CPP: Missing code in database

When I compile some projects, I use `configure` and `make `to create a database.
But some code in `#if `or `#ifdef`. Maybe there are conditions that need to be met for this to be compiled? So when I query for a functioncall that in source code, the result maybe none.
Is there some log info can let me know which part in a file is compiled?
For example, the file in the attachment, when I search for ASN1_STRING_to_UTF8, the result is none.
