Well I have been trying to play around with LLVM on ARM Cortex-M4 micro controllers specifically the STM32F4 series of my controllers there is a github project that tries to use Clang.

Now if I had the time and experience I wanted to try and compile this library called py2llvm. The library that can compile static variables and python syntax into LLVM bitcode with C like performance. I think that is the best of both worlds.
