Detailed Description

Preprocessor tracker for modularize.

The PreprocessorTracker class defines an API for checking macro expansions and preprocessor conditional expressions in a header file for consistency among one or more compilations of the header in a #include scenario. This is for helping a user find which macro expansions or conditionals might be problematic with respect to using the headers in the modules scenario, because they evaluate to different values depending on how or where a header is included.

The handlePreprocessorEntry function implementation will register a PPCallbacks object in the given Preprocessor object. The calls to the callbacks will collect information about the macro expansions and preprocessor conditionals encountered, for later analysis and reporting of inconsistencies between runs performed by calls to the reportInconsistentMacros and reportInconsistentConditionals functions respectively. The handlePreprocessorExit informs the implementation that a preprocessing session is complete, allowing it to do any needed compilation completion activities in the checker.
