o CVT.S.W and CVT.W.S were reversed
...
o When unpacking an r5900 FP value,
was not treating IEEE-NaN's as very
large values.
o When packing an r5900 FP result from an infinite
precision intermediate value was saturating
to IEEE-MAX instead of r5900-MAX
o The least significant bit of the FP status
register did not stick to one.
