Usage Scenarios
Usage Scenarios
Code coverage analysis and profile-guided optimization have different usage
scenarios. With code coverage, you are usually trying to determine what portions
of your code are being executed during testing; the goal is to execute as much of
the application as possible. With profile-guided optimization, your objective should
be to limit the execution of your application to only those portions that are most
likely to execute under a typical workload.
