No worries - I knew that I'd have to do this at some point, even though I hadn't planned to do that today... I should have all of them green before end of today. I found that I actually can build LLVM 3.9 directly, as clang-6 can still build it directly (wheras the oldest gcc still installed can't build it directly). So it's a bit less painful than I thought at first The 3.9 instances (phycodurus, dragonet) tests are running right now, and I'm fairly sure they'll pass (most of a --noreport --nostatus run passed). Going forward building LLVM 4,5,6 now - the later versions take longer... Greetings, Andres Freund
