objfile... are the object files to be examined. When youspecify archives, objdump shows information on each of the memberobject files.OPTIONSThe long and short forms of options, shown here as alternatives, areequivalent. At least one option from the list-a,-d,-D,-e,-f,-g,-G,-h,-H,-p,-r,-R,-s,-S,-t,-T,-V,-x must be given.TagDescription-a--archive-headerIf any of the objfile files are archives, display the archiveheader information (in a format similar to ls -l). Besides theinformation you could list with ar tv, objdump -a showsthe object file format of each archive member.--adjust-vma=offsetWhen dumping information, first add offset to all the sectionaddresses. This is useful if the section addresses do not correspond tothe symbol table, which can happen when putting sections at particularaddresses when using a format which can not represent section addresses,such as a.out.-b bfdname--target=bfdnameSpecify that the object-code format for the object files isbfdname. This option may not be necessary; objdump canautomatically recognize many formats.For example, objdump -b oasys -m vax -h fu.odisplays summary information from the section headers (-h) offu.o, which is explicitly identified (-m) as a VAX objectfile in the format produced by Oasys compilers. You can list theformats 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, thismakes C++ function names readable. Different compilers have differentmangling styles. The optional demangling style argument can be used tochoose an appropriate demangling style for your compiler.-g--debuggingDisplay debugging information. This attempts to parse debugginginformation stored in the file and print it out using a C like syntax.Only certain types of debugging information have been implemented.Some other types are supported by readelf -w.-e--debugging-tagsLike -g, but the information is generated in a format compatiblewith ctags tool.-d--disassembleDisplay the assembler mnemonics for the machine instructions fromobjfile. This option only disassembles those sections which areexpected to contain instructions.-D--disassemble-allLike -d, but disassemble the contents of all sections, not justthose expected to contain instructions.--prefix-addressesWhen disassembling, print the complete address on each line. This isthe older disassembly format.-EB-EL--endian={big|little}Specify the endianness of the object files. This only affectsdisassembly. This can be useful when disassembling a file format whichdoes not describe endianness information, such as S-records.-f--file-headersDisplay summary information from the overall header ofeach of the objfile files.--file-start-contextSpecify that when displaying interlisted source code/disassembly(assumes -S) from a file that has not yet been displayed, extend thecontext to the start of the file.-h--section-headers--headersDisplay summary information from the section headers of theobject file.File segments may be relocated to nonstandard addresses, for example byusing the -Ttext, -Tdata, or -Tbss options told. However, some object file formats, such as a.out, do notstore 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 thetarget.-H--helpPrint a summary of the options to objdump and exit.-i--infoDisplay a list showing all architectures and object formats availablefor specification with -b or -m.-j name--section=nameDisplay information only for section name.-l--line-numbersLabel the display (using debugging information) with the filename andsource line numbers corresponding to the object code or relocs shown.Only useful with -d, -D, or -r.-m machine--architecture=machineSpecify the architecture to use when disassembling object files. Thiscan be useful when disassembling object files which do not describearchitecture information, such as S-records. You can list the availablearchitectures with the -i option.-M options--disassembler-options=optionsPass target specific information to the disassembler. Only supported onsome targets. If it is necessary to specify more than onedisassembler option then multiple -M options can be used orcan be placed together into a comma separated list.If the target is an ARM architecture then this switch can be used toselect which register name set is used during disassembler. Specifying-M reg-names-std (the default) will select the register names asused in ARMs instruction set documentation, but with register 13 calledsp, register 14 called lr and register 15 called pc. Specifying-M reg-names-apcs will select the name set used by the ARMProcedure Call Standard, whilst specifying -M reg-names-raw willjust use r followed by the register number.There are also two variants on the APCS register naming scheme enabledby -M reg-names-atpcs and -M reg-names-special-atpcs whichuse the ARM/Thumb Procedure Call Standard naming conventions. (Eitherwith the normal register names or the special register names).This option can also be used for ARM architectures to force thedisassembler to interpret all instructions as Thumb instructions byusing the switch --disassembler-options=force-thumb. This can beuseful when attempting to disassemble thumb code produced by othercompilers.For the x86, some of the options duplicate functions of the -mswitch, but allow finer grained control. Multiple selections from thefollowing may be specified as a comma separated string.x86-64, i386 and i8086 select disassembly forthe given architecture. intel and att select betweenintel syntax mode and AT&T syntax mode. addr32,addr16, data32 and data16 specify the defaultaddress size and operand size. These four options will be overridden ifx86-64, i386 or i8086 appear later in theoption string. Lastly, suffix, when in AT&T mode,instructs the disassembler to print a mnemonic suffix even when thesuffix could be inferred by the operands.For PPC, booke, booke32 and booke64 selectdisassembly of BookE instructions. 32 and 64 selectPowerPC and PowerPC64 disassembly, respectively. e300 selectsdisassembly for the e300 family.For MIPS, this option controls the printing of instruction mnemonicnames and register names in disassembled instructions. Multipleselections from the following may be specified as a comma separatedstring, and invalid options are ignored:TagDescriptionno-aliasesPrint the raw instruction mnemonic instead of some pseudoinstruction mnemonic. I.e., print daddu or or instead of move,sll instead of nop, etc.gpr-names=ABIPrint GPR (general-purpose register) names as appropriatefor the specified ABI. By default, GPR names are selected according tothe ABI of the binary being disassembled.fpr-names=ABIPrint FPR (floating-point register) names asappropriate for the specified ABI. By default, FPR numbers are printedrather than names.cp0-names=ARCHPrint CP0 (system control coprocessor; coprocessor 0) register namesas appropriate for the CPU or architecture specified byARCH. By default, CP0 register names are selected according tothe architecture and CPU of the binary being disassembled.hwr-names=ARCHPrint HWR (hardware register, used by the rdhwr instruction) namesas appropriate for the CPU or architecture specified byARCH. By default, HWR names are selected according tothe architecture and CPU of the binary being disassembled.reg-names=ABIPrint GPR and FPR names as appropriate for the selected ABI.reg-names=ARCHPrint 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 orARCH may be specified as numeric to have numbers printedrather than names, for the selected types of registers.You can list the available values of ABI and ARCH usingthe --help option.For VAX, you can specify function entry addresses with -Mentry:0xf00ba. You can use this multiple times to properlydisassemble VAX binary files that dont contain symbol tables (likeROM dumps). In these cases, the function entry mask would otherwisebe decoded as VAX instructions, which would probably lead the restof the function being wrongly disassembled.-p--private-headersPrint information that is specific to the object file format. The exactinformation printed depends upon the object file format. For someobject file formats, no additional information is printed.-r--relocPrint the relocation entries of the file. If used with -d or-D, the relocations are printed interspersed with thedisassembly.-R--dynamic-relocPrint the dynamic relocation entries of the file. This is onlymeaningful for dynamic objects, such as certain types of sharedlibraries.-s--full-contentsDisplay the full contents of any sections requested. By default allnon-empty sections are displayed.-S--sourceDisplay source code intermixed with disassembly, if possible. Implies-d.--show-raw-insnWhen disassembling instructions, print the instruction in hex as well asin symbolic form. This is the default except when--prefix-addresses is used.--no-show-raw-insnWhen disassembling instructions, do not print the instruction bytes.This is the default when --prefix-addresses is used.-W--dwarfDisplays the contents of the DWARF debug sections in the file, if anyare present.-G--stabsDisplay the full contents of any sections requested. Display thecontents of the .stab and .stab.index and .stab.excl sections from anELF file. This is only useful on systems (such as Solaris 2.0) in which.stab debugging symbol-table entries are carried in an ELFsection. In most other file formats, debugging symbol-table entries areinterleaved with linkage symbols, and are visible in the --symsoutput.--start-address=addressStart displaying data at the specified address. This affects the outputof the -d, -r and -s options.--stop-address=addressStop displaying data at the specified address. This affects the outputof the -d, -r and -s options.-t--symsPrint the symbol table entries of the file.This is similar to the information provided by the nm program.-T--dynamic-symsPrint the dynamic symbol table entries of the file. This is onlymeaningful for dynamic objects, such as certain types of sharedlibraries. This is similar to the information provided by the nmprogram when given the -D (--dynamic) option.--special-symsWhen displaying symbols include those which the target considers to bespecial in some way and which would not normally be of interest to theuser.-V--versionPrint the version number of objdump and exit.-x--all-headersDisplay all available header information, including the symbol table andrelocation entries. Using -x is equivalent to specifying all of-a -f -h -p -r -t.-w--wideFormat some lines for output devices that have more than 80 columns.Also do not truncate symbol names when they are displayed.-z--disassemble-zeroesNormally the disassembly output will skip blocks of zeroes. Thisoption directs the disassembler to disassemble those blocks, just likeany other data.@fileRead command-line options from file. The options read areinserted in place of the original @file option. If filedoes not exist, or cannot be read, then the option will be treatedliterally, and not removed. Options in file are separated by whitespace. A whitespacecharacter may be included in an option by surrounding the entireoption in either single or double quotes. Any character (including abackslash) may be included by prefixing the character to be includedwith a backslash. The file may itself contain additional@file options; any such options will be processed recursively.SEE ALSOnm(1), readelf(1), and the Info entries for binutils.COPYRIGHTCopyright (c) 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999,2000, 2001, 2002, 2003, 2004, 2005, 2006 Free Software Foundation, Inc.Permission is granted to copy, distribute and/or modify this documentunder the terms of the GNU Free Documentation License, Version 1.1or any later version published by the Free Software Foundation;with no Invariant Sections, with no Front-Cover Texts, and with noBack-Cover Texts.
