💅 llvm-readelf — the GNU-style LLVM Object Reader, bestie edition

okay so welcome to the llvm-readelf page from the LLVM manual set (yes that LLVM, the compiler queen 👑). She's here to spill the tea on what's actually inside your object files. lowkey iconic.

✨ NAME ✨

llvm-readelf — the GNU-style LLVM Object Reader 🦋

🌸 SYNOPSIS 🌸

llvm-readelf [options] [input…]

💖 DESCRIPTION 💖

The llvm-readelf tool displays low-level, format-specific information about one or more object files. like, it's giving x-ray vision for binaries fr fr 🔥

If input is -, llvm-readelf reads from standard input. Otherwise, it will read from the specified filenames.

🎀 OPTIONS 🎀

  • --all, -a — same energy as specifying all the main display options relevant to the file format. it's the "give me everything" button 💅
  • --addrsig — Display the address-significance table.
  • --arch-specific, -A — Display architecture-specific information, e.g. the ARM attributes section on ARM.
  • --bb-addr-map — Display the contents of the basic block address map section(s), which contain the address of each function, along with the relative offset of each basic block.
  • --demangle, -C — Display demangled symbol names in the output.
  • --dependent-libraries — Display the dependent libraries section.
  • --dyn-relocations — Display the dynamic relocation entries.
  • --dyn-symbols, --dyn-syms — Display the dynamic symbol table.
  • --dynamic-table, --dynamic, -d — Display the dynamic table.
  • --cg-profile — Display the callgraph profile section.
  • --histogram, -I — Display a bucket list histogram for dynamic symbol hash tables.
  • --elf-linker-options — Display the linker options section.
  • --elf-output-style=<value> — Format ELF information in the specified style. Valid options are LLVM, GNU, and JSON. LLVM output is an expanded and structured format. GNU (the default) output mimics the equivalent GNU readelf output. JSON is JSON formatted output intended for machine consumption.
  • --section-groups, -g — Display section groups.
  • --expand-relocs — When used with --relocations, display each relocation in an expanded multi-line format.
  • --file-header, -h — Display file headers.
  • --gnu-hash-table — Display the GNU hash table for dynamic symbols.
  • --hash-symbols — Display the expanded hash table with dynamic symbol data.
  • --hash-table — Display the hash table for dynamic symbols.
  • --headers, -e — Equivalent to setting: --file-header, --program-headers, and --sections.
  • --help — Display a summary of command line options.
  • --hex-dump=<section[,section,...]>, -x — Display the specified section(s) as hexadecimal bytes. section may be a section index or section name.
  • --needed-libs — Display the needed libraries.
  • --no-demangle — Do not display demangled symbol names in the output. On by default.
  • --notes, -n — Display all notes.
  • --pretty-print — When used with --elf-output-style, JSON output will be formatted in a more readable format.
  • --program-headers, --segments, -l — Display the program headers.
  • --raw-relr — Do not decode relocations in RELR relocation sections when displaying them.
  • --relocations, --relocs, -r — Display the relocation entries in the file.
  • --sections, --section-headers, -S — Display all sections.
  • --section-data — When used with --sections, display section data for each section shown. This option has no effect for GNU style output.
  • --section-details, -t — Display all section details. Used as an alternative to --sections.
  • --section-mapping — Display the section to segment mapping.
  • --section-relocations — When used with --sections, display relocations for each section shown. This option has no effect for GNU style output.
  • --section-symbols — When used with --sections, display symbols for each section shown. This option has no effect for GNU style output.
  • --stackmap — Display contents of the stackmap section.
  • --stack-sizes — Display the contents of the stack sizes section(s), i.e. pairs of function names and the size of their stack frames. Currently only implemented for GNU style output.
  • --string-dump=<section[,section,...]>, -p — Display the specified section(s) as a list of strings. section may be a section index or section name.
  • --symbols, --syms, -s — Display the symbol table. Also display the dynamic symbol table when using GNU output style for ELF.
  • --unwind, -u — Display unwind information.
  • --version — Display the version of the llvm-readelf executable.
  • --version-info, -V — Display version sections.
  • --wide, -W — Ignored for GNU readelf compatibility. The output is already similar to when using -W with GNU readelf.
  • @<FILE> — Read command-line options from response file <FILE>.
bestie there are literally so many options here, and you gotta keep them all in mind — none of them are skippable 💀

🫶 EXIT STATUS 🫶

llvm-readelf returns 0 under normal operation. It returns a non-zero exit code if there were any errors. so if it's mad at you, you'll know 💖
