This option instructs the compiler to perform optimizations to reduce image size at the expense of a possible increase in execution time.
Use this option if code size is more critical than performance. For example, when the -Ospace option is selected, large structure copies are done by out‑of‑line function calls instead of inline code.
If required, you can compile the time‑critical parts of your code with ‑Otime, and the rest with ‑Ospace.
