I was wondering what flags people use for best FP performance on these -
a) Sun ultra2
b) IBM Power2.
There's an additional quirk - a lot of the data I have to work with is 32bit
FP, so avoiding costly conversions between double & single precision (which is
a characteristic of the Power2 chipset) is important.
