💖 SANCOV(1) 💖

okay bestie, this is the manual page for sancov — that's the User Commands girlie, section 1. let's get into it 🫶

✨ NAME ✨

sancov — literally just the manual page for sancov 22. that's it, that's the name. 💅

🌸 DESCRIPTION 🌸

🔍 OVERVIEW: Sanitizer Coverage Processing Tool (sancov)

okay so. this tool is the Sanitizer Coverage Processing Tool (yes, that's sancov, iykyk) and the way that it eats is: it can extract various coverage-related information from any of these three snack types:

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

but here's the tea ☕ — depending on which action you pick, the tool expects different input files. no cap:

• -print-coverage-pcs — wants coverage-instrumented binary files
• -print-coverage — wants .sancov files
• -diff — wants two .sancov files and the --output option
• -union — wants one or more .sancov files and the --output option
• <other actions> — wants .sancov files and the corresponding binary files, plus .symcov files

🚀 USAGE

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

that's the whole vibe. action first, then feed her the files. 💫

💅 Action (required)

like, you have to pick one. this is not optional, bestie.

• -covered-functions — print all covered functions. all of them. every single one. 👑
• -diff — compute the difference between two sancov files (that's A - B, do the math ✨) and write it to the new output sancov file.
• -html-report — REMOVED. 💀 it's gone girl. use -symbolize & coverage-report-server.py instead.
• -merge — merges reports. union but make it fusion cuisine 🍓
• -not-covered-functions — print all not covered functions. the ones that ghosted the vibe check 🙈
• -print-coverage-pcs — print coverage instrumentation points addresses.
• -print-coverage-stats — print coverage statistics. numbers girlies rise 🌈
• -print — print coverage addresses.
• -symbolize — produces a symbolized JSON report from a binary report. glow-up in file format form ✨
• -union — compute the union of multiple sancov files and write it to the new output sancov file.

🎀 Generic Options

the basics, the essentials, the main character energy:

• -help — display this help. your knight in shining armor 🫶
• -h — alias for --help.
• -version — display the version. who am i? 👀
• -v — alias for --version.

---

⭐ OPTIONS ⭐

here come the flags, bestie. all of them. not a single one skipped, we don't do that here 💖

• -demangle=0 — alias for --no-demangle.
• -demangle — demangle function names. un-mangle them. make them legible. iconic behavior 🧚
• -ignorelist=<string> — ignorelist file, in sanitizer ignorelist format.
• -no-demangle — do not demangle function names.
• -no-skip-dead-files — list dead source files in reports.
• -output=<string> — output file for the diff and union actions. (remember, those two need this one!)
• -skip-dead-files=0 — alias for --no-skip-dead-files.
• -skip-dead-files — do not list dead source files in reports.
• -strip_path_prefix=<string> — strip this prefix from file paths in reports ✂️
• -use_default_ignorelist=0 — alias for --no-use_default_ignore_list.

lowkey important: that alias is spelled --no-use_default_ignore_list, with the underscore, not the dash. don't come for me, i'm just the messenger 💀
