Module `Goblint_lib.Constraints`

Construction of a constraint system from an analysis specification and CFGs. Transformatons of analysis specifications as functors.

module M = Messages

module HashconsLifter
  (S : Analyses.Spec) : 
  Analyses.Spec
    with module D = Lattice.HConsed(S.D)
     and module G = S.G
     and module C = S.C

Lifts a Spec so that the domain is Hashconsd

module HashconsContextLifter
  (S : Analyses.Spec) : 
  Analyses.Spec
    with module D = S.D
     and module G = S.G
     and module C = Printable.HConsed(S.C)

Lifts a Spec so that the context is Hashconsd.

module LevelSliceLifter
  (S : Analyses.Spec) : 
  Analyses.Spec
    with module D = Lattice.Prod(S.D)(Lattice.Reverse(IntDomain.Lifted))
     and module G = S.G

If dbg.slice.on, stops entering functions after dbg.slice.n levels.

module LimitLifter (S : Analyses.Spec) : sig ... end

Limits the number of widenings per node.

module WidenContextLifterSide (S : Analyses.Spec) : sig ... end

module Var2
  (LV : Analyses.VarType)
  (GV : Analyses.VarType) : 
  Analyses.VarType with type t = [ `L of LV.t | `G of GV.t ]

module FromSpec
  (S : Analyses.Spec)
  (Cfg : MyCFG.CfgBackward)
  (I : Increment) : 
  sig ... end

The main point of this file---generating a GlobConstrSys from a Spec.

module EqIncrSolverFromEqSolver
  (Sol : Analyses.GenericEqSolver) : 
  Analyses.GenericEqIncrSolver

Convert a non-incremental solver into an "incremental" solver. It will solve from scratch, perform standard postsolving and have no marshal data.

module EqConstrSysFromGlobConstrSys
  (S : Analyses.GlobConstrSys) : 
  Analyses.EqConstrSys
    with type v = Var2(S.LVar)(S.GVar).t
     and type d = Lattice.Lift2(S.G)(S.D)(Printable.DefaultNames).t
     and module Var = Var2(S.LVar)(S.GVar)
     and module Dom = Lattice.Lift2(S.G)(S.D)(Printable.DefaultNames)

Translate a GlobConstrSys into a EqConstrSys

module GlobConstrSolFromEqConstrSolBase
  (S : Analyses.GlobConstrSys)
  (LH : Batteries.Hashtbl.S with type key = S.LVar.t)
  (GH : Batteries.Hashtbl.S with type key = S.GVar.t)
  (VH : Batteries.Hashtbl.S with type key = Var2(S.LVar)(S.GVar).t) : 
  sig ... end

Splits a EqConstrSys solution into a GlobConstrSys solution with given Hashtbl.S for the EqConstrSys.

module GlobConstrSolFromEqConstrSol
  (S : Analyses.GlobConstrSys)
  (LH : Batteries.Hashtbl.S with type key = S.LVar.t)
  (GH : Batteries.Hashtbl.S with type key = S.GVar.t) : 
  sig ... end

Splits a EqConstrSys solution into a GlobConstrSys solution.

module GlobSolverFromEqSolver
  (Sol : Analyses.GenericEqIncrSolverBase)
  (S : Analyses.GlobConstrSys)
  (LH : Batteries.Hashtbl.S with type key = S.LVar.t)
  (GH : Batteries.Hashtbl.S with type key = S.GVar.t) : 
  sig ... end

Transforms a GenericEqIncrSolver into a GenericGlobSolver.

module PathSensitive2
  (Spec : Analyses.Spec) : 
  Analyses.Spec
    with module G = Spec.G
     and module C = Spec.C
     and module V = Spec.V

Add path sensitivity to a analysis
