- PDBSourceLineWriter (dump_syms) outputs stack frame debugging information - SourceLineResolver reads the new information and puts it into a new StackFrameInfo structure, which is stored in a ContainedRangeMap. FillSourceLineInfo passes the StackFrameInfo back to the caller. - The base Stackwalker makes StackFrameInfo data available to subclasses during stackwalking, but does not use this information directly itself. Stackwalkers may access stack_frame_info_ for enhanced stackwalking (this will be part 4). - New test data for the updated dumped-symbol format http://groups.google.com/group/airbag-dev/browse_thread/thread/735f191c9a1a1de4 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@38 4c0a9323-5329-0410-9bdc-e9ce6186880e
