This patch rewrites the Mac symbol dumper to use the same set of classes the Linux dumper does for reading debugging information from various sources, consolidating them into a single table, and writing that out as a Breakpad symbol file. In the process, it also adds support for dumping DWARF call frame information and .eh_frame exception-handling information as Breakpad 'STACK CFI' records. This allows the Breakpad processor to generate stack traces from code compiled with -fomit-frame-pointer. The patch also replaces the DumpSymbols Objective C++ class with google_breakpad::DumpSymbols, a plain C++ class. The code still uses some Objective C++ to use the Foundation facilities for dealing with file names in a file-system-independent fashion, and for examining the contents of .dSYM bundles. Since the code has been entirely rewritten, I have changed the author lines. A=jimb R=mark git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@614 4c0a9323-5329-0410-9bdc-e9ce6186880e
