Combining Optimization Parameters on HP-UX
Optimization parameters that affect code size, compile-time, and the
aggressiveness of the optimizations performed can be combined with a
level of optimization.
For example, to specify conservative optimizations at level 2 and disable
code-expanding optimizations, use:
cc +O2 +Oconservative +Osize sourcefile.c
+Olimit and +Osize can be used with either +Oaggressive or
+Oconservative.
You cannot use +Oaggressive with +Oconservative.
