%description
A lightweight LLVM python binding for writing JIT compilers

The old llvmpy  binding exposes a lot of LLVM APIs but the mapping of
C++-style memory management to Python is error prone. Numba_ and many JIT
compilers do not need a full LLVM API.  Only the IR builder, optimizer,
and JIT compiler APIs are necessary.

llvmlite is a project originally tailored for Numba's needs, using the
following approach:

* A small C wrapper around the parts of the LLVM C++ API we need that are
  not already exposed by the LLVM C API.
* A ctypes Python wrapper around the C API.
* A pure Python implementation of the subset of the LLVM IR builder that we
  need for Numba.
