+
+LLVM libunwind is an implementation of the interface defined by the HP libunwind
+project. It was contributed Apple as a way to enable clang++ to port to
+platforms that do not have a system unwinder. It is intended to be a small and
+fast implementation of the ABI, leaving off some features of HP's libunwind
+that never materialized (e.g. remote unwinding).
