Detailed Description

CompilerInstance - Helper class for managing a single instance of the Clang compiler.

The CompilerInstance serves two purposes: (1) It manages the various objects which are necessary to run the compiler, for example the preprocessor, the target information, and the AST context. (2) It provides utility routines for constructing and manipulating the common Clang objects.

The compiler instance generally owns the instance of all the objects that it manages. However, clients can still share objects by manually setting the object and retaking ownership prior to destroying the CompilerInstance.

The compiler instance is intended to simplify clients, but not to lock them in to the compiler instance for everything. When possible, utility functions come in two forms; a short form that reuses the CompilerInstance objects, and a long form that takes explicit instances of any required objects.

Create the default output file (from the invocation's options) and add it to the list of tracked output files.

The files created by this are usually removed on signal, and, depending on FrontendOptions, may also use a temporary file (that is, the data is written to a temporary file which will atomically replace the target output on success).

Returns: - Null on error.

Note that this routine also replaces the diagnostic client, allocating one if one is not provided.

Parameters

ShouldOwnClient	If Client is non-NULL, specifies whether the diagnostic object should take ownership of the client.

	)

static

Create a DiagnosticsEngine object with a the TextDiagnosticPrinter.

If no diagnostic client is provided, this creates a DiagnosticConsumer that is owned by the returned diagnostic object, if using directly the caller is responsible for releasing the returned DiagnosticsEngine's client eventually.

Parameters

Opts	- The diagnostic options; note that the created text diagnostic object contains a reference to these options.
Client	If non-NULL, a diagnostic client that will be attached to (and, then, owned by) the returned DiagnosticsEngine object.
CodeGenOpts	If non-NULL, the code gen options in use, which may be used by some diagnostics printers (for logging purposes only).

Returns: The new object on success, or null on failure.

◆ createTarget()

bool CompilerInstance::createTarget ( )

◆ ExecuteAction()

bool CompilerInstance::ExecuteAction ( FrontendAction & Act )

ExecuteAction - Execute the provided action against the compiler's CompilerInvocation object.

This function makes the following assumptions:

The invocation options should be initialized. This function does not handle the '-help' or '-version' options, clients should handle those directly.
The diagnostics engine should have already been created by the client.
No other CompilerInstance state should have been initialized (this is an unchecked error).
Clients should have initialized any LLVM target features that may be required.
Clients should eventually call llvm_shutdown() upon the completion of this routine to ensure that any managed objects are properly destroyed.

Note that this routine may write output to 'stderr'.

Parameters

Act	- The action to execute.

Returns: - True on success.

◆ loadGlobalModuleIndex()

GlobalModuleIndex * CompilerInstance::loadGlobalModuleIndex ( SourceLocation TriggerLoc )

overridevirtual

Load, create, or return global module.

This function returns an existing global module index, if one had already been loaded or created, or loads one if it exists, or creates one if it doesn't exist. Also, importantly, if the index doesn't cover all the modules in the module map, it will be update to do so here, because of its use in searching for needed module imports and associated fixit messages.

Parameters

TriggerLoc The location for what triggered the load.

Returns: Returns null if load failed.

◆ loadModule()

ModuleLoadResult CompilerInstance::loadModule	(	SourceLocation	ImportLoc,
		ModuleIdPath	Path,
		Module::NameVisibilityKind	Visibility,
		bool	IsInclusionDirective
	)

overridevirtual

Attempt to load the given module.

This routine attempts to load the module described by the given parameters. If there is a module cache, this may implicitly compile the module before loading it.

Parameters

ImportLoc	The location of the 'import' keyword.
Path	The identifiers (and their locations) of the module "path", e.g., "std.vector" would be split into "std" and "vector".
Visibility	The visibility provided for the names in the loaded module.
IsInclusionDirective	Indicates that this module is being loaded implicitly, due to the presence of an inclusion directive. Otherwise, it is being loaded due to an import declaration.

Returns: If successful, returns the loaded module. Otherwise, returns NULL to indicate that the module could not be loaded.
