The optimization is not directly connected to the
architectural options.
SUN's cc/CC  has  five optimization levels  from
-xO1 to -xO5, and also a "-fast"  option that flips a
whole host of flags inluding "-xO5" . In the manual you are advised
to only use -fast on application code , not librarycode.
