Thanks for this new implementation, it's a lot cleaner than the previous one, especially the fallback to setcond if not implemented, and the argument alias for the x86 backend, deferring the issue to the register allocator instead of trying to do that in the backend. >From my side, I am ok with it. That said I'd also like to have at least the opinion of Malc and Blue (Cc:ed).
