Cil.typeOf, etc reimplemented to raise sensible exceptions instead of printing all errors directly...

val locs : (int, unit) Hashtbl.t

HashSet of line numbers

class countFnVisitor : object ... end

Visitor to count locs appearing inside a fundec.

val fnvis : countFnVisitor
val countLoc : Cil.fundec -> int

Count the number of unique locations appearing in fundec fn. Uses Cilfacade.locs hashtable for intermediate computations

val fundec_return_type : Cil.fundec -> Cil.typ
module StmtH : sig ... end
val stmt_fundecs : Cil.fundec StmtH.t Lazy.t
val pseudo_return_to_fun : Cil.fundec StmtH.t
val find_stmt_fundec : StmtH.key -> Cil.fundec

Find fundec which the stmt is in.

module VarinfoH : sig ... end
val varinfo_fundecs : Cil.fundec VarinfoH.t Lazy.t
val find_varinfo_fundec : VarinfoH.key -> Cil.fundec

Find fundec by the function's varinfo (has the function name and type).

module StringH : sig ... end
val name_fundecs : Cil.fundec StringH.t Lazy.t
val find_name_fundec : StringH.key -> Cil.fundec

Find fundec by the function's name.

type varinfo_role =
  1. | Formal of Cil.fundec
  2. | Local of Cil.fundec
  3. | Function
  4. | Global
val varinfo_roles : varinfo_role VarinfoH.t Lazy.t
val find_varinfo_role : VarinfoH.key -> varinfo_role

Find the role of the varinfo.

val is_varinfo_formal : VarinfoH.key -> bool
val find_scope_fundec : VarinfoH.key -> Cil.fundec option

Find the scope of the varinfo. If varinfo is a local or a formal argument of fundec, then returns Some fundec. If varinfo is a global or a function itself, then returns None.

val original_names : string VarinfoH.t Lazy.t
val find_original_name : VarinfoH.key -> string option

Find the original name (in input source code) of the varinfo. If it was renamed by CIL, then returns the original name before renaming. If it wasn't renamed by CIL, then returns the same name. If it was inserted by CIL (or Goblint), then returns None.
