LGPL-2.1-or-later
* Sun Aug 18 2024 Dirk Müller <dmueller@suse.com>
- update to 0.11.0:
* Identifies git fix id now for ossfuzz 70721
DW202407-010
* Correcting use-after-free with a specific corrupted
DWARF section.
* This simplfies getting correct cooked
addresses for entries from .debug_ranges
* The new code about .debug_ranges had
small leaks when the library was told
not to record or clean-up most memory allocations.
Shown by -fsanitize.
* Fixed a mistake in examplev, .debug_ranges
* Added new argument to print_ranges_list_to_extra()
so it can print both raw and cooked values.
* Now calulates the cooked value of .debug_ranges
and prints both raw and cooked values.
* New date, some Dwarf_Ranges doc has been updated
in libdwarf.
* Added clarifying comment paragraphs about Dwarf_Ranges
* Final on the rnglists ossfuzz issues so far.
* ossfuzz 70246 DW202407-002 fixed.
* Removing esb_append_printf() which is the last use of *sprintf()
* ossfuzz 70244 fixed DW202407-001
* Removing esb_append_printf() as it is no
longer necessary.
* Added blank line after d= semantic version
* Fixed trailing whitespace and indents.
* Refine the information on rnglists base with
* cc_rnglists_base_via_at (similar to loclists)
* Added cc_loclists_base_via_at and
* Due to the addition of dwarf_get_locdesc_entry_e()
we revise the version for the next release to be
* Issue #247, github libdwarf-code.
* Fix indents and eliminate trailing whitespace.
* Corrected the gitfixid as there was
a use-after-free in new-today code, now fixed.
* Fixing a nasty double free that was caused a few
minutes ago.
* New oss fuzz 69639 and 69641 are fixed.
Here identfied as DW202406-001 and DW202406-002
* Remove debug printf (was #if 0 ... #endif)
Fixed DW202406-001 ossfuzz 69639
and
DW202406-002 ossfuzz 69641
* Implemented spelling change ld_kind to ld_lkind
* In dwarf_formref() we correct the reading
of DW_FORM_loclistx and DW_FORM_rnglistx
to read a uleb. Been wrong since 2022 at least..
Another spot reading these had it right all along.
* Renamed ll_kind to ll_lkind as it names a DW_LKIND value
* Renamed ld_kind to ld_lkind as it names a DW_LKIND value
* Revises the dwarfdump reporting of debug_loclists to
clarify the dwarf 5 debug_loclists structure content.
* The --print-raw-loclists option is more useful now.
* Revises the dwarfdump reporting of debug_rnglists to
clarify the dwarf 5 debug_rnglists structure content.
* The --print-raw-rnglists option is more useful now.
* In certain error cases the revised rnglists code
was failing to dwarf_dealloc_error() where
* Updated the output format of --print-raw-loclists
to be more useful and to essentially match the rnglists
version.
* Separated out part of loclists data structs to
be a better match with dwarf_rnglists.h
* Corrected calculations related to rnglists array of
offsets (were calling entries address size when they are offset
size).
* Removed some lines related to merging skeleton and split,
they were wrong. debug_rnglists and debug_rnglists.dwo
* Initialize the three new fields in Dwarf_Debug_s
used for DWARF5 GNU extension .debug_addr printing.
* Renaming DW_DLE_PE_SECTION_SIZE_ERROR
to DW_DLE_PE_SECTION_SIZE_HEURISTIC_FAIL
so any failure of the three such tests are
clearly reported. Should never happen.
* A heuristic sanity check on section VirtualSize
was too concervative at s00MB, a PE object file had a
section over 200MB in size.
* Adding release xz name
* Wed May 29 2024 Dominique Leuenberger <dimstar@opensuse.org>
- Update to version 0.9.2:
+ Fixed four vulnerabilities that could crash the library
(segmentation violation etc) reading specific corruptions to
DWARF.
DW202402-001, DW202402-002,DW202402-003, and DW202403-001.
Now the library returns an error code for those. Corrected a
dwarf.h misspelling of DW_CFA_hi_user.
* Tue Jan 30 2024 Dirk Müller <dmueller@suse.com>
- update to 0.9.1:
* "--disable-decompression" tells the build to compile
libdwarf and dwarfdump with no reference to the zlib or
zstd libraries.
* Latest DW_LANG names now present.
- build with zstd support
* Thu Dec 28 2023 Dirk Müller <dmueller@suse.com>
- update to 0.9.0:
* Added support for reading Apple MacOS universal binaries.
* Added callers access to certain fields from object files
(for all three supported object formats), and
* added the --print-machine-arch option to dwarfdump to show the
fields.
* Three functions were added to the API, see the Changes section
of the latest documentation or in libdwarf.pdf in the release.
No functions were deleted or had their meaning changed.
* Vulnerabilities found by fuzzing were fixed.
* See https://www.prevanders.net/dwarfbug.html for vulnerability
details.
* Sat Nov 18 2023 Dirk Müller <dmueller@suse.com>
- update to 0.8.0:
* The release fixes many vulnerabilities from corrupt DWARF
and/or corrupt Elf. Two new functions are added for DWARF Frame
access to get the correct sign of an argument (the pre-existing
functions remain in place and working avoiding any need for
recompilation or relinking of user code).
* Mon May 29 2023 Dirk Müller <dmueller@suse.com>
- update to 0.7.0:
* The release fixes more than 50 vulnerabilities from corrupt
DWARF and/or corrupt Elf.
* Elf section counts can exceed 16 bits (on linux see man 5 elf)
so some function prototype members of struct
Dwarf_Obj_Access_Methods_a_s changed. Specifically,
om_get_section_info() om_load_section(), and om_relocate_a_section()
now pass section indexes as Dwarf_Unsigned instead of Dwarf_Half.
* Two functions have been removed from libdwarf.h and the library:
dwarf_dnames_abbrev_by_code() and dwarf_dnames_abbrev_form_by_index().
* dwarf_dnames_abbrev_by_code() is slow and pointless. Use either
dwarf_dnames_name() or dwarf_dnames_abbrevtable() instead,
depending on what you want to accomplish.
* dwarf_dnames_abbrev_form_by_index() is not needed, was difficult
to call due to argument list requirements, and never worked.
* Mon Feb 27 2023 Dirk Müller <dmueller@suse.com>
- update to 0.6.0:
Fixes for Denial Of Service (possible libdwarf crash):
* The dealloc required for dwarf_offset_list() was incorrect,
possibly leading to a crash.
* The function prototype for dwarf_dietype_offset() changed so
it can work correctly on DWARF4 objects.
* A memory leak from dwarf_load_loclists() has been fixed.
* The function dwarf_get_pubtypes() changed, Dwarf_Type no longer
exists, correcting a library design mistake made in 1993.
The function applied to DWARF3 and DWARF4 objects.
* The set of functions using Dwarf_Type are gone, use Dwarf_Global
instead. An object with DW_FORM_strx3 (DWARF5) could result in
the library either crashing or returning an inappropriate error.
DW_FORM_strx3 is now handled
* https://newreleases.io/github/davea42/libdwarf-code?version=v0.6.0
* Fri Dec 02 2022 Dirk Müller <dmueller@suse.com>
- update to 0.5.0:
* libdwarf-0.5.0 improves library performance reading
DWARF DIEs by several percent (with no change in API).
* It adds functions allowing acess to the .debug_addr
section independent of other sections.
dwarfdump has a new option to show that
section.
* Corrects the handling of some aspects of
reading the .debug_names section.
* Enhances dwarf_get_globals() to return
all globals that .debug_pubnames and .debug_names
refer to (no change in the API except adding
a function to return the DW_TAG of any globals
derived from .debug_names)
* Mon Oct 03 2022 Dirk Müller <dmueller@suse.com>
- update to 0.4.2:
* memory leak fixes
* How to deal with a dwarf_init*() call
that fails (DW_DLV_ERROR) in a simple way is finally
documented in libdwarf.pdf and in the on-line html.
* Fri Jul 15 2022 Dirk Müller <dmueller@suse.com>
- update to 0.4.1 (bsc#1200899, CVE-2022-34299):
* Two places where a carefully corrupted object file
could result in libdwarf crashing a caller due to
referencing memory outside the intended read area
have been fixed (DW202205-001 and DW202206-001).
One related to DW_FORM_ref_sig8, the other to
the .debug_pubnames section.
* The library now accepts DW_AT_entry_pc in a CU DIE as a base address
when DW_AT_low_pc is missing (an extension used by
a current compiler).
* Added function dwarf_suppress_debuglink_crc() to allow
callers to turn off doing a CRC calculation
reading GNU debuglink data (saves time for library
users accessing near-identical builds).
- drop fix-CVE-2022-32200.patch (upstream)
* Tue Jun 07 2022 Dirk Müller <dmueller@suse.com>
- add fix-CVE-2022-32200.patch (bsc#1200291, CVE-2022-32200)
* Wed Apr 27 2022 Jan Engelhardt <jengelh@inai.de>
- Resolve rpmlint report "libdwarf1.x86_64: E:
shlib-policy-name-error SONAME: libdwarf.so.0, expected package
suffix: 0"
* Sun Apr 24 2022 Dirk Müller <dmueller@suse.com>
- update to 0.4.0:
* Removed the unused Dwarf_Error argument from dwarf_return_empty_pubnames()
as the function can only return DW_DLV_OK. dwarf_xu_header_free() renamed
to dwarf_dealloc_xu_header(). dwarf_gdbindex_free() renamed
to dwarf_dealloc_gdbindex(). dwarf_loc_head_c_dealloc renamed to
dwarf_dealloc_loc_head_c().
* dwarf_get_location_op_value_d() renamed to dwarf_get_location_op_value_c(),
and 3 pointless arguments removed. The dwarf_get_location_op_value_d
version and the three arguments were added for DWARF5 in libdwarf20210528
but the change was a mistake. Now reverted to the previous version.
* The .debug_names section interfaces have changed. Added
dwarf_dnames_offsets() to provide details of facts useful in problems
reading the section. dwarf_dnames_name() now does work
and the interface was changed to make it easier to use.
* Mon Feb 21 2022 Dirk Müller <dmueller@suse.com>
- replace symlink by directory with hardlinks (bsc#1196198)
* Sun Feb 13 2022 Dirk Müller <dmueller@suse.com>
- update to 0.3.3:
* Release fixes a n assign offset = offset;
* Fixes a bug in LEB value reading of some values in the very rare case the
compiler has emitted padding in the LEB
* Has improvements in detecting corrupt object files (Elf, MachO, and PE) and
one new function that is only significant for those using an LLVM feature
for Heterogenous Debugging. Passes Coverity Scan with zero issues.
- drop libdwarf-gcc11.patch, libdwarf-gcc11-fixup.patch: upstream
* Wed Jun 16 2021 Fridrich Strba <fstrba@suse.com>
- Added patch:
* libdwarf-gcc11-fixup.patch
+ fix missing return and double define mistake in the upstream
patch
* Tue Jun 15 2021 Dirk Müller <dmueller@suse.com>
- libdwarf-gcc11.patch: refresh with upstream patch
* Tue Jun 15 2021 Fridrich Strba <fstrba@suse.com>
- Added patch:
* libdwarf-gcc11.patch
+ skip correctly DW_FORM_implicit_const in
_dwarf_formudata_internal (bsc#1187336)
* Fri Jun 11 2021 Fridrich Strba <fstrba@suse.com>
- update to 20210528:
corrects libdwarf's handling of DWARF5 line table header DW_LNCT
entries. Dwarfdump now prints DW_OP_bra and DW_OP_skip correctly
and correctly validates the target of these operators.
adds summary information on attribute/form-class uses and
attribute/forms use to the existing option -ku summary on tags
and attributes. Dwarfdump verifies many attribute references are
usable and prints a little from the target DIE, including with
DW_FORM_ref_sig8 references. Now dwarf.h shows many more
extensions (added by compiler developers) to the TAGs and
ATtributes defines. Alongide releases is a pdf,
libdwarf2.1xl.pdf (xl.pdf as it is extra-large), that is the
same as the latest libdwarf2.1.pdf but with the
table-of-contents at the front, not the back, of the pdf.
Created an experiment, it is around 15MB so seemed too large to
place it in the release or to do multiple versions. Later
updates will just replace it on prevanders.net.
* Wed Apr 21 2021 Wolfgang Frisch <wolfgang.frisch@suse.com>
- Hardening: link as PIE (bsc#1185057).
* Fri Jan 29 2021 Dirk Müller <dmueller@suse.com>
- update to 20201201:
dwarfdump now prints DWARF expression operators each on
its own line. This makes viewing DWARF expressions much
nicer given the increased use of much longer expressions.
Those expression operators that reference DIES are now
followed, verified, and the target DW_TAG and DW_AT_name
are printed. A new dwarfdump.conf command 'option:' lets
one specify option: --format-expr-ops-joined in case you
want the old style DWARF expression operators-on-one-line.
Where the DWARF DIE children nest > nine-deep dwarfdump
switches from indentation by spaces to a nest-level number.
* Mon Oct 26 2020 Dirk Mueller <dmueller@suse.com>
- update to 20201020:
* Fix various read and write outside bounds found via fuzzing
* Fri Sep 04 2020 Dirk Mueller <dmueller@suse.com>
- move libdwarf headers back to the old location
* Wed Sep 02 2020 Dirk Mueller <dmueller@suse.com>
- update to 20200825 (bsc#1142609, CVE-2019-14249)
libdwarf now reads .debug_gnu_pubtypes & pubnames
(non-standard but gcc creates them in DWARF5)
via a small number of new functions
and dwarfdump --print-debug-gnu prints both sections.
Verifying the .debug_info offsets is not yet done.
Dwarfdump now dumps DWARF5 .debug_rnglists and
.debug_loclists. To handle DWARF5 there are
a small number of new functions. All existing
functions are still supported, but
to read DWARF5 some small changes are required.
In libdwarf see libdwarf2.1.pdf and also see
dwarfdump now takes much less malloc() to work, as measured
by valgrind --tool=massif and massif-visualizer.
A dwarfdump run that did 2.2Gib of malloc/free before the changes
now does 1.4GiB.
libdwarf and dwarfdump now support DWARF5 .debug_rnglists.
The new interfaces are documented in libdwarf/libdwarf2.1.pdf.
The new option to dwarfdump is "--print-raw-rnglists".
The code (dwarfdump/libdwarf), regressiontests,
and readelfobj directories and all their tests
are known to work on Linux(Ubuntu on x86_64 and i686),
FreeBSD, MacOS Catalina (with Apple Command Line Tools),
and IBM s390 (Big Endian!) running Ubuntu Linux.
On Windows-MinGW the full regression tests
have not been tested, but 'make check' works
for dwarfdump/libdwarf (the current dwarfdump
make check actually does run dwarfdump and
checks that dwarfdump basically works).
Now a --disable-libelf configure/build of libdwarf/dwarfdump
can read elf, mach-o DSYM, and PE executable/dll object files.
Such a build will not need or use libelf or elf.h .
The dwarfdump options that display Elf section headers
or relocation record data are not available in a
- -disable-libelf build.
Nor is dwarfdump's support of reading archive files
available in a --disable-libelf build.
This libdwarf detects corrupt Elf object files much sooner
than before, but does not explain what the corruption
really is. Use GNU readelf (or readelfobj, a project
on sourceforge) to get more detail about the problems found.
See https://www.prevanders.net/dwarf.html for the git clone
command for readelfobj.
With --disable-libelf the --enable-dwarfgen option
does not work: the dwarfgen build will fail.
For building on machines without a usable elf.h or libelf
but possibly with a libelf.h visible, --disable-libelf
ensures the build won't use libelf or elf.h anywhere.
- lz will be done if zlib.h is visible, independent of
libelf, libelf.h, and elf.h
If one has a standard Bourne shell (sh) available
(such as sh on MacOS and sh in MinGW on Windows)
one may be able to build libdwarf and dwarfdump natively
and they can read Mach-o dSYM and PE object files
to access DWARF information.
This has NOT been tested under MacOS, so will likely
fail on MacOS.
No elf.h, libelf.h or zlib.h should be present.
For example, the following
is known to work under MinGW and this general plan
applies to all builds including all builds with elf.h
and libelf:
mkdir test
cd test
[#](copy the source tree into test, if from git
[#]the name of the top level will likely be 'code')
cd code
The pre-build dwarf_names.[hc] and the tag related
files are now part of the standard build so there is
no longer any two-stage aspect of the build.
The build simply compiles files in the distribution.
If you use git to access the source be sure to
sh scripts/FIX-CONFIGURE-TIMES
to adjust the file timestamps as having timestamps
in the right relationships is vital and git
does not maintain timestamps.
The script is always safe to run. It takes about 30 seconds.
The complicated process of building certain .c and .h
files has been relegated to the few people updating
files libdwarf/libdwarf.h.in, libdwarf/dwarf_errmsg_list.h,
dwarfdump/tag_attr_ext.list,dwarfdump/tag_attr.list,
dwarfdump/tag_tree_ext.list, and dwarfdump/tag_tree.list.
For everyone else the build is simply compiling
the .c and .h files in the distribution. Simpler.
sh scripts/buildstandardsource.sh
creates these files.
dwarfdump can now dump mach-o (MacOS) dSYM dwarf.
All the usual libdwarf interfaces work.
A new libdwarf initialization call dwarf_init_path()
may be convenient for you to use.

* Wed Oct 15 2014 jengelh@inai.de
- Update to new upstream release 20140805
* A mistake in handling DW_OP_GNU_const_type could lead to a
libdwarf coredump at times.
* Added AARCH64 relocation support.
* Adds GNU-specific DW_FORM codes so recent gcc objects can be
read usefully.
* Adds new functions to libdwarf for new DWARF reference types.
* Libdwarf now follows the DWARF2 standard properly in reading
DW_FORM_ref_addr.
* Source incompatibility for users of producer code:
dwarf_producer_init() now has a new interface and a sensible way
to select the output ABI/ISA for relocation numbers. Part of
preparation to emit DWARF3,4,5.
* The reader code now handles DebugFission, called Split Dwarf
objects in the draft DWARF5 standard.
* The reader now can get the content of .gdbindex and
.debug_cu_index and .debug_tu_index sections and dwarfdump -I
can print them. Support is incomplete for the cu,tu sections:
They exist in a .dwp object (GNU Debug Fission, to be in DWARF5)
which is not yet properly handled.
- Enable parallel build and remove ancient specfile tags and sections
* Thu Dec 06 2012 jw@suse.com

* Mon Feb 13 2012 coolo@suse.com
- patch license to follow spdx.org standard
* Sun Sep 19 2010 jengelh@medozas.de
- Update to newer libdwarf (20100808), because the "perf" package
needs a version >= 20100214. Fixes include:
* dwarfdump was counting eh_frame low-pc as a duplicate of
.debug_frame low-pc
* Fixes some CFA_expression handling in libdwarf and allows some
compiler mistakes a bit more leeway in dwarfdump (so the dump
continues in the face of certain errors).
* ARM and MIPS64BE handling
- Stripped changelog from .spec file, since it is already in
.changes.
* Wed Oct 08 2008 dgollub@suse.de
- added libdwarf-dwarf3-dw_attributes.patch:
Allow attribute DW_AT_const_value in dwarf_add_AT_targ_address_b().
GCC generates code which has DW_AT_const_value with DW_FORM_addr.
Additional DWARF3 enhancments:
- allow DW_AT_entry_pc in dwarf_add_AT_targ_address_b()
- allow DW_AT_call_column, DW_AT_call_file, DW_AT_call_line in
dwarf_add_AT_unsigned_const
* Wed Oct 01 2008 dgollub@suse.de
- added libdwarf-relocation-support.patch:
initial ELF relocation support for libdwarf
* Wed Oct 01 2008 dgollub@suse.de
- removed dwarfextract from libdwarf-tools package
(got split into seperated package: dwarfextract)
- reenabled static build of libdwarf
* Fri Aug 22 2008 bwalle@suse.de
- update to 20080818
Minor improvements: dwarfdump print_reloc.c referred to
sym_data_entry_count in one place where sym_data_64_entry_count
should have been tested. DW_DLA_PUBTYPE_CONTEXT was a typo,
DW_DLE_PUBTYPE_CONTEXT was intended. Fixed indentation and
removed some tabs in favor of spaces (in five files). A couple
files had a couple lines with CR-LF line endings, the CR is now
gone. Corrected minor typographical errors in libdwarf2p.1.mm and
libdwarf2.1.mm and regenerated the pdfs.
* Tue Aug 12 2008 bwalle@suse.de
- update dwarfextract: fold dwarf-dwarfextract4.patch into
(from LKCD CVS) libdwarf-add-dwarfextract
* Tue Jun 17 2008 bwalle@suse.de
- update to 20080615
fixed wrong directory name in tarball (20060813 -> 20080815)
* Mon Jun 16 2008 bwalle@suse.de
- update to 20080613
Removed __SGI_FAST_LIBELF code, no one could use it anyway.
Fixed an off-by-one in dwarfdump which could reference off the
end of an array in a specfic circumstance and verify string table
index refers to inside the table when printing relocations.
Corrected return code from libdwarf when there is no dwarf
information. Thanks to Carlos Alberto Enciso for noticing the
bugs. Fixed indentation and removed some tabs in favor of
spaces (in a few files).
* Wed Jun 11 2008 bwalle@suse.de
- update to 20080125
In the producer library code dwarf_die_link() is now O(1) where
it was O(N) before. Thanks to Daniel Gollub for finding this
performance improvement. dwarf_die_link() now back-links siblings
(in its internal lists) correctly. The back link bug had no
(known) effect on dwarf generated by libdwarf.
- update to 20080208
Due to a typo, calling _dwarf_fde_section_offset() (a interface
which is still supported) would lead to an infinite loop in
libdwarf-20071209 and libdwarf-20080125. The libdwarf producer
forms code now allows more of the newer attributes (so is more
complete). Alloca is no longer used anywhere (it was really only
used one place). The libdwarf producer code controlling the
offset-size is more sensible: standard DWARF (32 bit offsets) is
the default, use configure --enable-dwarf-format-sgi-irix to get
IRIX 64bit offsets. See the libdwarf README and libdwarf2p.1.pdf
for details. Thanks to Carlos Alberto Enciso and Melanie Zumwalde
for noticing some of these errors.
- update to 20080228
This changes the libdwarf-internal implementation of reading libelf
so that the reader is not directly tied to libelf or even elf.
Meaning a libdwarf can be built that reads other object file types
or that uses some library other than libelf to do the reading
(subject only to simple constraints, see libdwarf.h). Thanks to
Josh Fuhs for designing and implementing the object-file-reader
revisions.
- update to 20080409
A giant a.out exposed an inflexible (slow) handling of
abbreviations in libdwarf as well as showing that one (internal)
field was too small to accommodate over 64K abbreviations in one
compilation unit. The relevant hash table adapts now and the field
is 'large enough'. Added -H and -n options to dwarfdump. Added a
dwarfdump -ka new check for correctness.
* Fri Jan 25 2008 dgollub@suse.de
- removed README.SUSE, which contained obsolate information about
shared library and versioning.
- update to 20080125
o producer interface:
dwarf_die_link() is now O(1) where it was O(N) before.
* Tue Dec 11 2007 dgollub@suse.de
- building shared lib (instead of static)
- added LD_LIBRARY_PATH to dwarfdump Makefile, since it runs
something within the build which is linked against libdwarf.
- update to 20071209
o Renamed 4 functions so they are now exported by libdwarf as dwarf_*:
dwarf_fde_section_offset(), dwarf_cie_section_offset(),
dwarf_print_lines(), and dwarf_ld_sort_lines() are the new names.
o The old _dwarf_* names are still supported in libdwarf.h but anyone
building a shared library could choose to export only dwarf_* names
and dwarfdump will now compile and link successfully with that shared
library.
o Added acceptance of .eh_frame S augmentation
o Updated config.guess config.sub to latest (2006-11-15)
o Added configure tests and some code in dwarf_incl.h and globals.h
to define _GNU_SOURCE so that it will all compile with recent libelf.h
use of off64_t (yet still compile with earlier libelf.h)
- updated to 20071016
o dwarf_siblingof() could try to access a byte past the
end of an Elf section leading to a coredump.
o The dwarf macro reading code could (in the DWARF_SIMPLE_MALLOC
case only) allocate and free memory inconsistently leading to
malloc arena corruption.
(updated to 20071015)
o The special build macro DWARF_SIMPLE_MALLOC was incorrectly
implemented (now fixed): it could lead builds employing that
macro to coredump in libdwarf. Now (just before exit) dwarfdump
free()s some space it previously left mallocd.
(updated to 20070904)
o Added qualifier for DWARF4 DW_AT_high_pc where applicable in
dwarfdump output.
o Added documentation of new producer functions in libdwarf.
o Misc: Updated FSF address everywhere. Deleted 2 files which
were never used.
* Sat Jul 21 2007 bwalle@suse.de
- add 'dwarfextract' from lkcdutils to libdwarf-tools since
we only distribute 'lcrash' from lkcdutils now
* Sat Jul 21 2007 bwalle@suse.de
- updated to 20070703
o Adding new libdwarf function dwarf_get_loclist_entry() to
extract CFA val_expression bytes usefully.
o dwarfdump now uses that info to print those expression bytes
with -v
o DW_CFA_val_expression was handled wrong in libdwarf leading
eventually to an invalid register number reading a GNU
.eh_frame section (dwarfdump reported an error).
