objName as a member, instead it has the pure virtual function name(). SimObject
now has a objName member, and all classes derived directly from Serializeable
have to implement a name() function (which now makes them unique by pointer value)
cpu/simple_cpu/simple_cpu.cc:
Change initialization of Event to get rid of Serializeable naming
dev/etherlink.cc:
dev/etherlink.hh:
Seralizeable derived naming changes
sim/eventq.cc:
Serializeable derived naming changes, also changed serialization process so it
doesn't need to use nameChildren
sim/eventq.hh:
Serializeable derived naming changes, remove constructor for specifying event name
sim/serialize.cc:
Serializeable derived naming changes, remove setName function and the child naming
pass for serialization
sim/serialize.hh:
Serializeable derived naming changes, removed nameChildren, setName
sim/sim_object.cc:
sim/sim_object.hh:
Serializeable derived naming changes
