I am trying to migrate a plugin for Frama-C Fluorine version to Frama-C Aluminium. When doing so, I cannot find the appropriate replacement for function Db.Value.AfterTable.find, the closest one I found is Db.Value.AfterTable_By_Callstack.find. However, that function now returns different type, which is Db.Value.AfterTable_By_Callstack.data = Db.Value.state Value_types.Callstack.Hashtbl.t, rather than Db.Value.state in Frama-C Fluorine. Could anyone please help me with this?

Many thanks, Truc

Indeed, the information is now more precise. But you can compute the state by joining the states by call stack with :

let state = Value_callstack.Callstack.Hashtbl.fold
      (fun _cs state acc -> Cvalue.Model.join acc state)
      csh Cvalue.Model.bottom
