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
- 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.
