--- Comment #4 from Mark Wielaard <mark at gcc dot gnu.org> ---
The following bugs might be added to this meta-bug. But they seemed not very
urgent because they involve non-default -g/-f debug flags:

- -flto -g -gsplit-dwarf is broken
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D88389

- .debug_pubnames/types empty with -flto
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D88878

- -g -flto -fdebug-types-section is broken for units with over 64k types
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D93117

- exception and unwind state is not carried to LTO but controls
  EH vs debug frame
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D91794

- ICE with '-flto -g -femit-struct-debug-baseonly'
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D93951

There is also:
- LTO produces line info entries with invalid line numbers
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D94311
But that seems to have been reduced to a variant of:
- debug_line with LTO refers to bogus file-names
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D93865
(Which already blocks this bug)=
