128-bit SVE
Interleave 8-bit elements from four consecutive registers (2), (3), (4), and (5), and store them to the memory operand (6). If the predicate bit from (1) corresponding to an element in (2), (3), (4), and (5) is zero, those four contiguous stores are skipped, and cannot cause a fault, and the corresponding values in memory are unchanged.
256-bit SVE
Interleave 8-bit elements from four consecutive registers (2), (3), (4), and (5), and store them to the memory operand (6). If the predicate bit from (1) corresponding to an element in (2), (3), (4), and (5) is zero, those four contiguous stores are skipped, and cannot cause a fault, and the corresponding values in memory are unchanged.
512-bit SVE
Interleave 8-bit elements from four consecutive registers (2), (3), (4), and (5), and store them to the memory operand (6). If the predicate bit from (1) corresponding to an element in (2), (3), (4), and (5) is zero, those four contiguous stores are skipped, and cannot cause a fault, and the corresponding values in memory are unchanged.

1024-bit SVE
Interleave 8-bit elements from four consecutive registers (2), (3), (4), and (5), and store them to the memory operand (6). If the predicate bit from (1) corresponding to an element in (2), (3), (4), and (5) is zero, those four contiguous stores are skipped, and cannot cause a fault, and the corresponding values in memory are unchanged.
2048-bit SVE
Interleave 8-bit elements from four consecutive registers (2), (3), (4), and (5), and store them to the memory operand (6). If the predicate bit from (1) corresponding to an element in (2), (3), (4), and (5) is zero, those four contiguous stores are skipped, and cannot cause a fault, and the corresponding values in memory are unchanged.
