Module `HilExp.AccessExpression`

val of_id : IR.Ident.t -> IR.Typ.t -> access_expression
val base : AccessPath.base -> access_expression
val field_offset : access_expression -> IR.Fieldname.t -> access_expression
val array_offset : access_expression -> IR.Typ.t -> t option -> access_expression
val dereference : access_expression -> access_expression: guarantees that we never build Dereference (AddressOf t) expressions: these become t

val address_of : access_expression -> access_expression option: address_of doesn't always make sense, eg address_of (Dereference t) is None

val address_of_base : AccessPath.base -> access_expression
val to_access_path : access_expression -> AccessPath.t
val get_base : access_expression -> AccessPath.base
val replace_base : remove_deref_after_base:bool -> AccessPath.base -> access_expression -> access_expression
val is_base : access_expression -> bool
val is_return_var : access_expression -> bool
val get_typ : access_expression -> IR.Tenv.t -> IR.Typ.t option
val pp : Stdlib.Format.formatter -> access_expression -> unit
val equal : access_expression -> access_expression -> bool
val to_accesses : access_expression -> access_expression * t option Access.t list: return the base and a list of accesses equivalent to the input expression

val add_access : access_expression -> t option Access.t -> access_expression option
val truncate : access_expression -> (access_expression * t option Access.t) option: remove and return the prefix and the last access of the expression if it's a base; otherwise return None

val append : onto:access_expression -> access_expression -> access_expression option: append ~onto y replaces the base of y with onto itself; this makes sense if no Dereference (AddressOf _) instances are introduced

type nonrec t = private access_expression = | Base of AccessPath.base | FieldOffset of access_expression * IR.Fieldname.t | ArrayOffset of access_expression * IR.Typ.t * t option | AddressOf of access_expression | Dereference of access_expression
