💅 LLVM-OTOOL(1) — the LLVM manual, bestie edition ✨

okay so this is llvm-otool, and it lives under the LLVM umbrella. she's a Mach-O dumping tool and honestly? she ate. 🍓

✨ NAME ✨

llvm-otool — Mach-O dumping tool 🫶

🎀 SYNOPSIS 🎀

llvm-otool [option...] [file...]

🦋 DESCRIPTION 🦋

llvm-otool is a tool for dumping Mach-O files. that's the whole vibe. 💅

she attempts to be command-line-compatible and output-compatible with macOS's otool — like, she's trying so hard to be that girl and ngl she's doing great at it. no cap.

🌸 OPTIONS 🌸

like a full menu of little flags, and every single one is iconic in her own way:

  • -a — print the archive header. 📦
  • -arch <value> — pick which slice of a universal Mach-O file you want. choose your fighter bestie.
  • -chained_fixups — print chained fixup information.
  • -C — print linker optimization hints. little helpful notes from the linker, cute.
  • -dyld_info — print bind and rebase information.
  • -D — print the shared library id.
  • -d — print the data section.
  • -f — print universal headers.
  • -G — print the data-in-code table.
  • --help-hidden — print help for the hidden flags. secret menu energy 🔥
  • --help — print help. the basics, love her.
  • -h — print the mach header.
  • -I — print the indirect symbol table.
  • -j — print opcode bytes.
  • -L — print the used shared libraries.
  • -l — print load commands.
  • -m — don't use archive(member) syntax. just say no to brackets ✋
  • -mcpu=<value> — select the cpu for disassembly.
  • -o — print the Objective-C segment.
  • -P — print the __TEXT,__info_plist section as strings.
  • -p <function name> — start disassembly at <function name>. jump right in, main character energy 👑
  • -r — print relocation entries.
  • -s <segname> <sectname> — print the contents of a section. two args, one job 💖
  • -t — print the text section.
  • --version — print version.
  • -V — symbolize disassembled operands (implies -v). note that she implies -v, so verbose comes along for the ride whether you asked or not 🙈
  • -v — verbose output / disassemble when printing text sections.
  • -X — omit leading addresses or headers. minimalist era.
  • -x — print all text sections. go big or go home.
  • @<FILE> — read command-line options and commands from response file <FILE>. iykyk 🌈

⭐ EXIT STATUS ⭐

llvm-otool exits with a non-zero exit code if there is an error. otherwise, she exits with code 0. so like... 0 means we're slaying, non-zero means something went sideways. periodt. 💀
