ST2B (scalar plus scalar): Contiguous store two-byte structures from two vectors (scalar index)

128-bit SVE

Interleave 8-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 8-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 8-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 8-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 8-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.
