Just a follow-up. I got rid of llvm on my Gentoo nvidia machine and so far see no ill effects. Granted, I'm using an i7 980 Extreme, 24GB with an nvidia 960-based card, so it's pretty good hardware but I've seen no ill effects so far. Additionally, with Google releasing Google Earth as a web app at least inside of Chrome it runs fine. Pan/zoom/tilt 3D views of the world. Lots of fun and if it was faster with llvm I don't think I'd notice it. As for my wife's laptop which started this discussion I had an emerge 2 weeks ago of about 200 packages, mostly KDE, which took almost 24 hours to build on a 5-6 year old laptop.This time around I have about 175 packages today. We'll see how long it takes as a data point but I've decided to move her to Ubuntu. I think I need to be spending my time more productively than building this much code this often. I already run Ubuntu as a VM on my Gentoo machine due to apps not supported (or not building correctly) by Gentoo in portage. Sad as it will be the first non-Gentoo boot in my house in about 15 years.
