128-bit SVE

For each odd 16-bit float calculate (1) * (2), and add that to the 32-bit float from (3), then set (4) to the result.
256-bit SVE

For each odd 16-bit float calculate (1) * (2), and add that to the 32-bit float from (3), then set (4) to the result.
512-bit SVE

For each odd 16-bit float calculate (1) * (2), and add that to the 32-bit float from (3), then set (4) to the result.
