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.  *Note
