    The Application Binary Interface, or ABI for short, is intended to provide certain low level functions from which to build the C++ standard library. It is a supporting library that is a separate component from the actual standard library. Along with libcxxabi, you may also come across Pathscale's libcxxrt or GCC's libsupcxx.

    On the other hand, libc++ is an implementation of the C++ standard library that can be built using either of the 3 mentioned ABIs.
