[Frama-c-discuss] ACSL contracts lost during GFun modification in Ast Copy

Hello,

I'm working on a new Frama-C project built by the cmd "File.create_project_from_visitor" and I lose the ACSL contract if a make a change to a global function.

For example, if have a copy visitor like this:

  inherit Visitor.frama_c_copy prj
  method vglob_aux g =
    match g with
      | GFun (_)  ->
          Cil.ChangeTo [g]

All functions have lost their contract in the copy project.
Is there a way to keep contracts of the original function ? Perhaps throw the kernel_functions, but they are not handle by the visitor.

Thanks in advance,

Stephane
