[cfe-dev] Extracting preprocessor documentation

[Guilherme]

Hello,

Currently (my version is 3.4.2) when dumping the ast with -ast-dump i
can see that comments that represent documentation is kept in the AST.

Unfortunately it seems that preprocessor defines are not so lucky.  Is
there any command line option that will allow me to keep the
preprocessor tokens with their documentation? Has this been
implemented in a newer clang version?

Thank you very much
