The IOSSIM code from llvm's sanitizer was never migrated into gcc so that would be a red herring. The underlying issue is that the /usr/lib/system/libdyld.dylib required for the current code to work was only introduced in 10.7 (darwin11). So a test for the target being darwin10 or earlier would be the appropriate test for utilizing the legacy code.
