TreeTransform and adding Attr to the source


we have a source-to-source tool using an ASTConsumer and TreeTransform transformation. I am now trying to add an attribute to the AST so it shows up in my target file as well, therefore I add it to a Decl such as

D->addAttr( ::new (SemaRef.Context) AnnotateAttr("hallo"));


D->addAttr( ::new (SemaRef.Context)NoinlineAttr());

But it does not show up. Should this show up and I am doing something wrong or is this not supported using TreeTransform

Thanks for your help,
