	       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.

       -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 file can
	   inherit types.

       -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.
