startup()

void gem5::ArmISA::ISA::startup ( )

overridevirtual

startup() is the final initialization call before simulation.

All state is initialized (including unserialized state, if any, such as the curTick() value), so this is the appropriate place to schedule initial event(s) for objects that need them.

Reimplemented from gem5::SimObject.

unserialize()

void gem5::ArmISA::ISA::unserialize ( CheckpointIn & cp )

Unserialize an object.
