svuint64_t svmlalb_lane[_u64](svuint64_t op1, svuint32_t op2, svuint32_t op3, uint64_t imm_index)

## 128-bit SVE

Multiply each even unsigned 32-bit integer from (2), with the unsigned 32-bit integer specified by `imm`

from (1), then add this to the 64-bit integer from (3), and set (4) to the result.

## 256-bit SVE

Multiply each even unsigned 32-bit integer from (2), with the unsigned 32-bit integer specified by `imm`

from (1), then add this to the 64-bit integer from (3), and set (4) to the result.

## 512-bit SVE

Multiply each even unsigned 32-bit integer from (2), with the unsigned 32-bit integer specified by `imm`

from (1), then add this to the 64-bit integer from (3), and set (4) to the result.

## Larger sizes

## 1024-bit SVE

Multiply each even unsigned 32-bit integer from (2), with the unsigned 32-bit integer specified by `imm`

from (1), then add this to the 64-bit integer from (3), and set (4) to the result.

## 2048-bit SVE

Multiply each even unsigned 32-bit integer from (2), with the unsigned 32-bit integer specified by `imm`
