I suggest to change the member name in `StridedMemRefType`, if you see `data` member, it's hard to guess if it;'s aligned.  

```c++
template <typename T, int N>
struct StridedMemRefType {
  T *basePtr;
  T *data;
```

Maybe then I guess it's better to change them to  `allocatedPtr` and `alignedData`? If you think it's good, then I'll proceed it
