Override this to disable registering matchers and PP callbacks if an invalid language version is being used.
For example if a check is examining overloaded functions then this should be overridden to return false when the CPlusPlus flag is not set in LangOpts
.

overridevirtual |
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:

Should store all options supported by this check with their current values or default values for options that haven't been overridden.
The check should use Options.store()
to store each option it supports whether it has the default value or it has been overridden.

A variadic macro is function-like at the same time. Therefore variadic macros are checked first and will be excluded for the function-like diagnostic.
