Functions
bool	clang::scanSourceForDependencyDirectives (StringRef Input, SmallVectorImpl< dependency_directives_scan::Token > &Tokens, SmallVectorImpl< dependency_directives_scan::Directive > &Directives, DiagnosticsEngine *Diags=nullptr, SourceLocation InputSourceLoc=SourceLocation())
	Scan the input for the preprocessor directives that might have an effect on the dependencies for a compilation unit.
void	clang::printDependencyDirectivesAsSource (StringRef Source, ArrayRef< dependency_directives_scan::Directive > Directives, llvm::raw_ostream &OS)

bool	clang::scanInputForCXX20ModulesUsage (StringRef Source)
	Scan an input source buffer for C++20 named module usage.

Detailed Description

This is the interface for scanning header and source files to get the minimum necessary preprocessor directives for evaluating includes.

It reduces the source down to #define, #include, #import, @import, and any conditional preprocessor logic that contains one of those.
