In theory one could also use versions additionally taking advantage of the prefetch cache with cheetah-class CPUs, in my worldstone runs these either didn't provide extra speedup (USIII+) in comparison to the existing spitfire versions or were even slightly slower (USIIIi) though, so they aren't committed for now. The basic problem leading to the VIS-based copy/zero functions being initially disabled for cheetah-class CPUs was solved by letting cheetah_init() clear DCR_IFPOE.
