Liviu Nicoara commented on STDCXX-1067:
---------------------------------------
The default, LLVM-based, C++ compiler shipped by Apple does not come with a C++
support library. Instead, Apple folds (almost) all C++ support in libc++, an
implementation of the C++ Standard library, leaving only a small layer outside,
in the form of libc++abi, in order to facilitate the portability of the C++
Standard Library.
Pathscale produces and released libcxxrt, based on libc++abi, which adds the
missing C++ support to libc++abi, effectively replacing gcc's libsupc++.
