53 objfile...
54
56 objdump displays information about one or more object files. The
57 options control what particular information to display. This
58 information is mostly useful to programmers who are working on the
59 compilation tools, as opposed to programmers who just want their
60 program to compile and work.
61 objfile... are the object files to be examined. When you specify
63 archives, objdump shows information on each of the member object files.
64
66 The long and short forms of options, shown here as alternatives, are
67 equivalent. At least one option from the list
68 -a,-d,-D,-e,-f,-g,-G,-h,-H,-p,-P,-r,-R,-s,-S,-t,-T,-V,-x must be given.
69 -a
71 --archive-header
72 If any of the objfile files are archives, display the archive
73 header information (in a format similar to ls -l). Besides the
74 information you could list with ar tv, objdump -a shows the object
75 file format of each archive member.
76 --adjust-vma=offset
78 When dumping information, first add offset to all the section
79 addresses. This is useful if the section addresses do not
80 correspond to the symbol table, which can happen when putting
81 sections at particular addresses when using a format which can not
82 represent section addresses, such as a.out.
83 -b bfdname
85 --target=bfdname
86 Specify that the object-code format for the object files is
87 bfdname. This option may not be necessary; objdump can
88 automatically recognize many formats.
89 For example,
91 objdump -b oasys -m vax -h fu.o
93 displays summary information from the section headers (-h) of fu.o,
95 which is explicitly identified (-m) as a VAX object file in the
96 format produced by Oasys compilers. You can list the formats
97 available with the -i option.
98 -C
100 --demangle[=style]
101 Decode (demangle) low-level symbol names into user-level names.
102 Besides removing any initial underscore prepended by the system,
103 this makes C++ function names readable. Different compilers have
104 different mangling styles. The optional demangling style argument
105 can be used to choose an appropriate demangling style for your
106 compiler.
107 -g
109 --debugging
110 Display debugging information. This attempts to parse STABS
111 debugging format information stored in the file and print it out
112 using a C like syntax. If no STABS debuging was found this option
113 falls back on the -W option to print any DWARF information in the
114 file.
115 -e
117 --debugging-tags
118 Like -g, but the information is generated in a format compatible
119 with ctags tool.
120 -d
122 --disassemble
123 Display the assembler mnemonics for the machine instructions from
124 objfile. This option only disassembles those sections which are
125 expected to contain instructions.
126 -D
128 --disassemble-all
129 Like -d, but disassemble the contents of all sections, not just
130 those expected to contain instructions.
131 This option also has a subtle effect on the disassembly of
133 instructions in code sections. When option -d is in effect objdump
134 will assume that any symbols present in a code section occur on the
135 boundary between instructions and it will refuse to disassemble
136 across such a boundary. When option -D is in effect however this
137 assumption is supressed. This means that it is possible for the
138 output of -d and -D to differ if, for example, data is stored in
139 code sections.
140 If the target is an ARM architecture this switch also has the
142 effect of forcing the disassembler to decode pieces of data found
143 in code sections as if they were instructions.
144 --prefix-addresses
146 When disassembling, print the complete address on each line. This
147 is the older disassembly format.
148 -EB
150 -EL
151 --endian={big|little}
152 Specify the endianness of the object files. This only affects
153 disassembly. This can be useful when disassembling a file format
154 which does not describe endianness information, such as S-records.
155 -f
157 --file-headers
158 Display summary information from the overall header of each of the
159 objfile files.
160 -F
162 --file-offsets
163 When disassembling sections, whenever a symbol is displayed, also
164 display the file offset of the region of data that is about to be
165 dumped. If zeroes are being skipped, then when disassembly
166 resumes, tell the user how many zeroes were skipped and the file
167 offset of the location from where the disassembly resumes. When
168 dumping sections, display the file offset of the location from
169 where the dump starts.
170 --file-start-context
172 Specify that when displaying interlisted source code/disassembly
173 (assumes -S) from a file that has not yet been displayed, extend
174 the context to the start of the file.
175 -h
177 --section-headers
178 --headers
179 Display summary information from the section headers of the object
180 file.
181 File segments may be relocated to nonstandard addresses, for
183 example by using the -Ttext, -Tdata, or -Tbss options to ld.
184 However, some object file formats, such as a.out, do not store the
185 starting address of the file segments. In those situations,
186 although ld relocates the sections correctly, using objdump -h to
187 list the file section headers cannot show the correct addresses.
188 Instead, it shows the usual addresses, which are implicit for the
189 target.
190 Note, in some cases it is possible for a section to have both the
192 READONLY and the NOREAD attributes set. In such cases the NOREAD
193 attribute takes precedence, but objdump will report both since the
194 exact setting of the flag bits might be important.
195 -H
197 --help
198 Print a summary of the options to objdump and exit.
199 -i
201 --info
202 Display a list showing all architectures and object formats
203 available for specification with -b or -m.
204 -j name
206 --section=name
207 Display information only for section name.
208 -l
210 --line-numbers
211 Label the display (using debugging information) with the filename
212 and source line numbers corresponding to the object code or relocs
213 shown. Only useful with -d, -D, or -r.
214 -m machine
216 --architecture=machine
217 Specify the architecture to use when disassembling object files.
218 This can be useful when disassembling object files which do not
219 describe architecture information, such as S-records. You can list
220 the available architectures with the -i option.
221 If the target is an ARM architecture then this switch has an
223 additional effect. It restricts the disassembly to only those
224 instructions supported by the architecture specified by machine.
225 If it is necessary to use this switch because the input file does
226 not contain any architecture information, but it is also desired to
227 disassemble all the instructions use -marm.
228 -M options
230 --disassembler-options=options
231 Pass target specific information to the disassembler. Only
232 supported on some targets. If it is necessary to specify more than
233 one disassembler option then multiple -M options can be used or can
234 be placed together into a comma separated list.
235 For ARC, dsp controls the printing of DSP instructions, spfp
237 selects the printing of FPX single precision FP instructions, dpfp
238 selects the printing of FPX double precision FP instructions,
239 quarkse_em selects the printing of special QuarkSE-EM instructions,
240 fpuda selects the printing of double precision assist instructions,
241 fpus selects the printing of FPU single precision FP instructions,
242 while fpud selects the printing of FPU double precision FP
243 instructions. Additionally, one can choose to have all the
244 immediates printed in hexadecimal using hex. By default, the short
245 immediates are printed using the decimal representation, while the
246 long immediate values are printed as hexadecimal.
247 cpu=... allows to enforce a particular ISA when disassembling
249 instructions, overriding the -m value or whatever is in the ELF
250 file. This might be useful to select ARC EM or HS ISA, because
251 architecture is same for those and disassembler relies on private
252 ELF header data to decide if code is for EM or HS. This option
253 might be specified multiple times - only the latest value will be
254 used. Valid values are same as for the assembler -mcpu=... option.
255 If the target is an ARM architecture then this switch can be used
257 to select which register name set is used during disassembler.
258 Specifying -M reg-names-std (the default) will select the register
259 names as used in ARM's instruction set documentation, but with
260 register 13 called 'sp', register 14 called 'lr' and register 15
261 called 'pc'. Specifying -M reg-names-apcs will select the name set
262 used by the ARM Procedure Call Standard, whilst specifying -M reg-
263 names-raw will just use r followed by the register number.
264 There are also two variants on the APCS register naming scheme
266 enabled by -M reg-names-atpcs and -M reg-names-special-atpcs which
267 use the ARM/Thumb Procedure Call Standard naming conventions.
268 (Either with the normal register names or the special register
269 names).
270 This option can also be used for ARM architectures to force the
272 disassembler to interpret all instructions as Thumb instructions by
273 using the switch --disassembler-options=force-thumb. This can be
274 useful when attempting to disassemble thumb code produced by other
275 compilers.
276 For AArch64 targets this switch can be used to set whether
278 instructions are disassembled as the most general instruction using
279 the -M no-aliases option or whether instruction notes should be
280 generated as comments in the disasssembly using -M notes.
281 For the x86, some of the options duplicate functions of the -m
283 switch, but allow finer grained control. Multiple selections from
284 the following may be specified as a comma separated string.
285 "x86-64"
287 "i386"
288 "i8086"
289 Select disassembly for the given architecture.
290 "intel"
292 "att"
293 Select between intel syntax mode and AT&T syntax mode.
294 "amd64"
296 "intel64"
297 Select between AMD64 ISA and Intel64 ISA.
298 "intel-mnemonic"
300 "att-mnemonic"
301 Select between intel mnemonic mode and AT&T mnemonic mode.
302 Note: "intel-mnemonic" implies "intel" and "att-mnemonic"
303 implies "att".
304 "addr64"
306 "addr32"
307 "addr16"
308 "data32"
309 "data16"
310 Specify the default address size and operand size. These four
311 options will be overridden if "x86-64", "i386" or "i8086"
312 appear later in the option string.
313 "suffix"
315 When in AT&T mode, instructs the disassembler to print a
316 mnemonic suffix even when the suffix could be inferred by the
317 operands.
318 For PowerPC, the -M argument raw selects disasssembly of hardware
320 insns rather than aliases. For example, you will see "rlwinm"
321 rather than "clrlwi", and "addi" rather than "li". All of the -m
322 arguments for gas that select a CPU are supported. These are: 403,
323 405, 440, 464, 476, 601, 603, 604, 620, 7400, 7410, 7450, 7455,
324 750cl, 821, 850, 860, a2, booke, booke32, cell, com, e200z4, e300,
325 e500, e500mc, e500mc64, e500x2, e5500, e6500, efs, power4, power5,
326 power6, power7, power8, power9, ppc, ppc32, ppc64, ppc64bridge,
327 ppcps, pwr, pwr2, pwr4, pwr5, pwr5x, pwr6, pwr7, pwr8, pwr9, pwrx,
328 titan, and vle. 32 and 64 modify the default or a prior CPU
329 selection, disabling and enabling 64-bit insns respectively. In
330 addition, altivec, any, htm, vsx, and spe add capabilities to a
331 previous or later CPU selection. any will disassemble any opcode
332 known to binutils, but in cases where an opcode has two different
333 meanings or different arguments, you may not see the disassembly
334 you expect. If you disassemble without giving a CPU selection, a
335 default will be chosen from information gleaned by BFD from the
336 object files headers, but the result again may not be as you
337 expect.
338 For MIPS, this option controls the printing of instruction mnemonic
340 names and register names in disassembled instructions. Multiple
341 selections from the following may be specified as a comma separated
342 string, and invalid options are ignored:
343 "no-aliases"
345 Print the 'raw' instruction mnemonic instead of some pseudo
346 instruction mnemonic. I.e., print 'daddu' or 'or' instead of
347 'move', 'sll' instead of 'nop', etc.
348 "msa"
350 Disassemble MSA instructions.
351 "virt"
353 Disassemble the virtualization ASE instructions.
354 "xpa"
356 Disassemble the eXtended Physical Address (XPA) ASE
357 instructions.
358 "gpr-names=ABI"
360 Print GPR (general-purpose register) names as appropriate for
361 the specified ABI. By default, GPR names are selected
362 according to the ABI of the binary being disassembled.
363 "fpr-names=ABI"
365 Print FPR (floating-point register) names as appropriate for
366 the specified ABI. By default, FPR numbers are printed rather
367 than names.
368 "cp0-names=ARCH"
370 Print CP0 (system control coprocessor; coprocessor 0) register
371 names as appropriate for the CPU or architecture specified by
372 ARCH. By default, CP0 register names are selected according to
373 the architecture and CPU of the binary being disassembled.
374 "hwr-names=ARCH"
376 Print HWR (hardware register, used by the "rdhwr" instruction)
377 names as appropriate for the CPU or architecture specified by
378 ARCH. By default, HWR names are selected according to the
379 architecture and CPU of the binary being disassembled.
380 "reg-names=ABI"
382 Print GPR and FPR names as appropriate for the selected ABI.
383 "reg-names=ARCH"
385 Print CPU-specific register names (CP0 register and HWR names)
386 as appropriate for the selected CPU or architecture.
387 For any of the options listed above, ABI or ARCH may be specified
389 as numeric to have numbers printed rather than names, for the
390 selected types of registers. You can list the available values of
391 ABI and ARCH using the --help option.
392 For VAX, you can specify function entry addresses with -M
394 entry:0xf00ba. You can use this multiple times to properly
395 disassemble VAX binary files that don't contain symbol tables (like
396 ROM dumps). In these cases, the function entry mask would
397 otherwise be decoded as VAX instructions, which would probably lead
398 the rest of the function being wrongly disassembled.
399 -p
401 --private-headers
402 Print information that is specific to the object file format. The
403 exact information printed depends upon the object file format. For
404 some object file formats, no additional information is printed.
405 -P options
407 --private=options
408 Print information that is specific to the object file format. The
409 argument options is a comma separated list that depends on the
410 format (the lists of options is displayed with the help).
411 For XCOFF, the available options are:
413 "header"
415 "aout"
416 "sections"
417 "syms"
418 "relocs"
419 "lineno,"
420 "loader"
421 "except"
422 "typchk"
423 "traceback"
424 "toc"
425 "ldinfo"
426 Not all object formats support this option. In particular the ELF
428 format does not use it.
429 -r
431 --reloc
432 Print the relocation entries of the file. If used with -d or -D,
433 the relocations are printed interspersed with the disassembly.
434 -R
436 --dynamic-reloc
437 Print the dynamic relocation entries of the file. This is only
438 meaningful for dynamic objects, such as certain types of shared
439 libraries. As for -r, if used with -d or -D, the relocations are
440 printed interspersed with the disassembly.
441 -s
443 --full-contents
444 Display the full contents of any sections requested. By default
445 all non-empty sections are displayed.
446 -S
448 --source
449 Display source code intermixed with disassembly, if possible.
450 Implies -d.
451 --prefix=prefix
453 Specify prefix to add to the absolute paths when used with -S.
454 --prefix-strip=level
456 Indicate how many initial directory names to strip off the
457 hardwired absolute paths. It has no effect without --prefix=prefix.
458 --show-raw-insn
460 When disassembling instructions, print the instruction in hex as
461 well as in symbolic form. This is the default except when
462 --prefix-addresses is used.
463 --no-show-raw-insn
465 When disassembling instructions, do not print the instruction
466 bytes. This is the default when --prefix-addresses is used.
467 --insn-width=width
469 Display width bytes on a single line when disassembling
470 instructions.
471 -W[lLiaprmfFsoRtUuTgAckK]
473 --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]
474 Displays the contents of the DWARF debug sections in the file, if
475 any are present. Compressed debug sections are automatically
476 decompressed (temporarily) before they are displayed. If one or
477 more of the optional letters or words follows the switch then only
478 those type(s) of data will be dumped. The letters and words refer
479 to the following information:
480 "a"
482 "=abbrev"
483 Displays the contents of the .debug_abbrev section.
484 "A"
486 "=addr"
487 Displays the contents of the .debug_addr section.
488 "c"
490 "=cu_index"
491 Displays the contents of the .debug_cu_index and/or
492 .debug_tu_index sections.
493 "f"
495 "=frames"
496 Display the raw contents of a .debug_frame section.
497 "F"
499 "=frame-interp"
500 Display the interpreted contents of a .debug_frame section.
501 "g"
503 "=gdb_index"
504 Displays the contents of the .gdb_index and/or .debug_names
505 sections.
506 "i"
508 "=info"
509 Displays the contents of the .debug_info section. Note: the
510 output from this option can also be restricted by the use of
511 the --dwarf-depth and --dwarf-start options.
512 "k"
514 "=links"
515 Displays the contents of the .gnu_debuglink and/or
516 .gnu_debugaltlink sections. Also displays the link to a
517 separate dwarf object file (dwo), if one is specified by the
518 DW_AT_GNU_dwo_name or DW_AT_dwo_name attributes in the
519 .debug_info section.
520 "K"
522 "=follow-links"
523 Display the contents of any selected debug sections that are
524 found in a linked, separate debug info file. This can result
525 in multiple versions of the same debug section being displayed
526 if both the main file and the separate debug info file contain
527 sections with the same name.
528 In addition, when displaying DWARF attributes, if a form is
530 found that references the separate debug info file, then the
531 referenced contents will also be displayed.
532 "l"
534 "=rawline"
535 Displays the contents of the .debug_line section in a raw
536 format.
537 "L"
539 "=decodedline"
540 Displays the interpreted contents of the .debug_line section.
541 "m"
543 "=macro"
544 Displays the contents of the .debug_macro and/or .debug_macinfo
545 sections.
546 "o"
548 "=loc"
549 Displays the contents of the .debug_loc and/or .debug_loclists
550 sections.
551 "p"
553 "=pubnames"
554 Displays the contents of the .debug_pubnames and/or
555 .debug_gnu_pubnames sections.
556 "r"
558 "=aranges"
559 Displays the contents of the .debug_aranges section.
560 "R"
562 "=Ranges"
563 Displays the contents of the .debug_ranges and/or
564 .debug_rnglists sections.
565 "s"
567 "=str"
568 Displays the contents of the .debug_str, .debug_line_str and/or
569 .debug_str_offsets sections.
570 "t"
572 "=pubtype"
573 Displays the contents of the .debug_pubtypes and/or
574 .debug_gnu_pubtypes sections.
575 "T"
577 "=trace_aranges"
578 Displays the contents of the .trace_aranges section.
579 "u"
581 "=trace_abbrev"
582 Displays the contents of the .trace_abbrev section.
583 "U"
585 "=trace_info"
586 Displays the contents of the .trace_info section.
587 Note: displaying the contents of .debug_static_funcs,
589 .debug_static_vars and debug_weaknames sections is not currently
590 supported.
591 --dwarf-depth=n
593 Limit the dump of the ".debug_info" section to n children. This is
594 only useful with --debug-dump=info. The default is to print all
595 DIEs; the special value 0 for n will also have this effect.
596 With a non-zero value for n, DIEs at or deeper than n levels will
598 not be printed. The range for n is zero-based.
599 --dwarf-start=n
601 Print only DIEs beginning with the DIE numbered n. This is only
602 useful with --debug-dump=info.
603 If specified, this option will suppress printing of any header
605 information and all DIEs before the DIE numbered n. Only siblings
606 and children of the specified DIE will be printed.
607 This can be used in conjunction with --dwarf-depth.
609 --dwarf-check
611 Enable additional checks for consistency of Dwarf information.
612 -G
614 --stabs
615 Display the full contents of any sections requested. Display the
616 contents of the .stab and .stab.index and .stab.excl sections from
617 an ELF file. This is only useful on systems (such as Solaris 2.0)
618 in which ".stab" debugging symbol-table entries are carried in an
619 ELF section. In most other file formats, debugging symbol-table
620 entries are interleaved with linkage symbols, and are visible in
621 the --syms output.
622 --start-address=address
624 Start displaying data at the specified address. This affects the
625 output of the -d, -r and -s options.
626 --stop-address=address
628 Stop displaying data at the specified address. This affects the
629 output of the -d, -r and -s options.
630 -t
632 --syms
633 Print the symbol table entries of the file. This is similar to the
634 information provided by the nm program, although the display format
635 is different. The format of the output depends upon the format of
636 the file being dumped, but there are two main types. One looks
637 like this:
638 [ 4](sec 3)(fl 0x00)(ty 0)(scl 3) (nx 1) 0x00000000 .bss
640 [ 6](sec 1)(fl 0x00)(ty 0)(scl 2) (nx 0) 0x00000000 fred
641 where the number inside the square brackets is the number of the
643 entry in the symbol table, the sec number is the section number,
644 the fl value are the symbol's flag bits, the ty number is the
645 symbol's type, the scl number is the symbol's storage class and the
646 nx value is the number of auxilary entries associated with the
647 symbol. The last two fields are the symbol's value and its name.
648 The other common output format, usually seen with ELF based files,
650 looks like this:
651 00000000 l d .bss 00000000 .bss
653 00000000 g .text 00000000 fred
654 Here the first number is the symbol's value (sometimes refered to
656 as its address). The next field is actually a set of characters
657 and spaces indicating the flag bits that are set on the symbol.
658 These characters are described below. Next is the section with
659 which the symbol is associated or *ABS* if the section is absolute
660 (ie not connected with any section), or *UND* if the section is
661 referenced in the file being dumped, but not defined there.
662 After the section name comes another field, a number, which for
664 common symbols is the alignment and for other symbol is the size.
665 Finally the symbol's name is displayed.
666 The flag characters are divided into 7 groups as follows:
668 "l"
670 "g"
671 "u"
672 "!" The symbol is a local (l), global (g), unique global (u),
673 neither global nor local (a space) or both global and local
674 (!). A symbol can be neither local or global for a variety of
675 reasons, e.g., because it is used for debugging, but it is
676 probably an indication of a bug if it is ever both local and
677 global. Unique global symbols are a GNU extension to the
678 standard set of ELF symbol bindings. For such a symbol the
679 dynamic linker will make sure that in the entire process there
680 is just one symbol with this name and type in use.
681 "w" The symbol is weak (w) or strong (a space).
683 "C" The symbol denotes a constructor (C) or an ordinary symbol (a
685 space).
686 "W" The symbol is a warning (W) or a normal symbol (a space). A
688 warning symbol's name is a message to be displayed if the
689 symbol following the warning symbol is ever referenced.
690 "I"
692 "i" The symbol is an indirect reference to another symbol (I), a
693 function to be evaluated during reloc processing (i) or a
694 normal symbol (a space).
695 "d"
697 "D" The symbol is a debugging symbol (d) or a dynamic symbol (D) or
698 a normal symbol (a space).
699 "F"
701 "f"
702 "O" The symbol is the name of a function (F) or a file (f) or an
703 object (O) or just a normal symbol (a space).
704 -T
706 --dynamic-syms
707 Print the dynamic symbol table entries of the file. This is only
708 meaningful for dynamic objects, such as certain types of shared
709 libraries. This is similar to the information provided by the nm
710 program when given the -D (--dynamic) option.
711 The output format is similar to that produced by the --syms option,
713 except that an extra field is inserted before the symbol's name,
714 giving the version information associated with the symbol. If the
715 version is the default version to be used when resolving
716 unversioned references to the symbol then it's displayed as is,
717 otherwise it's put into parentheses.
718 --special-syms
720 When displaying symbols include those which the target considers to
721 be special in some way and which would not normally be of interest
722 to the user.
723 -V
725 --version
726 Print the version number of objdump and exit.
727 -x
729 --all-headers
730 Display all available header information, including the symbol
731 table and relocation entries. Using -x is equivalent to specifying
732 all of -a -f -h -p -r -t.
733 -w
735 --wide
736 Format some lines for output devices that have more than 80
737 columns. Also do not truncate symbol names when they are
738 displayed.
739 -z
741 --disassemble-zeroes
742 Normally the disassembly output will skip blocks of zeroes. This
743 option directs the disassembler to disassemble those blocks, just
744 like any other data.
745 @file
747 Read command-line options from file. The options read are inserted
748 in place of the original @file option. If file does not exist, or
749 cannot be read, then the option will be treated literally, and not
750 removed.
751 Options in file are separated by whitespace. A whitespace
753 character may be included in an option by surrounding the entire
754 option in either single or double quotes. Any character (including
755 a backslash) may be included by prefixing the character to be
756 included with a backslash. The file may itself contain additional
757 @file options; any such options will be processed recursively.
