llvm-gcc has some support for OpenMP via the atomic built-ins.  It's largely untested. I ran the tests a few days ago to test something, but that's about it - and has some bugs.  clang does not currently have support for OpenMP.

You would use the llvm-gcc support the same way you would the gcc support.
