Description Mamoru TASAKA 2009-06-13 17:36:55 UTC
Description of problem:
After gcc-4.4.0-8 change:
* Fri Jun 12 2009 Jakub Jelinek <jakub> 4.4.0-8 
- update from gcc-4_4-branch 
  - PRs c++/40381, libfortran/40330 
- add -mcrc32 support on ix86 
- support -gdwarf-3 and default to it, emit DW_OP_call_frame_cfa 
- fix up ix86 padding for branch mispredicts 
- improve .debug_loc generation 
rpm cannot create debuginfo rpm correctly.

For example:
i586 build log says:
+ /usr/lib/rpm/find-debuginfo.sh --strict-build-id /builddir/build/BUILD/jd-2.4.1-svn2883_trunk
extracting debug info from /builddir/build/BUILDROOT/jd-2.4.1-0.1.svn2883_trunk.fc12.i386/usr/bin/jd
/usr/lib/rpm/debugedit: /builddir/build/BUILDROOT/jd-2.4.1-0.1.svn2883_trunk.fc12.i386/usr/bin/jd: Unknown debugging section .debug_pubtypes
/usr/lib/rpm/debugedit: /builddir/build/BUILDROOT/jd-2.4.1-0.1.svn2883_trunk.fc12.i386/usr/bin/jd: DWARF version 3 unhandled
+ /usr/lib/rpm/check-buildroot
and the created debuginfo rpm
does not have any debug information.

Version-Release number of selected component (if applicable):

How reproducible:

Comment 1 Jakub Jelinek 2009-06-13 18:03:43 UTC
I'm working on a prelink patch to handle all the recent DWARF3 stuff, and as debugedit is based on prelink's dwarf2 adjustment code, I guess most of it will apply to debugedit as well.

So far only lightly tested prelink patch.  debugedit.c needs similar changes.

Comment 3 Jakub Jelinek 2009-06-13 20:24:42 UTC

Totally untested debugedit.c patch.

Comment 4 Ville Skyttä 2009-06-15 15:28:07 UTC
Would be nice to have this fixed as soon as possible to avoid mass rebuilds due to broken debuginfos and to make it easier to track ones that are results of packaging bugs...

Comment 5 Panu Matilainen 2009-06-16 11:47:30 UTC
Jakub's patch from comment #3 now built into rpm-4.7.0-7.fc12 (and applied upstream too) so this should be fixed as soon as the new version hits the builders.
