Module CurrentVarDemandEqConstrSys.S

include module type of struct include S end
include EqConstrSys
type v = S.v
type d = S.d
module Var = S.Var

Variables must be hashable, comparable, etc.

module Dom = S.Dom

Values must form a lattice.

val sys_change : (v -> d) -> v sys_change_info

Compute incremental constraint system change from old solution.

val postmortem : v -> v list

List of unknowns that should be queried again when the argument unknown has shrunk to bot, to eagerly trigger (analysis-time!) abstract garbage collection idependently of reach-based pruning at the end.
