Module `Biabduction.State`

type t: Internal state

val add_diverging_states : Paths.PathSet.t -> unit: Add diverging states

val get_diverging_states_node : unit -> Paths.PathSet.t: Get the diverging states for the node

val get_diverging_states_proc : unit -> Paths.PathSet.t: Get the diverging states for the procedure

val get_inst_update : IR.PredSymb.path_pos -> Predicates.inst: Get update instrumentation for the current loc

val get_loc_trace : unit -> Absint.Errlog.loc_trace: Get the location trace of the last path seen in symbolic execution

val get_normalized_pre : (IR.Tenv.t -> Prop.normal Prop.t -> Prop.normal Prop.t) -> Prop.normal Prop.t option: return the normalized precondition extracted form the last prop seen, if any the abstraction function is a parameter to get around module dependencies

val get_path : unit -> Paths.Path.t * IR.PredSymb.path_pos option: Get last path seen in symbolic execution

val get_path_pos : unit -> IR.PredSymb.path_pos: Get the last path position seen in symbolic execution

val get_prop_tenv_pdesc : unit -> (Prop.normal Prop.t * IR.Tenv.t * IR.Procdesc.t) option: Get last last prop,tenv,pdesc seen in symbolic execution

val mark_execution_end : IR.Procdesc.Node.t -> unit: Mark the end of symbolic execution of a node

val mark_execution_start : IR.Procdesc.Node.t -> unit: Mark the start of symbolic execution of a node

val mark_instr_fail : exn -> unit: Mark that the execution of the current instruction failed

val mark_instr_ok : unit -> unit: Mark that the execution of the current instruction was OK

val mk_find_duplicate_nodes : IR.Procdesc.t -> IR.Procdesc.Node.t -> IR.Procdesc.NodeSet.t: Create a function to find duplicate nodes. A node is a duplicate of another one if they have the same kind and location and normalized (w.r.t. renaming of let - bound ids) list of instructions.

type log_issue = ?⁠node:IR.Procdesc.Node.t -> ?⁠loc:IBase.Location.t -> ?⁠ltr:Absint.Errlog.loc_trace -> exn -> unit

val process_execution_failures : log_issue -> unit: Process the failures during symbolic execution of a procedure

val reset : unit -> unit: Reset all the global data.

val reset_diverging_states_node : unit -> unit: Reset the diverging states information for the node

val restore_state : t -> unit: Restore the old state.

val save_state : unit -> t: Return the old state, and revert the current state to the initial one.

val set_path : Paths.Path.t -> IR.PredSymb.path_pos option -> unit: Get last path seen in symbolic execution

val set_prop_tenv_pdesc : Prop.normal Prop.t -> IR.Tenv.t -> IR.Procdesc.t -> unit: Set last prop,tenv,pdesc seen in symbolic execution
