It is probably that the binary include some recent instruction while gem5 does
not simulate it yet. Especially if it run well in real hardware (which
workload? Run well in which real hardware?).
The best case is that you can set different compiler options to avoid
generation of those gem5-non-support instructions. -march=athlon64 is really
not a good idea. It is too old.

主 题：[gem5-dev] Unrecognized/invalid instruction executed error when using x86
ISA
I am running SPEC2017 benchmarks and I was flagged with this error
src/arch/x86/faults.cc:132: panic: Unrecognized/invalid instruction executed:
{
leg = 0x10,
rex = 0x2,
vex/xop = 0x5,
op = {
type = three byte 0f38,
op = 0x19,
},
modRM = 0,
sib = 0,
immediate = 0,
displacement = 0
dispSize = 0}
Memory Usage: 8789364 KBytes
Program aborted at tick 648666304
Adding the flag -march=athlon64 while compiling the benchmark as suggested here

<https://www.mail-archive.com/gem5-dev@gem5.org/msg28965.html > also didn't
help. Does anyone have a solution to this?
Thanks
