Historically this was called 'compiler-rt' informally, but perhaps better called 'libclang_rt', which provides the core necessary runtime library facilities to compile C or C++ applications. It's analogous to libgcc but without some of the unwinding code (as I understand it, there may be details I'm wrong about here or glossing over, but it's not relevant to the organization of things).

For some reason, the (generic, language-agnostic) unwind code is in libcxxabi.  There was some discussion about moving it into the compiler-rt repository, where it would make sense.  No one objected, but I'd rather not move it without a 'yes' from someone who is actually working on the code currently (I'd like to start factoring out the #ifdefs into a cleaner platform / architecture layer).

On FreeBSD, the 'libgcc' that we ship is now mostly code from the compiler-rt repository and it would be nice to have libgcc_s from the same source.
