If any of it were dropped, or things became otherwise inconsistent, because of the cross-referencing, it would be possible to detect the problem and drop the entire parallel region. The problem with using this for OpenMP is that there are cases where dropping the entire parallel region is not a valid thing to do.

In another compiler that I know, the OpenMP directives were processed 
very early, before any other transformation that could have damaged them.
