In the past it happened several times that some changes in gem5 broke the SystemC coupling. Recently Accelera has changed the licence for SystemC from their own licence to Apache2.0, which is compatible with gem5. However, SystemC usually relies on the Boost library, but I was able to exchange the boost calls by c++11 alternatives. The recent SystemC version is placed into /ext and is integrated into gem5's build system. The goal is to integrate some SystemC tests for the CI in some following patches.

// 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!
