Pointer inequality. The highest 3 bits of pointers are reserved for user purposes like garbage collection, and as such are ignored in pointer comparisons.


neqp(p x, p y) → p r0

operands: like Eqlp pp:p

neqp(conditioncode) → p r0

operands: like Eqlp pp:p

Gets the inequality condition code of the ganged operation and puts it on the belt.
