--- 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:edbb2551d156d69a2e337dcd8daa69f2680d57ea commit r13-3163-gedbb2551d156d69a2e337dcd8daa69f2680d57ea Author: Patrick Palka <ppa...@redhat.com> Date: Fri Oct 7 09:32:45 2022 -0400 c++ modules: static var in inline function [PR104433] The below testcase fails to link with the error undefined reference to `f()::y' ultimately because during stream out for the static VAR_DECL y we override DECL_EXTERNAL to true, which later during IPA confuses symbol_table::remove_unreachable_nodes into thinking it's safe to not emit the symbol. The streaming code here already avoids overriding DECL_EXTERNAL for inline vars and functions, so it seems natural to extend this to static vars from an inline function. PR c++/104433 gcc/cp/ChangeLog: * module.cc (trees_out::core_bools): Don't override DECL_EXTERNAL to true for static variables from an inline function. gcc/testsuite/ChangeLog: * g++.dg/modules/static-2_a.H: New test. * g++.dg/modules/static-2_b.C: New test.
