## 128-bit SVE

Compute the bitwise-or of the active 64-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 64-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 64-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 64-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 64-bit elements from (1), storing the result in (3). If there are no active elements, the result is 0.
