Detailed Description

template<>
struct sse::svec< 4, void * >

data representation and operations on a vector of 4 pointers. This is only used in gather and scatter.

including gather general/gather base offsets, scatter general, scatter base offsets

Here, we will define a special compile time dependent type for ptrs vector

Note

In 32bit platform, svec<4,void*> extends svec<4,uint32_t>, while in 64bit platform, svec<4,void*> extends svec<4,uint64_t>.
