DESCRIPTION
eu-readelf displays information about one or more ELF format object
files. The options control what particular information to display.
elffile... are the object files to be examined. 32-bit and 64-bit ELF
files are supported, as are archives containing ELF files.
This program performs a similar function to objdump but it goes into
more detail and it exists independently of the BFD library, so if there
is a bug in BFD then readelf will not be affected.
OPTIONS
The long and short forms of options, shown here as alternatives, are
equivalent. At least one option in addition to -v or -H must be given.
ELF Input Selection
--dwarf-skeleton <file>
Used with -w to find the skeleton Compile Units in FILE associated
with the Split Compile units in a .dwo input file.
--elf-section [section]
Use the named SECTION (default .gnu_debugdata) as (compressed) ELF
input data
ELF Output Selection
-a
--all
Equivalent to specifying --file-header, --program-headers,
--sections, --symbols, --relocs, --dynamic, --notes,
--version-info, --arch-specific, --section-groups and --histogram.
-h
--file-header
Displays the information contained in the ELF header at the start
of the file.
-l
--program-headers
--segments
Displays the information contained in the file's segment headers,
if it has any.
-S
--sections
--section-headers
Displays the information contained in the file's section headers,
if it has any.
-g
--section-groups
Displays the information contained in the file's section groups, if
it has any.
-I
--histogram
Display a histogram of bucket list lengths when displaying the
contents of the symbol tables.
-s
--syms
--symbols [section name]
Displays the entries in symbol table section of the file, if it has
one. If a symbol has version information associated with it then
this is displayed as well. The version string is displayed as a
suffix to the symbol name, preceded by an @ character. For example
foo@VER_1. If the version is the default version to be used when
resolving unversioned references to the symbol then it is displayed
as a suffix preceded by two @ characters. For example foo@@VER_2.
--dyn-syms
Display (only) the dynamic symbol table.
-e
--exception
Display sections for exception handling.
-n
--notes [section name]
Displays the contents of the NOTE segments and/or sections, if any.
-r
--relocs
Displays the contents of the file's relocation section, if it has
one.
-d
--dynamic
Displays the contents of the file's dynamic section, if it has one.
-V
--version-info
Displays the contents of the version sections in the file, it they
exist.
-A
--arch-specific
Displays architecture-specific information in the file, if there is
any.
Additional output selection
-x <name>
--hex-dump=<name>
Displays the contents of the indicated section name as a
hexadecimal bytes.
-w
--debug-dump[=decodedline,=info,=info+,=abbrev,=pubnames,=aranges,=macro,=frames,=str,=loc,=ranges,=gdb_index,=addr]
Displays the contents of the DWARF debug sections in the file, if
any are present. Compressed debug sections are automatically
decompressed (temporarily) before they are displayed. If one or
more of the optional letters or words follows the switch then only
those type(s) of data will be dumped. The letters and words refer
to the following information:
"=abbrev"
Displays the contents of the .debug_abbrev section.
"=addr"
Displays the contents of the .debug_addr section.
"=frames"
Display the raw contents of a .debug_frame section.
"=gdb_index"
Displays the contents of the .gdb_index and/or .debug_names
sections.
"=info"
Displays the contents of the .debug_info section.
"=info+"
Displays the contents of the .debug_info section, plus any
skeleton unit will be immediately followed by the corresponding
split compile unit (from the .dwo file). To show the
difference between "regular" CUs and split CUs print offsets
and references between { and } instead of [ and ].
"=decodedline"
Displays the interpreted contents of the .debug_line section.
"=macro"
Displays the contents of the .debug_macro and/or .debug_macinfo
sections.
"=loc"
Displays the contents of the .debug_loc and/or .debug_loclists
sections.
"=pubnames"
Displays the contents of the .debug_pubnames and/or
.debug_gnu_pubnames sections.
"=aranges"
Displays the contents of the .debug_aranges section.
"=ranges"
Displays the contents of the .debug_ranges and/or
.debug_rnglists sections.
"=str"
Displays the contents of the .debug_str, .debug_line_str and/or
.debug_str_offsets sections.
Note: displaying the contents of .debug_static_funcs,
.debug_static_vars and debug_weaknames sections is not
currently supported.
-p <number or name>
--string-dump=<number or name>
Displays the contents of the indicated section as printable
strings. A number identifies a particular section by index in
the section table; any other string identifies all sections
with that name in the object file.
-c
--archive-index
Displays the file symbol index information contained in the
header part of binary archives. Performs the same function as
the t command to ar, but without using the BFD library.
Output control
-z
--decompress
Requests that the section(s) being dumped by x, R or p options are
decompressed before being displayed. If the section(s) are not
compressed then they are displayed as is.
-v
--version
Display the version number of eu-readelf.
-W
--wide
Ignored for compatibility (lines always wide).
-H
--help
Display the command line options understood by eu-readelf.
@file
Read command-line options from file. The options read are inserted
in place of the original @file option. If file does not exist, or
cannot be read, then the option will be treated literally, and not
removed.
Options in file are separated by whitespace. A whitespace
character may be included in an option by surrounding the entire
option in either single or double quotes. Any character (including
a backslash) may be included by prefixing the character to be
included with a backslash. The file may itself contain additional
@file options; any such options will be processed recursively.
