Conditional zero, if condition is nonzero
If xs2 contains a nonzero value, this instruction writes the value zero to xd. Otherwise, this instruction copies the contents of xs1 to xd. This instruction carries a syntactic dependency from both xs1 and xs2 to xd. Furthermore, if the Zkt extension is implemented, this instruction’s timing is independent of the data values in xs1 and xs2.
| This instruction must have data-independent timing when extension Zkt is enabled. |
