Help text

An architecture selects this when it has implemented refcount_t using open coded assembly primitives that provide an optimized refcount_t implementation, possibly at the expense of some full refcount state checks of REFCOUNT_FULL=y.

The refcount overflow check behavior, however, must be retained. Catching overflows is the primary security concern for protecting against bugs in reference counts.
