[cfe-dev] Clang does not rewrite expressions with NULL

[Andrey Tarasevich]

Thank you for the answer.

So there is no easy way to rewrite Stmt that have macros defined in
different files. I'll have to write my own functions for calculating
the length of the expression and combine them with
Rewriter.ReplaceText()? Well this is how I did it at the moment, I'm
just curioгs if there are other ways.
