Host OS: Ubuntu 12.04 LTS Host CPU: Intel i7-2600 3.40 GHz I'm trying to debug an x86 application on an O3CPU using syscall emulation, but static_inst.cc panics or runs into an assertion error. Ideas for how I can debug or solve this issue?
Example command 1 (causing panic): build/X86/gem5.opt --debug-flags=Exec --debug-file=debug.txt configs/example/se.py --cpu-type=O3CPU --caches -c tests/test-progs/hello/bin/x86/linux/hello Terminal output: > $build/X86/gem5.opt --debug-flags=Exec --debug-file=debug.txt >> configs/example/se.py --cpu-type=O3CPU --caches -c >> tests/test-progs/hello/bin/x86/linux/hello > > gem5 Simulator System. http://gem5.org > > gem5 is copyrighted software; use the --copyright option for details. > > >> gem5 version 21.1.0.0 > > gem5 compiled Aug 10 2021 19:50:47 > > gem5 started Aug 10 2021 22:07:52 > > gem5 executing on uc12, pid 1240379 > > command line: build/X86/gem5.opt --debug-flags=Exec --debug-file=debug.txt >> configs/example/se.py --cpu-type=O3CPU --caches -c >> tests/test-progs/hello/bin/x86/linux/hello > > >> warn: membus.slave is deprecated. `slave` is now called `cpu_side_ports` > > warn: membus.slave is deprecated. `slave` is now called `cpu_side_ports` > > warn: membus.slave is deprecated. `slave` is now called `cpu_side_ports` > > warn: membus.slave is deprecated. `slave` is now called `cpu_side_ports` > > warn: membus.slave is deprecated. `slave` is now called `cpu_side_ports` > > warn: membus.master is deprecated. `master` is now called `mem_side_ports` > > warn: membus.master is deprecated. `master` is now called `mem_side_ports` > > warn: membus.slave is deprecated. `slave` is now called `cpu_side_ports` > > Global frequency set at 1000000000000 ticks per second > > warn: No dot file generated.
