LD1SW (scalar plus vector): Gather load signed words to vector (vector index)
LD1SW { Zt.D }, Pg/Z, [Xn, Zm.D, SXTW #2] (SVE+NS
LD1SW { Zt.D }, Pg/Z, [Xn, Zm.D, UXTW #2] (SVE+NS
128-bit SVE
Gather (load) and sign extend 32-bit values into (3), from a base address (Xn/base), plus each corresponding sign-or-zero-extended 32-bit offset from the low halves of the 64-bit elements of (2) multiplied by four. 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 32-bit values into (3), from a base address (Xn/base), plus each corresponding sign-or-zero-extended 32-bit offset from the low halves of the 64-bit elements of (2) multiplied by four. 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 32-bit values into (3), from a base address (Xn/base), plus each corresponding sign-or-zero-extended 32-bit offset from the low halves of the 64-bit elements of (2) multiplied by four. 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 32-bit values into (3), from a base address (Xn/base), plus each corresponding sign-or-zero-extended 32-bit offset from the low halves of the 64-bit elements of (2) multiplied by four. 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 32-bit values into (3), from a base address (Xn/base), plus each corresponding sign-or-zero-extended 32-bit offset from the low halves of the 64-bit elements of (2) multiplied by four. 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.
