title: representation of C++ by clang
body: <p>I would like to know which classes clang uses to represent C++(not C) source information</p>
  
  <p>I need the internal representation ,that can be useful in the DWARF(<a href="http://en.wikipedia.org/wiki/DWARF" rel="nofollow" title="DWARF">http://en.wikipedia.org/wiki/DWARF</a>) .For example for the type the relevant info could be :size in bytes of this type,byte alignment of this type etc</p>
  
  <p>I have downloaded LLVM + Clang.
  I have looked at <a href="http://clang.llvm.org/docs/InternalsManual.html" rel="nofollow">http://clang.llvm.org/docs/InternalsManual.html</a> but didn't found my answer so
  could someone direct me maybe I missed something and tell  me in which classes I have to start looking for this data? </p>
