Sorry for the radio silence, my gpg pinentry broke on my laptop and rather than fix it I took it as an opportunity to switch my laptop over to Qubes OS so I've been busy setting that up, still more to do but it is configured enough now for me to shift my focus back to work :)

godbolt doesn't have RISC-V targets on it but someone else has a compiler explorer with it, will add this to http:/​/​links.riscy.tv later: https:/​/​cx.rv8.io/​

So @github was acquired by @Microsoft and as a result I will be moving http:/​/​code.riscy.tv to @gitlab Unknown ETA: it's stuck importing my repos right now. I'll be using the free tier SaaS http:/​/​gitlab.com offers to avoid additional expenses right now #movingtogitlab

Check out the spiffy new logo @miblo_ has made for the series! I didn't even ask for a logo - he just can't help himself from doing top tier work!

It seems impossible to get the GCC RISC-V backend to generate jump tables for switch statements. Maybe it isn't implemented? https:/​/​godbolt.org/​g/​Q3z5bK
