No idea. That's what Paul asked you to narrow down. > Sse2 was introduced in cpus 11 years ago, so I think it would be useful > to add support for all missing instructions to avoid more cases like > this (and it seems to improve performance too, comparing the same task > executed with/without sse2). The reason we didn't add any more of the SSE insns so far is that we don't expect them to be used for accessing MMIO. Once we learn they're needed, we'll add emulation for them, but you realize this is a significant task?
