Hi,
I've been using M5's ARM frontend with the AtomicSimpleCPU model for
a
while and it mostly works for simple binaries. Trying out the O3CPU
model, however, gives me :
FullO3CPU: Ticking main, FullO3CPU.
1322500: system.cpu: Thread 0: Deleting instructions from instruction
list.
1322500: system.cpu: ROB is not empty, squashing insts not in ROB.
m5.debug: build/ARM_SE/cpu/o3/bpred_unit_impl.hh:350: void
BPredUnit<Impl>::squash(const InstSeqNum&, const ArmISA::PCState&,
bool, ThreadID) [with Impl = O3CPUImpl, InstSeqNum = long unsigned
int, ThreadID = short int]: Assertion `pred_hist.front().seqNum ==
squashed_sn' failed.
Program aborted at cycle 1322500
Aborted
Is this a known issue? I have no knowledge of M5 internals so I can't
really make an educated guess as to what the problem could be. Has
someone else stumbled across this too?
Thanks.
