Use the stack and heap to evaluate the given expression down to an abstract address representing its value.

Return an error state if it traverses some known invalid address or if the end destination is known to be invalid.

val eval_deref : InferBase.Location.t -> InferIR.Exp.t -> t -> (t * InferModules.PulseDomain.AddrTracePair.t) access_result: Like eval but evaluates *exp.

val eval_access : InferBase.Location.t -> InferModules.PulseDomain.AddrTracePair.t -> InferModules.PulseDomain.Memory.Access.t -> t -> (t * InferModules.PulseDomain.AddrTracePair.t) access_result: Like eval but starts from an address instead of an expression, checks that it is valid, and if so dereferences it according to the access.

val havoc_deref : InferBase.Location.t -> InferModules.PulseDomain.AddrTracePair.t -> InferModules.PulseDomain.ValueHistory.t -> t -> t access_result
val havoc_field : InferBase.Location.t -> InferModules.PulseDomain.AddrTracePair.t -> InferIR.Typ.Fieldname.t -> InferModules.PulseDomain.ValueHistory.t -> t -> t access_result
val realloc_var : InferIR.Var.t -> InferBase.Location.t -> t -> t

val write_deref : InferBase.Location.t -> ref:InferModules.PulseDomain.AddrTracePair.t -> obj:InferModules.PulseDomain.AddrTracePair.t -> t -> t access_result: write the edge ref --*--> obj

val invalidate : InferBase.Location.t -> InferModules.PulseDomain.Invalidation.t InferModules.PulseDomain.InterprocAction.t -> InferModules.PulseDomain.AddrTracePair.t -> t -> t access_result: record that the address is invalid

val invalidate_deref : InferBase.Location.t -> InferModules.PulseDomain.Invalidation.t InferModules.PulseDomain.InterprocAction.t -> InferModules.PulseDomain.AddrTracePair.t -> t -> t access_result: record that what the address points to is invalid

val invalidate_array_elements : InferBase.Location.t -> InferModules.PulseDomain.Invalidation.t InferModules.PulseDomain.InterprocAction.t -> InferModules.PulseDomain.AddrTracePair.t -> t -> t access_result: record that all the array elements that address points to is invalid

val shallow_copy : InferBase.Location.t -> InferModules.PulseDomain.AddrTracePair.t -> t -> (t * AbstractAddress.t) access_result: returns the address of a new cell with the same edges as the original

val remove_vars : InferIR.Var.t list -> InferBase.Location.t -> t -> t
val check_address_escape : InferBase.Location.t -> InferIR.Procdesc.t -> AbstractAddress.t -> InferModules.PulseDomain.ValueHistory.t -> t -> t access_result
val call : caller_summary:InferModules.Summary.t -> InferBase.Location.t -> InferIR.Typ.Procname.t -> ret:(InferIR.Ident.t * InferIR.Typ.t) -> actuals:((AbstractAddress.t * InferModules.PulseDomain.ValueHistory.t) * InferIR.Typ.t) list -> t -> t list access_result: perform an interprocedural call: apply the summary for the call proc name passed as argument if it exists
