[cfe-dev] Clang beginner - how to parse multiple files?

Can the different compilers use the same ASTContext?
E.g. say a.cpp contains Foo::bar() and b.cpp contains Foo::bar2(); will the
Foo type in the semantic DeclContext contain both foo and foo2 after
parsing both files?

Could you please provide an example how to setup the parsers?

Many thanks,
