--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Marek Polacek <mpola...@gcc.gnu.org>: https://gcc.gnu.org/g:adcb497bdba499d161d2e5e8de782bdd6f75d62c commit r12-925-gadcb497bdba499d161d2e5e8de782bdd6f75d62c Author: Marek Polacek <pola...@redhat.com> Date: Tue May 18 16:11:16 2021 -0400 c++: Relax attribute on friend declaration checking [PR100596] It turned out that there are codebases that profusely use GNU attributes on friend declarations, so we have to dial back our checking and allow them. And for C++11 attributes let's just warn instead of giving errors. PR c++/100596 gcc/cp/ChangeLog: * cp-tree.h (any_non_type_attribute_p): Remove. * decl.c (grokdeclarator): Turn an error into a warning and only warn for standard attributes. * decl2.c (any_non_type_attribute_p): Remove. * parser.c (cp_parser_elaborated_type_specifier): Turn an error into a warning and only warn for standard attributes. (cp_parser_member_declaration): Likewise. gcc/testsuite/ChangeLog: * g++.dg/cpp0x/friend7.C: Turn a few dg-warnings into dg-errors. Remove dg-errors for GNU attributes. * g++.dg/ext/attrib63.C: Remove dg-error. * g++.dg/cpp0x/friend8.C: New test.
