They are not with'ed from the spec -- of System.Standard_Library, since this would cause order of elaboration -- problems (Elaborate_Body would have the same problem). pragma Polling (Off); -- We must turn polling off for this unit, because otherwise we get -- elaboration circularities with Ada.Exceptions if polling is on. pragma Warnings (Off); -- Kill warnings from unused withs. These unused with's are here to make -- sure the relevant units are loaded and properly elaborated. with System.Soft_Links; -- Referenced directly from generated code using external symbols so it -- must always be present in a build, even if no unit has a direct with -- of this unit. Also referenced from exception handling routines. -- This is needed for programs that don't use exceptions explicitly but -- direct calls to Ada.Exceptions are generated by gigi (for example, -- by calling __gnat_raise_constraint_error directly). with System.Memory; -- Referenced directly from generated code using external symbols, so it -- must always be present in a build, even if no unit has a direct with -- of this unit. pragma Warnings (On); package body System.Standard_Library is Runtime_Finalized : Boolean := False; -- Set to True when adafinal is called.
