Conditional move is effectly a special case of a predicated
instruction... and I think that all predicated instructions can possibly
be implemented later in LLVM. It would significantly change things, and
-it doesn't seem to be very neccesary right now. It would seem to
+it doesn't seem to be very necessary right now. It would seem to
complicate flow control analysis a LOT in the virtual machine. I would
tend to prefer that a predicated architecture like IA64 convert from a
"basic block" representation to a predicated rep as part of it's dynamic
