Portable Efficient Assembly Code-generation in High-level Python

PeachPy is a Python framework for writing high-performance assembly kernels.

PeachPy aims to simplify writing optimized assembly kernels while preserving all optimization opportunities of traditional assembly.

You can use the same code to generate assembly for Windows, Unix, and Golang assembly. The library handles the various ABIs automatically. I haven't seen this cool project before.

Among the cool features is the ability to invoke the generated assembly as regular Python functions. Nice.
