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

[Peeter Joot]

I've answered part of my own question, by grepping the clang source tree
for ArrayTypeLoc, and found I can do something like:

      TypeLoc TL = t->getTypeLoc() ;

      // don't care if it's an array, just want the basic underlying type
of the array.
      if ( const ArrayTypeLoc *Arr = dyn_cast<ArrayTypeLoc>(&TL) )
      {
         TL = Arr->getElementLoc() ;
      }

Am guessing I can probably do something similar to see if the type is a
pointer or reference.

Is there any easy way to determine if the underlying type is one of the
fundamental types: char, short, int, long (not caring about
sign/const/volatile/... variations of these)?
