--- Comment #2 from Michael Matz <matz at gcc dot gnu.org> 2011-03-01 17:06:42 UTC ---
Due to the definition of dwarf2/3 these offsets are negative on little-endian
machines.  This was fixed in dwarf4, see
  http://dwarfstd.org/ShowIssue.php?issue=081130.1&type=closed3

GCC doesn't yet support this part of dwarf4.  But even for dwarf2 we could
emit this signed number as sleb128, not as unsigned number (that is what
causes us to use FORM_data8).
