fix up the recordEvent stuff to support ignoring events
arch/alpha/ev5.cc: cpu/simple_cpu/simple_cpu.cc: update for new event interface base/stats/events.cc: implement the ignore event function which matches sim objects from which to ignore events. Make insert event like insert data and make it able to insert many events in a single transaction with the database. base/stats/events.hh: Make it possible to ignore events sim/sim_object.cc: make recordEvent a member function of SimObject to implement the ignore function easily sim/sim_object.hh: implement the ignore event stuff in the sim object. This is a bit of a hack, but an easy place to put it. --HG-- extra : convert_revision : ba3f25a14ad03662c53fb35514860d69be8cd4f0
