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

128-bit SVE

Multiply each odd unsigned 32-bit integer from (2), with the unsigned 32-bit integer specified by imm from (1), then subtract this from to the 64-bit integer from (3), and set (4) to the result.

256-bit SVE

Multiply each odd unsigned 32-bit integer from (2), with the unsigned 32-bit integer specified by imm from (1), then subtract this from to the 64-bit integer from (3), and set (4) to the result.

512-bit SVE

Multiply each odd unsigned 32-bit integer from (2), with the unsigned 32-bit integer specified by imm from (1), then subtract this from to the 64-bit integer from (3), and set (4) to the result.

1024-bit SVE

Multiply each odd unsigned 32-bit integer from (2), with the unsigned 32-bit integer specified by imm from (1), then subtract this from to the 64-bit integer from (3), and set (4) to the result.

2048-bit SVE

Multiply each odd unsigned 32-bit integer from (2), with the unsigned 32-bit integer specified by imm from (1), then subtract this from to the 64-bit integer from (3), and set (4) to the result.
