You are correct, for the case of min/max -- and indeed all of the other arithmetic added in this patch -- we do not need VSX. However, the load/store instructions added by this patch do require VSX. AFAIK, there is exactly one v2.07 core design, the power8. It has both Altivec and VSX, so it's really only a technicality to check both v2.07 + Altivec + VSX, but I do anyway. It does not seem worthwhile to decompose these checks further. r~
