Interesting, looking forward to reading them.

But certainly processors can do more than they do. For example, doesn't x86 offer a memcpy or memmove instruction and just decode it as the right "fast" way, versus making people update their stdlib with complicated code?

I don't really know what I'm talking about, but it seems I often run across long discussions where people are trying all sorts of instruction sequences and they're model-specific and it just seems like there should be a few more higher-level instructions exposed. (Well perhaps that's the point of all the SSE and AVX instructions.)
