- /* 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.
