◆ applyNullability()

static void applyNullability	(	Sema &	S,
		Decl *	D,
		NullabilityKind	Nullability,
		VersionedInfoMetadata	Metadata
	)

static

Apply nullability to the given declaration.

Definition at line 51 of file SemaAPINotes.cpp.

◆ ASTAllocateString()

static StringRef ASTAllocateString	(	ASTContext &	Ctx,
		StringRef	String
	)

static

Copy a string into ASTContext-allocated memory.

Definition at line 111 of file SemaAPINotes.cpp.

◆ checkAPINotesReplacementType()

static bool checkAPINotesReplacementType	(	Sema &	S,
		SourceLocation	Loc,
		QualType	OrigType,
		QualType	ReplacementType
	)

static

Check that the replacement type provided by API notes is reasonable.

This is a very weak form of ABI check.

◆ isIndirectPointerType()

static bool isIndirectPointerType ( QualType Type )

static

Determine whether this is a multi-level pointer type.

Definition at line 41 of file SemaAPINotes.cpp.

References clang::Type::getPointeeType(), clang::Type::isAnyPointerType(), clang::Type::isMemberPointerType(), clang::QualType::isNull(), and clang::Type::isObjCObjectPointerType().

◆ maybeAttachUnversionedSwiftName()

template<typename SpecificInfo >

static void maybeAttachUnversionedSwiftName	(	Sema &	S,
		Decl *	D,
		const api_notes::APINotesReader::VersionedInfo< SpecificInfo >	Info
	)

static

If we're applying API notes with an active, non-default version, and the versioned API notes have a SwiftName but the declaration normally wouldn't have one, add a removal attribute to make it clear that the new SwiftName attribute only applies to the active version of D, not to all versions.

This must be run before processing API notes for D, because otherwise any existing SwiftName attribute will have been packaged up in a SwiftVersionedAdditionAttr.
