LLVM-ADDR2LINE(1)

okay so bestie, welcome to the LLVM-ADDR2LINE(1) manual page — it's the LLVM page for a tool that's literally a drop-in replacement for addr2line, and it's giving "I speak both languages" energy. ngl, it ate. 💅

💖 NAME 💖

llvm-addr2line — a drop-in replacement for addr2line. periodt.

✨ SYNOPSIS ✨

llvm-addr2line [options]

🌸 DESCRIPTION 🌸

okay so llvm-addr2line is an alias for the llvm-symbolizer(1) tool (<llvm-symbolizer.html>) with different defaults. The whole goal is highkey to make it a drop-in replacement for GNU's addr2line. no cap. 🫶

Here are some of those differences, and bestie, they are lowkey important:

• 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. 🔥
• llvm-addr2line defaults not to print function names. Use -f to enable that (llvm-symbolizer.html#llvm-symbolizer-opt-f).
• llvm-addr2line defaults not to demangle function names. Use -C to switch the demangling on (llvm-symbolizer.html#llvm-symbolizer-opt-c).
• llvm-addr2line defaults not to print inlined frames. Use -i to show inlined frames for a source code location in an inlined function (llvm-symbolizer.html#llvm-symbolizer-opt-i).
• llvm-addr2line uses --output-style=GNU by default (llvm-symbolizer.html#llvm-symbolizer-opt-output-style).
• llvm-addr2line parses options from the environment variable LLVM_ADDR2LINE_OPTS instead of from LLVM_SYMBOLIZER_OPTS. 🧚
• llvm-addr2line accepts an address with a + prefix, e.g. +0x00777fff. This is treated as a symbol name by llvm-symbolizer. 💀
