LLVM-ADDR2LINE(1)

🌸 llvm-addr2line 💅 (LLVM manual page, bestie)

okay so you opened the man page for llvm-addr2line and honestly? icon behavior. this is the LLVM flavor of that whole tool family, and she's got range. let's get into it ✨

---

🎀 NAME 🎀

llvm-addr2line — a drop-in replacement for addr2line. that's it, that's the whole vibe. no cap. 💖

---

🦋 SYNOPSIS 🦋

llvm-addr2line [options]

literally just the command and some options. she's low maintenance like that 🫶

---

✨ DESCRIPTION ✨

okay so here's the tea: llvm-addr2line is an alias for the llvm-symbolizer(1) tool (peep llvm-symbolizer.html) — same tool, but with different defaults. the whole goal is to make it a drop-in replacement for GNU's addr2line. main character energy fr fr 👑

here are some of those differences, and yes bestie we're going through all of them:

• llvm-addr2line interprets all addresses as hexadecimal and ignores an optional 0x prefix, whereas llvm-symbolizer attempts to determine the base from the literal's prefix and defaults to decimal if there is no prefix. so like… she just knows it's hex. confident queen 💅
• llvm-addr2line defaults not to print function names. use -f (link: llvm-symbolizer.html#llvm-symbolizer-opt-f) to enable that. it's giving "ask before you show me the function names" 🙈
• llvm-addr2line defaults not to demangle function names. use -C (link: llvm-symbolizer.html#llvm-symbolizer-opt-c) to switch the demangling on. mangled names stay mangled until you say otherwise, iykyk 🔥
• llvm-addr2line defaults not to print inlined frames. use -i (link: llvm-symbolizer.html#llvm-symbolizer-opt-i) to show inlined frames for a source code location in an inlined function. the inlined frames are literally right there but she's not gonna overshare 🌸
• llvm-addr2line uses --output-style=GNU (link: llvm-symbolizer.html#llvm-symbolizer-opt-output-style) by default. GNU output style is her default outfit and she ate 💀
• llvm-addr2line parses options from the environment variable LLVM_ADDR2LINE_OPTS instead of from LLVM_SYMBOLIZER_OPTS. not me checking the right env var 😭 this is a whole different group chat

and that's the page, bestie. no gatekeeping, no missing flags. slay 💅✨

okay bye, and remember: the manual name is LLVM-ADDR2LINE(1) from the LLVM source, dated 2026-09-09, and the page footer says 15 — that's the version-and-date moment, so like… mark your calendar, periodt 🎀💖
