Sysroot wrapper
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
