Hello,
While trying to run perlbench from SPEC2017 with se.py config on top of
Ubuntu 18 and perlbench compiled in Ubuntu 18 as well, it's seems that
compilation generated modern instruction that are not supported by Gem5.
log:
command line: ./build/X86/gem5.opt configs/example/se.py -c
/home/dan/SPEC2017/benchspec/CPU/500.perlbench_r/exe/perlbench_r_base.mytest-m64
-o /home/dan/SPEC2017/benchspec/CPU/500.perlbench_r/data/test/input/

dispSize = 0}

--> does anyone encounter with this problem? does anyone run SPEC2017 in
GEM5?
should I downgrade my ubuntu to previous version or there is any other
solution?
Thanks,
Dan Recher
