Stats & serialization tweaks & cleanup. Unserializing from
a checkpoint now gives identical results to running from scratch and doing at switchover at the same cycle! - CPUs start at cycle 0 again, not cycle 1. - curTick is now serialized & unserialized. - Stats get reset in main (before event loop). Since this is done after curTick is unserialized, simTicks gets set correctly for running from a checkpoint. - Simplify serialization to happen in a single pass. - s/Serializeable/Serializable/ arch/alpha/isa_traits.hh: dev/etherlink.hh: sim/eventq.cc: sim/eventq.hh: s/Serializeable/Serializable/ kern/tru64/tru64_system.cc: sim/process.cc: Make initial CPU activation on cycle 0 again (not 1). sim/main.cc: Reset stats before getting started. Make error message on falling out of event loop more meaningful. sim/serialize.cc: sim/serialize.hh: Get rid of now-useless initial pass; serialization is done in a single pass now. Serialize & unserialize curTick. Wrap curTick and mainEventQueue in a "globals" Serializable object. s/Serializeable/Serializable/ sim/sim_object.cc: Add static function to serialize all SimObjects. sim/sim_object.hh: Add static function to serialize all SimObjects. s/Serializeable/Serializable/ --HG-- extra : convert_revision : 9dcc411d0009b54b8eb61c3a509680b81b9f6f68
