module Eval_op:sig
..end
Numeric evaluation. Factored with evaluation in the logic.
val offsetmap_of_v : typ:Cil_types.typ -> Cvalue.V.t -> Cvalue.V_Offsetmap.t
Transformation a value into an offsetmap of size sizeof(typ)
bytes.
val offsetmap_of_loc : Precise_locs.precise_location ->
Cvalue.Model.t -> Cvalue.V_Offsetmap.t Eval.or_bottom
Returns the offsetmap at a precise_location from a state. May raise Abstract_interp.Error_Top.
val wrap_size_t : Cvalue.V.t -> Cvalue.V_Offsetmap.t option
Specialization of the function above for standard types
val wrap_int : Cvalue.V.t -> Cvalue.V_Offsetmap.t option
val wrap_ptr : Cvalue.V.t -> Cvalue.V_Offsetmap.t option
val wrap_double : Cvalue.V.t -> Cvalue.V_Offsetmap.t option
val wrap_float : Cvalue.V.t -> Cvalue.V_Offsetmap.t option
val wrap_long_long : Cvalue.V.t -> Cvalue.V_Offsetmap.t option
val backward_comp_left_from_type : Cil_types.logic_type ->
bool -> Abstract_interp.Comp.t -> Cvalue.V.t -> Cvalue.V.t -> Cvalue.V.t
Reduction of a Cvalue.V.t
by ==
, !=
, >=
, >
, <=
and <
.
backward_comp_left_from_type positive op l r
reduces l
so that the relation l op r
holds. typ
is the type of l
.
val reduce_by_initialized_defined : (Cvalue.V_Or_Uninitialized.t -> Cvalue.V_Or_Uninitialized.t) ->
Locations.location -> Cvalue.Model.t -> Cvalue.Model.t
val apply_on_all_locs : (Locations.location -> 'a -> 'a) -> Locations.location -> 'a -> 'a
apply_all_locs f loc state
folds f
on all the atomic locations
in loc
, provided there are less than plevel
. Useful mainly
when loc
is exact or an over-approximation.
val reduce_by_valid_loc : positive:bool ->
Locations.access ->
Locations.location -> Cil_types.typ -> Cvalue.Model.t -> Cvalue.Model.t
val make_loc_contiguous : Locations.location -> Locations.location
'Simplify' the location if it represents a contiguous zone: instead of multiple offsets with a small size, change it into a single offset with a size that covers the entire range.
