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.

-The object files to be examined. When you specify archives,

+are the object files to be examined. When you specify archives,
\c
.B objdump\c
\& shows information on each of the member object files.
+.SH OPTIONS
+Where long and short forms of an option are shown together, they are
+equivalent. At least one option besides
+.B \-l
+(\fB\-\-line\-numbers\fP) must be given.
+
.TP
.B \-a
+.TP
+.B \-\-archive\-headers
If any files from \c
-.I objfiles\c
+.I objfile\c
\& are archives, display the archive
header information (in a format similar to `\|\c
.B ls \-l\c
the object file format of each archive member.
.TP
-.BI "-b " "bfdname"\c
-\&
-You can specify a particular object-code format for your object files as
+.BI "\-\-adjust\-vma=" "offset"
+When dumping information, first add
+.I 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.
+
+.TP
+.BI "\-b " "bfdname"\c
+.TP
+.BI "\-\-target=" "bfdname"
+Specify the object-code format for the object files to be

.B \-i\c
\|' option.
+.TP
+.B \-C
+.TP
+.B \-\-demangle
+Decode (\fIdemangle\fP) low-level symbol names into user-level names.
+Besides removing any initial underscore prepended by the system, this
+makes C++ function names readable.
+
+.TP
+.B \-\-debugging
+Display debugging information. This attempts to parse debugging
+information stored in the file and print it out using a C like syntax.
+Only certain types of debugging information have been implemented.
+
.TP
.B \-d
-Disassemble. Display the assembler mnemonics for the machine
+.TP
+.B \-\-disassemble
+Display the assembler mnemonics for the machine
instructions from \c
-.I objfiles\c
+.I objfile\c
\&.
+This option only disassembles those sections which are
+expected to contain instructions.
+
+.TP
+.B \-D
+.TP
+.B \-\-disassemble-all
+Like \fB\-d\fP, but disassemble the contents of all sections, not just
+those expected to contain instructions.
+
+.TP
+.B \-\-prefix\-addresses
+When disassembling, print the complete address on each line. This is
+the older disassembly format.
+
+.TP
+.B \-\-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.
+
+.TP
+.B \-EB
+.TP
+.B \-EL
+.TP
+.BI "\-\-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.
.TP
.B \-f
-File header. Display summary information from the overall header of
+.TP
+.B \-\-file\-headers
+Display summary information from the overall header of
each file in \c
-.I objfiles\c
+.I objfile\c
\&.
.TP
.B \-h
.TP
-.B +header
-Header. Display summary information from the section headers of the
+.B \-\-section\-headers
+.TP
+.B \-\-headers
+Display summary information from the section headers of the
object file.
+.TP
+.B \-\-help
+Print a summary of the options to
+.B objdump
+and exit.
+
.TP
.B \-i
+.TP
+.B \-\-info
Display a list showing all architectures and object formats available
for specification with \c
.B \-b\c
\&.
.TP
-.BI "-j " "name"\c
-\&
+.BI "\-j " "name"\c
+.TP
+.BI "\-\-section=" "name"
Display information only for section \c
.I name\c
-\&
+\&.
.TP
.B \-l
-Label the display (using debugging information) with the source filename
-and line numbers corresponding to the object code shown.
+.TP
+.B \-\-line\-numbers
+Label the display (using debugging information) with the filename
+and source line numbers corresponding to the object code shown.
+Only useful with \fB\-d\fP, \fB\-D\fP, or \fB\-r\fP.
.TP
-.BI "-m " "machine"\c
-\&
-Specify the object files \c
-.I objfiles\c
-\& are for architecture
-\c
-.I machine\c
-\&. You can list available architectures using the `\|\c
-.B \-i\c
-\|'
-option.
+.BI "\-m " "machine"\c
+.TP
+.BI "\-\-architecture=" "machine"
+Specify the architecture to use when disassembling object files. This
+can be useful when disasembling object files which do not describe
+architecture information, such as S-records. You can list the available
+architectures with the \fB\-i\fP option.
.TP
.B \-r
.TP
-.B +reloc
-Relocation. Print the relocation entries of the file.
+.B \-\-reloc
+Print the relocation entries of the file. If used with \fB\-d\fP or
+\fB\-d\fP, the relocations are printed interspersed with the
+disassembly.
+
+.TP
+.B \-R
+.TP
+.B \-\-dynamic\-reloc
+Print the dynamic relocation entries of the file. This is only
+meaningful for dynamic objects, such as certain types of shared
+libraries.
.TP
.B \-s
+.TP
+.B \-\-full\-contents
Display the full contents of any sections requested.
+.TP
+.B \-S
+.TP
+.B \-\-source
+Display source code intermixed with disassembly, if possible. Implies
+\fB-d\fP.
+
+.TP
+.B \-\-show\-raw\-insn
+When disassembling instructions, print the instruction in hex as well as
+in symbolic form. This is the default except when
+.B \-\-prefix\-addresses
+is used.
+
+.TP
+.B \-\-no\-show\-raw\-insn
+When disassembling instructions, do not print the instruction bytes.
+This is the default when
+.B \-\-prefix\-addresses
+is used.
+
+.TP
+.B \-\-stabs
+Display the contents of the .stab, .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.
+
+.TP
+.BI "\-\-start\-address=" "address"
+Start displaying data at the specified address. This affects the output
+of the
+.B \-d\c
+,
+.B \-r
+and
+.B \-s
+options.
+
+.TP
+.BI "\-\-stop\-address=" "address"
+Stop displaying data at the specified address. This affects the output
+of the
+.B \-d\c
+,
+.B \-r
+and
+.B \-s
+options.
+
.TP
.B \-t
.TP
-.B +syms
+.B \-\-syms
Symbol Table. Print the symbol table entries of the file.
This is similar to the information provided by the `\|\c
.B nm\c
\|' program.
+.TP
+.B \-T
+.TP
+.B \-\-dynamic\-syms
+Dynamic Symbol Table. 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 `\|\c
+.B nm\c
+\|' program when given the
+.B \-D (\-\-dynamic)
+option.
+
+.TP
+.B \-\-version
+Print the version number of
+.B objdump
+and exit.
+
.TP
.B \-x
+.TP
+.B \-\-all\-headers
Display all available header information, including the symbol table and
relocation entries. Using `\|\c
