LLVM-ADDR2LINE(1)

🎀 llvm-addr2line(1) — LLVM manual page, bestie 🎀

✨ NAME ✨

okay so llvm-addr2line is literally a drop-in replacement for addr2line. that’s the whole vibe. 💅

🫶 SYNOPSIS 🫶

llvm-addr2line [options]

💅 DESCRIPTION 💅

llvm-addr2line is an alias for the llvm-symbolizer(1) tool, but with different defaults. the goal? make it a drop-in replacement for GNU’s addr2line. no cap.

here are some of those differences, bestie:

• hexadecimal addresses — llvm-addr2line interprets all addresses as hexadecimal and ignores an optional 0x prefix. meanwhile llvm-symbolizer attempts to determine the base from the literal’s prefix and defaults to decimal if there is no prefix. it’s giving “read the room, then read the prefix.”
• -f — function names are not printed by default. use -f to enable that. 🫶
• -C — function names are not demangled by default. use -C to switch the demangling on. slay.
• -i — inlined frames are not printed by default. use -i to show inlined frames for a source code location in an inlined function. iconic.
• –output-style=GNU — this is the default output style. yup, that exact spelling. 🙈
• LLVM_ADDR2LINE_OPTS — llvm-addr2line parses options from the environment variable LLVM_ADDR2LINE_OPTS instead of from LLVM_SYMBOLIZER_OPTS. main character env var energy. 👑
