My interest is just to get involved somehow in the NCG. Starting a new backend seemed reasonable only because I couldn't break something that didn't exist. ;-)

Well a big +1 from me for armv7 NCG.

I've been thinking about doing an ARM NCG, mainly for fun and to learn ARM. But in reality I'm not likely to get around to this any time soon. To give you an idea of the work involved, it took me around a week of hacking to do the x86_64 NCG, and that was largely based on the existing x86 one. Rather than wading into an ARM NCG directly, it would pay off to first refactor the existing NCG infrastructure to make it much easier to add new targets, as Carter mentioned. We should have machine descriptions rather than the existing way that involves writing lots of special-purpose code for each target. Cheers, Simon
