Unless you've got a spare ASE lying around with conditional execution
and a barrel shifter, I don't think this is in the cards.
Which isn't to say that someone couldn't write a good MIPS-specific
implementation, if they were a sufficiently good FP guru. But
my feeling is that ARM is more prone than MIPS to clever tricks that
are hard for a compiler to generate.
