To select a statement.
val select_stmt_ctrl : set ->
spare:bool ->
Cil_types.stmt -> Cil_types.kernel_function -> set

eval:Cil_types.stmt -> Cil_types.kernel_function -> set
To select rw accesses to lvalues (given as a string) related to a
statement.
Variable names used in the sets of strings ~rd

are relative
to the function scope.
The interpretation of the address of the lvalues is
done just before the execution of the statement ~eval
.
The selection preserves the ~rd
and ~wr
accesses contained into
the statement ki
.
Note: add also a transparent selection on the whole statement.
Change in Magnesium-20151001: argument ~scope
removed.

To select lvalues (given as string) related to a statement.
Variable names used in the sets of strings ~rd
and ~wr
are relative
to the function scope.
The interpretation of the address of the lvalue is
done just before the execution of the statement ~eval
.
The selection preserve the value of these lvalues before or
after (c.f. boolean ~before

To select nodes of the PDG
- if
is_ctrl_mark m
,
propagate ctrl_mark on ctrl dependencies
- if
is_addr_mark m
,
propagate addr_mark on addr dependencies
- if
is_data_mark m
,
propagate data_mark on data dependencies
- mark the node with a spare_mark and propagate so that
the dependencies that were not selected yet will be marked spare.
Not for casual users and not journalized
val get_function : t -> Cil_types.kernel_function
May be used to get the function related to an internal selection.
val merge_internal : t -> t -> t
val add_to_selects_internal : t -> set -> set
val iter_selects_internal : (t -> unit) -> set -> unit
val fold_selects_internal : ('a -> t -> 'a) -> 'a -> set -> 'a
val select_stmt_internal : Cil_types.kernel_function ->
?select:t ->
Cil_types.stmt -> Slicing.Api.Mark.t -> t
May be used to select a statement :
- if
is_ctrl_mark m
,
propagates ctrl_mark on ctrl dependencies of the statement
- if
is_addr_mark m
,
propagates addr_mark on addr dependencies of the statement
- if
is_data_mark m
,
propagates data_mark on data dependencies of the statement
- otherwise, marks the node with a spare_mark and propagate so that
the dependencies that were not selected yet will be marked spare.
When the statement is a call, its functional inputs/outputs are
also selected (The call is still selected even it has no output).
When the statement is a composed one (block, if, etc...),
all the sub-statements are selected.
Raises SlicingTypes.NoPdg
when there is no PDG for the
kernel_function
(related to
PdgTypes.Pdg.is_top
).
val select_label_internal : Cil_types.kernel_function ->
?select:t ->
Cil_datatype.Logic_label.t -> Slicing.Api.Mark.t -> t
May be used to select a label.
val select_min_call_internal : Cil_types.kernel_function ->
?select:t ->
Cil_types.stmt -> Slicing.Api.Mark.t -> t
May be used to select a statement call without its
inputs/outputs so that it doesn't select the statements computing the
inputs of the called function as
select_stmt_internal
would do.
RaisesInvalid_argument
when the stmt
isn't a call.
SlicingTypes.NoPdg
when there is no PDG for the
kernel_function
(related to PdgTypes.Pdg.is_top
).
val select_stmt_zone_internal : Cil_types.kernel_function ->
?select:t ->
Cil_types.stmt ->
before:bool -> Locations.Zone.t -> Slicing.Api.Mark.t -> t
May be used to select a zone value at a program point.
Raises SlicingTypes.NoPdg
when there is no PDG for the
kernel_function
(related to PdgTypes.Pdg.is_top
).
val select_zone_at_entry_point_internal : Cil_types.kernel_function ->
?select:t ->
Locations.Zone.t -> Slicing.Api.Mark.t -> t
May be used to select a zone value at the beginning of a function.
For a defined function, it is similar to select_stmt_zone_internal
with the initial statement, but it can also be used for undefined
functions.
Raises SlicingTypes.NoPdg
when there is no PDG for the
kernel_function
(related to PdgTypes.Pdg.is_top
).
val select_zone_at_end_internal : Cil_types.kernel_function ->
?select:t ->
Locations.Zone.t -> Slicing.Api.Mark.t -> t
May be used to select a zone value at the end of a function.
For a defined function, it is similar to select_stmt_zone_internal
with the return statement, but it can also be used for undefined
functions.
Raises SlicingTypes.NoPdg
when there is no PDG for the
kernel_function
(related to PdgTypes.Pdg.is_top
).
val select_modified_output_zone_internal : Cil_types.kernel_function ->
?select:t ->
Locations.Zone.t -> Slicing.Api.Mark.t -> t
May be used to select the statements that modify the
given zone considered as in output.
Be careful that it is NOT the same as selecting the zone at the end!
(the 'undef' zone is not propagated...).
val select_stmt_ctrl_internal : Cil_types.kernel_function ->
?select:t -> Cil_types.stmt -> t
May be used to select a statement reachability :
Only propagate a ctrl_mark on the statement control dependencies.
Raises SlicingTypes.NoPdg
when there is no PDG for the
kernel_function
(related to PdgTypes.Pdg.is_top
).
