Hi Paul, Yeah, the status matrix is very out of date. I would like to see it automatically updated by our regression tests / continuous integration tests. However, those are also wildly out of date.
It would be *fabulous* if someone had time / money / energy to revamp our testing infrastructure and get some of these things up to date. There was some work last summer in re-writing the regression tester that was never finished, Gabe has done some great work getting the unittests working again, and I know that internally AMD and ARM have tests that run. It's unfortunate that it's not a priority for me :/. This is what I feel most guilty about ;). @EVERYONE: If you know of anyone (junior grad students, masters students, motivated undergrads, anyone who wants to contribute to an open source project, etc.) who would be up for working on this, I'm happy to help advise! This isn't a *hard* project. It will just take some time and effort. This would have very significant impact on this project. I can't think of anything that would have a broader impact!
