Class type

Signatures for analyzers, analysis specifications, and result output.

module GU = Goblintutil
module M = Messages
type fundecs = Cil.fundec list * Cil.fundec list * Cil.fundec list

Analysis starts from lists of functions: start functions, exit functions, and * other functions.

module type VarType = sig ... end
module Var : sig ... end
module VarF (LD : Printable.S) : sig ... end
exception Deadcode
module Dom (LD : Lattice.S) : sig ... end

Dom (D) produces D lifted where bottom means dead-code

exception Ctx_failure of string

Failure from ctx, e.g. global initializer

val ctx_failwith : string -> 'a
val ask_of_ctx : ('a, 'b, 'c) ctx -> Queries.ask

Convert ctx to Queries.ask.

module type MonSystem = sig ... end

A side-effecting system.

module type EqConstrSys = MonSystem with type 'a m := 'a option

Any system of side-effecting equations over lattices.

module type GlobConstrSys = sig ... end

A side-effecting system with globals.

module type GenericEqBoxIncrSolverBase = functor (S : EqConstrSys) -> functor (H : Prelude.Hashtbl.S with type key = S.v) -> sig ... end

A solver is something that can translate a system into a solution (hash-table). Incremental solver has data to be marshaled.

module type IncrSolverArg = sig ... end

(Incremental) solver argument, indicating which postsolving should be performed by the solver.

An incremental solver takes the argument about postsolving.

module type GenericEqBoxSolver = functor (S : EqConstrSys) -> functor (H : Prelude.Hashtbl.S with type key = S.v) -> sig ... end

A solver is something that can translate a system into a solution (hash-table)

A solver is something that can translate a system into a solution (hash-table)

module ResultType2 (S : Spec) : sig ... end
module DefaultSpec : sig ... end

Relatively safe default implementations of some boring Spec functions.
