Hi Alexis. It's very cool, MIPS is certainly one of the missing ports. In fact, it's less than that. Most of the rpython/jit directory does not have to be modified. It's 'just' rpython/jit/backend/mips and some support code in rpython/jit/backend/llsupport and that's it. The good starting point would be to add an empty MIPS backend and try running test_runner.py (like in backend/x86/test/test_runner.py or ARM). Are you familiar with ARM or x86 assembler? That would be a very good starting point to see how the current backends are implemented. Feel free to pop in on #pypy on irc.freenode.net, we're very irc-based. Is the part of the plan to contribute the MIPS backend to the pypy repo?
