--- Comment #1 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Patrick Palka <ppa...@gcc.gnu.org>: https://gcc.gnu.org/g:2e2e65a46d2674bed53afd211493876ee2b79453 commit r12-3585-g2e2e65a46d2674bed53afd211493876ee2b79453 Author: Patrick Palka <ppa...@redhat.com> Date: Thu Sep 16 15:03:55 2021 -0400 c++: constrained variable template issues [PR98486] This fixes some issues with constrained variable templates: - Constraints aren't checked when explicitly specializing a variable template. - Constraints aren't attached to a static data member template at parse time. - Constraints don't get propagated when (partially) instantiating a static data member template, so we need to make sure to look up constraints using the most general template during satisfaction. PR c++/98486 gcc/cp/ChangeLog: * constraint.cc (get_normalized_constraints_from_decl): Always look up constraints using the most general template. * decl.c (grokdeclarator): Set constraints on a static data member template. * pt.c (determine_specialization): Check constraints on a variable template. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/concepts-var-templ1.C: New test. * g++.dg/cpp2a/concepts-var-templ1a.C: New test. * g++.dg/cpp2a/concepts-var-templ1b.C: New test.
