     This specifies the *size* of a pointer and its ``<abi>`` and
     ``<pref>``\erred alignments for address space ``n``. ``<pref>`` is optional
     and defaults to ``<abi>``. The fourth parameter ``<idx>`` is the size of the
     index that used for address calculation, which must be less than or equal
     to the pointer size. If not
     specified, the default index size is equal to the pointer size. All sizes
