--- Comment #6 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:099a66498bf7a40764002793eba66c881a251b76 commit r13-2878-g099a66498bf7a40764002793eba66c881a251b76 Author: Patrick Palka <ppa...@redhat.com> Date: Mon Sep 26 11:30:17 2022 -0400 c++ modules: variable template partial spec fixes [PR107033] In r13-2775-g32d8123cd6ce87 I missed that we need to adjust the call to add_mergeable_specialization in the MK_partial case to correctly handle variable template partial specializations (it currently assumes we're always dealing with one for a class template). This fixes an ICE when converting the testcase from that commit to use an importable header instead of a named module. PR c++/107033 gcc/cp/ChangeLog: * module.cc (trees_in::decl_value): In the MK_partial case for a variable template partial specialization, pass decl_p=true to add_mergeable_specialization, and set spec to the VAR_DECL not the TEMPLATE_DECL. * pt.cc (add_mergeable_specialization): For a variable template partial specialization, set the TREE_TYPE of the new DECL_TEMPLATE_SPECIALIZATIONS node to the TREE_TYPE of the VAR_DECL not the VAR_DECL itself. gcc/testsuite/ChangeLog: * g++.dg/modules/partial-2.cc, g++.dg/modules/partial-2.h: New files, factored out from ... * g++.dg/modules/partial-2_a.C, g++.dg/modules/partial-2_b.C: ... these. * g++.dg/modules/partial-2_c.H: New test. * g++.dg/modules/partial-2_d.C: New test.
