--- Comment #1 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Nathaniel Shead <nsh...@gcc.gnu.org>: https://gcc.gnu.org/g:dd9d14f7d53de07beff06004922a2bff20ece671 commit r14-8987-gdd9d14f7d53de07beff06004922a2bff20ece671 Author: Nathaniel Shead <nathanielosh...@gmail.com> Date: Wed Feb 14 12:26:03 2024 +1100 c++: Defer emitting inline variables [PR113708] Inline variables are vague-linkage, and may or may not need to be emitted in any TU that they are part of, similarly to e.g. template instantiations. Currently 'import_export_decl' assumes that inline variables have already been emitted when it comes to end-of-TU processing, and so crashes when importing non-trivially-initialised variables from a module, as they have not yet been finalised. This patch fixes this by ensuring that inline variables are always deferred till end-of-TU processing, unifying the behaviour for module and non-module code. PR c++/113708 gcc/cp/ChangeLog: * decl.cc (make_rtl_for_nonlocal_decl): Defer inline variables. * decl2.cc (import_export_decl): Support inline variables. gcc/testsuite/ChangeLog: * g++.dg/debug/dwarf2/inline-var-1.C: Reference 'a' to ensure it is emitted. * g++.dg/debug/dwarf2/inline-var-3.C: Likewise. * g++.dg/modules/init-7_a.H: New test. * g++.dg/modules/init-7_b.C: New test.
