Unversioned shared library for LLVM libunwind
acquired package info from repodata DB: repodata/0e50863276b0c82d93577659f4645d8d6796dfed61d40c2c5b4d6833adbfc2dc-primary.sqlite.bz2
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).
