128-bit SVE
Load 8-bit values from the memory operand (1) and sign extend them, writing the results to the 64-bit elements of (2). If the predicate bit corresponding to an element in (2) is zero, that load is skipped, and cannot cause a fault, and the element is set to zero.
256-bit SVE
Load 8-bit values from the memory operand (1) and sign extend them, writing the results to the 64-bit elements of (2). If the predicate bit corresponding to an element in (2) is zero, that load is skipped, and cannot cause a fault, and the element is set to zero.
512-bit SVE
Load 8-bit values from the memory operand (1) and sign extend them, writing the results to the 64-bit elements of (2). If the predicate bit corresponding to an element in (2) is zero, that load is skipped, and cannot cause a fault, and the element is set to zero.

1024-bit SVE
Load 8-bit values from the memory operand (1) and sign extend them, writing the results to the 64-bit elements of (2). If the predicate bit corresponding to an element in (2) is zero, that load is skipped, and cannot cause a fault, and the element is set to zero.
2048-bit SVE
Load 8-bit values from the memory operand (1) and sign extend them, writing the results to the 64-bit elements of (2). If the predicate bit corresponding to an element in (2) is zero, that load is skipped, and cannot cause a fault, and the element is set to zero.
