 3 Linker Scripts
 ****************
 
 Every link is controlled by a "linker script".  This script is written
 in the linker command language.
 
    The main purpose of the linker script is to describe how the
 sections in the input files should be mapped into the output file, and
 to control the memory layout of the output file.  Most linker scripts
 do nothing more than this.  However, when necessary, the linker script
 can also direct the linker to perform many other operations, using the
 commands described below.
 
    The linker always uses a linker script.  If you do not supply one
 yourself, the linker will use a default script that is compiled into the
 linker executable.  You can use the `--verbose' command line option to
 display the default linker script.  Certain command line options, such
 as `-r' or `-N', will affect the default linker script.
 
    You may supply your own linker script by using the `-T' command line
 option.  When you do this, your linker script will replace the default
 linker script.
 
    You may also use linker scripts implicitly by naming them as input
 files to the linker, as though they were files to be linked.
