Breakpad Linux Dumper: submit DWARF-on-Linux
I have a patch series that adds DWARF support to the Breakpad Linux dumper; the patch series is published at: http://hg.mozilla.org/users/jblandy_mozilla.com/breakpad-mq/ The patched dumper produces plausible output. However, it has not yet been submitted to the Breakpad project because it hasn't been given a thorough testing. This testing would include, at the least, compiling the same program with STABS and DWARF, dumping each, and comparing the output. Ideally, it would include tests that provide complete source-code coverage of the dumper.
This now has a pretty thorough suite of unit tests, and has been submitted to Google for review. Patches and work are in the Breakpad issue database, with URLs like: http://breakpad.appspot.com/51004/show 51004 - Linux Breakpad Dumper: support running unit tests under valgrind or other wrapper programs. 50002 - Breakpad DWARF Reader: Also look for DWARF in sections with the proper names. 50004 - Breakpad DWARF Reader: Change LineInfoHandler::AddLine to provide the line's length. 49009 - Breakpad DWARF Parser: Improved DWARF-processing interface. 50005 - Breakpad Linux Dumper: Add DWARF support. 49006 - Google Breakpad DWARF reader: Add a handler function for DIE references. 50003 - Breakpad DWARF Reader: Add DWARF language enumeration values.
All patches approved by Google, but the last one has one comment pending. Weekend!!
All patches landed. Google Breakpad now supports the DWARF debugging format on Linux.
