procedure Remove_Context (N : Node_Id);
-- Removes the entities from the context clause of the given compilation

-- end of the main unit the visibility table won't be needed in any case.
-- For a child unit, remove parents and their context as well.
procedure Remove_Private_With_Clauses (Comp_Unit : Node_Id);
-- The private_with_clauses of a compilation unit are visible in the
-- private part of a nested package, even if this package appears in
-- the visible part of the enclosing compilation unit. This Ada 2005
-- rule imposes extra steps in order to install/remove the private_with

-- Load and analyze the body of a context unit that is generic, or that
-- contains generic units or inlined units. The body becomes part of the
-- semantic dependency set of the unit that needs it. The returned result
-- in OK is True if the load is successful, and False if the requested file
-- cannot be found. If the flag Do_Analyze is false, the unit is loaded and
-- parsed only. This allows a selective analysis in some inlining cases
-- where a full analysis would lead so circularities in the back-end.
