--- Comment #14 from CVS 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:7abcc9ca20d4e17deabb308b5f483aaccc3dc02c commit r12-5597-g7abcc9ca20d4e17deabb308b5f483aaccc3dc02c Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Nov 30 09:50:52 2021 +0100 libcpp: Enable P1949R7 for C++11 and up as it was a DR [PR100977] Jonathan mentioned on IRC that: "Accept P1949R7 (C++ Identifier Syntax using Unicode Standard Annex 31) as a Defect Report and apply the changes therein to the C++ working paper." while I've actually implemented it only for -std={gnu,c}++{23,2b}. As the C++98 rules were significantly different, I'm not trying to change anything for C++98. 2021-11-30 Jakub Jelinek <ja...@redhat.com> PR c++/100977 * init.c (lang_defaults): Enable cxx23_identifiers for -std={gnu,c}++{11,14,17,20} too. * c-c++-common/cpp/ucnid-2011-1-utf8.c: Expect errors in C++. * c-c++-common/cpp/ucnid-2011-1.c: Likewise. * g++.dg/cpp/ucnid-4-utf8.C: Add missing space to dg-options. * g++.dg/cpp23/normalize3.C: Enable for c++11 rather than just c++23. * g++.dg/cpp23/normalize4.C: Likewise. * g++.dg/cpp23/normalize5.C: Likewise. * g++.dg/cpp23/normalize7.C: Expect errors rather than just warnings for c++11 and up rather than just c++23. * g++.dg/cpp23/ucnid-2-utf8.C: Expect errors even for c++11 .. c++20.
