--- Comment #2 from Konstantin Tokarev <annulen at yandex dot ru> ---
Thanks, I didn't think about that way somehow. However, I still think there=
 is
a room for usability improvement.

I think following way would be the most convenient:=20
1) we run dwz on "main" ELF files instead of extracted debug info
2) if .debug_info section is missing dwz optimizes file referenced in
.gnu_debuglink and updates CRC
3) if input file looks like "debug file", i.e. file produced by objcopy
--only-keep-debug, print a suggestion that dwz might need to be run on "mai=
n"
file or CRC will be off

In this workflow it would also be possible to use multifile mode without mu=
ch
hassle.
