Only two options are used in a basic profile-guided optimization. These options are:
-prof_gen[x]
-prof_use
| Option | Description |
|---|---|
| -prof_gen[x] |
Instructs the compiler to produce instrumented code in your object files in preparation for instrumented execution. NOTE: The dynamic information files are produced in phase 2 when you run the instrumented executable. |
| -prof_use |
Instructs the compiler to produce a profile-optimized executable and merges available dynamic information (.dyn) files into a pgopti.dpi file. If you perform multiple executions of the instrumented program, -prof_use merges the dynamic information files again and overwrites the previous pgopti.dpi file. |
