All these functions find the nodes needed for various kind of annotations.

Build graphs (PDG) for the function (see module Build.BuildPdg) to represent the dependencies between instructions in order to use it for slicing purposes.

Internal information about control dependencies

in_marks_to_caller translate the input information part returned by mark_and_propagate into (node, mark) list related to a call.

Program Dependences Graph.

Types data_state and Node.t come froms this module

Register external functions into Db.

PDG (program dependence graph) access functions.

This module can be useful to store some information about different elements of a function.

This module provides elements to mapped information (here called 'marks') to PDG elements and propagate it along the dependencies.

This module defines the types that are used to store the PDG of a function.
