elffile...
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.
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.
- --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
- -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.
- -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.
- -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.
