Module IR__DecompiledExp

The Smallfoot Intermediate Language: Decompiled Expressions

module F = Stdlib.Format
type t =
| Darray of t * t
| Dbinop of IR.Binop.t * t * t
| Dconst of IR.Const.t
| Dsizeof of IR.Typ.t * t option * IR.Subtype.t
| Dderef of t
| Dfcall of t * t list * IBase.Location.t * IR.CallFlags.t
| Darrow of t * IR.Fieldname.t
| Ddot of t * IR.Fieldname.t
| Dpvar of IR.Pvar.t
| Dpvaraddr of IR.Pvar.t
| Dunop of IR.Unop.t * t
| Dunknown
| Dretcall of t * t list * IBase.Location.t * IR.CallFlags.t

expression representing the result of decompilation

type vpath = t option

Value paths: identify an occurrence of a value in a symbolic heap each expression represents a path, with Dpvar being the simplest one

val pp : F.formatter -> t -> unit
val to_string : t -> string

convert to a string

val pp_vpath : IStdlib.Pp.env -> F.formatter -> vpath -> unit

Pretty print a value path

val has_tmp_var : t -> bool

return true if dexp contains a temporary pvar
