 .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
 .B objcopy
 can be used to generate S-records by using an output target of
 .B srec
 (e.g., use
 .B -O srec).
 .PP
 .B objcopy
 can be used to generate a raw binary file by using an output target of
 .B binary
 (e.g., use
 .B -O binary).
 When
 .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.  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 -S
 to remove sections containing debugging information.  In some cases
 .B -R
 will be useful to remove sections which contain information which is
 not needed by the binary file.
 .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 \-j \fIsectionname\fR, \fB\-\-only\-section=\fIsectionname
 Copy only the named section from the input file to the output file,
 discarding all other sections.  This option may be given more than
 once.  Note that using this option inappropriately may make the output
 file unusable.
 .TP
 .B \-R \fIsectionname\fR, \fB\-\-remove-section=\fIsectionname
 Remove the named section from the file.  This option may be given more
 than once.  Note that using this option inappropriately may make the
 output file unusable.
 .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 \-\-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.
 .TP
 .B \-L \fIsymbolname\fR, \fB\-\-localize\-symbol=\fIsymbolname
 Make symbol \fIsymbolname\fP local to the file, so that it is not
 visible externally.  This option may be given more than once.
 .TP
 .B \-W \fIsymbolname\fR, \fB\-\-weaken\-symbol=\fIsymbolname
 Make symbol \fIsymbolname\fP weak. This option may be given more than once.
 .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 \-p\fR, \fB\-\-preserve\-dates
 Set the access and modification dates of the output file to be the same
 as those of the input file.
 .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 operation applies to
 the \fIload address\fP (LMA) of the sections.  It 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 load 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.
 .TP
 .B \fB\-\-change\-start=\fIincr\fR, \fB\-\-adjust\-start=\fIincr
 Changes the start address by adding \fIincr\fP.  Not all object file
 formats support setting the start address.
 .TP
 .B \fB\-\-change\-addresses=\fIincr\fR, \fB\-\-adjust\-vma=\fIincr
 Changes the address of all sections, as well as the start address, by
 adding \fIincr\fP.  Some object file formats do not permit section
 addresses to be changed arbitrarily.  Note that this does not relocate
 the sections; if the program expects sections to be loaded at a
 certain address, and this option is used to change the sections such
 that they are loaded at a different address, the program may fail.
 .TP
 .B \fB\-\-change\-section\-address=\fIsection{=,+,-}val\fR, \fB\-\-adjust\-section\-vma=\fIsection{=,+,-}val
 Set or changes the VMA and LMA addresses of the named \fIsection\fP.
 If \fI=\fP is used, the section address is set to \fIval\fP.
 Otherwise, \fIval\fP is added to or subtracted from the section
 address.  See the comments under \fB\-\-change\-addresses\fP, above.  If
 \fIsection\fP does not exist in the input file, a warning will be
 issued, unless \fB\-\-no\-change\-warnings\fP is used.
 .TP
 .B \fB\-\-change\-section\-lma=\fIsection{=,+,-}val
 Set or change the LMA address of the named \fIsection\fP.  If \fI=\fP is
 used, the section address is set to \fIval\fP.  Otherwise, \fIval\fP
 is added to or subtracted from the section address.  See the comments
 under \fB\-\-change\-addresses\fP, above.  If \fIsection\fP does not exist
 in the input file, a warning will be issued, unless
 \fB\-\-no\-change\-warnings\fP is used.
 .TP
 .B \fB\-\-change\-section\-vma=\fIsection{=,+,-}val
 Set or change the VMA address of the named \fIsection\fP.  If \fI=\fP is
 used, the section address is set to \fIval\fP.  Otherwise, \fIval\fP
 is added to or subtracted from the section address.  See the comments
 under \fB\-\-change\-addresses\fP, above.  If \fIsection\fP does not exist
 in the input file, a warning will be issued, unless
 \fB\-\-no\-change\-warnings\fP is used.
 .TP
 .B \fB\-\-change\-warnings\fR, \fB\-\-adjust\-warnings
 If \fB\-\-change\-section\-XXX\fP is used, and the named section does
 not exist, issue a warning.  This is the default.
 .TP
 .B \fB\-\-no\-change\-warnings\fR, \fB\-\-no\-adjust\-warnings
 Do not issue a warning if \fB\-\-change\-section\-XXX\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 \-\-change\-leading\-char
 Some object file formats use special characters at the start of
 symbols.  The most common such character is underscore, which compilers
 often add before every symbol.  This option tells
 .B objcopy
 to change the leading character of every symbol when it converts
 between object file formats.  If the object file formats use the same
 leading character, this option has no effect.  Otherwise, it will add
 a character, or remove a character, or change a character, as
 appropriate.
 .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.  This is different from
 \fB\-\-change\-leading\-char\fP because it always changes the symbol name
 when appropriate, regardless of the object file format of the output
 .TP
 .B \-\-weaken
 Change all global symbols in the file to be weak.
 .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.

	that they are loaded at a different address, the program may fail.
	.TP
	.B \fB\-\-change\-section\-address=\fIsection{=,+,-}val\fR, \fB\-\-adjust\-section\-vma=\fIsection{=,+,-}val
	Set or changes the VMA and LMA addresses of the named \fIsection\fP.
	If \fI=\fP is used, the section address is set to \fIval\fP.
	Otherwise, \fIval\fP is added to or subtracted from the section
	address. See the comments under \fB\-\-change\-addresses\fP, above. If
	\fIsection\fP does not exist in the input file, a warning will be
	issued, unless \fB\-\-no\-change\-warnings\fP is used.
	.TP
	.B \fB\-\-change\-section\-lma=\fIsection{=,+,-}val
	Set or change the LMA address of the named \fIsection\fP. If \fI=\fP is
	used, the section address is set to \fIval\fP. Otherwise, \fIval\fP
	is added to or subtracted from the section address. See the comments
	under \fB\-\-change\-addresses\fP, above. If \fIsection\fP does not exist
	in the input file, a warning will be issued, unless
	\fB\-\-no\-change\-warnings\fP is used.
	.TP
	.B \fB\-\-change\-section\-vma=\fIsection{=,+,-}val
	Set or change the VMA address of the named \fIsection\fP. If \fI=\fP is
	used, the section address is set to \fIval\fP. Otherwise, \fIval\fP
	is added to or subtracted from the section address. See the comments
	under \fB\-\-change\-addresses\fP, above. If \fIsection\fP does not exist
	in the input file, a warning will be issued, unless
	\fB\-\-no\-change\-warnings\fP is used.
	.TP
	.B \fB\-\-change\-warnings\fR, \fB\-\-adjust\-warnings
	If \fB\-\-change\-section\-XXX\fP is used, and the named section does
	not exist, issue a warning. This is the default.
	.TP
	.B \fB\-\-no\-change\-warnings\fR, \fB\-\-no\-adjust\-warnings
	Do not issue a warning if \fB\-\-change\-section\-XXX\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 \-\-change\-leading\-char
	Some object file formats use special characters at the start of
	symbols. The most common such character is underscore, which compilers
	often add before every symbol. This option tells
	.B objcopy
	to change the leading character of every symbol when it converts
	between object file formats. If the object file formats use the same
	leading character, this option has no effect. Otherwise, it will add
	a character, or remove a character, or change a character, as
	appropriate.
	.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. This is different from
	\fB\-\-change\-leading\-char\fP because it always changes the symbol name
	when appropriate, regardless of the object file format of the output
	.TP
	.B \-\-weaken
	Change all global symbols in the file to be weak.
	.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.
