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
