128-bit SVE

Fill the 8-bit lanes of (3), with values starting from (1) in the lowest lane, and incrementing by (2) for each subsequent lane. The immediate value is limited to -16 ≤ imm ≤ 15.

256-bit SVE

Fill the 8-bit lanes of (3), with values starting from (1) in the lowest lane, and incrementing by (2) for each subsequent lane. The immediate value is limited to -16 ≤ imm ≤ 15.

512-bit SVE

Fill the 8-bit lanes of (3), with values starting from (1) in the lowest lane, and incrementing by (2) for each subsequent lane. The immediate value is limited to -16 ≤ imm ≤ 15.
