Module Api.SelectSource

Slicing selections.

Internal selection.

For dynamic type checking.

Set of colored selections.

For dynamic type checking.

Selectors.

Sourceval empty_selects : set

Empty selection.

Statement selectors.

To select a statement.

To select a statement reachability. Note: add also a transparent selection on the whole statement.

To select rw accesses to lvalues (given as string) related to a statement. Variables of ~rd and ~wr string are bounded relatively to the whole scope of the function. The interpretation of the address of the lvalues is done just before the execution of the statement ~eval. The selection preserve the ~rd and ~wr accesses contained into the statement ki. Note: add also a transparent selection on the whole statement.

To select lvalues (given as string) related to a statement. Variables of lval_str string are bounded relatively to the whole scope of the function. 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) the statement ki. Note: add also a transparent selection on the whole statement.

To select a zone value related to a statement. Note: add also a transparent selection on the whole statement.

To select a predicate value related to a statement. Note: add also a transparent selection on the whole statement.

To select a predicate value related to a statement. Note: add also a transparent selection on the whole statement.

To select the annotations related to a statement. Note: add also a transparent selection on the whole statement.

Sourceval select_stmt_annots : set -> Mark.t -> spare:bool -> threat:bool -> user_assert:bool -> slicing_annot:bool -> loop_inv:bool -> loop_var:bool -> Frama_c_kernel.Cil_datatype.Stmt.t -> Frama_c_kernel.Cil_types.kernel_function -> set

To select the annotations related to a statement. Note: add also a transparent selection on the whole statement.

Function selectors.

To select rw accesses to lvalues (given as a string) related to a function. Variables of ~rd and ~wr string are bounded relatively to the whole scope of the function. The interpretation of the address of the lvalues is done just before the execution of the statement ~eval. The selection preserve the value of these lvalues into the whole project.

To select lvalues (given as a string) related to a function. Variables of lval_str string are bounded relatively to the scope of the first statement of kf. The interpretation of the address of the lvalues is done just before the execution of the first statement kf. The selection preserve the value of these lvalues before execution of the return statement.

To select an output zone related to a function.

Sourceval select_func_return : set -> spare:bool -> Frama_c_kernel.Cil_types.kernel_function -> set

To select the function result (returned value).

Sourceval select_func_calls_to : set -> spare:bool -> Frama_c_kernel.Cil_types.kernel_function -> set

To select every calls to the given function, i.e. the call keeps its semantics in the slice.

Sourceval select_func_calls_into : set -> spare:bool -> Frama_c_kernel.Cil_types.kernel_function -> set

To select every calls to the given function without the selection of its inputs/outputs.

Sourceval select_func_annots : set -> Mark.t -> spare:bool -> threat:bool -> user_assert:bool -> slicing_annot:bool -> loop_inv:bool -> loop_var:bool -> Frama_c_kernel.Cil_types.kernel_function -> set

To select the annotations related to a function.

Pdg selectors.

Internal use only

The function related to an internal selection.

Sourceval merge_internal : t -> t -> t

The function related to an internal selection.

Sourceval add_to_selects_internal : t -> set -> set
Sourceval iter_selects_internal : (t -> unit) -> set -> unit
Sourceval fold_selects_internal : ('a -> t -> 'a) -> 'a -> set -> 'a

Internally used to select a statement :

  • if is_ctrl_mark m, propagate ctrl_mark on ctrl dependencies of the statement
  • if is_addr_mark m, propagate addr_mark on addr dependencies of the statement
  • if is_data_mark m, propagate data_mark on data dependencies of the statement 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.

Internally 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. Raise Invalid_argument when the stmt isn't a call.

Internally used to select a zone value at a program point.

Sourceval select_zone_at_entry_point_internal : Frama_c_kernel.Cil_types.kernel_function -> ?select:t -> Frama_c_kernel.Locations.Zone.t -> Mark.t -> t

Internally 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.

Sourceval select_zone_at_end_internal : Frama_c_kernel.Cil_types.kernel_function -> ?select:t -> Frama_c_kernel.Locations.Zone.t -> Mark.t -> t

Internally 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.

Sourceval select_modified_output_zone_internal : Frama_c_kernel.Cil_types.kernel_function -> ?select:t -> Frama_c_kernel.Locations.Zone.t -> Mark.t -> t

Internally 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...

Sourceval select_stmt_ctrl_internal : Frama_c_kernel.Cil_types.kernel_function -> ?select:t -> Frama_c_kernel.Cil_types.stmt -> t

Internally used to select a statement reachability : Only propagate a ctrl_mark on the statement control dependencies.

Sourceval select_entry_point_internal : Frama_c_kernel.Cil_types.kernel_function -> ?select:t -> Mark.t -> t
Sourceval select_return_internal : Frama_c_kernel.Cil_types.kernel_function -> ?select:t -> Mark.t -> t
Sourceval select_pdg_nodes_internal : Frama_c_kernel.Cil_types.kernel_function -> ?select:t -> Pdg_types.PdgTypes.Node.t list -> Mark.t -> t

Internally used to select PDG nodes :

  • if is_ctrl_mark m, propagate ctrl_mark on ctrl dependencies of the statement
  • if is_addr_mark m, propagate addr_mark on addr dependencies of the statement
  • if is_data_mark m, propagate data_mark on data dependencies of the statement Marks the node with a spare_mark and propagate so that the dependencies that were not selected yet will be marked spare.
