Module Pulselib.PulseAbductiveDomain

module F = Stdlib.Format
module BaseAddressAttributes = PulseBaseAddressAttributes
module BaseDomain = PulseBaseDomain
module BaseMemory = PulseBaseMemory
module BaseStack = PulseBaseStack
module type BaseDomainSig = sig ... end

signature common to the "normal" Domain, representing the post at the current program point, and the inverted PreDomain, representing the inferred pre-condition

module PostDomain : BaseDomainSig

The post abstract state at each program point, or current state.

module PreDomain : BaseDomainSig

The inferred pre-condition at each program point, biabduction style.

type t = private {
post : PostDomain.t;

state at the current program point

pre : PreDomain.t;

inferred pre at the current program point

skipped_calls : PulseBasicInterface.SkippedCalls.t;

set of skipped calls

path_condition : PulseBasicInterface.PathCondition.t;

arithmetic facts

}

biabduction-style pre/post state + skipped calls

val leq : lhs:t -> rhs:t -> bool
val pp : Stdlib.Format.formatter -> t -> unit
val mk_initial : IR.Procdesc.t -> t
val get_pre : t -> BaseDomain.t
val get_post : t -> BaseDomain.t
module Stack : sig ... end

stack operations like BaseStack but that also take care of propagating facts to the precondition

module Memory : sig ... end

memory operations like BaseMemory but that also take care of propagating facts to the precondition

module AddressAttributes : sig ... end

attribute operations like BaseAddressAttributes but that also take care of propagating facts to the precondition

val is_local : IR.Var.t -> t -> bool
val find_post_cell_opt : PulseBasicInterface.AbstractValue.t -> t -> BaseDomain.cell option
val discard_unreachable : t -> t * Pulselib.PulseBasicInterface.AbstractValue.Set.t * PulseBasicInterface.AbstractValue.t list

garbage collect unreachable addresses in the state to make it smaller and return the new state, the live addresses, and the discarded addresses that used to have attributes attached

val add_skipped_call : IR.Procname.t -> PulseBasicInterface.Trace.t -> t -> t
val add_skipped_calls : PulseBasicInterface.SkippedCalls.t -> t -> t
val set_path_condition : PulseBasicInterface.PathCondition.t -> t -> t
val of_post : IR.Procdesc.t -> t -> t
val set_post_edges : PulseBasicInterface.AbstractValue.t -> BaseMemory.Edges.t -> t -> t

directly set the edges for the given address, bypassing abduction altogether

val set_post_cell : (PulseBasicInterface.AbstractValue.t * PulseBasicInterface.ValueHistory.t) -> BaseDomain.cell -> IBase.Location.t -> t -> t

directly set the edges and attributes for the given address, bypassing abduction altogether
