128-bit SVE

Store 8-bit values from the two consecutive registers (2) and (3) to the memory operand (4). After decoding the predicate (1) from its predicate-as-counter representation to a double-length predicate, if the predicate bit corresponding to an element is zero, that store is skipped, and cannot cause a fault, and the corresponding value in memory is unchanged. The first register number (2) must be divisible by two.
256-bit SVE

Store 8-bit values from the two consecutive registers (2) and (3) to the memory operand (4). After decoding the predicate (1) from its predicate-as-counter representation to a double-length predicate, if the predicate bit corresponding to an element is zero, that store is skipped, and cannot cause a fault, and the corresponding value in memory is unchanged. The first register number (2) must be divisible by two.
512-bit SVE

Store 8-bit values from the two consecutive registers (2) and (3) to the memory operand (4). After decoding the predicate (1) from its predicate-as-counter representation to a double-length predicate, if the predicate bit corresponding to an element is zero, that store is skipped, and cannot cause a fault, and the corresponding value in memory is unchanged. The first register number (2) must be divisible by two.

1024-bit SVE

Store 8-bit values from the two consecutive registers (2) and (3) to the memory operand (4). After decoding the predicate (1) from its predicate-as-counter representation to a double-length predicate, if the predicate bit corresponding to an element is zero, that store is skipped, and cannot cause a fault, and the corresponding value in memory is unchanged. The first register number (2) must be divisible by two.
2048-bit SVE

Store 8-bit values from the two consecutive registers (2) and (3) to the memory operand (4). After decoding the predicate (1) from its predicate-as-counter representation to a double-length predicate, if the predicate bit corresponding to an element is zero, that store is skipped, and cannot cause a fault, and the corresponding value in memory is unchanged. The first register number (2) must be divisible by two.
