@item --pad-to @var{address}
Pad the output file up to the virtual address @var{address}. This is
done by increasing the size of the last section. The extra space is
filled in with the value specified by @samp{--gap-fill} (default zero).
@item --set-start @var{val}
Set the address of the new file to @var{val}. Not all object file
