(copy_section): Call it. (copy_options, copy_usage, copy_main): Add --byte option to activate it. Appropriate the -b option (which was an undocumented synonym for -F) for it, also. Add --interleave, -i option for additional control. (setup_section, copy_section, mangle_section): Renamed with no `s' on the end. * objcopy.1, binutils.texi: Document the new options. * objdump.c (display_target_tables, display_target_list): New functions broken out of display_info. Eliminate some magic constants. Use more meaningful variable names. (dump_bfd_header): New function broken out of display_bfd. (dump_section_header): New function broken out of dump_headers. (remove_useless_symbols): Don't shadow global variable name with parameter. (objdump_print_address): Fix backward test.

.SH DESCRIPTION
|
|
The GNU
|
|
.B objcopy
|
|
utility copies the contents of an object file to another.
|
|
.B objcopy
|
|
uses the GNU BFD 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
|
|
.B objcopy
|
|
is controlled by command-line options.
|
|
.PP
|
|
.B objcopy
|
|
creates temporary files to do its translations and deletes them
|
|
afterward.
|
|
.B objcopy
|
|
uses BFD to do all its translation work; it knows about all the
|
|
formats BFD knows about, and thus is able to recognize most formats
|
|
without being told explicitly.
|
|
.PP
|
|
.I infile
|
|
and
|
|
.I outfile
|
|
are the source and output files respectively. If you do not specify
|
|
.IR outfile ,
|
|
.B objcopy
|
|
creates a temporary file and destructively renames the result with the
|
|
name of the input file.
|
|
|
|
.SH OPTIONS
|
|
.TP
|
|
.B \-I \fIbfdname\fR, \fB\-\-input\-target=\fIbfdname
|
|
Consider the source file's object format to be
|
|
.IR bfdname ,
|
|
rather than attempting to deduce it.
|
|
.TP
|
|
.B \-O \fIbfdname\fR, \fB\-\-output\-target=\fIbfdname
|
|
Write the output file using the object format
|
|
.IR bfdname .
|
|
.TP
|
|
.B \-F \fIbfdname\fR, \fB\-\-target=\fIbfdname
|
|
Use
|
|
.I bfdname
|
|
as the object format for both the input and the output file; i.e.
|
|
simply transfer data from source to destination with no translation.
|
|
.TP
|
|
.B \-S\fR, \fB\-\-strip\-all
|
|
Do not copy relocation and symbol information from the source file.
|
|
.TP
|
|
.B \-g\fR, \fB\-\-strip\-debug
|
|
Do not copy debugging symbols from the source file.
|
|
.TP
|
|
.B \-x\fR, \fB \-\-discard\-all
|
|
Do not copy non-global symbols from the source file.
|
|
.TP
|
|
.B \-X\fR, \fB\-\-discard\-locals
|
|
Do not copy compiler-generated local symbols. (These usually start
|
|
with "L" or ".").
|
|
.TP
|
|
.B \-b \fIbyte\fR, \fB\-\-byte=\fIbyte
|
|
Keep only every \fIbyte\fPth byte of the input file (header data is
|
|
not affected). \fIbyte\fP can be in the range from 0 to the
|
|
interleave-1. This option is useful for creating files to program
|
|
ROMs. It is typically used with an srec output target.
|
|
.TP
|
|
.B \-i \fIinterleave\fR, \fB\-\-interleave=\fIinterleave
|
|
Only copy one out of every \fIinterleave\fP bytes. Which one to copy is
|
|
selected by the \fB\-b\fP or \fB\-\-byte\fP option. The default is 4.
|
|
The interleave is ignored if neither \fB\-b\fP nor \fB\-\-byte\fP is given.
|
|
.TP
|
|
.B \-v\fR, \fB\-\-verbose
|
|
Verbose output: list all object files modified. In the case of
|
|
archives, "\fBobjcopy \-V\fR" lists all members of the archive.
|
|
.TP
|
|
.B \-V\fR, \fB\-\-version
|
|
Show the version number of
|
|
.B objcopy
|
|
and exit.
|
|
.TP
|
|
.B \-\-help
|
|
Show a summary of the options to
|
|
.B objcopy
|
|
and exit.
