Static analysis of C code including preprocessor statements? [message #109266]

Hi All,

I am developing static analysis tools for C using the CDT parser. I have
the following problem:

Example:
#if 0
i++;
#endif

How can I get a parse tree for the "i++;" statement? The parser detects
that this statement is unreachable, but I need to cover all C code (when
checking coding styles etc.).

Has anybody solved this problem?

Cheers,

Hendrik

We use CDT to parse the code. Currently there are a few limitations with
CDT's parser which impact the ability tp parse into code inside compiler
directives. We are trying to resolve this with the CDT team but it's going
to take some time.
