SMAX (immediate) Signed maximum with immediate (unpredicated) Determine the signed maximum of an immediate and each element of the source vector, and destructively place the results in the corresponding elements of the source vector. The immediate is a signed 8-bit value in the range -128 to +127, inclusive. This instruction is unpredicated.
