/* To correctly instrument the fortify wrapper clang requires the
pass_object_size attribute, and the attribute has the restriction that the
argument needs to be 'const'. Furthermore, to make it usable with C
interfaces, clang provides the overload attribute, which provides a C++
like function overload support. The overloaded fortify wrapper with the
pass_object_size attribute has precedence over the default symbol.
Also, clang does not support __va_arg_pack, so variadic functions are
expanded to issue va_arg implementations. The error function must not have
bodies (address takes are expanded to nonfortified calls), and with
__fortify_function compiler might still create a body with the C++
mangling name (due to the overload attribute). In this case, the function
is defined with __fortify_function_error_function macro instead.
The argument size check is also done with a clang-only attribute,
__attribute__ ((__diagnose_if__ (...))), different than gcc which calls
symbol_chk_warn alias with uses __warnattr attribute.
The pass_object_size was added on clang 4.0, __diagnose_if__ on 5.0,
