Use this panel to control compiler optimizations. The compiler's optimizer can apply any of its optimizations in either global or non-global optimization mode. You can apply global optimization at the end of the development cycle, after compiling and optimizing all source files individually or in groups.
The following figure shows the Optimization panel.
The following table lists and describes the optimization options for RS08 compiler.
