Yes, I've got SSE. That's very interesting. I'll give it a try!
Does LuaJIT use much SSE2 that isn't in SSE? I seem to recall SSE2
added mostly integer operations, and a few cache prefetch type
instructions, but not so much in the way of floating point
instructions.
If SSE2 is used only minimally maybe it would still be worthwhile to add support for non-SSE2 but SSE capable platforms?
Even if this would increase the number of potential users just a tiny bit. I could try to do the patch myself but only if the required changes are small. I don't know the source code at all so any pointers on how to start would be appreciated.
