It reduces disruption for everyone who needs their builds to keep working, while allowing the failures to be investigated without the pressure of knowing that head is currently broken. That this patch has been hard to land is in the nature of the change itself.

I'm caught quite off-guard that it seems the LLVM buildbots don't cover our Windows support that well. It would also be great to know how we can improve the process to update dependency versions. The current way does not really encourage me to propose LLVM wide updates again.

>> Now that they are updated it turned out that one of the two last updated bots has an issue with this patch and that has been fixed. But now it seems to break Chromium. I don't have access to Windows so I don't know how I can test patches.

Thanks!

Would it make sense to put all these patches in one new review and then test that on Chromium and ask @glandium to test that too. Then we know whether it solves the issues. Do you want me to make a patch or do you want to do it?
