Parameter DemandEqIncrSolver.S

include ConstrSys.EqConstrSys
type v
type d
module Var : ConstrSys.VarType with type t = v

Variables must be hashable, comparable, etc.

module Dom : Lattice.S with type t = d

Values must form a lattice.

val sys_change : (v -> d) -> v ConstrSys.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.
