* Automate fixing BSS ordering * Typo * Some cleanups * Move pragma check after printing BSS info * Some proofreading * multiprocessing, require version, some colors * Tweak output * Black + mypy * Move logging and sys.exit out of helper functions * Use stdout instead of stderr in fix_bss.py * Add suggestion to conflicting offsets error Co-authored-by: Dragorn421 <Dragorn421@users.noreply.github.com> * Remove var = list[T]() * Improve error handling Co-authored-by: Dragorn421 <Dragorn421@users.noreply.github.com> * Add error if no pointers to BSS * Add comment about process_file_worker * Only print updates if stdout is a tty * Use new binary-search-esque candidate generation algorithm Co-authored-by: Dragorn421 <Dragorn421@users.noreply.github.com> * Add Wikipedia link * More comment tweaks --------- Co-authored-by: Dragorn421 <Dragorn421@users.noreply.github.com>
