Module Fixpoint

module Fixpoint: sig .. end
Fixpoint computation implemented using the work list algorithm. This module makes writing data-flow analysis easy.

module type G = sig .. end
Minimal graph signature for work list algorithm
type direction = 
| Forward
| Backward (*Type of an analysis*)
module type Analysis = sig .. end
module Make: 
functor (G : G) ->
functor (A : Analysis with type cfg = G.t with type label = G.E.label with type vertex = G.V.t) -> sig .. end
