Cool test :) It seems to work fine now, I don't see any new failures. IIUC, Kristof is also giving it another run.

...know of any further issues preventing us flipping the switch. At this point, I’d aim to flip the switch shortly after the creation of the 6.0.0 release branch, so that GlobalISel can harden a bit more enabled-by-default on trunk before it goes into an LLVM release (presumably 7.0.0 then).

...ow let all users of the release know to disable it by adding a convoluted command line option (‘-mllvm -global-isel=0’?) Combining the 2 observations above, I think it’s better to do the switch shortly after a release branch is taken, rather than just before it. I hope that makes sense?

...''s out of budget. So the only challenger of the intel board is the Foxconn one, which supports 16GB ram, instead of the 8GB of the Intel. (The ASUS one does this, too, but I tend to avoid it when selecting workstation/server-grade HW.) What do you suggest?

...ble, although the fact that LowLevelType doesn't support vectors of pointers is already actionable. Nevertheless, I thought to share what I see as is, to see if others see similar results so far. I thought Diana was going to look into fallback rate on the test-suite on AArch64 linux?

[RFC] Making -mcpu=generic the default for ARM armv7a and arm8a rather than -mcpu=cortex-a8 or -mcpu=cortex-a53
...aking those changes shortly. I think the comments also make clear that it's less obvious whether we'd want -mcpu=native to become a default. It's probably good for some use cases, but really not good for other use cases. I won't be making that change, nor advocate for it. Thanks!

Overall, my impression is that GlobalISel is ready to be enabled by default for AArch64 at -O0, if others also believe it's ready. Thanks, Kristof Detailed observations: 1.
