Save As... 

Displays the Save As dialog box to save the current configuration's options to a file that can be loaded as a named option set.  

Load... 

Displays the Apply Option Set dialog box to apply the options in a named option set to the current configuration.  

Optimizations options 

Description 

None (-Od)* 

Disables all optimization settings, including ones which you may have specifically set and those that would normally be performed as part of the speed/size trade-off.
Because this disables code compaction (tail merging) and cross-jump optimizations, using this option can keep the debugger from jumping around or returning from a function without warning, which makes stepping through code easier to follow.
This is the default.  

Size (-O1) 

Sets an aggregate of optimization options that tells the compiler to optimize your code for size. For example, the compiler scans the generated code for duplicate sequences. When such sequences warrant, the optimizer replaces one sequence of code with a jump to the other and eliminates the first piece of code. This occurs most often with switch statements. The compiler optimizes for size by choosing the smallest code sequence possible.  

Speed (-O2) 

This switch sets an aggregate of optimization options that tells the compiler to optimize your code for speed.  

Selected 

Chooses specific optimizations to enable.
Click Select All to enable all optimizations in the list.
Click Clear All to clear all selected optimizations in the list
Click Defaults to enable the default optimizations in the list  

General option 

Description 

Default 

Saves the current settings as the default for each new project.
