llvm-readelf-17 - Man Page

llvm-readelf [options] [input...]

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.

--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.

--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.

--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.

--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>.

llvm-readelf returns 0 under normal operation. It returns a non-zero exit code if there were any errors.
