tools/clang/unsafe_todo_remover/README.md
UNSAFE_TODO() is a macro that disables the -Wunsafe-buffer-usage compiler
warning. This tool identifies and removes the ones that become safe to remove.
This happens frequently, because code evolves and usage of std::array and base::span increases over time.
To get maximum coverage, this tools cross-compiles on every platforms except
iOS. Please update your .gclient with:
target_os = ["win", "android", "linux", "chromeos", "mac", "fuchsia"]
Moreover, you need at least 5TB of free disk space to store all the build artifacts.
# 1. Run analysis:
# Start the verification process. Progress is saved to `out.json` and can be
# resumed at any time
./unsafe_todo_remover.py
# 2. Apply fixes:
# Once the analysis finds safe-to-remove wrappers, apply the changes to the
# source code
./unsafe_todo_remover.py --apply
