| // 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 1.1.1.1 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. |
