NAME
llvm-readelf - 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.
If input is "-", llvm-readelf reads from standard input. Otherwise, it will read from the specified filenames.
OPTIONS
- --all, -a
- Equivalent to specifying all the main display options relevant to the file format.
- --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.
- --decompress, -z
- Dump decompressed section content when used with -x or -p. If the section(s) are not compressed, they are displayed as is.
- --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.
- --extra-sym-info
- Display extra information (section name) when showing symbols.
- --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.
- --memtag
- Display information about memory tagging present in the binary. This includes various memtag-specific dynamic entries, decoded global descriptor sections, and decoded Android-specific ELF notes.
- --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.
- --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>.
EXIT STATUS
llvm-readelf returns 0 under normal operation. It returns a non-zero exit code if there were any errors.
