Module Globals.Vars

Globals variables. The AST should be computed before using this module (cf. Ast.compute).

Getters

val find_from_astinfo : string -> Cil_types.localisation -> Cil_types.varinfo

Finds a variable from its vname according to its localisation (which might be a local). If you wish to search for a symbol according to its original name in the source code and the syntactic scope in which it should appear, use Globals.Syntactic_search instead.

  • raises Not_found

    if no such variable exists.

val get_astinfo : Cil_types.varinfo -> string * Cil_types.localisation

Linear in the number of locals and formals of the program.

Iterators

val iter : ( Cil_types.varinfo -> Cil_types.initinfo -> unit ) -> unit
val fold : ( Cil_types.varinfo -> Cil_types.initinfo -> 'a -> 'a ) -> 'a -> 'a
val iter_in_file_order : ( Cil_types.varinfo -> Cil_types.initinfo -> unit ) -> unit

The next four iterators iter on all global variables present in the AST, following the order in which they are declared/defined. The only exception is for variables that are both declared and defined. In this case, the declarations are skipped altogether.

Setters

Functions of this section should not be called by casual users.

exception AlreadyExists of Cil_types.varinfo * Cil_types.initinfo
  • raises AlreadyExists

    if the given varinfo is already registered.

val remove : Cil_types.varinfo -> unit

Removes the given varinfo, which must have already been removed from the AST. Warning: this is very dangerous.

  • since 18.0-Argon
val add_decl : Cil_types.varinfo -> unit
  • raises AlreadyExists

    if the given varinfo is already registered.
