+.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 BFD\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.)

+.PD 0
+.IP "\fB\-\-binary\-architecture=\fR\fIbfdarch\fR" 4
+.IX Item "--binary-architecture=bfdarch"
+.PD
+Useful when transforming a architecture-less input file into an object file.
+In this case the output architecture can be set to \fIbfdarch\fR.  This
+option will be ignored if the input file has a known \fIbfdarch\fR.  You
+can access this binary data inside a program by referencing the special
+symbols that are created by the conversion process.  These symbols are
+called _binary_\fIobjfile\fR_start, _binary_\fIobjfile\fR_end and
+_binary_\fIobjfile\fR_size.  e.g. you can transform a picture file into
+an object file and then access it in your code using these symbols.

+Copy only the indicated sections from the input file to the output file.

+inappropriately may make the output file unusable.  Wildcard

+If the first character of \fIsectionpattern\fR is the exclamation

+.Sp
+.Vb 1

+This option may be given more than once.  Note that using this option
+inappropriately may make the output file unusable.  Wildcard
+characters are accepted in \fIsectionpattern\fR.  Using both the
+\&\fB\-j\fR and \fB\-R\fR options together results in undefined
+behaviour.
+.Sp
+If the first character of \fIsectionpattern\fR is the exclamation

+.Sp
+.Vb 1

+Remove relocations from the output file for any section matching
+\&\fIsectionpattern\fR.  This option may be given more than once.  Note
+that using this option inappropriately may make the output file
+unusable.  Wildcard characters are accepted in \fIsectionpattern\fR.
+For example:
+.Sp
+.Vb 1
+\&          \-\-remove\-relocations=.text.*
+.Ve
+.Sp
+will remove the relocations for all sections matching the patter
+\&'.text.*'.
+.Sp
+If the first character of \fIsectionpattern\fR is the exclamation
+point (!) then matching sections will not have their relocation
+removed even if an earlier use of \fB\-\-remove\-relocations\fR on the

+For example:
+.Sp
+.Vb 1
+\&          \-\-remove\-relocations=.text.* \-\-remove\-relocations=!.text.foo
+.Ve
+.Sp
+will remove all relocations for sections matching the pattern
