This is an LLVM IR generator for eBPF programs in Python. We use llvmlite to generate LLVM IR code from pure Python code. This is then compiled to LLVM object files, which can be loaded into the kernel for execution.

Development

Step 0. Make a virtual environment and activate it using python3 -m venv .venv && source .venv/bin/activate.
Step 1. Run make install to install the required dependencies.
Step 2. Run make to see the compilation output of the example.
Step 3. Run check.sh to check if generated object file passes through the verifier inside the examples directory.
Step 4. Run make in the examples/c-form directory to modify the example C BPF program to check the actual LLVM IR generated by clang.

Development Notes

Run ./check.sh run execve2.o; in examples folder
