Count leading false in or construct bool vector with leading false.
operands: like Leftv XX:i
This counts the leading false elements in a bool vector.
| Core | In Slots | Latencies |
|---|---|---|
| Tin | E0 | 1 |
| Copper | E0 | 1 |
| Silver | E0 E1 E2 E3 | 1 |
| Gold | E0 | 1 |
operands: like Lefts xx:X
Constructs a bool vector with w elements of which the leading x elements are false and the rest true.
| Core | In Slots | Latencies |
|---|---|---|
| Tin | E0 | |
| Copper | E0 | |
