            Bug ID: 24344
           Summary: [dwz] Support relocatable elf
           Product: dwz
           Version: unspecified
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: default
          Assignee: nobody at sourceware dot org

  Target Milestone: ---

When building openSUSE:Factory/kernel-vanilla I get lots of "is not a shared
library" errors, like f.i.:
...
[ 3916s] dwz:
"./lib/modules/4.20.13-0-vanilla/kernel/sound/usb/6fire/snd-usb-6fire.ko.de=
bug"
is not a shared library
...

This is a file with debug info for a loadable module, which is an ELF
relocatable:
...
$ file
./usr/lib/debug/lib/modules/4.20.13-0-vanilla/kernel/sound/usb/6fire/snd-us=
b-6fire.ko.debug
./usr/lib/debug/lib/modules/4.20.13-0-vanilla/kernel/sound/usb/6fire/snd-us=
b-6fire.ko.debug:
ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV),
BuildID[sha1]=3D5f01e04c17fe8b2f9941b0981ff89ebbe3eb308e, with debug_info, =
not
stripped
...

Dwz doesn't support relocatables atm. To do so, it would have to add suppor=
t to
parse and update RELA section related to debug sections.

Not sure if this feature would be useful for anything else than loadable
modules.
