Enumerators
| Name | Value | Comment |
|---|---|---|
| SK_Broadcast | 0 | Broadcast element 0 to all other elements. |
| SK_Reverse | 1 | Reverse the order of the vector. |

| SK_Transpose | 3 | Transpose two vectors. |
| SK_InsertSubvector | 4 | InsertSubvector. Index indicates start offset. |
| SK_ExtractSubvector | 5 | ExtractSubvector Index indicates start offset. |
| SK_PermuteTwoSrc | 6 | Merge elements from two source vectors into one with any shuffle mask. |
| SK_PermuteSingleSrc | 7 | Shuffle elements of single source vector with any shuffle mask. |
