From: "matz at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug debug/47946] Dwarf uses 64-bits to refer to a structure offset unnecessarily Date: Tue, 01 Mar 2011 17:07:00 -0000 [thread overview] Message-ID: <bug-47946-4-tRfNuLscH7@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-47946-4@http.gcc.gnu.org/bugzilla/> http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47946 Michael Matz <matz at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |matz at gcc dot gnu.org --- 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).
