Module `InferBase__SymOp`

Symbolic Operations and Failures: the units in which analysis work is measured

type t: Internal state of the module

val check_wallclock_alarm : unit -> unit: if the wallclock alarm has expired, raise a timeout exception

val get_remaining_wallclock_time : unit -> float: Return the time remaining before the wallclock alarm expires

val get_timeout_seconds : unit -> float option: Timeout in seconds for each function

val get_total : unit -> int: Return the total number of symop's since the beginning

val pay : unit -> unit: Count one symop

val reset_total : unit -> unit: Reset the total number of symop's

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

val save_state : keep_symop_total:bool -> t: Return the old state, and revert the current state to the initial one. If keep_symop_total is true, share the total counter.

val set_alarm : unit -> unit: Reset the counter and activate the alarm

val set_wallclock_alarm : float -> unit: Set the wallclock alarm checked at every pay()

val set_wallclock_timeout_handler : (unit -> unit) -> unit: set the handler for the wallclock timeout

val unset_alarm : unit -> unit: De-activate the alarm

val unset_wallclock_alarm : unit -> unit: Unset the wallclock alarm checked at every pay()

type failure_kind = | FKtimeout max time exceeded | FKsymops_timeout of int max symop's exceeded | FKrecursion_timeout of int max recursion level exceeded | FKcrash of string uncaught exception or failed assertion

exception Analysis_failure_exe of failure_kind: Timeout exception

val exn_not_failure : exn -> bool: check that the exception is not a timeout exception

val try_finally : f:(unit -> 'a) -> finally:(unit -> unit) -> 'a: try_finally ~f ~finally executes f and then finally even if f raises an exception. Assuming that finally () terminates quickly Analysis_failure_exe exceptions are handled correctly. In particular, an exception raised by f () is delayed until finally () finishes, so finally () should return reasonably quickly.
