[cfe-dev] Using clang for source to source transformations

[Nathan Lawrence]

Hi,

I'm trying to use clang as a source-to-source transformer to reorder
statements in c code.  It is not necessary maintain formatting.

I've been looking through the documentation, but I can't find an
obvious way to do this.  I would like to be able to operate on an AST
and not a token stream.

How would you recommend doing this?

Thanks,
-- Nathan
