128-bit SVE
Set all 8-bit lanes of (2) to the element from (1) specified by imm (or zero, if imm ≥ 16).
256-bit SVE
Set all 8-bit lanes of (2) to the element from (1) specified by imm (or zero, if imm ≥ 32).
512-bit SVE
Set all 8-bit lanes of (2) to the element from (1) specified by imm.
Larger sizes
1024-bit SVE
Set all 8-bit lanes of (2) to the element from (1) specified by imm. The immediate is limited to 0 ≤ imm < 64, so only elements from the low half of (1) may be specified on 1024-bit SVE.
2048-bit SVE
Set all 8-bit lanes of (2) to the element from (1) specified by imm. The immediate is limited to 0 ≤ imm < 64, so only elements from the low quarter of (1) may be specified on 2048-bit SVE.
