128-bit SVE
Gather (load) and sign extend 16-bit values into the 64-bit elements of (3), from a base address (Xn/base), plus each corresponding 64-bit offset from (2). If the predicate bit from (1) corresponding to an element in (3) is zero, that load is skipped, and cannot cause a fault, and the element is set to zero.
256-bit SVE
Gather (load) and sign extend 16-bit values into the 64-bit elements of (3), from a base address (Xn/base), plus each corresponding 64-bit offset from (2). If the predicate bit from (1) corresponding to an element in (3) is zero, that load is skipped, and cannot cause a fault, and the element is set to zero.
512-bit SVE
Gather (load) and sign extend 16-bit values into the 64-bit elements of (3), from a base address (Xn/base), plus each corresponding 64-bit offset from (2). If the predicate bit from (1) corresponding to an element in (3) is zero, that load is skipped, and cannot cause a fault, and the element is set to zero.

1024-bit SVE
Gather (load) and sign extend 16-bit values into the 64-bit elements of (3), from a base address (Xn/base), plus each corresponding 64-bit offset from (2). If the predicate bit from (1) corresponding to an element in (3) is zero, that load is skipped, and cannot cause a fault, and the element is set to zero.
2048-bit SVE
Gather (load) and sign extend 16-bit values into the 64-bit elements of (3), from a base address (Xn/base), plus each corresponding 64-bit offset from (2). If the predicate bit from (1) corresponding to an element in (3) is zero, that load is skipped, and cannot cause a fault, and the element is set to zero.
