- Pydrofoil is a multi-stage compiler that generates instruction set simulators (ISSs) from processor instruction set architectures (ISAs) specified in Sail.
- It achieves a >230x speedup over the C-based ISS generated by Sail on benchmarks.
- Pydrofoil combines an ahead-of-time (AOT) compiler with a tracing just-in-time (JIT) compiler built on the PyPy framework.
- It employs domain-specific optimizations tailored for ISS workloads, which are dominated by bit manipulation operations.
- The hybrid approach of AOT and JIT compilation provides greater performance gains than using either alone.
