Hi Nilay, The error only seems to manifest itself with the latest changeset applied. However, after a bit of digging, the actual problem seems to be related to the conditional flags in the CPU model (valgrind output below):
==11917== Conditional jump or move depends on uninitialised value(s) ==11917== at 0x96A37C: X86ISAInst::WripFlags::execute(TimingSimpleCPU*, Trace::InstRecord*) const (timing_simple_cpu_exec.cc:11421) ==11917== by 0xF1BDFA: TimingSimpleCPU::completeIfetch(Packet*) (timing.cc:685) ==11917== by 0xF1C95C: TimingSimpleCPU::fetch() (timing.cc:566) ==11917== by 0xF1D9F6: TimingSimpleCPU::advanceInst(RefCountingPtr<FaultBase>) (timing.cc:629) ==11917== by 0xF1BE9C: TimingSimpleCPU::completeIfetch(Packet*) (timing.cc:700) ==11917== by 0xF1C95C: TimingSimpleCPU::fetch() (timing.cc:566) ==11917== by 0xF1D9F6: TimingSimpleCPU::advanceInst(RefCountingPtr<FaultBase>) (timing.cc:629) ==11917== by 0xF1BE9C: TimingSimpleCPU::completeIfetch(Packet*) (timing.cc:700) ==11917== by 0xF1F07B: TimingSimpleCPU::IcachePort::recvTimingResp(Packet*) (timing.cc:726) ==11917== by 0xD0795C: PacketQueue::trySendTiming() (packet_queue.cc:147) ==11917== by 0xD07A4A: PacketQueue::sendDeferredPacket() (packet_queue.cc:183) ==11917== by 0xC4F8A3: EventQueue::serviceOne() (eventq.cc:204) Could you have a look at this (as I believe you were the last one to make changes to this bit of the code)?
