--  This package exists to initialize the TSD record of the main task and in
--  the process, allocate and initialize the secondary stack for the main task.
--  The initialization routine is contained within its own package because
--  System.Soft_Links and System.Secondary_Stack are both Preelaborate packages
--  that are the parents to other Preelaborate System packages.

--  Ideally, the secondary stack would be set up via __gnat_runtime_initialize
--  to have the secondary stack active as early as possible and to remove the
--  awkwardness of System.Soft_Links depending on a non-Preelaborate package.
--  However, as this procedure only exists from 2014, for bootstrapping
--  purposes the elaboration mechanism is used instead to perform these
--  functions.

package System.Soft_Links.Initialize is
   pragma Elaborate_Body;
   --  Allow this package to have a body
end System.Soft_Links.Initialize;
