--- Comment #5 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:40485378ade83102d7aa30c317f5d6c90c1d232b commit r14-8832-g40485378ade83102d7aa30c317f5d6c90c1d232b Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Feb 6 22:34:55 2024 +0100 c++: Disallow this specifier except for parameter declarations [PR113788] The deducing this patchset added parsing of this specifier to cp_parser_decl_specifier_seq unconditionally, but in the C++ grammar this[opt] only appears in the parameter-declaration non-terminal, so rather than checking in all the callers of cp_parser_decl_specifier_seq except for cp_parser_parameter_declaration that this specifier didn't appear I think it is far easier and closer to what the standard says to only parse this specifier when called from cp_parser_parameter_declaration. 2024-02-06 Jakub Jelinek <ja...@redhat.com> PR c++/113788 * parser.cc (CP_PARSER_FLAGS_PARAMETER): New enumerator. (cp_parser_decl_specifier_seq): Parse RID_THIS only if CP_PARSER_FLAGS_PARAMETER is set in flags. (cp_parser_parameter_declaration): Or in CP_PARSER_FLAGS_PARAMETER when calling cp_parser_decl_specifier_seq. * g++.dg/parse/pr113788.C: New test.
