Profile-guided Optimizations

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.
