.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.
|
|
.PP
|
|
.IR "objfile" .\|.\|.
|
|
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
|
|
must be given.
|
|
|
|
.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
|
|
\&
|
|
Specify the object-code format for the object files to be
|
|
\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
|
|
|
|
display 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 \-\-help
|
|
Print a summary of the options to
|
|
.B objdump
|
|
and exit.
|
|
|
|
.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 \-\-version
|
|
Print the version number of
|
|
.B objdump
|
|
and exit.
|
|
|
|
.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
|
|
\|'.
