Optimal compile flags for ultra2 & power2

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.
