| .SH "DESCRIPTION" |
| .IX Header "DESCRIPTION" |
| The \s-1GNU\s0 \f(CW\*(C`objcopy\*(C'\fR utility copies the contents of an object |
| file to another. \f(CW\*(C`objcopy\*(C'\fR uses the \s-1GNU\s0 \s-1BFD\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 \f(CW\*(C`objcopy\*(C'\fR is controlled by command-line options. |
| Note that \f(CW\*(C`objcopy\*(C'\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 |
| \&\f(CW\*(C`objcopy\*(C'\fR creates temporary files to do its translations and |
| deletes them afterward. \f(CW\*(C`objcopy\*(C'\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 |
| \&\f(CW\*(C`objcopy\*(C'\fR can be used to generate S-records by using an output |
| target of \fBsrec\fR (e.g., use \fB\-O srec\fR). |
| .PP |
| \&\f(CW\*(C`objcopy\*(C'\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 |
| \&\f(CW\*(C`objcopy\*(C'\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 \- \f(CW\*(C`objcopy\*(C'\fR is not able to change the endianness of its input |
| files. If the input format has an endianness, (some formats do not), |
| \&\f(CW\*(C`objcopy\*(C'\fR can only copy the inputs into file formats that have the |
| same endianness or which have no endianness (eg \fBsrec\fR). |

| .IX Item "outfile" |
| The input and output files, respectively. |
| If you do not specify \fIoutfile\fR, \f(CW\*(C`objcopy\*(C'\fR creates a |
| temporary file and destructively renames the result with |
| the name of \fIinfile\fR. |

| .IX Item "-F bfdname" |
| .Ip "\f(CW\*(C`\-\-target=\f(CIbfdname\f(CW\*(C'\fR" 4 |
| .IX Item "--target=bfdname" |
| Use \fIbfdname\fR as the object format for both the input and the output |
| file; i.e., simply transfer data from source to destination with no |
| translation. |
| .Ip "\f(CW\*(C`\-B \f(CIbfdarch\f(CW\*(C'\fR" 4 |
| .IX Item "-B bfdarch" |
| .Ip "\f(CW\*(C`\-\-binary\-architecture=\f(CIbfdarch\f(CW\*(C'\fR" 4 |
| .IX Item "--binary-architecture=bfdarch" |
| Useful when transforming a raw binary 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. |

| .IX Item "-j sectionname" |
| .Ip "\f(CW\*(C`\-\-only\-section=\f(CIsectionname\f(CW\*(C'\fR" 4 |
| .IX Item "--only-section=sectionname" |
| Copy only the named section from the input file to the output file. |
| This option may be given more than once. Note that using this option |

| Do not copy compiler-generated local symbols. |
| (These usually start with \fBL\fR or \fB.\fR.) |
| .Ip "\f(CW\*(C`\-b \f(CIbyte\f(CW\*(C'\fR" 4 |
| .IX Item "-b byte" |
| .Ip "\f(CW\*(C`\-\-byte=\f(CIbyte\f(CW\*(C'\fR" 4 |
| .IX Item "--byte=byte" |
| Keep only every \fIbyte\fRth byte of the input file (header data is not |
| affected). \fIbyte\fR can be in the range from 0 to \fIinterleave\fR\-1, |
| where \fIinterleave\fR is given by the \fB\-i\fR or \fB\*(--interleave\fR |
| option, or the default of 4. This option is useful for creating files |
| to program \s-1ROM\s0. It is typically used with an \f(CW\*(C`srec\*(C'\fR output |
| target. |
| .Ip "\f(CW\*(C`\-i \f(CIinterleave\f(CW\*(C'\fR" 4 |
| .IX Item "-i interleave" |
| .Ip "\f(CW\*(C`\-\-interleave=\f(CIinterleave\f(CW\*(C'\fR" 4 |
| .IX Item "--interleave=interleave" |
| Only copy one out of every \fIinterleave\fR bytes. Select which byte to |
| copy with the \fI\-b\fR or \fB\*(--byte\fR option. The default is 4. |
| \&\f(CW\*(C`objcopy\*(C'\fR ignores this option if you do not specify either \fB\-b\fR or |
| \&\fB\*(--byte\fR. |
| .Ip "\f(CW\*(C`\-p\*(C'\fR" 4 |
| .IX Item "-p" |
| .Ip "\f(CW\*(C`\-\-preserve\-dates\*(C'\fR" 4 |
| .IX Item "--preserve-dates" |
| Set the access and modification dates of the output file to be the same |
| as those of the input file. |
| .Ip "\f(CW\*(C`\-\-debugging\*(C'\fR" 4 |
| .IX Item "--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. |
| .Ip "\f(CW\*(C`\-\-gap\-fill \f(CIval\f(CW\*(C'\fR" 4 |
| .IX Item "--gap-fill val" |
| Fill gaps between sections with \fIval\fR. This operation applies to |
| the \fIload address\fR (\s-1LMA\s0) 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\fR. |
| .Ip "\f(CW\*(C`\-\-pad\-to \f(CIaddress\f(CW\*(C'\fR" 4 |
| .IX Item "--pad-to address" |
| Pad the output file up to the load address \fIaddress\fR. 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\fR (default zero). |
| .Ip "\f(CW\*(C`\-\-set\-start \f(CIval\f(CW\*(C'\fR" 4 |
| .IX Item "--set-start val" |
| Set the start address of the new file to \fIval\fR. Not all object file |
| formats support setting the start address. |
| .Ip "\f(CW\*(C`\-\-change\-start \f(CIincr\f(CW\*(C'\fR" 4 |
| .IX Item "--change-start incr" |
| .Ip "\f(CW\*(C`\-\-adjust\-start \f(CIincr\f(CW\*(C'\fR" 4 |
| .IX Item "--adjust-start incr" |
| Change the start address by adding \fIincr\fR. Not all object file |
| formats support setting the start address. |
| .Ip "\f(CW\*(C`\-\-change\-addresses \f(CIincr\f(CW\*(C'\fR" 4 |
| .IX Item "--change-addresses incr" |
| .Ip "\f(CW\*(C`\-\-adjust\-vma \f(CIincr\f(CW\*(C'\fR" 4 |
| .IX Item "--adjust-vma incr" |
| Change the \s-1VMA\s0 and \s-1LMA\s0 addresses of all sections, as well as the start |
| address, by adding \fIincr\fR. 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. |
| .Ip "\f(CW\*(C`\-\-change\-section\-address \f(CIsection\f(CW{=,+,\-}\f(CIval\f(CW\*(C'\fR" 4 |

| .IX Item "--adjust-section-vma section{=,+,-}val" |
| Set or change both the \s-1VMA\s0 address and the \s-1LMA\s0 address of the named |
| \&\fIsection\fR. If \fB=\fR is used, the section address is set to |
| \&\fIval\fR. Otherwise, \fIval\fR is added to or subtracted from the |
| section address. See the comments under \fB\*(--change-addresses\fR, |
| above. If \fIsection\fR does not exist in the input file, a warning will |
| be issued, unless \fB\*(--no-change-warnings\fR is used. |
| .Ip "\f(CW\*(C`\-\-change\-section\-lma \f(CIsection\f(CW{=,+,\-}\f(CIval\f(CW\*(C'\fR" 4 |
| .IX Item "--change-section-lma section{=,+,-}val" |
| Set or change the \s-1LMA\s0 address of the named \fIsection\fR. The \s-1LMA\s0 |
| address is the address where the section will be loaded into memory at |
| program load time. Normally this is the same as the \s-1VMA\s0 address, which |
| is the address of the section at program run time, but on some systems, |
| especially those where a program is held in \s-1ROM\s0, the two can be |
| different. If \fB=\fR is used, the section address is set to |
| \&\fIval\fR. Otherwise, \fIval\fR is added to or subtracted from the |
| section address. See the comments under \fB\*(--change-addresses\fR, |
| above. If \fIsection\fR does not exist in the input file, a warning |
| will be issued, unless \fB\*(--no-change-warnings\fR is used. |
| .Ip "\f(CW\*(C`\-\-change\-section\-vma \f(CIsection\f(CW{=,+,\-}\f(CIval\f(CW\*(C'\fR" 4 |
| .IX Item "--change-section-vma section{=,+,-}val" |
| Set or change the \s-1VMA\s0 address of the named \fIsection\fR. The \s-1VMA\s0 |
| address is the address where the section will be located once the |
| program has started executing. Normally this is the same as the \s-1LMA\s0 |
| 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 |
| \&\s-1ROM\s0, the two can be different. If \fB=\fR is used, the section address |
| is set to \fIval\fR. Otherwise, \fIval\fR is added to or subtracted |
| from the section address. See the comments under |
| \&\fB\*(--change-addresses\fR, above. If \fIsection\fR does not exist in |
| the input file, a warning will be issued, unless |
| \&\fB\*(--no-change-warnings\fR is used. |
| .Ip "\f(CW\*(C`\-\-change\-warnings\*(C'\fR" 4 |
| .IX Item "--change-warnings" |
| .Ip "\f(CW\*(C`\-\-adjust\-warnings\*(C'\fR" 4 |
| .IX Item "--adjust-warnings" |
| If \fB\*(--change-section-address\fR or \fB\*(--change-section-lma\fR or |
| \&\fB\*(--change-section-vma\fR is used, and the named section does not |
| exist, issue a warning. This is the default. |
| .Ip "\f(CW\*(C`\-\-no\-change\-warnings\*(C'\fR" 4 |
| .IX Item "--no-change-warnings" |
| .Ip "\f(CW\*(C`\-\-no\-adjust\-warnings\*(C'\fR" 4 |
| .IX Item "--no-adjust-warnings" |
| Do not issue a warning if \fB\*(--change-section-address\fR or |
| \&\fB\*(--adjust-section-lma\fR or \fB\*(--adjust-section-vma\fR is used, even |
| if the named section does not exist. |
| .Ip "\f(CW\*(C`\-\-set\-section\-flags \f(CIsection\f(CW=\f(CIflags\f(CW\*(C'\fR" 4 |
| .IX Item "--set-section-flags section=flags" |
| Set the flags for the named section. The \fIflags\fR argument is a |
| comma separated string of flag names. The recognized names are |
| \&\fBalloc\fR, \fBcontents\fR, \fBload\fR, \fBnoload\fR, |
| \&\fBreadonly\fR, \fBcode\fR, \fBdata\fR, \fBrom\fR, \fBshare\fR, and |
| \&\fBdebug\fR. You can set the \fBcontents\fR flag for a section which |
| does not have contents, but it is not meaningful to clear the |
| \&\fBcontents\fR flag of a section which does have contents\*(--just remove |
| the section instead. Not all flags are meaningful for all object file |
| formats. |
| .Ip "\f(CW\*(C`\-\-add\-section \f(CIsectionname\f(CW=\f(CIfilename\f(CW\*(C'\fR" 4 |
| .IX Item "--add-section sectionname=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. |
| .Ip "\f(CW\*(C`\-\-change\-leading\-char\*(C'\fR" 4 |
| .IX Item "--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 \f(CW\*(C`objcopy\*(C'\fR 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. |
| .Ip "\f(CW\*(C`\-\-remove\-leading\-char\*(C'\fR" 4 |
| .IX Item "--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 |
| \&\f(CW\*(C`\-\-change\-leading\-char\*(C'\fR because it always changes the symbol name |
| when appropriate, regardless of the object file format of the output |
| file. |
| .Ip "\f(CW\*(C`\-\-srec\-len=\f(CIival\f(CW\*(C'\fR" 4 |
| .IX Item "--srec-len=ival" |
| Meaningful only for srec output. Set the maximum length of the Srecords |
| being produced to \fIival\fR. This length covers both address, data and |
| crc fields. |
| .Ip "\f(CW\*(C`\-\-srec\-forceS3\*(C'\fR" 4 |
| .IX Item "--srec-forceS3" |
| Meaningful only for srec output. Avoid generation of S1/S2 records, |
| creating S3\-only record format. |
| .Ip "\f(CW\*(C`\-\-redefine\-sym \f(CIold\f(CW=\f(CInew\f(CW\*(C'\fR" 4 |
| .IX Item "--redefine-sym old=new" |
| Change the name of a symbol \fIold\fR, to \fInew\fR. This can be useful |
| when one is trying link two things together for which you have no |
| source, and there are name collisions. |
| .Ip "\f(CW\*(C`\-\-weaken\*(C'\fR" 4 |
| .IX Item "--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 \f(CW\*(C`\-R\*(C'\fR option to the linker. This option is only effective when |
| using an object file format which supports weak symbols. |
| .Ip "\f(CW\*(C`\-\-keep\-symbols=\f(CIfilename\f(CW\*(C'\fR" 4 |
| .IX Item "--keep-symbols=filename" |
| Apply \fB\*(--keep-symbol\fR option to each symbol listed in the file |
| \&\fIfilename\fR. \fIfilename\fR 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. |
| .Ip "\f(CW\*(C`\-\-strip\-symbols=\f(CIfilename\f(CW\*(C'\fR" 4 |
| .IX Item "--strip-symbols=filename" |
| Apply \fB\*(--strip-symbol\fR option to each symbol listed in the file |
| \&\fIfilename\fR. \fIfilename\fR 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. |
| .Ip "\f(CW\*(C`\-\-keep\-global\-symbols=\f(CIfilename\f(CW\*(C'\fR" 4 |
| .IX Item "--keep-global-symbols=filename" |
| Apply \fB\*(--keep-global-symbol\fR option to each symbol listed in the |
| file \fIfilename\fR. \fIfilename\fR 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. |
| .Ip "\f(CW\*(C`\-\-localize\-symbols=\f(CIfilename\f(CW\*(C'\fR" 4 |
| .IX Item "--localize-symbols=filename" |
| Apply \fB\*(--localize-symbol\fR option to each symbol listed in the file |
| \&\fIfilename\fR. \fIfilename\fR 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. |
| .Ip "\f(CW\*(C`\-\-weaken\-symbols=\f(CIfilename\f(CW\*(C'\fR" 4 |
| .IX Item "--weaken-symbols=filename" |
| Apply \fB\*(--weaken-symbol\fR option to each symbol listed in the file |
| \&\fIfilename\fR. \fIfilename\fR 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. |
| .Ip "\f(CW\*(C`\-V\*(C'\fR" 4 |
| .IX Item "-V" |
| .Ip "\f(CW\*(C`\-\-version\*(C'\fR" 4 |
| .IX Item "--version" |
| Show the version number of \f(CW\*(C`objcopy\*(C'\fR. |

| .IX Item "-v" |
| .Ip "\f(CW\*(C`\-\-verbose\*(C'\fR" 4 |
| .IX Item "--verbose" |
| Verbose output: list all object files modified. In the case of |
| archives, \fBobjcopy \-V\fR lists all members of the archive. |
| .Ip "\f(CW\*(C`\-\-help\*(C'\fR" 4 |
