.SH "DESCRIPTION"
|
||||
.IX Header "DESCRIPTION"
|
||||
The \s-1GNU\s0 \fBobjcopy\fR utility copies the contents of an object
|
||||
file to another. \fBobjcopy\fR uses the \s-1GNU\s0 \s-1BFD\s0 Library to
|
||||
read and write the object files. It can write the destination object
|
||||
file in a format different from that of the source object file. The
|
||||
exact behavior of \fBobjcopy\fR is controlled by command-line options.
|
||||
Note that \fBobjcopy\fR should be able to copy a fully linked file
|
||||
between any two formats. However, copying a relocatable object file
|
||||
between any two formats may not work as expected.
|
||||
.PP
|
||||
\&\fBobjcopy\fR creates temporary files to do its translations and
|
||||
deletes them afterward. \fBobjcopy\fR uses \s-1BFD\s0 to do all its
|
||||
translation work; it has access to all the formats described in \s-1BFD\s0
|
||||
and thus is able to recognize most formats without being told
|
||||
explicitly.
|
||||
.PP
|
||||
\&\fBobjcopy\fR can be used to generate S\-records by using an output
|
||||
target of \fBsrec\fR (e.g., use \fB\-O srec\fR).
|
||||
.PP
|
||||
\&\fBobjcopy\fR can be used to generate a raw binary file by using an
|
||||
output target of \fBbinary\fR (e.g., use \fB\-O binary\fR). When
|
||||
\&\fBobjcopy\fR generates a raw binary file, it will essentially produce
|
||||
a memory dump of the contents of the input object file. All symbols and
|
||||
relocation information will be discarded. The memory dump will start at
|
||||
the load address of the lowest section copied into the output file.
|
||||
.PP
|
||||
When generating an S\-record or a raw binary file, it may be helpful to
|
||||
use \fB\-S\fR to remove sections containing debugging information. In
|
||||
some cases \fB\-R\fR will be useful to remove sections which contain
|
||||
information that is not needed by the binary file.
|
||||
.PP
|
||||
Note\-\-\-\fBobjcopy\fR is not able to change the endianness of its input
|
||||
files. If the input format has an endianness (some formats do not),
|
||||
\&\fBobjcopy\fR can only copy the inputs into file formats that have the
|
||||
same endianness or which have no endianness (e.g., \fBsrec\fR).
|
||||
(However, see the \fB\-\-reverse\-bytes\fR option.)

In this case the output architecture can be set to \fIbfdarch\fR. This

called _binary_\fIobjfile\fR_start, _binary_\fIobjfile\fR_end and

Rename a section from \fIoldname\fR to \fInewname\fR, optionally

.IX Item "--weaken-symbols=filename"
|

Apply \fB\-\-weaken\-symbol\fR option to each symbol listed in the file
|

\&\fIfilename\fR. \fIfilename\fR is simply a flat file, with one symbol

.IP "\fB\-\-alt\-machine\-code=\fR\fIindex\fR" 4

.IX Item "--alt-machine-code=index"
|

If the output architecture has alternate machine codes, use the
|
||||
\&\fIindex\fRth code instead of the default one. This is useful in case
|
||||
a machine is assigned an official code and the tool-chain adopts the
|
||||
new code, but other applications still depend on the original code
|
||||
being used. For \s-1ELF\s0 based architectures if the \fIindex\fR
|
||||
alternative does not exist then the value is treated as an absolute
|
||||
number to be stored in the e_machine field of the \s-1ELF\s0 header.
|

.IP "\fB\-\-writable\-text\fR" 4
|

.IP "\fB\-\-keep\-file\-symbols\fR" 4
|

.IX Item "--keep-file-symbols"
|
||||
When stripping a file, perhaps with \fB\-\-strip\-debug\fR or
|
||||
\&\fB\-\-strip\-unneeded\fR, retain any symbols specifying source file names,
|
||||
which would otherwise get stripped.
|
||||
.IP "\fB\-\-only\-keep\-debug\fR" 4
|
||||
.IX Item "--only-keep-debug"
|
||||
Strip a file, removing contents of any sections that would not be
|
||||
stripped by \fB\-\-strip\-debug\fR and leaving the debugging sections
|
||||
intact. In \s-1ELF\s0 files, this preserves all note sections in the output.
|
||||
.Sp
|
||||
The intention is that this option will be used in conjunction with
|
||||
\&\fB\-\-add\-gnu\-debuglink\fR to create a two part executable. One a
|
||||
stripped binary which will occupy less space in \s-1RAM\s0 and in a
|
||||
distribution and the second a debugging information file which is only
|
||||
needed if debugging abilities are required. The suggested procedure
|
||||
to create these files is as follows:

to add a link to the debugging info into the stripped executable.

Note \- the choice of \f(CW\*(C`.dbg\*(C'\fR as an extension for the debug info
|

file is arbitrary. Also the \f(CW\*(C`\-\-only\-keep\-debug\*(C'\fR step is
|

optional. You could instead do this:

i.e., the file pointed to by the \fB\-\-add\-gnu\-debuglink\fR can be the

full executable. It does not have to be a file created by the

\&\fB\-\-only\-keep\-debug\fR switch.

.Sp
|
||||
Note \- this switch is only intended for use on fully linked files. It
|
||||
does not make sense to use it on object files where the debugging
|
||||
information may be incomplete. Besides the gnu_debuglink feature
|
||||
currently only supports the presence of one filename containing
|

debugging information, not multiple filenames on a one-per-object-file

basis.

used in \s-1ARM\s0's instruction set documentation, but with register 13 called

\&'sp', register 14 called 'lr' and register 15 called 'pc'. Specifying

use the ARM/Thumb Procedure Call Standard naming conventions. (Either

This option can also be used for \s-1ARM\s0 architectures to force the

disassembler to interpret all instructions as Thumb instructions by

useful when attempting to disassemble thumb code produced by other

\&\fBx86\-64\fR, \fBi386\fR or \fBi8086\fR appear later in the

option string. Lastly, \fBsuffix\fR, when in \s-1AT&T\s0 mode,
|

instructs the disassembler to print a mnemonic suffix even when the

suffix could be inferred by the operands.

.Sp
|

For \s-1PPC\s0, \fBbooke\fR, \fBbooke32\fR and \fBbooke64\fR select

disassembly of BookE instructions. \fB32\fR and \fB64\fR select

PowerPC and PowerPC64 disassembly, respectively. \fBe300\fR selects

disassembly for the e300 family. \fB440\fR selects disassembly for

the PowerPC 440.

Display the full contents of any sections requested. Display the
|
||||
contents of the .stab and .stab.index and .stab.excl sections from an
|
||||
\&\s-1ELF\s0 file. This is only useful on systems (such as Solaris 2.0) in which
|
||||
\&\f(CW\*(C`.stab\*(C'\fR debugging symbol-table entries are carried in an \s-1ELF\s0
|
||||
section. In most other file formats, debugging symbol-table entries are
|
||||
interleaved with linkage symbols, and are visible in the \fB\-\-syms\fR
|

output.
|

of the \fB\-d\fR, \fB\-r\fR and \fB\-s\fR options.
|
||||
.IP "\fB\-\-stop\-address=\fR\fIaddress\fR" 4
|

.PD
|

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 \fBnm\fR
|
||||
program when given the \fB\-D\fR (\fB\-\-dynamic\fR) option.
|
||||
.IP "\fB\-\-special\-syms\fR" 4
|

Normally the disassembly output will skip blocks of zeroes. This
|

option directs the disassembler to disassemble those blocks, just like
|

any other data.
|

.IP "\fB@\fR\fIfile\fR" 4
|
||||
.IX Item "@file"
|
||||
Read command-line options from \fIfile\fR. The options read are
|
||||
inserted in place of the original @\fIfile\fR option. If \fIfile\fR
|
||||
does not exist, or cannot be read, then the option will be treated
|
||||
literally, and not removed.
|
||||
.Sp
|
||||
Options in \fIfile\fR are separated by whitespace. A whitespace
|
||||
character may be included in an option by surrounding the entire
|
||||
option in either single or double quotes. Any character (including a
|
||||
backslash) may be included by prefixing the character to be included
|
||||
with a backslash. The \fIfile\fR may itself contain additional
|
||||
@\fIfile\fR options; any such options will be processed recursively.
