I've been thinking about creating this documentation and haven't done so yet.  The precise specification, while largely nailed down, still has 1 or 2 degrees of freedom that haven't been set in concrete.

It does include the unwinding library and follows the Itanium C++ ABI (http://www.codesourcery.com/public/cxx-abi/abi-eh.html).
