Re: [Xen-devel] SSE Instruction emulation in Xen

[Keir Fraser <keir.fraser@xxxxxxxxxxxxx>]

We emulate a few SSE instructions, like MOVQ. Just enough for emulation of
things like optimised memcpy() and memset() when applied to emulated device
mmio areas.

We don't plan to fully emulate all SSE instructions. Xen doesn't really need
it and it would greatly increase the size and complexity of the emulator. If
there is a genuine good reason, however, I might reconsider.
