Is there a gcc flag to stop the Sun Ultra From handling denormalized numbers in
software and treat them as zero instead? My lab does a lot of computations and
when a denormalized number is encountered it really slows down computation.
We were wondering why a 10 hour run on a Sparc 10 was not finishing in a week 
on the new Ultra.

Thanks
