At each level of optimization, you can control the aggressiveness
of the optimizations performed.
Use the +Oconservative option at any optimization level, if you are not sure
if your code conforms to standards. This option provides more safety.
Use the +Oaggressive option at all optimization levels for best performance
when you are willing to risk changes to the behavior of your programs.
Using the +Oaggressive option can cause your program to have compilation
or run-time problems that require troubleshooting.
