Module InferModules.Attribute

Attribute manipulation in Propositions (i.e., Symbolic Heaps)

val is_pred : InferIR.Sil.atom ‑> bool

Check whether an atom is used to mark an attribute

val add : InferIR.Tenv.t ‑> ?⁠footprint:bool ‑> ?⁠polarity:bool ‑> Prop.normal Prop.t ‑> InferIR.PredSymb.t ‑> InferIR.Exp.t list ‑> Prop.normal Prop.t

Add an attribute associated to the argument expressions

val add_or_replace : InferIR.Tenv.t ‑> Prop.normal Prop.t ‑> InferIR.Sil.atom ‑> Prop.normal Prop.t

Replace an attribute associated to the expression, and call the given function with new and old attributes if they changed.

val get_all : 'a Prop.t ‑> InferIR.Sil.atom list

Get all the attributes of the prop

val get_for_exp : InferIR.Tenv.t ‑> 'a Prop.t ‑> InferIR.Exp.t ‑> InferIR.Sil.atom list

Remove an attribute

val remove_for_attr : InferIR.Tenv.t ‑> Prop.normal Prop.t ‑> InferIR.PredSymb.t ‑> Prop.normal Prop.t

Remove all attributes for the given attr

val remove_resource : InferIR.Tenv.t ‑> InferIR.PredSymb.res_act_kind ‑> InferIR.PredSymb.resource ‑> Prop.normal Prop.t ‑> Prop.normal Prop.t
