LLVM-ADDR2LINE(1)

📦 version 23.1.3, in centos-stream 9

✨ NAME ✨

okay so bestie, welcome to the LLVM manual page for llvm-addr2line — aka LLVM-ADDR2LINE(1) if we're being formal 💅. it's literally a drop-in replacement for addr2line. that's the whole name, no notes.

🦋 SYNOPSIS 🦋

llvm-addr2line [options]

that's it. just [options], living its best life. slay. ✨

💅 DESCRIPTION 💅

okay so llvm-addr2line is an alias for the llvm-symbolizer(1) tool with different defaults. the goal? make it a drop-in replacement for GNU's addr2line. periodt. 💖

here are some of those differences, bestie:

  • address tea ☕: 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. it's giving different philosophies, honestly.
  • function names? by default it does not print them. use -f to enable that and let the function names have their main character moment. ✨
  • demangling? defaults not to demangle function names. use -C to switch the demangling on. lowkey a glow-up. 🎀
  • inlined frames? defaults not to print them. use -i to show inlined frames for a source code location in an inlined function. the inlined girlies need this. 💅
  • output style? it uses --output-style=GNU by default. iconic, no cap.
  • env var check 🦋: it parses options from the environment variable LLVM_ADDR2LINE_OPTS instead of from LLVM_SYMBOLIZER_OPTS. so yeah, check the right one, iykyk.
  • plus sign behavior 💀: it accepts an address with a + prefix, e.g. +0x00777fff. plot twist — this is treated as a symbol name by llvm-symbolizer. not me finding that out, fr fr.
