.SH DESCRIPTION
\c
.B objdump\c
\& 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.
.SH OPTIONS
Where long and short forms of an option are shown together, they are
equivalent.

.TP
.IR  "objfile" .\|.\|.
The object files to be examined.  When you specify archives,
\c
.B objdump\c
\& shows information on each of the member object files.

.TP
.B \-a
If any files from \c
.I objfile\c
\& are archives, display the archive
header information (in a format similar to `\|\c
.B ls \-l\c
\|').  Besides the
information you could list with `\|\c
.B ar tv\c
\|', `\|\c
.B objdump \-a\c
\|' shows
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
\c
.I bfdname\c
\&.  This may not be necessary; \c
.I objdump\c
\& can
automatically recognize many formats.  For example,
.sp
.br
objdump\ \-b\ oasys\ \-m\ vax\ \-h\ fu.o
.br
.sp

Displays summary information from the section headers (`\|\c
.B \-h\c
\|') of
`\|\c
.B fu.o\c
\|', which is explicitly identified (`\|\c
.B \-m\c
\|') as a Vax object
file in the format produced by Oasys compilers.  You can list the
formats available with the `\|\c
.B \-i\c
\|' option.

.TP
.B \-d
Disassemble.  Display the assembler mnemonics for the machine
instructions from \c
.I objfile\c
\&.

.TP
.B \-f
File header.  Display summary information from the overall header of
each file in \c
.I objfile\c
\&.

.TP
.B \-h
.TP
.B \-\-header
Header.  Display summary information from the section headers of the
object file.

.TP
.B \-i
Display a list showing all architectures and object formats available
for specification with \c
.B \-b\c
\& or \c
.B \-m\c
\&.

.TP
.BI "-j " "name"\c
\&
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
.BI "-m " "machine"\c
\&
Specify the object files \c
.I objfile\c
\& are for architecture
\c
.I machine\c
\&.  You can list available architectures using the `\|\c
.B \-i\c
\|'
option. 

.TP
.B \-r
.TP
.B \-\-reloc
Relocation.  Print the relocation entries of the file.

.TP
.B \-s
Display the full contents of any sections requested.

.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
.B \-t
.TP
.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 \-x
Display all available header information, including the symbol table and
relocation entries.  Using `\|\c
.B \-x\c
\|' is equivalent to specifying all of
`\|\c
.B \-a \-f \-h \-r \-t\c
\|'.
