Enables interprocedural optimization between files.
- Is an optional integer that specifies the number of object files the compiler should create. The integer must be greater than or equal to 0.
- Multifile interprocedural optimization is not enabled.
This option enables interprocedural optimization between files. This is also called multifile interprocedural optimization (multifile IPO) or Whole Program Optimization (WPO).
When you specify this option, the compiler performs inline function expansion for calls to functions defined in separate files.
You cannot specify the names for the files that are created.
nis 0, the compiler decides whether to create one or more object files based on an estimate of the size of the application. It generates one object file for small applications, and two or more object files for large applications.
nis greater than 0, the compiler generates
nobject files, unless
