               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 infinite 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 debugging 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.

       --no-addresses
           When disassembling, don't print addresses on each line or for symbols
           and relocation offsets.  In combination with --no-show-raw-insn this
           may be useful for comparing compiler output.

       --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 one 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.

           "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 and also for a limited set of instructions when
               in Intel mode, instructs the disassembler to print a mnemonic
               suffix even when the suffix could be inferred by the operands or,
               for certain instructions, the execution mode's defaults.

           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, power10, ppc, ppc32, ppc64, ppc64bridge, ppcps, pwr,
           pwr2, pwr4, pwr5, pwr5x, pwr6, pwr7, pwr8, pwr9, pwr10, 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[lLiaprmfFsoORtUuTgAckK]
       --dwarf[=rawline,=decodedline,=info,=abbrev,=pubnames,=aranges,=macro,=frames,=frames-interp,=str,=str-offsets,=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.

           "O"
           "=str-offsets"
               Displays the contents of the .debug_str_offsets section.

           "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 auxiliary 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 referred 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.
