Hi, when i use python run_all.py -l ~/mediatek_kernel/llvm_bitcode_out -a 1 -m ~/mediatek_kernel/kernel-3.18/makeout.txt -g aarch64-linux-android-gcc -n 2 -o ~/mediatek_kernel/kernel-3.18/out -k ~/mediatek_kernel/kernel-3.18 -f ~/mediatek_kernel/ioctl_finder_out command line follow RADME.I allways get a lot of error log :
