Thanks for pointing that out. As the OpenRISC maintainer of Linux/GCC etc I didn't even know about this effort. Let alone the tool.

I wrote this article with openrisc examples but it is meant to be easy to transfer to other architectures. In the next article I will use both x86 and openrisc examples.
