| 198 | /* To correctly instrument the fortify wrapper clang requires the | ||

| 200 | argument needs to be 'const'. Furthermore, to make it usable with C | ||
| 201 | interfaces, clang provides the overload attribute, which provides a C++ | ||
| 202 | like function overload support. The overloaded fortify wrapper with the | ||
| 203 | pass_object_size attribute has precedence over the default symbol. | ||
| 204 | |||
| 205 | Also, clang does not support __va_arg_pack, so variadic functions are | ||
| 206 | expanded to issue va_arg implementations. The error function must not have | ||
| 207 | bodies (address takes are expanded to nonfortified calls), and with | ||
| 208 | __fortify_function compiler might still create a body with the C++ | ||
| 209 | mangling name (due to the overload attribute). In this case, the function | ||
| 210 | is defined with __fortify_function_error_function macro instead. | ||
| 211 | |||
