Provides clauses in binary module descriptor but not in source

However, `java -d jdk.internal.vm.compiler | grep Core` shows me the provider clause exists in the binary module descriptor. Is this done auto-magically by javac when building the module? If not, is it in the make files somewhere? I'm asking because there are new service providers being added in Graal.

The build for that module is complex as it runs an annotation processor 
and generates a module-info.java.extra (see 
support/gensrc/jdk.internal.vm.compiler/ in the build output) that is 
merged with the module-info.java before it is compiled. So no javac magic.
