/* Special/non-trivial issues of this code:
*
* 1) %o5 is preserved from VISEntryHalf to VISExitHalf
* 2) Only low 32 FPU registers are used so that only the
* lower half of the FPU register set is dirtied by this
* code. This is especially important in the kernel.
* 3) This code never prefetches cachelines past the end
* of the source buffer.
*
* The cheetah's flexible spine, oversized liver, enlarged heart,
* slender muscular body, and claws make it the swiftest hunter
* in Africa and the fastest animal on land. Can reach speeds
* of up to 2.4GB per second.
