🌸 DESCRIPTION 🌸

🦋 OVERVIEW

llvm object file dumper — okay so basically it's the tool that opens up object files and shows you everything inside, like a little x-ray for your binaries. iconic behavior honestly 🔥

🎀 USAGE

llvm-objdump [options] <input object files>

✨ OPTIONS ✨

• --adjust-vma=offset — bumps up every displayed address by the offset you give it 📏
• --all-headers — shows you literally every header there is, plus the relocation entries and the symbol table. the full tour, no skips 👑
• --arch-name=<value> — which target arch to disassemble for. run --version to see what targets you even have available 🎯
• --archive-headers — prints out the archive header info
• -a — alias for --archive-headers
• --build-id=<hex> — the Build ID you're hunting for. once it's found, it gets added as an input file 🔍
• -C — alias for --demangle
• --debug-file-directory=<dir> — the directory path where it should go looking for debug files
• --debug-vars-indent=<value> — how far to indent the source-level variable display, measured from the start of the disassembly
• --debug-vars=<value> — prints where source-level variables actually live (in registers or memory) right alongside the disassembly. supported formats: ascii, unicode (that one's the default) 💖
• --debuginfod — use debuginfod to go find debug files
• --demangle — unmangles those cursed symbol names so you can actually read them
• --disassemble-all — disassembles every section it finds in the input files, no mercy
• --disassemble-symbols=<value> — a list of symbols to disassemble. if --demangle is on, you can pass demangled names, otherwise it's mangled names only 🫶
• --disassemble-zeroes — do not skip over blocks of zeroes while disassembling
• --disassembler-options=options — pass along target-specific disassembler options
• --disassemble — disassembles all the executable sections found in the input files

• -d — alias for --disassemble
• --fault-map-section — prints the content of the fault map section

• --mcpu=cpu-name — target a specific cpu type (--mcpu=help for the details)
• -M <value> — alias for --disassembler-options=
• -m — alias for --macho
• --no-addresses — alias for --no-leading-addr
• --no-debuginfod — do not use debuginfod to find debug files
• --no-leading-addr — while disassembling, don't print the leading addresses for instructions or inline relocations
• --no-print-imm-hex — do not use hex format for immediate values
• --no-show-raw-insn — while disassembling instructions, don't print the instruction bytes.
• --offloading — shows the content of the offloading section
• --prefix-strip=prefix — strips out the initial directories from absolute paths. does nothing at all without --prefix
• --prefix=prefix — adds a prefix to absolute paths
• --print-imm-hex — use hex format for immediate values (this is the default ✨)
• --private-headers — shows format-specific file headers
• -p — alias for --private-headers
• --raw-clang-ast — dumps the raw binary contents of the clang AST section

• --source — while disassembling, shows the source interleaved with the disassembly. implies --disassemble
• --start-address=address — sets the start address for disassembling, printing relocations, and printing symbols
• --stop-address=address — sets the stop address for disassembling, printing relocations, and printing symbols

🌟 one more thing bestie: pass @FILE as an argument to read options from FILE. yes, that's literally it, it's so cute 🎀
