From 05109b1bd5ef4ee9d78fe17d4563889694a26d05 Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Fri, 8 Mar 2024 09:14:32 +0100 Subject: dwarf2out: Emit DW_AT_export_symbols on anon unions/structs [PR113918] DWARF5 added DW_AT_export_symbols both for use on inline namespaces (where we emit it), but also on anonymous unions/structs (and we didn't emit that attribute there). The following patch fixes it. 2024-03-08 Jakub Jelinek PR debug/113918 gcc/ * dwarf2out.cc (gen_field_die): Emit DW_AT_export_symbols on anonymous unions or structs for -gdwarf-5 or -gno-strict-dwarf. gcc/c/ * c-tree.h (c_type_dwarf_attribute): Declare. * c-objc-common.h (LANG_HOOKS_TYPE_DWARF_ATTRIBUTE): Redefine. * c-objc-common.cc: Include dwarf2.h.
