val unchanged_to_change_status : bool -> change_status

Given a boolean that indicates whether the code object is identical to the previous version, returns the corresponding change_status

val empty_rename_mapping : rename_mapping

val performRenames : renamesOnSuccess -> unit

val addOldGlobals : 'a -> global_col -> (change_info * ('b VarinfoMap.t * 'c)) -> change_info * ('b VarinfoMap.t * 'c)

Given an (optional) equality function between Cil.globals, an old and a new Cil.file, this function computes a change_info, which describes which globals are changed, unchanged, removed and added.
