32 -- This package exists to initialize the TSD record of the main task and in
33 -- the process, allocate and initialize the secondary stack for the main task.
34 -- The initialization routine is contained within its own package because
35 -- System.Soft_Links and System.Secondary_Stack are both Preelaborate packages
36 -- that are the parents to other Preelaborate System packages.
38 -- Ideally, the secondary stack would be set up via __gnat_runtime_initialize
39 -- to have the secondary stack active as early as possible and to remove the
40 -- awkwardness of System.Soft_Links depending on a non-Preelaborate package.
41 -- However, as this procedure only exists from 2014, for bootstrapping
42 -- purposes the elaboration mechanism is used instead to perform these
