[cfe-dev] Extracting preprocessor documentation

[Guilherme]

Well i thought this would be the answer i would get.

Is it possible to do this from a theoretical point of view? The
problem i see is that preprocessing is done in stage 4 where there is
no syntax tree. It is built in stage 7.

Would there still be a way to annotate this in the syntax tree?

Thank you
