Module `Goblint_lib.Cilfacade`

Helpful functions for dealing with Cil.

module E = GoblintCil.Errormsg

module GU = Goblintutil

include module type of struct include Cilfacade0 end

Cilfacade functions to avoid dependency cycles.

val get_labelLoc : GoblintCil.label -> GoblintCil.location

val get_labelsLoc : GoblintCil.label list -> GoblintCil.Cil.location

Following functions are similar to Cil versions, but return expression location instead of entire statement location, where possible.

val get_instrLoc : GoblintCil.instr -> GoblintCil.location

Get expression location for Cil.instr.

Get expression location for Cil.stmt.

val ptrdiff_ikind : unit -> GoblintCil.ikind

val ptr_ikind : unit -> GoblintCil.ikind

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 : GoblintCil.fundec -> int

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

val fundec_return_type : GoblintCil.fundec -> GoblintCil.typ

module StmtH : sig ... end

val stmt_fundecs : GoblintCil.fundec StmtH.t ResettableLazy.t

val pseudo_return_to_fun : GoblintCil.fundec StmtH.t

val find_stmt_fundec : StmtH.key -> GoblintCil.fundec

Find fundec which the stmt is in.

module VarinfoH : sig ... end

val varinfo_fundecs : GoblintCil.fundec VarinfoH.t ResettableLazy.t

val find_varinfo_fundec : VarinfoH.key -> GoblintCil.fundec

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

module StringH : sig ... end

val name_fundecs : GoblintCil.fundec StringH.t ResettableLazy.t

val find_name_fundec : StringH.key -> GoblintCil.fundec

Find fundec by the function's name.

type varinfo_role =

| Formal of GoblintCil.fundec
| Local of GoblintCil.fundec
| Function
| Global

val varinfo_roles : varinfo_role VarinfoH.t ResettableLazy.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 -> GoblintCil.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 ResettableLazy.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.

val reset_lazy : unit -> unit

val stmt_pretty_short : unit -> GoblintCil.stmt -> GoblintCil__.Pretty.doc

val add_function_declarations : GoblintCil.Cil.file -> unit

Given a Cil.file, reorders its globals, inserts function declarations before function definitions. This function may be used after a code transformation to ensure that the order of globals yields a compilable program.
