There exists similar instructions in VSX (not IEEE754-2019 though). + This is frequently used to justify not adding them. However SVP64/VSX may have different meaning from SVP64/SFFS, so it is *really* crucial to have SFFS ops even if "equivalent" to VSX in order for SVP64 to not be compromised (non-orthogonal).
