This is a set of scripts to use when triaging compiler problem by using the bisecting functionality included in the sysroot_wrapper.hardened. The only script that you need to create for your triaging problem is the test_script.sh (The ones in this directory are here only as an example). Before running the binary searcher tool you will need to run the setup script: ./sysroot_wrapper/setup.sh ${board} ${remote_ip} ${package} This setup script will ensure your $BISECT_DIR is properly populated and generate a common variable script for the convenience of the scripts in ./sysroot_wrapper To run the binary searcher tool with these scripts, execute it like this: ./binary_search_state.py --get_initial_items=./sysroot_wrapper/get_initial_items.sh --switch_to_good=./sysroot_wrapper/switch_to_good.sh --switch_to_bad=./sysroot_wrapper/switch_to_bad.sh --test_script=./sysroot_wrapper/test_script.sh --noincremental --file_args 2>&1 | tee /tmp/binary_search.log Finally once done you will want to run the cleanup script: ./sysroot_wrapper/cleanup.sh For more information on how to use the sysroot_wrapper to do object file triaging see: https://sites.google.com/a/google.com/chromeos-toolchain-team-home2/home/team-tools-and-scripts/bisecting-compiler-problems
