            Bug ID: 24725
           Summary: [dwz] Support compressed debug sections
           Product: dwz
           Version: unspecified
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: default
          Assignee: nobody at sourceware dot org
          Reporter: vries at gcc dot gnu.org
                CC: dwz at sourceware dot org
  Target Milestone: ---

Atm we error out when encountering a zlib-compressed debug section:
...
            if (dso->shdr[i].sh_flags & SHF_COMPRESSED)
              {
                error (0, 0,
                       "%s: Found compressed %s section, not attempting dwz"
                       " compression",
                       dso->filename, name);
                return 1;
              }
...

We could support this by zlib-decompressing before and zlib-recompressing a=
fter
dwz-compression.
