| Linux: | -Obn |
| Windows: | /Obn |
| n | Is the inline function expansion level. Possible values are 0, 1, and 2. |
|
Ob2 |
If option O2 is specified or is in effect by default. |
|
Ob0 |
If option -O0 (Linux) or /Od (Windows) is specified |
This option specifies the level of inline function expansion. Inlining procedures can greatly improve the run-time performance for certain programs.
Option |
Description |
|---|---|
| Ob0 | Disables inlining of user-defined functions. However, statement functions are always inlined. |
| Ob1 | Enables inlining of functions declared with the __inline keyword. Also enables inlining according to the C++ language. |
| Ob2 | Enables inlining of any function. However, the compiler decides which functions are inlined. This option enables interprocedural optimizations and has the same effect as specifying option Qip. |
