| // { "vstorea_half", {3,1}, {E_ANY,EX_SIZET,E_ANY}}, |

| // <param rules> - list of rules used to derive all of the function formal |
| // argument types. EX_ prefixed are simple types, other derived from the |
| // latest 'lead' argument type in the order of encoding from first to last. |
| // E_ANY - use prev lead type, E_CONSTPTR_ANY - make const pointer out of |
| // prev lead type, etc. see ParamIterator::getNextParam() for details. |
