Let’s Write an LLVM Specializer for Python
“We’re going to build a single module Numba-like compiler for Python. It won’t be nearly as featureful or complete, but should demonstrate how you can go about building your own little LLVM specializer for a subset of Python or your own custom DSL expression compiler; and integrating it with the standard NumPy/SciPy stack for whatever scientific computing domain you work.”
