matcher openmp directive

Hi there:

i try to match an openmp directive using AST Matcher, but i can not make it.

for example:


#pragma omp parallel



how to match this node?

this node should be a STMT in AST, i can see this in RecursiveASTVisitor.h :
{ TRY_TO(TraverseOMPExecutableDirective(S)); })

so how to narrow down the stmt() matcher to get this node?
