Constructor & Destructor Documentation

◆ VerifyDiagnosticConsumer()

VerifyDiagnosticConsumer::VerifyDiagnosticConsumer ( DiagnosticsEngine & Diags )

Create a new verifying diagnostic client, which will issue errors to the currently-attached diagnostic client when a diagnostic does not match what is expected (as indicated in the source file).

Definition at line 677 of file VerifyDiagnosticConsumer.cpp.

References HasNoDirectives.

◆ ~VerifyDiagnosticConsumer()

VerifyDiagnosticConsumer::~VerifyDiagnosticConsumer ( )

Member Function Documentation

◆ BeginSourceFile()

void VerifyDiagnosticConsumer::BeginSourceFile	(	const LangOptions &	LangOpts,
		const Preprocessor *	PP )

overridevirtual

Callback to inform the diagnostic client that processing of a source file is beginning.

Note that diagnostics may be emitted outside the processing of a source file, for example during the parsing of command line options. However, diagnostics with source range information are required to only be emitted in between BeginSourceFile() and EndSourceFile().

Parameters

LangOpts	The language options for the source file being processed.
PP	The preprocessor object being used for the source; this is optional, e.g., it may not be present when processing AST source files.

Reimplemented from clang::DiagnosticConsumer.

Definition at line 697 of file VerifyDiagnosticConsumer.cpp.

References clang::Preprocessor::getSourceManager().

◆ EndSourceFile()

void VerifyDiagnosticConsumer::EndSourceFile ( )

overridevirtual

Callback to inform the diagnostic client that processing of a source file has ended.

The diagnostic client should assume that any objects made available via BeginSourceFile() are inaccessible.

Reimplemented from clang::DiagnosticConsumer.

Definition at line 718 of file VerifyDiagnosticConsumer.cpp.

◆ HandleComment()

bool VerifyDiagnosticConsumer::HandleComment	(	Preprocessor &	PP,
		SourceRange	Comment )

overridevirtual

HandleComment - Hook into the preprocessor and extract comments containing expected errors and warnings.

Implements clang::CommentHandler.

Definition at line 780 of file VerifyDiagnosticConsumer.cpp.

References clang::C, clang::SourceRange::getBegin(), clang::SourceRange::getEnd(), clang::Preprocessor::getSourceManager(), ParseDirective(), and SM.

◆ HandleDiagnostic()

void VerifyDiagnosticConsumer::HandleDiagnostic	(	DiagnosticsEngine::Level	DiagLevel,
		const Diagnostic &	Info )

overridevirtual

Handle this diagnostic, reporting it to the user or capturing it to a log as needed.

The default implementation just keeps track of the total number of warnings and errors.

Reimplemented from clang::DiagnosticConsumer.

Definition at line 738 of file VerifyDiagnosticConsumer.cpp.

References clang::HeaderSearch::findModuleForHeader(), clang::Diagnostic::getLocation(), clang::Diagnostic::getSourceManager(), clang::Diagnostic::hasSourceManager(), IsUnparsed, IsUnparsedNoDirectives, clang::SourceLocation::isValid(), and UpdateParsedFileStatus().

◆ UpdateParsedFileStatus()

void VerifyDiagnosticConsumer::UpdateParsedFileStatus	(	SourceManager &	SM,
		FileID	FID,
		ParsedStatus	PS )

Update lists of parsed and unparsed files.

Definition at line 1047 of file VerifyDiagnosticConsumer.cpp.
