--  This package implements a compiler phase that determines the set

--  of live entities. For now entities are considered live when they

--  have at least one execution time reference.

package Live is

   procedure Collect_Garbage_Entities;

   --  Eliminate unreachable entities using a mark-and-sweep from

   --  the set of root entities, i.e. those having Is_Public set.

end Live;
