If we plant to support more languages than Python, it might be better to
use C++ (sorry).
But it does not mean that LLVM cannot be used. Either one can generate C
or C++, or just use the assembly language (which is very simple and
readable too: http://llvm.org/docs/LangRef.html).
We have exact knowledge about an ndarray at runtime:
- whether the array is contiguous or not
This can be JIT-compiled into specialized looping code by LLVM. These
kernels can then be stored in a database and resued.
If it matters, LLVM is embeddable in C++.
