-- This version of this package is for implementations which use
-- the stack limit approach (the limit of the stack is stored into a per
-- thread variable).
pragma Restrictions (No_Elaboration_Code);
-- We want to guarantee the absence of elaboration code because the binder
-- does not handle references to this package.
pragma Polling (Off);
-- Turn off polling, we do not want polling to take place during stack
-- checking operations. It causes infinite loops and other problems.
package System.Stack_Checking.Operations is
pragma Preelaborate;
procedure Initialize_Stack_Limit;
pragma Export (C, Initialize_Stack_Limit,
"__gnat_initialize_stack_limit");
-- This procedure is called before elaboration to setup the stack limit
-- for the environment task and to register the hook to be called at
-- task creation.
