LLVM-OTOOL(1)

💖 NAME 💖

Bestie, meet llvm-otool(1) — the LLVM Mach-O dumping tool, aka the little icon that stares into Mach-O files so you don’t have to. This is the LLVM manual page, and we’re gonna walk it together, no cap.

🎀 SYNOPSIS 🎀

llvm-otool [option…] [file…]

✨ DESCRIPTION ✨

llvm-otool is a tool for dumping Mach-O files, periodt.

It attempts to be command-line-compatible and output-compatible with macOS’s otool. Like, it’s giving “I match the command line and the output” energy, and honestly? Respect.

💅 OPTIONS 💅

• -arch <value> — selects the slice of a universal Mach-O file. Main-character slice selection, honestly.
• -C — prints linker optimization hints.
• -D — prints the shared library id.
• -d — prints the data section.
• -f — prints universal headers.
• -G — prints the data-in-code table.
• --help-hidden — prints help for hidden flags. Secret menu vibes 👀
• --help — prints help.
• -h — prints the mach header.
• -I — prints the indirect symbol table.
• -j — prints opcode bytes.
• -L — prints used shared libraries.
• -l — prints load commands.
• -mcpu=<value> — selects cpu for disassembly.
• -o — prints the Objective-C segment.
• -P — prints the __TEXT,__info_plist section as strings.
• -p <function name> — starts disassembly at <function name>.
• -r — prints relocation entries.
• -s <segname> <sectname> — prints contents of section.
• -t — prints the text section.
• --version — prints version.
• -V — symbolizes disassembled operands (implies -v).
• -v — verbose output / disassemble when printing text sections.
• -X — omits leading addresses or headers.
• -x — prints all text sections.
• @<FILE> — reads command-line options and commands from response file <FILE>. It’s giving “options in a little file,” iconic.

🦋 EXIT STATUS 🦋

llvm-otool exits with a non-zero exit code if there is an error. Otherwise, it exits with code 0. That’s the whole vibe check: error = non-zero, no error = 0.
