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.

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. -.Sp -This option is particularly helpful when the input format is binary, -since this will always create a section called .data.

The most common such character is underscore, which compilers -often add before every symbol. This option tells \fBobjcopy\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 "\fB\-\-remove\-leading\-char\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 -\&\fB\-\-change\-leading\-char\fR because it always changes the symbol name -when appropriate, regardless of the object file format of the output -file. -.IP "\fB\-\-srec\-len=\fR\fIival\fR" 4 -.IX Item "--srec-len=ival" -Meaningful only for srec output.

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 \s-1ELF\s0 based architectures if the \fIindex\fR -alternative does not exist then the value is treated as an absolute -number to be stored in the e_machine field of the \s-1ELF\s0 header. -.IP "\fB\-\-writable\-text\fR" 4 -.IX Item "--writable-text" -Mark the output text as writable.
