Detailed Description

An individual dependency scanning worker that is able to run on its own thread.

The worker computes the dependencies for the input files by preprocessing sources either using a fast mode where the source files are minimized, or using the regular processing run.

◆ computeDependencies() [1/2]

bool DependencyScanningWorker::computeDependencies	(	StringRef	WorkingDirectory,
		ArrayRef< ArrayRef< std::string > >	CommandLines,
		DependencyConsumer &	DepConsumer,
		DependencyActionController &	Controller,
		DiagnosticConsumer &	DiagConsumer,
		llvm::IntrusiveRefCntPtr< llvm::vfs::OverlayFileSystem >	OverlayFS = nullptr )

Run the dependency scanning tool for all given frontend command-lines, and report the discovered dependencies to the provided consumer.

OverlayFS should be based on the Worker's dependency scanning file-system and can be used to provide any input specified on the command-line as in-memory file. If no overlay file-system is provided, the Worker's dependency scanning file-system is used instead.

Returns: false if any errors occurred (with diagnostics reported to DiagConsumer), true otherwise.
