Member Function Documentation

◆ registerPPCallbacks()

void clang::tidy::llvm_check::IncludeOrderCheck::registerPPCallbacks ( const SourceManager &  SM,
Preprocessor *  PP,
Preprocessor *  ModuleExpanderPP 

Override this to register PPCallbacks in the preprocessor.

This should be used for clang-tidy checks that analyze preprocessor- dependent properties, e.g. include directives and macro definitions.

This will only be executed if the function isLanguageVersionSupported returns true.

There are two Preprocessors to choose from that differ in how they handle modular #includes:

  • PP is the real Preprocessor. It doesn't walk into modular #includes and thus doesn't generate PPCallbacks for their contents.
  • ModuleExpanderPP preprocesses the whole translation unit in the non-modular mode, which allows it to generate PPCallbacks not only for the main file and textual headers, but also for all transitively included modular headers when the analysis runs with modules enabled. When modules are not enabled ModuleExpanderPP just points to the real preprocessor.

Reimplemented from clang::tidy::ClangTidyCheck.
