128-bit SVE
Interleave 64-bit elements from two consecutive registers (2) and (3), and store them to the memory operand (4). If the predicate bit from (1) corresponding to an element in (2) and (3) is zero, those two contiguous stores are skipped, and cannot cause a fault, and the corresponding values in memory are unchanged.
256-bit SVE
Interleave 64-bit elements from two consecutive registers (2) and (3), and store them to the memory operand (4). If the predicate bit from (1) corresponding to an element in (2) and (3) is zero, those two contiguous stores are skipped, and cannot cause a fault, and the corresponding values in memory are unchanged.
512-bit SVE
Interleave 64-bit elements from two consecutive registers (2) and (3), and store them to the memory operand (4). If the predicate bit from (1) corresponding to an element in (2) and (3) is zero, those two contiguous stores are skipped, and cannot cause a fault, and the corresponding values in memory are unchanged.

1024-bit SVE
Interleave 64-bit elements from two consecutive registers (2) and (3), and store them to the memory operand (4). If the predicate bit from (1) corresponding to an element in (2) and (3) is zero, those two contiguous stores are skipped, and cannot cause a fault, and the corresponding values in memory are unchanged.
2048-bit SVE
Interleave 64-bit elements from two consecutive registers (2) and (3), and store them to the memory operand (4). If the predicate bit from (1) corresponding to an element in (2) and (3) is zero, those two contiguous stores are skipped, and cannot cause a fault, and the corresponding values in memory are unchanged.
