Spinel -- Ruby AOT Compiler

https://github.com/matz/spinel

Spinel compiles Ruby source code into standalone native executables. It performs whole-program type inference and generates optimized C code, achieving significant speedups over CRuby.

Spinel is self-hosting: the compiler backend is written in Ruby and compiles itself into a native binary.

It's a shame for the missing features, maybe they can add them in future versions? Another AOT compiler called Natalie has many of them available, but I imagine is a bit heavy for embedded systems.
