bool CompilerInstanceWithContext::computeDependencies	(	StringRef	ModuleName,
		dependencies::DependencyConsumer &	Consumer,
		dependencies::DependencyActionController &	Controller )

llvm::Expected< TranslationUnitDeps > CompilerInstanceWithContext::computeDependenciesByNameOrError	(	StringRef	ModuleName,
		const llvm::DenseSet< dependencies::ModuleID > &	AlreadySeen,
		dependencies::LookupModuleOutputCallback	LookupModuleOutput )

Computes the dependeny for the module named ModuleName.

Parameters

ModuleName	The name of the module for which this method computes . dependencies.
AlreadySeen	This stores modules which have previously been reported. Use the same instance for all calls to this function for a single `DependencyScanningTool` in a single build. Note that this parameter is not part of the context because it can be shared across different worker threads and each worker thread may update it.
LookupModuleOutput	This function is called to fill in "-fmodule-file=", "-o" and other output arguments for dependencies.

Returns: An instance of TranslationUnitDeps if the scan is successful. Otherwise it returns an error.

std::optional< CompilerInstanceWithContext > CompilerInstanceWithContext::initializeFromCommandline	(	DependencyScanningTool &	Tool,
		StringRef	CWD,
		ArrayRef< std::string >	CommandLine,
		DiagnosticConsumer &	DC )

static

Initialize the tool's compiler instance from the commandline.

The compiler instance only takes a -cc1 job, so this method builds the -cc1 job from the CommandLine input.

Parameters

Tool	The dependency scanning tool whose compiler instance with context is initialized.
CWD	The current working directory.
CommandLine	This command line may be a driver command or a cc1 command.
DC	A diagnostics consumer to report error if the initialization fails.
