Regular interface for BIL statements

type t = Bil.stmt
class state : object ... end

All visitors provide some information about the current position of the visitor

class 'a visitor : object ... end

Visitor. Visits AST providing lots of hooks.

class 'a finder : object ... end

A visitor with a shortcut. Finder is a specialization of a visitor, that uses return as its folding argument. At any time you can stop the traversing by calling return function of the provided argument (which is by itself is a record with one field - a function accepting argument of type 'a option).

class mapper : object ... end

AST transformation. mapper allows one to map AST, performing some limited amount of transformations on it. Mapper provides extra flexibility by mapping stmt to stmt list, thus allowing to remove statements from the output (by mapping to empty list) or to map one statement to several. This is particularly useful when you map if or while statements.

constant_folder is a class that implements the fold_consts

val fold : 'a visitor -> init:'a -> t -> 'a

fold ~init visitor stmt folds a stmt with a visitor. See Bil.fold and Exp.fold for more details.

val iter : unit visitor -> t -> unit

iter visitor stmt iters over a stmt with a visitor. See Bil.iter and Exp.iter for more details.

val map : mapper -> t list -> t list

map mapper bil applies mapper to the program bil

val find : 'a finder -> t -> 'a option

find finder stmt performs a lookup into the Bil statement. See Bil.find and Exp.find for more details.

val exists : unit finder -> t -> bool

exists finder stmt is true iff find finder stmt <> None. See Bil.exists and Exp.exists for more details.

val is_referenced : var -> t -> bool

is_referenced x stmt is true is x is used in the stmt in any place other then right hand side of the assignment. E.g., is_referenced x Bil.(x := var x) is true, but is_referenced x Bil.(x := var y) is false. see Bil.is_referenced for more details.

val fixpoint : (t -> t) -> t -> t

fixpoint f x applies transformation f until it reaches fixpoint. See Bil.fixpoint and Exp.fixpoint

val free_vars : t -> Var.Set.t

free_vars stmt returns a set of all unbound variables, that occurs in the stmt.

val eval : t list -> Bili.context as 'a -> 'a

eval prog eval BIL program under given context. Returns the context which contains all effects of computations.
