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.
