------------------------------------
Hi [~andrew.wang],
Good catch on this. It's good to make XOR codec work and we'll check to see if
any gap exists. Will also resume the work here and update the patch. Thanks!

> Raw XOR coder is utilized in Reed-Solomon erasure coder in an optimization to
> recover only one erased block which is in most often case. It can also be
> used in HitchHiker coder. Therefore a native implementation of it would be
> deserved for performance gain.
