LLVM-ADDR2LINE(1)

💖 LLVM-ADDR2LINE 💖

okay bestie, welcome to llvm-addr2line, a page from the LLVM manual collection (section 1, the user commands girlies 💅). she's a whole vibe and also a drop-in replacement for addr2line, so let's get into it ✨

🌸 NAME 🌸

llvm-addr2line — a drop-in replacement for addr2line. literally that's her job. no cap 🫶

---

✨ SYNOPSIS ✨

llvm-addr2line [options]

that's it. that's the whole thing. she takes options and she slays 💖

---

🦋 DESCRIPTION 🦋

okay so here's the tea 🍓: llvm-addr2line is an alias for the llvm-symbolizer(1) tool, but with different defaults. the goal is to make it a drop-in replacement for GNU's addr2line. she's cosplaying, but she's good at it 👑

here are some of those differences, and yes you need to know 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, hex is the moment, always 🌈
• llvm-addr2line defaults not to print function names. use -f to enable that.
• llvm-addr2line defaults not to demangle function names. use -C to switch the demangling on.
• llvm-addr2line defaults not to print inlined frames. use -i to show inlined frames for a source code location in an inlined function.
• llvm-addr2line uses --output-style=GNU by default. periodt.
• llvm-addr2line parses options from the environment variable LLVM_ADDR2LINE_OPTS instead of from LLVM_SYMBOLIZER_OPTS. not me remembering the right env var for once 😭

fr fr, if you came here expecting llvm-symbolizer behaviour out of the box, she said no 💀 flip the flags, bestie.
