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)
	Print the previously scanned dependency directives as minimized source text.
bool	clang::scanInputForCXX20ModulesUsage (StringRef Source)
	Scan an input source buffer for C++20 named module usage.
bool	clang::isPreprocessedModuleFile (StringRef Source)
	Scan an input source buffer, and check whether the input source is a preprocessed output.

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.
