Sun C compiler

Does anyone know of a way to change the optimizer on the sun compiler?
I'm using a sun 3/260 and I've noticed inefficiencies in the optimized
code.  Namely, using only 4 out of 8 address registers in an inner loop
when the program can clearly use 5.  Also, a compiled (i>0) becomes
 (!(i - 1 <= 0))

thanks
