Change tickCycles numCycles stat name to totalTickCycles os as not to clash with the name of the tickCycles stat of the same class. Declared the params passed to the TickedObject constructer as const. Call ClockedObject::regStats() from the TickedObject::regStats to ensure the correct initialization of the base class (ClockedObject) stats Change-Id: I6cf5bbe10fa27f2ad0e31d9f70ec3be47fe41455 Signed-off-by: Andreas Sandberg <andreas.sandberg@arm.com> Reviewed-on: https://gem5-review.googlesource.com/3964 Reviewed-by: Jason Lowe-Power <jason@lowepower.com> Maintainer: Jason Lowe-Power <jason@lowepower.com>
