I updated the patch and made sure the behavior keep the order of configuration.

But if the case like:

1. enabled in binary
2. enabled in config file
3. enabled in command-line option `-checks`

Only command-line option `-checks` will be diagnosed, since the processor order of configuration is binary -> config file -> command-line option `-checks`.
