:
a = (a b) ? a : b;
Which is exactly how it is coded in qemu (at least in v0.8.2). This
relies upon the fact that the greater-than comparison returns false
anytime there is an unordered operand (NaN), for either operand -- in
which case the result is the second argument.

Can someone elaborate on this a little? What is the difference
between the SOFTMMU and the mmap()? Should I be using the
--enable-system or the --disable-system for win32 guest on i386 debian
host? Can someone give a little more insight
there is a big performance hit using the software mmu, as each
target load or store instruction is expanded into 20-30 host
instructions to perform the translation. Is there a way to build the
qemu-system-* emulators using the mmap() feature mentioned in the
documentation?
