The requires clause parsing has code to suggest users wrapping non-primary expressions in (), so if it e.g. parses a primary expression and sees it is followed by ++, --, ., ( or -> among other things it will try to reparse it as assignment expression or what and if that works suggests wrapping it inside of parens. When it is requires-clause that is after <typename T> etc. it already has an exception from that as ( can occur in valid C++20 expression there - starting the parameters of the lambda. In C++23 another case can occur, as the parameters with the ()s can be omitted, requires C can be followed immediately by -> which starts a trailing return type. Even in that case, we don't want to parse that as C->... 2021-04-16 Jakub Jelinek <jakub@redhat.com> PR c++/99850 * parser.c (cp_parser_constraint_requires_parens) <case CPP_DEREF>: If lambda_p, return pce_ok instead of pce_maybe_postfix. * g++.dg/cpp23/lambda-specifiers2.C: New test. |

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
