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).
