QEMU and Core 2 Duo disagree on the handling of NaNs it seems.

- this implies that MAXPS should leave the NaNs alone, no idea how
normative that is though (and no IA32 manual at hand)
Having looked at an IA32 manual I'd

The program below tests the 'maxps' instruction. When run on
qemu-0.9.0, host amd64, guest x86, guest OS redhat8, it prints:

scp the binary to a Core 2 (real) machine and run:
