--- Comment #2 from Mark Wielaard <mark at klomp dot org> ---
This probably is something that elfutils should transparently support for
libabigail. But currently elfutils libdw doesn't support GNU DebugFission
dwp/split-dwarf. Parts of it are in the process of being standardized now for
DWARF5. But the standard hasn't been finalized and code for elfutils is not yet
there (and after DWARF5 public beta was released some details were changed).

For now I would recommend not using -gsplit-dwarf and dwp. If you are looking
for smaller or "split" DWARF then yse using eu-strip -o and dwz to create debug
multi-files. That is supported.
