1# Sysroot wrapper 2 3This is a set of scripts to use when triaging compiler problem by using 4the bisecting functionality included in the `sysroot_wrapper.hardened`. 5The only script that you need to create for your triaging problem is the 6`test_script.sh` (The ones in this directory are here only as an example). 7 8Before running the binary searcher tool you will need to run the setup script: 9 10``` 11./sysroot_wrapper/setup.sh ${board} ${remote_ip} ${package} 12``` 13 14This setup script will ensure your `$BISECT_DIR` is properly populated and 15generate a common variable script for the convenience of the scripts in 16`./sysroot_wrapper` 17 18To run the binary searcher tool with these scripts, execute it like this: 19 20``` 21./binary_search_state.py \ 22 --get_initial_items=./sysroot_wrapper/get_initial_items.sh \ 23 --switch_to_good=./sysroot_wrapper/switch_to_good.sh \ 24 --switch_to_bad=./sysroot_wrapper/switch_to_bad.sh \ 25 --test_script=./sysroot_wrapper/test_script.sh \ 26 --noincremental \ 27 --file_args \ 28 2>&1 | tee /tmp/binary_search.log 29``` 30 31Finally once done you will want to run the cleanup script: 32`./sysroot_wrapper/cleanup.sh` 33 34For more information on how to use the `sysroot_wrapper` to do object file 35triaging see: https://sites.google.com/a/google.com/chromeos-toolchain-team-home2/home/team-tools-and-scripts/bisecting-compiler-problems 36
