That makes me wonder why we still don't have 3 simple to use instructions that do equivalent of memmove(), memcpy() and memset() all in hardware in the best possible way with the respect of block size, alignment, caches, chipset, you-name-it? Virtually every program would benefit from such instructions. -Maxim
