From: "cvs-commit at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/96106] [10/11 Regression] A friend abbreviated template function denies access to private members Date: Tue, 11 Aug 2020 13:37:59 +0000 [thread overview] Message-ID: <bug-96106-4-M4AmKemzsU@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-96106-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96106 --- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Patrick Palka <ppalka@gcc.gnu.org>: https://gcc.gnu.org/g:745ba1024c653324f9f0b88968c6f8989ed1e093 commit r10-8604-g745ba1024c653324f9f0b88968c6f8989ed1e093 Author: Patrick Palka <ppalka@redhat.com> Date: Wed Jul 29 22:06:36 2020 -0400 c++: abbreviated function template friend matching [PR96106] In the below testcase, duplicate_decls wasn't merging the tsubsted friend declaration for 'void add(auto)' with its definition, because reduce_template_parm_level (during tsubst_friend_function) lost the DECL_VIRTUAL_P flag on the auto's invented template parameter, which caused template_heads_equivalent_p to deem the two template heads as not equivalent in C++20 mode. This patch makes reduce_template_parm_level carry over the DECL_VIRTUAL_P flag from the original TEMPLATE_PARM_DECL. gcc/cp/ChangeLog: PR c++/96106 * pt.c (reduce_template_parm_level): Propagate DECL_VIRTUAL_P from the original TEMPLATE_PARM_DECL to the new lowered one. gcc/testsuite/ChangeLog: PR c++/96106 * g++.dg/concepts/abbrev7.C: New test. (cherry picked from commit f31dd9beb95f4beda1d2bd5c0526c42d0ce455c4)
