--- Comment #8 from Thomas Schwinge <tschwinge at sourceware dot org> ---
So I wanted to use libabigail on GCC '-gsplit-dwarf' object files
('*.o'/'*.dwo'), and found that it doesn't work.  Then found this existing PR;
confirming that status is still as per Andrew's 2018-06-16 comment:
'eu-readelf'/elfutils (Ubuntu 0.176-1.1build1 in my case) appears to work, but
'abidw'/libabigail (current master branch) doesn't even open the '*.dwo' file,
per 'strace'.

If I wanted to try help implement that (but no promises how far I'll get...),
are Mark's 2018-06-05 comments here re "libabigail will need to use a few new
interfaces" still applicable, to get started?

Additionally, in PR25042 I saw Mark's 2019-09-30 comment that "logic [there] is
broken, [...] when dealing with split-dwarf DWO files", so I suppose that needs
to be reworked, too?  Per Dodji's 2019-10-01 comment, "this optimization will
be unnecessary, hopefully".
