128-bit SVE

Truncate each active 128-bit element of (1) to a 64-bit value, and store them to the memory operand (3). If the corresponding predicate bit from (2) is zero, that store is skipped, and cannot cause a fault, and the corresponding value in memory is unchanged.
256-bit SVE

Truncate each active 128-bit element of (1) to a 64-bit value, and store them to the memory operand (3). If the corresponding predicate bit from (2) is zero, that store is skipped, and cannot cause a fault, and the corresponding value in memory is unchanged.
512-bit SVE

Truncate each active 128-bit element of (1) to a 64-bit value, and store them to the memory operand (3). If the corresponding predicate bit from (2) is zero, that store is skipped, and cannot cause a fault, and the corresponding value in memory is unchanged.

1024-bit SVE

Truncate each active 128-bit element of (1) to a 64-bit value, and store them to the memory operand (3). If the corresponding predicate bit from (2) is zero, that store is skipped, and cannot cause a fault, and the corresponding value in memory is unchanged.
2048-bit SVE

Truncate each active 128-bit element of (1) to a 64-bit value, and store them to the memory operand (3). If the corresponding predicate bit from (2) is zero, that store is skipped, and cannot cause a fault, and the corresponding value in memory is unchanged.
