The compiler provides two options for optimizing for code size and performance:
This option causes the compiler to optimize mainly for code size. This is the default option.
This option causes the compiler to optimize mainly for speed.
For best results, you must build your application using the most appropriate command-line option.
These command-line options instruct the compiler to use optimizations
that deliver the effect wanted in the vast majority of cases. However,
it is not guaranteed that
-Otime always generates faster
code, or that
-Ospace always generates smaller
