Module `InferModules.SymExec`

val declare_locals_and_ret : InferIR.Tenv.t -> InferIR.Procdesc.t -> Prop.normal Prop.t -> Prop.normal Prop.t: Symbolic execution of the declaration of locals and return value.

val node : (exn -> unit) -> Exe_env.t -> InferIR.Tenv.t -> Summary.t -> ProcCfg.Exceptional.t -> ProcCfg.Exceptional.Node.t -> Paths.PathSet.t -> Paths.PathSet.t: Symbolic execution of the instructions of a node, lifted to sets of propositions.

val instrs : ?⁠mask_errors:bool -> Exe_env.t -> InferIR.Tenv.t -> Summary.t -> InferIR.Instrs.not_reversed_t -> (Prop.normal Prop.t * Paths.Path.t) list -> (Prop.normal Prop.t * Paths.Path.t) list: Symbolic execution of a sequence of instructions. If errors occur and mask_errors is true, just treat as skip.

val diverge : Prop.normal Prop.t -> Paths.Path.t -> (Prop.normal Prop.t * Paths.Path.t) list: Symbolic execution of the divergent pure computation.

val proc_call : ?⁠dynamic_dispatch:InferBase.EventLogger.dynamic_dispatch -> Exe_env.t -> Summary.t -> Builtin.t
val unknown_or_scan_call : is_scan:bool -> reason:string -> InferIR.Typ.t -> InferIR.Annot.Item.t -> Builtin.t
val check_variadic_sentinel : ?⁠fails_on_nil:bool -> int -> (int * int) -> Builtin.t
val check_arith_norm_exp : InferIR.Tenv.t -> InferIR.Typ.Procname.t -> InferIR.Exp.t -> Prop.normal Prop.t -> InferIR.Exp.t * Prop.normal Prop.t: Check for arithmetic problems and normalize an expression.

val prune : InferIR.Tenv.t -> positive:bool -> InferIR.Exp.t -> Prop.normal Prop.t -> Propset.t
