We don't expect everyone to test every single variant as one wouldn't be able to make forward progress. 1. Cross testing armv7-a / Thumb2 on qemu is acceptable. 2. If you have the resources (now with A15's) bootstrapping and regression testing on a modern machine would be so much better. 3. Cross test on qemu for older variants that may fail- you could consider cross testing on just the older variants. Testing on qemu comes with it's pitfalls, the threaded tests are a joke / the asan tests continue to randomly fail but in general it gives you a good enough indication about how badly things maybe broken. 4. Watch out for any regressions / bug reports from folks on bugzilla / the mailing lists and deal with any fallout that comes promptly. Thanks, Ramana > > -Y
