map_and_merge f m1 m2
maps f
on values in m1
and add_exact
all elements of the mapped m1
to m2

val uninitialize : Cil_types.varinfo list -> t -> t
binds the given variables to bottom, keeps the other unchanged.
val fold : (Locations.Zone.t -> bool * y -> 'a -> 'a) ->
t -> 'a -> 'a
fold f m
folds a function f
on bindings in m
. Each binding
associates to a zone a boolean representing the possibility that the
zone was not modified, and a value of type y. May raise
Cannot_fold
.
val fold_base : (Base.t -> LOffset.t -> 'a -> 'a) ->
t -> 'a -> 'a
val fold_fuse_same : (Locations.Zone.t -> bool * y -> 'a -> 'a) ->
t -> 'a -> 'a
Same behavior as
fold
, except if two disjoint ranges
r1
and
r2
of
a given base are mapped to the same value and boolean. In this
case,
fold
will call its argument
f
on
r1
, then on
r2
.
fold_fuse_same
will call it directly on
r1 U r2
, where U
is the join on sets of intervals.
May raise Cannot_fold
.
val map2 : ((bool * y) option ->
(bool * y) option ->
bool * y) ->
t -> t -> t
like for fold
, the boolean in bool * y
indicates if it is possible
that the zone was not modified
val copy_paste : f:(bool * y ->
bool * y) ->
Locations.location -> Locations.location -> t -> t
This function takes a function f
to be applied to each bit of
the read slice. Otherwise, it has the same specification as
copy_paste
for Location_map.copy_paste
. It may raise
Bitwise_cannot_copy
.
Precondition : the two locations must have the same size
val clear_caches : unit -> unit
Clear the caches local to this module. Beware that they are not
project-aware, and that you must call them at every project switch.
