val eval : IBase.Location.t -> IR.Exp.t -> t -> (t * (PulseBasicInterface.AbstractValue.t * PulseBasicInterface.ValueHistory.t)) access_result
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 prune : IBase.Location.t -> condition:IR.Exp.t -> t -> t access_result
val eval_deref : IBase.Location.t -> IR.Exp.t -> t -> (t * (PulseBasicInterface.AbstractValue.t * PulseBasicInterface.ValueHistory.t)) access_result
Like
eval
but evaluates*exp
.
val eval_access : IBase.Location.t -> (PulseBasicInterface.AbstractValue.t * PulseBasicInterface.ValueHistory.t) -> Pulselib.PulseDomainInterface.BaseMemory.Access.t -> t -> (t * (PulseBasicInterface.AbstractValue.t * PulseBasicInterface.ValueHistory.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 invalidate : IBase.Location.t -> PulseBasicInterface.Invalidation.t -> (PulseBasicInterface.AbstractValue.t * PulseBasicInterface.ValueHistory.t) -> t -> t access_result
record that the address is invalid

val invalidate_access : IBase.Location.t -> PulseBasicInterface.Invalidation.t -> (PulseBasicInterface.AbstractValue.t * PulseBasicInterface.ValueHistory.t) -> Pulselib.PulseDomainInterface.BaseMemory.Access.t -> t -> t access_result
record that what the address points via the access to is invalid
val invalidate_array_elements : IBase.Location.t -> PulseBasicInterface.Invalidation.t -> (PulseBasicInterface.AbstractValue.t * PulseBasicInterface.ValueHistory.t) -> t -> t access_result
record that all the array elements that address points to is invalid
val shallow_copy : IBase.Location.t -> (PulseBasicInterface.AbstractValue.t * PulseBasicInterface.ValueHistory.t) -> t -> (t * (PulseBasicInterface.AbstractValue.t * PulseBasicInterface.ValueHistory.t)) access_result
returns the address of a new cell with the same edges as the original
val get_dynamic_type_unreachable_values : IR.Var.t list -> t -> (IR.Var.t * IR.Typ.Name.t) list
Given a list of variables, computes the unreachable values if the variables were removed from the stack, then return the dynamic types of those values if they are available
val remove_vars : IR.Var.t list -> IBase.Location.t -> t -> t access_result
val check_address_escape : IBase.Location.t -> IR.Procdesc.t -> PulseBasicInterface.AbstractValue.t -> PulseBasicInterface.ValueHistory.t -> t -> t access_result

perform an interprocedural call: apply the summary for the call proc name passed as argument if it exists
val unknown_call : IBase.Location.t -> PulseBasicInterface.CallEvent.t -> ret:(IR.Ident.t * IR.Typ.t) -> actuals:((PulseBasicInterface.AbstractValue.t * PulseBasicInterface.ValueHistory.t) * IR.Typ.t) list -> formals_opt:(IR.Pvar.t * IR.Typ.t) list option -> t -> t
performs a call to a function with no summary by optimistically havoc'ing the by-ref actuals and the return value as appropriate
