Function Documentation

static unsigned getAccessFlag	(	AccessSpecifier	Access,
		const RecordDecl *	RD
	)		[static]

Convert an AccessSpecifier into the corresponding DIDescriptor flag. As an optimization, return 0 if the access specifier equals the default for the containing type.

Definition at line 810 of file CGDebugInfo.cpp.

References clang::AS_none, clang::AS_private, clang::AS_protected, clang::AS_public, clang::TagDecl::isClass(), clang::TagDecl::isStruct(), and clang::TagDecl::isUnion().

static SmallString<256> getUniqueTagTypeName	(	const TagType *	Ty,
		CodeGenModule &	CGM,
		llvm::DICompileUnit	TheCU
	)		[static]

In C++ mode, types have linkage, so we can rely on the ODR and on their mangled names, if they're external.

static bool hasDefaultGetterName	(	const ObjCPropertyDecl *	PD,
		const ObjCMethodDecl *	Getter
	)		[static]

Returns:

true if Getter has the default name for the property PD.

		const ObjCMethodDecl *	Setter
	)		[static]

Returns:
