Pointer equality. The highest 3 bits of pointers are reserved for user purposes like garbage collection, and as such are ignored in pointer comparisons.
operands: like Eqlp pp:p
| Core | In Slots | Latencies |
|---|---|---|
| Tin | E0 | 2 |
| Copper | E0 E1 | 2 |
| Silver | E0 E1 E2 E3 | 2 |
| Gold | E0 E1 E2 E3 E4 E5 E6 E7 | 2 |
| Decimal8 | E0 E1 E2 E3 | 2 |
| Decimal16 | E0 E1 E2 E3 | 2 |
eqlp(conditioncode) → p r0
operands: like Eqlp pp:p
Gets the inequality condition code of the ganged operation and puts it on the belt.
related operations: neq, gtr, geq, lss, leq, carry, overflow, fault
