🌸 NAME 🌸

sancov — the manual page for sancov 17, and honestly? it's giving coverage-tool royalty 👑

✨ DESCRIPTION ✨

OVERVIEW: Sanitizer Coverage Processing Tool (sancov) 🎀

okay so bestie, listen up 💖 this tool pulls all kinds of coverage-related info out of three different flavours of thing:

• coverage-instrumented binary files
• raw .sancov files
• their symbolized .symcov version

and the vibe check here is that depending on which action you pick, the tool expects totally different input files. no cap. here's the receipts:

• -print-coverage-pcs — wants coverage-instrumented binary files 🧚
• -print-coverage — wants .sancov files 🦋
• <other actions> — wants .sancov files & their corresponding binary files, plus .symcov files 💅

---

USAGE 📝

sancov [options] <action> <binary files...> <.sancov files...> <.symcov files...>

like, that's the whole shape of it. action in the middle, files trailing after like a lil entourage ✨

Generic Options 🫶

• --help — shows you all the available options. and if you're extra, --help-hidden shows you more 👀
