--- Comment #1 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Nathan Sidwell <nat...@gcc.gnu.org>: https://gcc.gnu.org/g:8c4f0c0ceb346e7deb69a44688faab6103aa57da commit r11-7477-g8c4f0c0ceb346e7deb69a44688faab6103aa57da Author: Nathan Sidwell <nat...@acm.org> Date: Fri Feb 26 07:51:13 2021 -0800 c++: namespace reachability [PR 99344] This reworks namespace serializing to avoid some issues I ran into when working on 99170. In modules, (non-anonymous) namespaces are strange beasts, that always have external linkage, but may have module-specific visibility. I still don't get the latter 100% correct, but this is in the right direction. PR c++/99344 gcc/cp/ * module.cc (trees_out::decl_node): Small refactor. (depset::hash::add_binding_entity): Return true on meeting an import. Set namespace's import here. (module_state:write_namespaces): Inform of purview too. (module_state:read_namespaces): Adjust. * name-lookup.c (implicitly_export_namespace): Delete. (do_pushdecl): Don't call it. (push_namespace): Likewise, set purview. (add_imported_namespace): Reorder parms. * name-lookup.h (add_imported_namespace): Alter param ordering. gcc/testsuite/ * g++.dg/modules/namespace-2_a.C * g++.dg/modules/pr99344_a.C * g++.dg/modules/pr99344_b.C
