| The generic type name <type>gentype<replaceable>n</replaceable></type> |
| represents <replaceable>n</replaceable>-element vectors of <type>gentype</type> |
| elements. The suffix <replaceable>n</replaceable> is also used in the |
| function names (i.e. <function>vload<replaceable>n</replaceable></function>, |
| <function>vstore<replaceable>n</replaceable></function>, etc.), where |
| <replaceable>n</replaceable> = 2, 3, 4, 8, or 16. |
