7d93d53871 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.
