This is true, but they do not support x87 instructions too. (like all
ARM cpus and MIPS cpus who does not have hardware floating-point
support at all)

I'd say 99% embedded cpus support sse or have no hardware
floating-point support at all.



The fact is we could use integer as lua number and avoid
floating-point operations, I don't know if LuaJit works under this
condition without sse, but I think this is a definitely useful
feature: support non-sse CPU when lua number is integer.
