💖 LLVM-CXXFILT(1) 💖

okay bestie, welcome to the llvm-cxxfilt page, from the LLVM fam ✨ this is the manual for a symbol name demangler, and yes that word is real and yes it's as iconic as it sounds 🎀

✨ NAME ✨

llvm-cxxfilt — LLVM symbol name demangler 💅

---

🌸 SYNOPSIS 🌸

llvm-cxxfilt [options] [mangled names...]

---

🦋 DESCRIPTION 🦋

so basically llvm-cxxfilt is a symbol demangler, and the whole vibe is that you can use it as a replacement for the GNU c++filt tool. it takes a bunch of symbol names and prints their demangled form on the standard output stream. and if a name can't be demangled? no drama, it just gets printed exactly as-is, no notes 🫶

if you don't give it any names on the command-line, it reads names interactively from the standard input stream. and when it's reading from standard input, each input line gets split on characters that aren't part of valid Itanium name manglings — meaning characters that aren't alphanumeric, '.', '$', or '_' 💫 the separators between names get copied to the output as-is, so nothing gets lost, periodt.

---

🔥 EXAMPLE 🔥

$ llvm-cxxfilt _Z3foov _Z3bari not_mangled
foo()
bar(int)
not_mangled
$ cat input.txt
| _Z3foov *** _Z3bari *** not_mangled |
$ llvm-cxxfilt < input.txt
| foo() *** bar(int) *** not_mangled |

like… the way it just works 😭💖

👑 OPTIONS 👑

• --format=<value>, -s — which mangling scheme to assume. valid values are auto (the default, it auto-detects the style) and gnu (assume GNU/Itanium style). pick your fighter 💅
• --help, -h — print a summary of command line options 📝
• --help-list — print an uncategorized summary of command line options. yes, a different summary. it's giving variety ✨
• --no-strip-underscore, -n — do not strip a leading underscore. this is the default for all platforms except Mach-O based hosts 🌈
• --strip-underscore, -_ — strip a single leading underscore, if present, from each input name before demangling. this one's on by default on Mach-O based platforms 🍓
• --types, -t — attempt to demangle names as type names as well as function names. go both ways bestie 💜
• --version — display the version of the llvm-cxxfilt executable ⭐
• @<FILE> — read command-line options from response file <FILE> 📂

---

💀 EXIT STATUS 💀

llvm-cxxfilt returns 0 unless it hits a usage error, in which case a non-zero exit code gets returned. so if the number isn't zero, something went wrong, no cap 🙈
