objfile...
DESCRIPTION
objdump displays information about one or more object files. The
options control what particular information to display. This
information is mostly useful to programmers who are working on the
compilation tools, as opposed to programmers who just want their
program to compile and work.
objfile... are the object files to be examined. When you specify
archives, objdump shows information on each of the member object files.
OPTIONS
The long and short forms of options, shown here as alternatives, are
equivalent. At least one option from the list
-a,-d,-D,-e,-f,-g,-G,-h,-H,-p,-P,-r,-R,-s,-S,-t,-T,-V,-x must be given.
-a
--archive-header
If any of the objfile files are archives, display the archive
header information (in a format similar to ls -l). Besides the
information you could list with ar tv, objdump -a shows the object
file format of each archive member.
--adjust-vma=offset
When dumping information, first add offset to all the section
addresses. This is useful if the section addresses do not
correspond to the symbol table, which can happen when putting
sections at particular addresses when using a format which can not
represent section addresses, such as a.out.
-b bfdname
--target=bfdname
Specify that the object-code format for the object files is
bfdname. This option may not be necessary; objdump can
automatically recognize many formats.
For example,
objdump -b oasys -m vax -h fu.o
displays summary information from the section headers (-h) of fu.o,
which is explicitly identified (-m) as a VAX object file in the
format produced by Oasys compilers. You can list the formats
available with the -i option.
-C
--demangle[=style]
Decode (demangle) low-level symbol names into user-level names.
Besides removing any initial underscore prepended by the system,
this makes C++ function names readable. Different compilers have
different mangling styles. The optional demangling style argument
can be used to choose an appropriate demangling style for your
compiler.
--recurse-limit
--no-recurse-limit
--recursion-limit
--no-recursion-limit
Enables or disables a limit on the amount of recursion performed
whilst demangling strings. Since the name mangling formats allow
for an inifinite level of recursion it is possible to create
strings whose decoding will exhaust the amount of stack space
available on the host machine, triggering a memory fault. The
limit tries to prevent this from happening by restricting recursion
to 2048 levels of nesting.
The default is for this limit to be enabled, but disabling it may
be necessary in order to demangle truly complicated names. Note
however that if the recursion limit is disabled then stack
exhaustion is possible and any bug reports about such an event will
be rejected.
-g
--debugging
Display debugging information. This attempts to parse STABS
debugging format information stored in the file and print it out
using a C like syntax. If no STABS debuging was found this option
falls back on the -W option to print any DWARF information in the
file.
-e
--debugging-tags
Like -g, but the information is generated in a format compatible
with ctags tool.
-d
--disassemble
--disassemble=symbol
Display the assembler mnemonics for the machine instructions from
the input file. This option only disassembles those sections which
are expected to contain instructions. If the optional symbol
argument is given, then display the assembler mnemonics starting at
symbol. If symbol is a function name then disassembly will stop at
the end of the function, otherwise it will stop when the next
symbol is encountered. If there are no matches for symbol then
nothing will be displayed.
Note if the --dwarf=follow-links option has also been enabled then
any symbol tables in linked debug info files will be read in and
used when disassembling.
-D
--disassemble-all
Like -d, but disassemble the contents of all sections, not just
those expected to contain instructions.
This option also has a subtle effect on the disassembly of
instructions in code sections. When option -d is in effect objdump
will assume that any symbols present in a code section occur on the
boundary between instructions and it will refuse to disassemble
across such a boundary. When option -D is in effect however this
assumption is supressed. This means that it is possible for the
output of -d and -D to differ if, for example, data is stored in
code sections.
If the target is an ARM architecture this switch also has the
effect of forcing the disassembler to decode pieces of data found
in code sections as if they were instructions.
Note if the --dwarf=follow-links option has also been enabled then
any symbol tables in linked debug info files will be read in and
used when disassembling.
--prefix-addresses
When disassembling, print the complete address on each line. This
is the older disassembly format.
-EB
-EL
--endian={big|little}
Specify the endianness of the object files. This only affects
disassembly. This can be useful when disassembling a file format
which does not describe endianness information, such as S-records.
-f
--file-headers
Display summary information from the overall header of each of the
objfile files.
-F
--file-offsets
When disassembling sections, whenever a symbol is displayed, also
display the file offset of the region of data that is about to be
dumped. If zeroes are being skipped, then when disassembly
resumes, tell the user how many zeroes were skipped and the file
offset of the location from where the disassembly resumes. When
dumping sections, display the file offset of the location from
where the dump starts.
--file-start-context
Specify that when displaying interlisted source code/disassembly
(assumes -S) from a file that has not yet been displayed, extend
the context to the start of the file.
-h
--section-headers
--headers
Display summary information from the section headers of the object
file.
File segments may be relocated to nonstandard addresses, for
example by using the -Ttext, -Tdata, or -Tbss options to ld.
However, some object file formats, such as a.out, do not store the
starting address of the file segments. In those situations,
although ld relocates the sections correctly, using objdump -h to
list the file section headers cannot show the correct addresses.
Instead, it shows the usual addresses, which are implicit for the
target.
Note, in some cases it is possible for a section to have both the
READONLY and the NOREAD attributes set. In such cases the NOREAD
attribute takes precedence, but objdump will report both since the
exact setting of the flag bits might be important.
-H
--help
Print a summary of the options to objdump and exit.
-i
--info
Display a list showing all architectures and object formats
available for specification with -b or -m.
-j name
--section=name
Display information only for section name.
-l
--line-numbers
Label the display (using debugging information) with the filename
and source line numbers corresponding to the object code or relocs
shown. Only useful with -d, -D, or -r.
-m machine
--architecture=machine
Specify the architecture to use when disassembling object files.
This can be useful when disassembling object files which do not
describe architecture information, such as S-records. You can list
the available architectures with the -i option.
If the target is an ARM architecture then this switch has an
additional effect. It restricts the disassembly to only those
instructions supported by the architecture specified by machine.
If it is necessary to use this switch because the input file does
not contain any architecture information, but it is also desired to
disassemble all the instructions use -marm.
-M options
--disassembler-options=options
Pass target specific information to the disassembler. Only
supported on some targets. If it is necessary to specify more than
one disassembler option then multiple -M options can be used or can
be placed together into a comma separated list.
For ARC, dsp controls the printing of DSP instructions, spfp
selects the printing of FPX single precision FP instructions, dpfp
selects the printing of FPX double precision FP instructions,
quarkse_em selects the printing of special QuarkSE-EM instructions,
fpuda selects the printing of double precision assist instructions,
fpus selects the printing of FPU single precision FP instructions,
while fpud selects the printing of FPU double precision FP
instructions. Additionally, one can choose to have all the
immediates printed in hexadecimal using hex. By default, the short
immediates are printed using the decimal representation, while the
long immediate values are printed as hexadecimal.
cpu=... allows to enforce a particular ISA when disassembling
instructions, overriding the -m value or whatever is in the ELF
file. This might be useful to select ARC EM or HS ISA, because
architecture is same for those and disassembler relies on private
ELF header data to decide if code is for EM or HS. This option
might be specified multiple times - only the latest value will be
used. Valid values are same as for the assembler -mcpu=... option.
If the target is an ARM architecture then this switch can be used
to select which register name set is used during disassembler.
Specifying -M reg-names-std (the default) will select the register
names as used in ARM's instruction set documentation, but with
register 13 called 'sp', register 14 called 'lr' and register 15
called 'pc'. Specifying -M reg-names-apcs will select the name set
used by the ARM Procedure Call Standard, whilst specifying -M reg-
names-raw will just use r followed by the register number.
There are also two variants on the APCS register naming scheme
enabled by -M reg-names-atpcs and -M reg-names-special-atpcs which
use the ARM/Thumb Procedure Call Standard naming conventions.
(Either with the normal register names or the special register
names).
This option can also be used for ARM architectures to force the
disassembler to interpret all instructions as Thumb instructions by
using the switch --disassembler-options=force-thumb. This can be
useful when attempting to disassemble thumb code produced by other
compilers.
For AArch64 targets this switch can be used to set whether
instructions are disassembled as the most general instruction using
the -M no-aliases option or whether instruction notes should be
generated as comments in the disasssembly using -M notes.
For the x86, some of the options duplicate functions of the -m
switch, but allow finer grained control. Multiple selections from
the following may be specified as a comma separated string.
"x86-64"
"i386"
"i8086"
Select disassembly for the given architecture.
"intel"
"att"
Select between intel syntax mode and AT&T syntax mode.
"amd64"
"intel64"
Select between AMD64 ISA and Intel64 ISA.
"intel-mnemonic"
"att-mnemonic"
Select between intel mnemonic mode and AT&T mnemonic mode.
Note: "intel-mnemonic" implies "intel" and "att-mnemonic"
implies "att".
"addr64"
"addr32"
"addr16"
"data32"
"data16"
Specify the default address size and operand size. These five
options will be overridden if "x86-64", "i386" or "i8086"
appear later in the option string.
"suffix"
When in AT&T mode, instructs the disassembler to print a
mnemonic suffix even when the suffix could be inferred by the
operands.
For PowerPC, the -M argument raw selects disasssembly of hardware
insns rather than aliases. For example, you will see "rlwinm"
rather than "clrlwi", and "addi" rather than "li". All of the -m
arguments for gas that select a CPU are supported. These are: 403,
405, 440, 464, 476, 601, 603, 604, 620, 7400, 7410, 7450, 7455,
750cl, 821, 850, 860, a2, booke, booke32, cell, com, e200z4, e300,
e500, e500mc, e500mc64, e500x2, e5500, e6500, efs, power4, power5,
power6, power7, power8, power9, ppc, ppc32, ppc64, ppc64bridge,
ppcps, pwr, pwr2, pwr4, pwr5, pwr5x, pwr6, pwr7, pwr8, pwr9, pwrx,
titan, and vle. 32 and 64 modify the default or a prior CPU
selection, disabling and enabling 64-bit insns respectively. In
addition, altivec, any, htm, vsx, and spe add capabilities to a
previous or later CPU selection. any will disassemble any opcode
known to binutils, but in cases where an opcode has two different
meanings or different arguments, you may not see the disassembly
you expect. If you disassemble without giving a CPU selection, a
default will be chosen from information gleaned by BFD from the
object files headers, but the result again may not be as you
expect.
For MIPS, this option controls the printing of instruction mnemonic
names and register names in disassembled instructions. Multiple
selections from the following may be specified as a comma separated
string, and invalid options are ignored:
"no-aliases"
Print the 'raw' instruction mnemonic instead of some pseudo
instruction mnemonic. I.e., print 'daddu' or 'or' instead of
'move', 'sll' instead of 'nop', etc.
"msa"
Disassemble MSA instructions.
"virt"
Disassemble the virtualization ASE instructions.
"xpa"
Disassemble the eXtended Physical Address (XPA) ASE
instructions.
"gpr-names=ABI"
Print GPR (general-purpose register) names as appropriate for
the specified ABI. By default, GPR names are selected
according to the ABI of the binary being disassembled.
"fpr-names=ABI"
Print FPR (floating-point register) names as appropriate for
the specified ABI. By default, FPR numbers are printed rather
than names.
"cp0-names=ARCH"
Print CP0 (system control coprocessor; coprocessor 0) register
names as appropriate for the CPU or architecture specified by
ARCH. By default, CP0 register names are selected according to
the architecture and CPU of the binary being disassembled.
"hwr-names=ARCH"
Print HWR (hardware register, used by the "rdhwr" instruction)
names as appropriate for the CPU or architecture specified by
ARCH. By default, HWR names are selected according to the
architecture and CPU of the binary being disassembled.
"reg-names=ABI"
Print GPR and FPR names as appropriate for the selected ABI.
"reg-names=ARCH"
Print CPU-specific register names (CP0 register and HWR names)
as appropriate for the selected CPU or architecture.
For any of the options listed above, ABI or ARCH may be specified
as numeric to have numbers printed rather than names, for the
selected types of registers. You can list the available values of
ABI and ARCH using the --help option.
For VAX, you can specify function entry addresses with -M
entry:0xf00ba. You can use this multiple times to properly
disassemble VAX binary files that don't contain symbol tables (like
ROM dumps). In these cases, the function entry mask would
otherwise be decoded as VAX instructions, which would probably lead
the rest of the function being wrongly disassembled.
-p
--private-headers
Print information that is specific to the object file format. The
exact information printed depends upon the object file format. For
some object file formats, no additional information is printed.
-P options
--private=options
Print information that is specific to the object file format. The
argument options is a comma separated list that depends on the
format (the lists of options is displayed with the help).
For XCOFF, the available options are:
"header"
"aout"
"sections"
"syms"
"relocs"
"lineno,"
"loader"
"except"
"typchk"
"traceback"
"toc"
"ldinfo"
Not all object formats support this option. In particular the ELF
format does not use it.
-r
--reloc
Print the relocation entries of the file. If used with -d or -D,
the relocations are printed interspersed with the disassembly.
-R
--dynamic-reloc
Print the dynamic relocation entries of the file. This is only
meaningful for dynamic objects, such as certain types of shared
libraries. As for -r, if used with -d or -D, the relocations are
printed interspersed with the disassembly.
-s
--full-contents
Display the full contents of any sections requested. By default
all non-empty sections are displayed.
-S
--source
Display source code intermixed with disassembly, if possible.
Implies -d.
--source-comment[=txt]
Like the -S option, but all source code lines are displayed with a
prefix of txt. Typically txt will be a comment string which can be
used to distinguish the assembler code from the source code. If
txt is not provided then a default string of "# " (hash followed by
a space), will be used.
--prefix=prefix
Specify prefix to add to the absolute paths when used with -S.
--prefix-strip=level
Indicate how many initial directory names to strip off the
hardwired absolute paths. It has no effect without --prefix=prefix.
--show-raw-insn
When disassembling instructions, print the instruction in hex as
well as in symbolic form. This is the default except when
--prefix-addresses is used.
--no-show-raw-insn
When disassembling instructions, do not print the instruction
bytes. This is the default when --prefix-addresses is used.
--insn-width=width
Display width bytes on a single line when disassembling
instructions.
--visualize-jumps[=color|=extended-color|=off]
Visualize jumps that stay inside a function by drawing ASCII art
between the start and target addresses. The optional =color
argument adds color to the output using simple terminal colors.
Alternatively the =extended-color argument will add color using
8bit colors, but these might not work on all terminals.
If it is necessary to disable the visualize-jumps option after it
has previously been enabled then use visualize-jumps=off.
-W[lLiaprmfFsoRtUuTgAckK]
--dwarf[=rawline,=decodedline,=info,=abbrev,=pubnames,=aranges,=macro,=frames,=frames-interp,=str,=loc,=Ranges,=pubtypes,=trace_info,=trace_abbrev,=trace_aranges,=gdb_index,=addr,=cu_index,=links,=follow-links]
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:
"a"
"=abbrev"
Displays the contents of the .debug_abbrev section.
"A"
"=addr"
Displays the contents of the .debug_addr section.
"c"
"=cu_index"
Displays the contents of the .debug_cu_index and/or
.debug_tu_index sections.
"f"
"=frames"
Display the raw contents of a .debug_frame section.
"F"
"=frame-interp"
Display the interpreted contents of a .debug_frame section.
"g"
"=gdb_index"
Displays the contents of the .gdb_index and/or .debug_names
sections.
"i"
"=info"
Displays the contents of the .debug_info section. Note: the
output from this option can also be restricted by the use of
the --dwarf-depth and --dwarf-start options.
"k"
"=links"
Displays the contents of the .gnu_debuglink and/or
.gnu_debugaltlink sections. Also displays any links to
separate dwarf object files (dwo), if they are specified by the
DW_AT_GNU_dwo_name or DW_AT_dwo_name attributes in the
.debug_info section.
"K"
"=follow-links"
Display the contents of any selected debug sections that are
found in linked, separate debug info file(s). This can result
in multiple versions of the same debug section being displayed
if it exists in more than one file.
In addition, when displaying DWARF attributes, if a form is
found that references the separate debug info file, then the
referenced contents will also be displayed.
"l"
"=rawline"
Displays the contents of the .debug_line section in a raw
format.
"L"
"=decodedline"
Displays the interpreted contents of the .debug_line section.
"m"
"=macro"
Displays the contents of the .debug_macro and/or .debug_macinfo
sections.
"o"
"=loc"
Displays the contents of the .debug_loc and/or .debug_loclists
sections.
"p"
"=pubnames"
Displays the contents of the .debug_pubnames and/or
.debug_gnu_pubnames sections.
"r"
"=aranges"
Displays the contents of the .debug_aranges section.
"R"
"=Ranges"
Displays the contents of the .debug_ranges and/or
.debug_rnglists sections.
"s"
"=str"
Displays the contents of the .debug_str, .debug_line_str and/or
.debug_str_offsets sections.
"t"
"=pubtype"
Displays the contents of the .debug_pubtypes and/or
.debug_gnu_pubtypes sections.
"T"
"=trace_aranges"
Displays the contents of the .trace_aranges section.
"u"
"=trace_abbrev"
Displays the contents of the .trace_abbrev section.
"U"
"=trace_info"
Displays the contents of the .trace_info section.
Note: displaying the contents of .debug_static_funcs,
.debug_static_vars and debug_weaknames sections is not currently
supported.
--dwarf-depth=n
Limit the dump of the ".debug_info" section to n children. This is
only useful with --debug-dump=info. The default is to print all
DIEs; the special value 0 for n will also have this effect.
With a non-zero value for n, DIEs at or deeper than n levels will
not be printed. The range for n is zero-based.
--dwarf-start=n
Print only DIEs beginning with the DIE numbered n. This is only
useful with --debug-dump=info.
If specified, this option will suppress printing of any header
information and all DIEs before the DIE numbered n. Only siblings
and children of the specified DIE will be printed.
This can be used in conjunction with --dwarf-depth.
--dwarf-check
Enable additional checks for consistency of Dwarf information.
--ctf=section
Display the contents of the specified CTF section. CTF sections
themselves contain many subsections, all of which are displayed in
order.
--ctf-parent=section
Specify the name of another section from which the CTF dictionary
can inherit types. (If none is specified, we assume the CTF
dictionary inherits types from the default-named member of the
archive contained within this section.)
-G
--stabs
Display the full contents of any sections requested. Display the
contents of the .stab and .stab.index and .stab.excl sections from
an ELF file. This is only useful on systems (such as Solaris 2.0)
in which ".stab" debugging symbol-table entries are carried in an
ELF section. In most other file formats, debugging symbol-table
entries are interleaved with linkage symbols, and are visible in
the --syms output.
--start-address=address
Start displaying data at the specified address. This affects the
output of the -d, -r and -s options.
--stop-address=address
Stop displaying data at the specified address. This affects the
output of the -d, -r and -s options.
-t
--syms
Print the symbol table entries of the file. This is similar to the
information provided by the nm program, although the display format
is different. The format of the output depends upon the format of
the file being dumped, but there are two main types. One looks
like this:
[ 4](sec 3)(fl 0x00)(ty 0)(scl 3) (nx 1) 0x00000000 .bss
[ 6](sec 1)(fl 0x00)(ty 0)(scl 2) (nx 0) 0x00000000 fred
where the number inside the square brackets is the number of the
entry in the symbol table, the sec number is the section number,
the fl value are the symbol's flag bits, the ty number is the
symbol's type, the scl number is the symbol's storage class and the
nx value is the number of auxilary entries associated with the
symbol. The last two fields are the symbol's value and its name.
The other common output format, usually seen with ELF based files,
looks like this:
00000000 l d .bss 00000000 .bss
00000000 g .text 00000000 fred
Here the first number is the symbol's value (sometimes refered to
as its address). The next field is actually a set of characters
and spaces indicating the flag bits that are set on the symbol.
These characters are described below. Next is the section with
which the symbol is associated or *ABS* if the section is absolute
(ie not connected with any section), or *UND* if the section is
referenced in the file being dumped, but not defined there.
After the section name comes another field, a number, which for
common symbols is the alignment and for other symbol is the size.
Finally the symbol's name is displayed.
The flag characters are divided into 7 groups as follows:
"l"
"g"
"u"
"!" The symbol is a local (l), global (g), unique global (u),
neither global nor local (a space) or both global and local
(!). A symbol can be neither local or global for a variety of
reasons, e.g., because it is used for debugging, but it is
probably an indication of a bug if it is ever both local and
global. Unique global symbols are a GNU extension to the
standard set of ELF symbol bindings. For such a symbol the
dynamic linker will make sure that in the entire process there
is just one symbol with this name and type in use.
"w" The symbol is weak (w) or strong (a space).
"C" The symbol denotes a constructor (C) or an ordinary symbol (a
space).
"W" The symbol is a warning (W) or a normal symbol (a space). A
warning symbol's name is a message to be displayed if the
symbol following the warning symbol is ever referenced.
"I"
"i" The symbol is an indirect reference to another symbol (I), a
function to be evaluated during reloc processing (i) or a
normal symbol (a space).
"d"
"D" The symbol is a debugging symbol (d) or a dynamic symbol (D) or
a normal symbol (a space).
"F"
"f"
"O" The symbol is the name of a function (F) or a file (f) or an
object (O) or just a normal symbol (a space).
-T
--dynamic-syms
Print the dynamic symbol table entries of the file. This is only
meaningful for dynamic objects, such as certain types of shared
libraries. This is similar to the information provided by the nm
program when given the -D (--dynamic) option.
The output format is similar to that produced by the --syms option,
except that an extra field is inserted before the symbol's name,
giving the version information associated with the symbol. If the
version is the default version to be used when resolving
unversioned references to the symbol then it's displayed as is,
otherwise it's put into parentheses.
--special-syms
When displaying symbols include those which the target considers to
be special in some way and which would not normally be of interest
to the user.
-V
--version
Print the version number of objdump and exit.
-x
--all-headers
Display all available header information, including the symbol
table and relocation entries. Using -x is equivalent to specifying
all of -a -f -h -p -r -t.
-w
--wide
Format some lines for output devices that have more than 80
columns. Also do not truncate symbol names when they are
displayed.
-z
--disassemble-zeroes
Normally the disassembly output will skip blocks of zeroes. This
option directs the disassembler to disassemble those blocks, just
like any other data.
@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.
