--- Comment #21 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-9 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:ef5db37cc4e80b229502bea7d6e2daa95ad6f805 commit r9-9412-gef5db37cc4e80b229502bea7d6e2daa95ad6f805 Author: Jakub Jelinek <ja...@redhat.com> Date: Thu Jan 28 16:13:11 2021 +0100 c++: Fix up handling of register ... asm ("...") vars in templates [PR33661, PR98847] As the testcase shows, for vars appearing in templates, we don't attach the asm spec string to the pattern decls, nor pass it back to cp_finish_decl during instantiation. The following patch does that. 2021-01-28 Jakub Jelinek <ja...@redhat.com> PR c++/33661 PR c++/98847 * decl.c (cp_finish_decl): For register vars with asmspec in templates call set_user_assembler_name and set DECL_HARD_REGISTER. * pt.c (tsubst_expr): When instantiating DECL_HARD_REGISTER vars, pass asmspec_tree to cp_finish_decl. * g++.target/i386/pr98847.C: New test.
