Can clang be told not to analyze certain files?

Question

I'm trying to use clang to profile a project I'm working on. The project includes a rather large static library that is included in Xcode as a dependency.

I would really like clang to not analyze the dependencies' files, as it seems to make clang fail. Is this possible? I've been reading the clang documentation, and I haven't found it.

Answer 1

As a last resort, there is a brute force option.

Add this to the beginning of a file:

// Omit from static analysis. #ifndef __clang_analyzer__ 

Add this to the end:

#endif // not __clang_analyzer__ 

and clang --analyze won't see the contents of the file.

Answer 2

So, this isn't really an answer, but it worked well enough.

What I ended up doing was building the static library ahead of time, and then building the project using scan-build. Since there was already an up-to-date build of the static library, it wasn't rebuilt and thus wasn't scanned.

I'd still love to have a real answer for this, though.
