ILE C/C++ Compiler Reference
Specifies the level of the object's optimization.
|--+----------------------+-------------------------------------|
| .-10-. |
'-OPTIMIZE(--+-20-+--)-'
+-30-+
'-40-'
- 10
- Default setting. Generated code is not optimized. This level
has the shortest compile time.
- 20
- Some optimization is performed on the code.
- 30
- Full optimization is performed on the generated code.
- 40
- All optimizations done at level 30 are performed on the generated
code. In addition, code is eliminated from procedure prologue and
epilogue routines that enable instruction trace and call trace system
functions. Eliminating this code enables the creation of leaf
procedures. A leaf procedure contains no calls to other
procedures. Procedure call performance to a leaf procedure is
significantly faster than to a normal procedure.
