llvm-readelf - GNU-style LLVM Object Reader =========================================== .. program:: llvm-readelf SYNOPSIS -------- :program:`llvm-readelf` [*options*] [*input...*] DESCRIPTION ----------- The :program:`llvm-readelf` tool displays low-level format-specific information about one or more object files. If ``input`` is "``-``", :program:`llvm-readelf` reads from standard input. Otherwise, it will read from the specified ``filenames``. OPTIONS ------- .. option:: --all, -a Equivalent to specifying all the main display options relevant to the file format. .. option:: --addrsig Display the address-significance table. .. option:: --arch-specific, -A Display architecture-specific information, e.g. the ARM attributes section on ARM. .. option:: --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. .. option:: --demangle, -C Display demangled symbol names in the output. .. option:: --dependent-libraries Display the dependent libraries section. .. option:: --dyn-relocations Display the dynamic relocation entries. .. option:: --dyn-symbols, --dyn-syms Display the dynamic symbol table. .. option:: --dynamic-table, --dynamic, -d Display the dynamic table. .. option:: --cg-profile Display the callgraph profile section. .. option:: --histogram, -I Display a bucket list histogram for dynamic symbol hash tables. .. option:: --elf-linker-options Display the linker options section. .. option:: --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 :program:`readelf` output. ``JSON`` is JSON formatted output intended for machine consumption. .. option:: --section-groups, -g Display section groups. .. option:: --expand-relocs When used with :option:`--relocations`, display each relocation in an expanded multi-line format. .. option:: --file-header, -h Display file headers. .. option:: --gnu-hash-table Display the GNU hash table for dynamic symbols. .. option:: --hash-symbols Display the expanded hash table with dynamic symbol data. .. option:: --hash-table Display the hash table for dynamic symbols. .. option:: --headers, -e Equivalent to setting: :option:`--file-header`, :option:`--program-headers`, and :option:`--sections`. .. option:: --help Display a summary of command line options. .. option:: --hex-dump=<section[,section,...]>, -x Display the specified section(s) as hexadecimal bytes. ``section`` may be a section index or section name. .. option:: --needed-libs Display the needed libraries. .. option:: --no-demangle Do not display demangled symbol names in the output. On by default. .. option:: --notes, -n Display all notes. .. option:: --pretty-print When used with :option:`--elf-output-style`, JSON output will be formatted in a more readable format. .. option:: --program-headers, --segments, -l Display the program headers. .. option:: --raw-relr Do not decode relocations in RELR relocation sections when displaying them. .. option:: --relocations, --relocs, -r Display the relocation entries in the file. .. option:: --sections, --section-headers, -S Display all sections. .. option:: --section-data When used with :option:`--sections`, display section data for each section shown. This option has no effect for GNU style output. .. option:: --section-details, -t Display all section details. Used as an alternative to :option:`--sections`. .. option:: --section-mapping Display the section to segment mapping. .. option:: --section-relocations When used with :option:`--sections`, display relocations for each section shown. This option has no effect for GNU style output. .. option:: --section-symbols When used with :option:`--sections`, display symbols for each section shown. This option has no effect for GNU style output. .. option:: --stackmap Display contents of the stackmap section. .. option:: --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. .. option:: --string-dump=<section[,section,...]>, -p Display the specified section(s) as a list of strings. ``section`` may be a section index or section name. .. option:: --symbols, --syms, -s Display the symbol table. Also display the dynamic symbol table when using GNU output style for ELF. .. option:: --unwind, -u Display unwind information. .. option:: --version Display the version of the :program:`llvm-readelf` executable. .. option:: --version-info, -V Display version sections. .. option:: --wide, -W Ignored for GNU readelf compatibility. The output is already similar to when using -W with GNU readelf. .. option:: @<FILE> Read command-line options from response file `<FILE>`. EXIT STATUS ----------- :program:`llvm-readelf` returns 0 under normal operation. It returns a non-zero exit code if there were any errors. SEE ALSO -------- :manpage:`llvm-nm(1)`, :manpage:`llvm-objdump(1)`, :manpage:`llvm-readobj(1)`
