.B objcopy
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. By default, the memory dump will start
-at virtual address zero; the
-.B --set-start
-option may be used to specify a different starting point.
+information will be discarded. The memory dump will start at the
+virtual 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
.B \-g\fR, \fB\-\-strip\-debug
Do not copy debugging symbols from the source file.
.TP
+.B \-\-strip\-unneeded
+Strip all symbols that are not needed for relocation processing.
+.TP
+.B \-K \fIsymbolname\fR, \fB\-\-keep\-symbol=\fIsymbolname
+Copy only symbol \fIsymbolname\fP from the source file. This option
+may be given more than once.
+.TP
+.B \-N \fIsymbolname\fR, \fB\-\-strip\-symbol=\fIsymbolname
+Do not copy symbol \fIsymbolname\fP from the source file. This option
+may be given more than once, and may be combined with strip options
+other than \fB\-K\fR.
+.TP
.B \-x\fR, \fB \-\-discard\-all
Do not copy non-global symbols from the source file.
.TP
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 \-\-debugging
+Convert debugging information, if possible. This is not the default
+because only certain debugging formats are supported, and the
+conversion process can be time consuming.
+.TP
+.B \-\-gap\-fill=\fIval
+Fill gaps between sections with \fIval\fP. This is done by increasing
+the size of the section with the lower address, and filling in the extra
+space created with \fIval\fP.
+.TP
+.B \-\-pad\-to=\fIaddress
+Pad the output file up to the virtual address \fIaddress\fP. This is
+done by increasing the size of the last section. The extra space is
+filled in with the value specified by \fB\-\-gap\-fill\fP (default
+zero).
+.TP
.B \fB\-\-set\-start=\fIval
Set the start address of the new file to \fIval\fP. Not all object
-file formats support setting the start address. When using the
-\fBbinary\fP output file format, the start address sets the virtual
-address of the first byte in the binary output file.
+file formats support setting the start address.
.TP
.B \fB\-\-adjust\-start=\fIincr
Adjust the start address by adding \fIincr\fP. Not all object file
Do not issue a warning if \fB\-\-adjust\-section\-vma\fP is used, even
if the named section does not exist.
.TP
+.B \fB\-\-set\-section\-flags=\fIsection=flags
+Set the flags for the named section. The \fIflags\fP argument is a
+comma separated string of flag names. The recognized names are
+\fIalloc\fP, \fIload\fP, \fIreadonly\fP, \fIcode\fP, \fIdata\fP, and
+\fIrom\fP. Not all flags are meaningful for all object file
+formats.
+.TP
+.B \fB\-\-add\-section=\fIsectionname=filename
+Add a new section named \fIsectionname\fR while copying the file. The
+contents of the new section are taken from the file \fIfilename\fR.
+The size of the section will be the size of the file. This option
+only works on file formats which can support sections with arbitrary
+names.
+.TP
+.B \-\-remove\-leading\-char
+If the first character of a global symbol is a special symbol leading
+character used by the object file format, remove the character. The
+most common symbol leading character is underscore. This option will
+remove a leading underscore from all global symbols. This can be useful
+if you want to link together objects of different file formats with
+different conventions for symbol names.
+.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.
