clang::PointerAuthOptions Struct Reference

#include "clang/Basic/PointerAuthOptions.h"

Public Attributes
bool	ReturnAddresses = false
	Should return addresses be authenticated?
bool	AuthTraps = false
	Do authentication failures cause a trap?
bool	IndirectGotos = false
	Do indirect goto label addresses need to be authenticated?
bool	AArch64JumpTableHardening = false
	Use hardened lowering for jump-table dispatch?
PointerAuthSchema	FunctionPointers
	The ABI for C function pointers.
PointerAuthSchema	CXXVTablePointers
	The ABI for C++ virtual table pointers (the pointer to the table itself) as installed in an actual class instance.
PointerAuthSchema	CXXTypeInfoVTablePointer
	TypeInfo has external ABI requirements and is emitted without actually having parsed the libcxx definition, so we can't simply perform a look up.
PointerAuthSchema	CXXVTTVTablePointers
	The ABI for C++ virtual table pointers as installed in a VTT.
PointerAuthSchema	CXXVirtualFunctionPointers
	The ABI for most C++ virtual function pointers, i.e. v-table entries.
PointerAuthSchema	CXXVirtualVariadicFunctionPointers
	The ABI for variadic C++ virtual function pointers.
PointerAuthSchema	CXXMemberFunctionPointers
	The ABI for C++ member function pointers.
PointerAuthSchema	InitFiniPointers
	The ABI for function addresses in .init_array and .fini_array.
