--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:6384e940a6db379b0524465cf6cbbd0996b48485 commit r11-8431-g6384e940a6db379b0524465cf6cbbd0996b48485 Author: Jason Merrill <ja...@redhat.com> Date: Tue May 18 12:06:36 2021 -0400 c++: "perfect" implicitly deleted move [PR100644] Here we were ignoring the template constructor because the implicit move constructor had all perfect conversions. But CWG1402 says that an implicitly deleted move constructor is ignored by overload resolution; we implement that instead by preferring any other candidate in joust, to get better diagnostics, but that means we need to handle that case here as well. gcc/cp/ChangeLog: PR c++/100644 * call.c (perfect_candidate_p): An implicitly deleted move is not perfect. gcc/testsuite/ChangeLog: * g++.dg/cpp0x/implicit-delete1.C: New test.
