Active development happens in Intel's tree, and is slowly being merged = upstream. Eventually, Clang will have full OpenMP 4 support, but = Intel's tree will have it first and there is likely to be a lag before = it makes it into mainline clang. As such, it would make sense to have a port as a stop-gap until it is = ready. David
