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