128-bit SVE

Compute the bitwise-or of the active 8-bit elements from (1), storing the result in (3). If there are no active elements, the result is 0.

256-bit SVE

Compute the bitwise-or of the active 8-bit elements from (1), storing the result in (3). If there are no active elements, the result is 0.

512-bit SVE

Compute the bitwise-or of the active 8-bit elements from (1), storing the result in (3). If there are no active elements, the result is 0.

Larger sizes

1024-bit SVE

Compute the bitwise-or of the active 8-bit elements from (1), storing the result in (3). If there are no active elements, the result is 0.

2048-bit SVE

Compute the bitwise-or of the active 8-bit elements from (1), storing the result in (3). If there are no active elements, the result is 0.
