Detailed Description

Concrete class used by the front-end to report problems and issues.

This massages the diagnostics (e.g. handling things like "report warnings as errors" and passes them off to the DiagnosticConsumer for reporting to the user. DiagnosticsEngine is tied to one translation unit and one SourceManager.

SetDelayedDiagnostic()

void DiagnosticsEngine::SetDelayedDiagnostic	(	unsigned	DiagID,
		StringRef	Arg1 = "",
		StringRef	Arg2 = "",
		StringRef	Arg3 = ""
	)

Set the "delayed" diagnostic that will be emitted once the current diagnostic completes.

If a diagnostic is already in-flight but the front end must report a problem (e.g., with an inconsistent file system state), this routine sets a "delayed" diagnostic that will be emitted after the current diagnostic completes. This should only be used for fatal errors detected at inconvenient times. If emitting a delayed diagnostic causes a second delayed diagnostic to be introduced, that second delayed diagnostic will be ignored.

Parameters

DiagID	The ID of the diagnostic being delayed.
Arg1	A string argument that will be provided to the diagnostic. A copy of this string will be stored in the DiagnosticsEngine object itself.
Arg2	A string argument that will be provided to the diagnostic. A copy of this string will be stored in the DiagnosticsEngine object itself.
Arg3	A string argument that will be provided to the diagnostic. A copy of this string will be stored in the DiagnosticsEngine object itself.

setExtensionHandlingBehavior()

void clang::DiagnosticsEngine::setExtensionHandlingBehavior ( diag::Severity  H )

void clang::DiagnosticsEngine::setLastDiagnosticIgnored ( bool  Ignored )

Pretend that the last diagnostic issued was ignored, so any subsequent notes will be suppressed, or restore a prior ignoring state after ignoring some diagnostics and their notes, possibly in the middle of another diagnostic.

This can be used by clients who suppress diagnostics themselves.

setSeverity()

void DiagnosticsEngine::setSeverity	(	diag::kind	Diag,

This allows the client to specify that certain warnings are ignored.

Notes can never be mapped, errors can only be mapped to fatal, and WARNINGs and EXTENSIONs can be mapped arbitrarily.

Parameters

Loc	The source location that this change of diagnostic state should take affect. It can be null if we are setting the latest state.

Change an entire diagnostic group (e.g.

Returns

true (and ignores the request) if "Group" was unknown, false otherwise.

Parameters

Flavor	The flavor of group to affect. -Rfoo does not affect the state of the -Wfoo group and vice versa.
Loc	The source location that this change of diagnostic state should take affect. It can be null if we are setting the state from command-line.
