the input sections which map into it. You can override this by using
the section type. For example, in the script sample below, the
@samp{ROM} section is addressed at memory location @samp{0} and does not
need to be loaded when the program is run. The contents of the
@samp{ROM} section will appear in the linker output file as usual.
