[Bug c++/96106] [10/11 Regression] A friend abbreviated template function denies access to private members
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96106 --- Comment #4 from CVS Commits --- The releases/gcc-10 branch has been updated by Patrick Palka : https://gcc.gnu.org/g:745ba1024c653324f9f0b88968c6f8989ed1e093 commit r10-8604-g745ba1024c653324f9f0b88968c6f8989ed1e093 Author: Patrick Palka 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.
