🎀 DESCRIPTION 🎀

🌈 OVERVIEW: Sanitizer Coverage Processing Tool (sancov) 🌈

okay so real talk: this tool pulls all kinds of coverage-related info out of your stuff. the way it does this is by reading from coverage-instrumented binary files, from raw .sancov files, and from their symbolized .symcov version. 🫶

and here's the tea — depending on which action you pick, it wants different input files. so like, don't just throw everything at it and hope:

• -print-coverage-pcs — wants coverage-instrumented binary files 👑
• -print-coverage — wants .sancov files 🍓
• <other actions> — wants .sancov files and the corresponding binary files, or .symcov files 🦋

💅 USAGE 💅

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

⭐ Action (required) ⭐

you literally have to pick one, there's no "eh maybe later" option. 😭

• -covered-functions — prints all covered functions. every single one that got hit. 💚
• -html-report — REMOVED. like, gone gone. use -symbolize & coverage-report-server.py instead, bestie. 💀
• -merge — merges reports. mash them together, one report to rule them all. 🔥
• -not-covered-functions — prints all not covered functions. the ones that got left on read. 🙈
• -print-coverage-pcs — prints coverage instrumentation points addresses.
• -print-coverage-stats — prints coverage statistics. the numbers, the vibes, the whole picture. ✨
