[cfe-dev] getting info about fields in a RecursiveASTVisitor::VisitFieldDecl override

[Peeter Joot]

I've got an AST visitor override for class members:

   bool VisitFieldDecl( FieldDecl * f )
   {
      RecordDecl * r = f->getParent() ;
      cout << "CLASS: " << r->getName().str() << endl ;
      cout << "MEMBER: " << f->getName().str() << " ( " ;

      TypeSourceInfo * t = f->getTypeSourceInfo() ;

      TypeLoc TL = t->getTypeLoc() ;

      const QualType & q = TL.getType() ;

      cout << "TYPE: " << q.getAsString() << " )" << endl ;

      return true ;
   }

I'd like to be able to check a few things about the types of the
class/struct/union members that this finds:

- ask if q is a basic type (pointer, reference, char, short, int, ...)?
- if q is an array type, what's the underlying array type?

(motivation: I'd like to know what all the true dependencies of a given
struct is, with an eventual goal of comparing the header file dependencies
to the actual structure dependencies ... ignoring for now dependencies that
are introduced by inline member functions).
