For the JS bindings, the usual way is to add the [Custom] flag to the
IDL property or method and put your code in a *Custom file (see the
files in WebCore/bindings/js/*Custom and their corresponding IDLs in

For broader changes or other WebCore generated files (.in files for
example), we modify the scripts and / or extend the language.

Your question is a big broad so this is a generic answer (which misses
some file type like the gperf generated ones). If you give us more
details, we can give you a more precise answer.
