- The MacToolChain will emit dSYMs and strip executables when the UBT configuration enables bGeneratedSYMFile, just like iOS.
- Symbol stripping requires generating dSYMs to prevent creation of non-debuggable builds whose crash reports would be unresolvable.
- To avoid a dependency on the Private framework CoreSymbolication all symbols from that framework are loaded dynamically & can only be used within programs, not the game or the editor, as CoreSymbolication is incompatible with non-ANSI malloc implementations.
- Added an initial platform-agnostic API for querying debug symbol info, including a generic database format that can be queried on otherwise incompatible platforms.
- Added UnrealAtoS that emulates Apple's atos to resolve symbols using the generic database or the platform API (CoreSymbolication on OS X) which on OS X is used by the editor to gather symbol info for CodeView.
- Added DSymExporter which will export Apple debug symbol data from Mach-O binaries, including the payload within a .dSYM bundle, to the generic format so that the crash report server may one day read the data without needing a Mac to symbolicate reports.
- Initial SymbolDebugger & MinidumpDiagnostics support on OS X.
