Bug ID: 78628
Summary: GO fails to build a translation unit decl
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Keywords: wrong-debug
Severity: normal
Priority: P3
Component: go
Assignee: ian at airs dot com
Reporter: rguenth at gcc dot gnu.org
CC: cmang at google dot com
Target Milestone: ---
The GO FE does not build a TRANSLATION_UNIT_DECL which both LTO and dwarf2out
(debug_hooks->register_main_translation_unit) take information from like the
language of the source.
Frontends nowadays are expected to preferably use a TRANSLATION_UNIT_DECL
as DECL_CONTEXT for file-scope entities (rather than NULL_TREE) and LTO
requires at least one TU DECL to fixup such NULL_TREE file-scope DECL_CONTEXT.
