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 at-
tributes 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 rela-
tive 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 ma-
chine consumption.
--section-groups, -g
Display section groups.
--expand-relocs
When used with --relocations, display each relocation in an ex-
panded 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 de-
fault.
--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 dis-
playing 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>.
EXIT STATUS
llvm-readelf returns 0 under normal operation. It returns a non-zero
exit code if there were any errors.
