[cfe-dev] Viewing ASTs

[sskavya]

Hi,

I am trying to view the AST obtained after parsing, in a graphical
representation.
Certain web pages spoke about a command line option '-ast-view' that helps
in viewing 
these through graphviz. However when I use the -ast-view option, the
compiler throws a warning saying

clang: warning: argument unused during compilation: '-ast-view'

Is there anything that I might be missing out? I could not find any notes on
this in the clang manuals.

Thanks,
Kavya
