When you compile a program with the +Oreport[=report_type] optimization option at the +O3 and +O4 levels, the compiler generates an Optimization
Report for each program unit. The +Oreport[=report_type] option determines the report’s contents
based on the value of report_type, as shown in Table 8-1 “Optimization Report contents”.
Table 8-1 Optimization Report contents
| report_type values | Report contents |
|---|
| all | Loop Report and Privatization Table |
| loop | Loop Report |
| private | Loop Report and Privatization Table |
| report_type not given (default) | Loop Report |
The +Onoreport option does not accept any of the report_type values. Sample
Optimization Reports are provided throughout this chapter.
