Module Wp.VCS

Provers and Proof Obligations Results

Verification Condition Status

Config

None means current WP option default. Some 0 means prover default.

type config = {
  1. valid : bool;
  2. timeout : float option;
  3. stepout : int option;
  4. memlimit : int option;
}
val current : unit -> config

Current parameters

val default : config

all None

val get_timeout : ?kf:Frama_c_kernel.Kernel_function.t -> smoke:bool -> config -> float

0.0 means no-timeout

val get_stepout : config -> int

0 means no-stepout

val get_memlimit : config -> int

0 means no-memlimit
