- Implementation of PowerPC stackwalker. Tested using stackwalker_selftest (#18). - Hook up processor-side multi-CPU support in MinidumpProcessor and minidump_stackwalk using the new Stackwalker::StackwalkerForCPU method. http://groups.google.com/group/airbag-dev/browse_thread/thread/1c2fa7c5182a77a9 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@34 4c0a9323-5329-0410-9bdc-e9ce6186880e
