| -- the invocation graph, which reflects all activations of tasks, calls, and |

| -- instantiations within units. |

| -- Augment the library graph of Inv_Graph with information from |

| -- invocation graph Inv_Graph as follows: |

| -- |

| -- 1) Traverse the invocation graph starting from each elaboration |

| -- procedure of unit Root. |

| -- |

| -- 2) Each time the traversal transitions from one unit into another |

| -- unit Curr, add an invocation edge between predecessor Curr and |

| -- successor Root in the library graph. |

| -- 3) Do the above steps for all units with an elaboration procedure. |
