_P. (push_template_decl): Likewise. Drop unneeded friend setting. (type_dependent_expression_p): Check DECL_UNIQUE_FRIEND_P. libcc1/ * libcp1plugin.cc (plugin_add_friend): Set DECL_UNIQUE_FRIEND_P.
