--- Comment #3 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:dab932d1519ba07fb4c49e6849ee7ceb02c0d603 commit r10-7394-gdab932d1519ba07fb4c49e6849ee7ceb02c0d603 Author: Jakub Jelinek <ja...@redhat.com> Date: Thu Mar 26 09:31:15 2020 +0100 c++: Fix up user_provided_p [PR81349] The standard says: "A function is user-provided if it is user-declared and not explicitly defaulted or deleted on its first declaration." I don't see anything about function templates having different rules here, but user_provided_p does return true for all TEMPLATE_DECLs. The following patch fixes it by treating as user-provided only templates that aren't deleted. 2020-03-26 Jakub Jelinek <ja...@redhat.com> PR c++/81349 * class.c (user_provided_p): Use STRIP_TEMPLATE instead of returning true for all TEMPLATE_DECLs. * g++.dg/cpp1z/pr81349.C: New test.
