vwsub.vv
Vector widening signed subtraction
Performs signed subtraction on elements from vector registers vs2 and vs1, widens the results, and stores them in vector register vd, using vector mask vm. The operation follows standard signed arithmetic rules.
| This instruction must have data-independent timing when extension Zkt is enabled. |
