[Frama-c-discuss] RE : RE : How to discard a visiting glob?

Dear David,

My solution works in the general case. Actually, in the special case of globals, an alternative solution would be to redefine vglob_aux like in your example in order to return an empty list (since this method returns a list of globals and not only a single one). Both solutions work, so the best choice (the easiest one to implement) depends on what you really want to do on the AST.

Julien

Dear Julien,

It is really helpful to me.
Following your suggestion, I choose to create a new project by using
the new cil_types.file without that visited global.
Thank you very much.
