72// Revision 1.3  2011/08/26 20:45:39  acg
73//  Andy Goodrich: moved the modification log to the end of the file to
74//  eliminate source line number skew when check-ins are done.
75//
76// Revision 1.2  2011/02/18 20:23:45  acg
77//  Andy Goodrich: Copyright update.
78//
79// Revision 1.1.1.1  2006/12/15 20:20:04  acg
80// SystemC 2.3
81//
82// Revision 1.7  2006/02/02 23:42:37  acg
83//  Andy Goodrich: implemented a much better fix to the sc_event_finder
84//  proliferation problem. This new version allocates only a single event
85//  finder for each port for each type of event, e.g., pos(), neg(), and
86//  value_change(). The event finder persists as long as the port does,
87//  which is what the LRM dictates. Because only a single instance is
88//  allocated for each event type per port there is not a potential
89//  explosion of storage as was true in the 2.0.1/2.1 versions.
90//
91// Revision 1.6  2006/02/02 21:26:34  acg
92//  Andy Goodrich: pulled out the check I just stuck into the
93//  sc_event_finder::free_instances() method. It turns out the LRM says that
94//  sc_event_finder instances are valid as long as the sc_module hierarchy is
95//  valid, so we can't give the user a call to free the instances.
96//
97// Revision 1.5  2006/02/02 21:10:52  acg
98//  Andy Goodrich: added check for end of elaboration to the static method
99//  sc_event_finder::free_instances(). This will allow the method to be
100//  made public if that is desired.
101//
102// Revision 1.4  2006/02/02 20:43:09  acg
103//  Andy Goodrich: Added an existence linked list to sc_event_finder so that
104//  the dynamically allocated instances can be freed after port binding
105//  completes. This replaces the individual deletions in ~sc_bind_ef, as these
106//  caused an exception if an sc_event_finder instance was used more than
107//  once, due to a double freeing of the instance.
108//
109// Revision 1.3  2006/01/13 18:47:41  acg
110// Added $Log command so that CVS comments are reproduced in the source.
