--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Some of these makes sense. gcc/asan.c makes sense: #define DEF_SANITIZER_BUILTIN(ENUM, NAME, TYPE, ATTRS) \ do { \ decl = add_builtin_function ("__builtin_" NAME, TYPE, ENUM, \ BUILT_IN_NORMAL, NAME, NULL_TREE); \ set_call_expr_flags (decl, ATTRS); \ set_builtin_decl (ENUM, decl, true); \ } while (0); #include "sanitizer.def" /* -fsanitize=object-size uses __builtin_object_size, but that might not be available for e.g. Fortran at this point. We use DEF_SANITIZER_BUILTIN here only as a convenience macro. */ if ((flag_sanitize & SANITIZE_OBJECT_SIZE) && !builtin_decl_implicit_p (BUILT_IN_OBJECT_SIZE)) DEF_SANITIZER_BUILTIN (BUILT_IN_OBJECT_SIZE, "object_size", BT_FN_SIZE_CONST_PTR_INT, ATTR_PURE_NOTHROW_LEAF_LIST) ---- CUT ----- DEF_SANITIZER_BUILTIN is used inside sanitizer.def without the semi-colon.
