A Python library for parsing and analyzing existing LLVM IR.

The llvmlite project provides a lightweight LLVM API for Python, which includes a simple Python binding for writing the LLVM IR builder and JIT compiler. However, they do not provide a way to transform existing LLVM IR code to Python data structures.

Our project does not aim to provide a way to generate LLVM IR code, but to analyze existing LLVM IR code. Our project bases on the llvmlite project, mainly its binding and ffi module.

• The instruction supports match method to match the instruction with a pattern.
• Some built-in analysis.
• Same to llvmlite, Most of llvmlite uses the LLVM C API which is small but very stable (low maintenance when changing LLVM version).

llvmlite require at least Python 3.12 and is likely to work with greater versions.

Currently, we build LLVM bindings only for 14.x.x.

Make sure you have the LLVM development libraries installed. On MacOS, you can install them with:

$ brew install llvm

After

$ export LLVM_CONFIG=/usr/local/opt/llvm/bin/llvm-config

Then install the package in development mode:

$ make install

We use unittest for testing. You can run the tests with:

$ make test
