Now I use gem5 + dramsim2 simulator.
In this case, when I use in order or O3 option, simulator aborted and I can
see follow messages.
command line :
./build/X86_FS/gem5.opt configs/example/fs.py
--kernel=x86_64-vmlinux-2.6.22.9 --script=configs/script/hello.rcs --caches
--l2cache -d

======================
I wonder why this problem is occur. Can I use gem5 + dramsim2 in full
system mode with O3 option?
