DESCRIPTION
       The GNU objcopy utility copies the contents of an object file to
       another.  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 objcopy is
       controlled by command-line options.  Note that objcopy 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.

       objcopy creates temporary files to do its translations and deletes them
       afterward.  objcopy uses BFD to do all its translation work; it has
       access to all the formats described in BFD and thus is able to
       recognize most formats without being told explicitly.

       objcopy can be used to generate S-records by using an output target of
       srec (e.g., use -O srec).

       objcopy can be used to generate a raw binary file by using an output
       target of binary (e.g., use -O binary).  When 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 load address of the
       lowest section copied into the output file.

       When generating an S-record or a raw binary file, it may be helpful to
       use -S to remove sections containing debugging information.  In some
       cases -R will be useful to remove sections which contain information
       that is not needed by the binary file.

       Note---objcopy is not able to change the endianness of its input files.
       If the input format has an endianness (some formats do not), objcopy
       can only copy the inputs into file formats that have the same
       endianness or which have no endianness (e.g., srec).  (However, see the
       --reverse-bytes option.)

OPTIONS
       infile
       outfile
           The input and output files, respectively.  If you do not specify
           outfile, objcopy creates a temporary file and destructively renames
           the result with the name of infile.

       -I bfdname
       --input-target=bfdname
           Consider the source file's object format to be bfdname, rather than
           attempting to deduce it.

       -O bfdname
       --output-target=bfdname
           Write the output file using the object format bfdname.

       -F bfdname
       --target=bfdname
           Use 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.

       -B bfdarch
       --binary-architecture=bfdarch
           Useful when transforming a architecture-less input file into an
           object file.  In this case the output architecture can be set to
           bfdarch.  This option will be ignored if the input file has a known
           bfdarch.  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_objfile_start,
           _binary_objfile_end and _binary_objfile_size.  e.g. you can
           transform a picture file into an object file and then access it in
           your code using these symbols.

       -j sectionpattern
       --only-section=sectionpattern
           Copy only the indicated sections from the input file to the output
           file.  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 sectionpattern.

       -R sectionpattern
       --remove-section=sectionpattern
           Remove any section matching sectionpattern from the output file.
           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 sectionpattern.  Using both the -j and
           -R options together results in undefined behaviour.

       -S
       --strip-all
           Do not copy relocation and symbol information from the source file.

       -g
       --strip-debug
           Do not copy debugging symbols or sections from the source file.

       --strip-unneeded
           Strip all symbols that are not needed for relocation processing.

       -K symbolname
       --keep-symbol=symbolname
           When stripping symbols, keep symbol symbolname even if it would
           normally be stripped.  This option may be given more than once.

       -N symbolname
       --strip-symbol=symbolname
           Do not copy symbol symbolname from the source file.  This option
           may be given more than once.

       --strip-unneeded-symbol=symbolname
           Do not copy symbol symbolname from the source file unless it is
           needed by a relocation.  This option may be given more than once.

       -G symbolname
       --keep-global-symbol=symbolname
           Keep only symbol symbolname global.  Make all other symbols local
           to the file, so that they are not visible externally.  This option
           may be given more than once.

       --localize-hidden
           In an ELF object, mark all symbols that have hidden or internal
           visibility as local.  This option applies on top of symbol-specific
           localization options such as -L.

       -L symbolname
       --localize-symbol=symbolname
           Make symbol symbolname local to the file, so that it is not visible
           externally.  This option may be given more than once.

       -W symbolname
       --weaken-symbol=symbolname
           Make symbol symbolname weak. This option may be given more than
           once.

       --globalize-symbol=symbolname
           Give symbol symbolname global scoping so that it is visible outside
           of the file in which it is defined.  This option may be given more
           than once.

       -w
       --wildcard
           Permit regular expressions in symbolnames used in other command
           line options.  The question mark (?), asterisk (*), backslash (\)
           and square brackets ([]) operators can be used anywhere in the
           symbol name.  If the first character of the symbol name is the
           exclamation point (!) then the sense of the switch is reversed for
           that symbol.  For example:

                     -w -W !foo -W fo*

           would cause objcopy to weaken all symbols that start with "fo"
           except for the symbol "foo".

       -x
       --discard-all
           Do not copy non-global symbols from the source file.

       -X
       --discard-locals
           Do not copy compiler-generated local symbols.  (These usually start
           with L or ..)

       -b byte
       --byte=byte
           If interleaving has been enabled via the --interleave option then
           start the range of bytes to keep at the byteth byte.  byte can be
           in the range from 0 to breadth-1, where breadth is the value given
           by the --interleave option.

       -i [breadth]
       --interleave[=breadth]
           Only copy a range out of every breadth bytes.  (Header data is not
           affected).  Select which byte in the range begins the copy with the
           --byte option.  Select the width of the range with the
           --interleave-width option.

           This option is useful for creating files to program ROM.  It is
           typically used with an "srec" output target.  Note that objcopy
           will complain if you do not specify the --byte option as well.

           The default interleave breadth is 4, so with --byte set to 0,
           objcopy would copy the first byte out of every four bytes from the
           input to the output.

       --interleave-width=width
           When used with the --interleave option, copy width bytes at a time.
           The start of the range of bytes to be copied is set by the --byte
           option, and the extent of the range is set with the --interleave
           option.

           The default value for this option is 1.  The value of width plus
           the byte value set by the --byte option must not exceed the
           interleave breadth set by the --interleave option.

           This option can be used to create images for two 16-bit flashes
           interleaved in a 32-bit bus by passing -b 0 -i 4
           --interleave-width=2 and -b 2 -i 4 --interleave-width=2 to two
           objcopy commands.  If the input was '12345678' then the outputs
           would be '1256' and '3478' respectively.

       -p
       --preserve-dates
           Set the access and modification dates of the output file to be the
           same as those of the input file.

       -D
       --enable-deterministic-archives
           Operate in deterministic mode.  When copying archive members and
           writing the archive index, use zero for UIDs, GIDs, timestamps, and
           use consistent file modes for all files.

           If binutils was configured with --enable-deterministic-archives,
           then this mode is on by default.  It can be disabled with the -U
           option, below.

       -U
       --disable-deterministic-archives
           Do not operate in deterministic mode.  This is the inverse of the
           -D option, above: when copying archive members and writing the
           archive index, use their actual UID, GID, timestamp, and file mode
           values.

           This is the default unless binutils was configured with
           --enable-deterministic-archives.

       --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.

       --gap-fill val
           Fill gaps between sections with val.  This operation applies to the
           load address (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 val.

       --pad-to address
           Pad the output file up to the load address address.  This is done
           by increasing the size of the last section.  The extra space is
           filled in with the value specified by --gap-fill (default zero).

       --set-start val
           Set the start address of the new file to val.  Not all object file
           formats support setting the start address.

       --change-start incr
       --adjust-start incr
           Change the start address by adding incr.  Not all object file
           formats support setting the start address.

       --change-addresses incr
       --adjust-vma incr
           Change the VMA and LMA addresses of all sections, as well as the
           start address, by adding incr.  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.

       --change-section-address sectionpattern{=,+,-}val
       --adjust-section-vma sectionpattern{=,+,-}val
           Set or change both the VMA address and the LMA address of any
           section matching sectionpattern.  If = is used, the section address
           is set to val.  Otherwise, val is added to or subtracted from the
           section address.  See the comments under --change-addresses, above.
           If sectionpattern does not match any sections in the input file, a
           warning will be issued, unless --no-change-warnings is used.

       --change-section-lma sectionpattern{=,+,-}val
           Set or change the LMA address of any sections matching
           sectionpattern.  The LMA address is the address where the section
           will be loaded into memory at program load time.  Normally this is
           the same as the VMA address, which is the address of the section at
           program run time, but on some systems, especially those where a
           program is held in ROM, the two can be different.  If = is used,
           the section address is set to val.  Otherwise, val is added to or
           subtracted from the section address.  See the comments under
           --change-addresses, above.  If sectionpattern does not match any
           sections in the input file, a warning will be issued, unless
           --no-change-warnings is used.

       --change-section-vma sectionpattern{=,+,-}val
           Set or change the VMA address of any section matching
           sectionpattern.  The VMA address is the address where the section
           will be located once the program has started executing.  Normally
           this is the same as the LMA address, which is the address where the
           section will be loaded into memory, but on some systems, especially
           those where a program is held in ROM, the two can be different.  If
           = is used, the section address is set to val.  Otherwise, val is
           added to or subtracted from the section address.  See the comments
           under --change-addresses, above.  If sectionpattern does not match
           any sections in the input file, a warning will be issued, unless
           --no-change-warnings is used.

       --change-warnings
       --adjust-warnings
           If --change-section-address or --change-section-lma or
           --change-section-vma is used, and the section pattern does not
           match any sections, issue a warning.  This is the default.

       --no-change-warnings
       --no-adjust-warnings
           Do not issue a warning if --change-section-address or
           --adjust-section-lma or --adjust-section-vma is used, even if the
           section pattern does not match any sections.

       --set-section-flags sectionpattern=flags
           Set the flags for any sections matching sectionpattern.  The flags
           argument is a comma separated string of flag names.  The recognized
           names are alloc, contents, load, noload, readonly, code, data, rom,
           share, and debug.  You can set the contents flag for a section
           which does not have contents, but it is not meaningful to clear the
           contents flag of a section which does have contents--just remove
           the section instead.  Not all flags are meaningful for all object
           file formats.

       --add-section sectionname=filename
           Add a new section named sectionname while copying the file.  The
           contents of the new section are taken from the file filename.  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.  Note - it may be necessary to use the --set-section-flags
           option to set the attributes of the newly created section.

       --dump-section sectionname=filename
           Place the contents of section named sectionname into the file
           filename, overwriting any contents that may have been there
           previously.  This option is the inverse of --add-section.  This
           option is similar to the --only-section option except that it does
           not create a formatted file, it just dumps the contents as raw
           binary data, without applying any relocations.  The option can be
           specified more than once.

       --rename-section oldname=newname[,flags]
           Rename a section from oldname to newname, optionally changing the
           section's flags to flags in the process.  This has the advantage
           over usng a linker script to perform the rename in that the output
           stays as an object file and does not become a linked executable.

           This option is particularly helpful when the input format is
           binary, since this will always create a section called .data.  If
           for example, you wanted instead to create a section called .rodata
           containing binary data you could use the following command line to
           achieve it:

                     objcopy -I binary -O <output_format> -B <architecture> \
                      --rename-section .data=.rodata,alloc,load,readonly,data,contents \
                      <input_binary_file> <output_object_file>

       --long-section-names {enable,disable,keep}
           Controls the handling of long section names when processing "COFF"
           and "PE-COFF" object formats.  The default behaviour, keep, is to
           preserve long section names if any are present in the input file.
           The enable and disable options forcibly enable or disable the use
           of long section names in the output object; when disable is in
           effect, any long section names in the input object will be
           truncated.  The enable option will only emit long section names if
           any are present in the inputs; this is mostly the same as keep, but
           it is left undefined whether the enable option might force the
           creation of an empty string table in the output file.

       --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 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.

       --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 --change-leading-char because it
           always changes the symbol name when appropriate, regardless of the
           object file format of the output file.

       --reverse-bytes=num
           Reverse the bytes in a section with output contents.  A section
           length must be evenly divisible by the value given in order for the
           swap to be able to take place. Reversing takes place before the
           interleaving is performed.

           This option is used typically in generating ROM images for
           problematic target systems.  For example, on some target boards,
           the 32-bit words fetched from 8-bit ROMs are re-assembled in
           little-endian byte order regardless of the CPU byte order.
           Depending on the programming model, the endianness of the ROM may
           need to be modified.

           Consider a simple file with a section containing the following
           eight bytes:  12345678.

           Using --reverse-bytes=2 for the above example, the bytes in the
           output file would be ordered 21436587.

           Using --reverse-bytes=4 for the above example, the bytes in the
           output file would be ordered 43218765.

           By using --reverse-bytes=2 for the above example, followed by
           --reverse-bytes=4 on the output file, the bytes in the second
           output file would be ordered 34127856.

       --srec-len=ival
           Meaningful only for srec output.  Set the maximum length of the
           Srecords being produced to ival.  This length covers both address,
           data and crc fields.

       --srec-forceS3
           Meaningful only for srec output.  Avoid generation of S1/S2
           records, creating S3-only record format.

       --redefine-sym old=new
           Change the name of a symbol old, to new.  This can be useful when
           one is trying link two things together for which you have no
           source, and there are name collisions.

       --redefine-syms=filename
           Apply --redefine-sym to each symbol pair "old new" listed in the
           file filename.  filename is simply a flat file, with one symbol
           pair per line.  Line comments may be introduced by the hash
           character.  This option may be given more than once.

       --weaken
           Change all global symbols in the file to be weak.  This can be
           useful when building an object which will be linked against other
           objects using the -R option to the linker.  This option is only
           effective when using an object file format which supports weak
           symbols.

       --keep-symbols=filename
           Apply --keep-symbol option to each symbol listed in the file
           filename.  filename is simply a flat file, with one symbol name per
           line.  Line comments may be introduced by the hash character.  This
           option may be given more than once.

       --strip-symbols=filename
           Apply --strip-symbol option to each symbol listed in the file
           filename.  filename is simply a flat file, with one symbol name per
           line.  Line comments may be introduced by the hash character.  This
           option may be given more than once.

       --strip-unneeded-symbols=filename
           Apply --strip-unneeded-symbol option to each symbol listed in the
           file filename.  filename is simply a flat file, with one symbol
           name per line.  Line comments may be introduced by the hash
           character.  This option may be given more than once.

       --keep-global-symbols=filename
           Apply --keep-global-symbol option to each symbol listed in the file
           filename.  filename is simply a flat file, with one symbol name per
           line.  Line comments may be introduced by the hash character.  This
           option may be given more than once.

       --localize-symbols=filename
           Apply --localize-symbol option to each symbol listed in the file
           filename.  filename is simply a flat file, with one symbol name per
           line.  Line comments may be introduced by the hash character.  This
           option may be given more than once.

       --globalize-symbols=filename
           Apply --globalize-symbol option to each symbol listed in the file
           filename.  filename is simply a flat file, with one symbol name per
           line.  Line comments may be introduced by the hash character.  This
           option may be given more than once.

       --weaken-symbols=filename
           Apply --weaken-symbol option to each symbol listed in the file
           filename.  filename is simply a flat file, with one symbol name per
           line.  Line comments may be introduced by the hash character.  This
           option may be given more than once.

       --alt-machine-code=index
           If the output architecture has alternate machine codes, use the
           indexth 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 ELF based architectures if the index alternative
           does not exist then the value is treated as an absolute number to
           be stored in the e_machine field of the ELF header.

       --writable-text
           Mark the output text as writable.  This option isn't meaningful for
           all object file formats.

       --readonly-text
           Make the output text write protected.  This option isn't meaningful
           for all object file formats.

       --pure
           Mark the output file as demand paged.  This option isn't meaningful
           for all object file formats.

       --impure
           Mark the output file as impure.  This option isn't meaningful for
           all object file formats.

       --prefix-symbols=string
           Prefix all symbols in the output file with string.

       --prefix-sections=string
           Prefix all section names in the output file with string.

       --prefix-alloc-sections=string
           Prefix all the names of all allocated sections in the output file
           with string.

       --add-gnu-debuglink=path-to-file
           Creates a .gnu_debuglink section which contains a reference to
           path-to-file and adds it to the output file.

       --keep-file-symbols
           When stripping a file, perhaps with --strip-debug or
           --strip-unneeded, retain any symbols specifying source file names,
           which would otherwise get stripped.

       --only-keep-debug
           Strip a file, removing contents of any sections that would not be
           stripped by --strip-debug and leaving the debugging sections
           intact.  In ELF files, this preserves all note sections in the
           output.

           The intention is that this option will be used in conjunction with
           --add-gnu-debuglink to create a two part executable.  One a
           stripped binary which will occupy less space in RAM 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:

           1.<Link the executable as normal.  Assuming that is is called>
               "foo" then...

           1.<Run "objcopy --only-keep-debug foo foo.dbg" to>
               create a file containing the debugging info.

           1.<Run "objcopy --strip-debug foo" to create a>
               stripped executable.

           1.<Run "objcopy --add-gnu-debuglink=foo.dbg foo">
               to add a link to the debugging info into the stripped
               executable.

           Note---the choice of ".dbg" as an extension for the debug info file
           is arbitrary.  Also the "--only-keep-debug" step is optional.  You
           could instead do this:

           1.<Link the executable as normal.>
           1.<Copy "foo" to  "foo.full">
           1.<Run "objcopy --strip-debug foo">
           1.<Run "objcopy --add-gnu-debuglink=foo.full foo">

           i.e., the file pointed to by the --add-gnu-debuglink can be the
           full executable.  It does not have to be a file created by the
           --only-keep-debug switch.

           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.

       --strip-dwo
           Remove the contents of all DWARF .dwo sections, leaving the
           remaining debugging sections and all symbols intact.  This option
           is intended for use by the compiler as part of the -gsplit-dwarf
           option, which splits debug information between the .o file and a
           separate .dwo file.  The compiler generates all debug information
           in the same file, then uses the --extract-dwo option to copy the
           .dwo sections to the .dwo file, then the --strip-dwo option to
           remove those sections from the original .o file.

       --extract-dwo
           Extract the contents of all DWARF .dwo sections.  See the
           --strip-dwo option for more information.

       --file-alignment num
           Specify the file alignment.  Sections in the file will always begin
           at file offsets which are multiples of this number.  This defaults
           to 512.  [This option is specific to PE targets.]

       --heap reserve
       --heap reserve,commit
           Specify the number of bytes of memory to reserve (and optionally
           commit) to be used as heap for this program.  [This option is
           specific to PE targets.]

       --image-base value
           Use value as the base address of your program or dll.  This is the
           lowest memory location that will be used when your program or dll
           is loaded.  To reduce the need to relocate and improve performance
           of your dlls, each should have a unique base address and not
           overlap any other dlls.  The default is 0x400000 for executables,
           and 0x10000000 for dlls.  [This option is specific to PE targets.]

       --section-alignment num
           Sets the section alignment.  Sections in memory will always begin
           at addresses which are a multiple of this number.  Defaults to
           0x1000.  [This option is specific to PE targets.]

       --stack reserve
       --stack reserve,commit
           Specify the number of bytes of memory to reserve (and optionally
           commit) to be used as stack for this program.  [This option is
           specific to PE targets.]

       --subsystem which
       --subsystem which:major
       --subsystem which:major.minor
           Specifies the subsystem under which your program will execute.  The
           legal values for which are "native", "windows", "console", "posix",
           "efi-app", "efi-bsd", "efi-rtd", "sal-rtd", and "xbox".  You may
           optionally set the subsystem version also.  Numeric values are also
           accepted for which.  [This option is specific to PE targets.]

       --extract-symbol
           Keep the file's section flags and symbols but remove all section
           data.  Specifically, the option:

           *<removes the contents of all sections;>
           *<sets the size of every section to zero; and>
           *<sets the file's start address to zero.>

           This option is used to build a .sym file for a VxWorks kernel.  It
           can also be a useful way of reducing the size of a --just-symbols
           linker input file.

       --compress-debug-sections
           Compress DWARF debug sections using zlib.

       --decompress-debug-sections
           Decompress DWARF debug sections using zlib.

       -V
       --version
           Show the version number of objcopy.

       -v
       --verbose
           Verbose output: list all object files modified.  In the case of
           archives, objcopy -V lists all members of the archive.

       --help
           Show a summary of the options to objcopy.

       --info
           Display a list showing all architectures and object formats
           available.

       @file
           Read command-line options from file.  The options read are inserted
           in place of the original @file option.  If file does not exist, or
           cannot be read, then the option will be treated literally, and not
           removed.

           Options in file 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 file may itself contain additional
           @file options; any such options will be processed recursively.
