I don't know if you are maintaining also clang-aarch64-sve-vla-2stage but it takes far too long right now (>10 hours).
Yes, I actually increased its ccache size on July 6th but only from 5 GB to 20 GB because the machine running that builder is also a development box. Looking at the build times graph it looks like it helped a bit but not a lot.
I now increased the size again to 40 GB. I'll monitor to see if there's an impact.
It notifies for large number of people which is overly noisy right now. See: https://lab.llvm.org/buildbot/#/builders/198/builds/1234
Does adding a “depends_on_projects” argument help reduce the number of notified people? Or is there something else that could/should be done about that?
One thing I noticed is that it seems to be missing the `depends_on_projects` for the buildbot configuration: that means it'll include commits that touches part of the codebase totally unrelated to what it is testing (like flang and mlir). That would be a first easy step to reduce the number of unrelated changes that get flagged incorrectly.
Thank you for the suggestion, I see that many builders running on Linaro workers don't have it. I'll prepare a patch to add “depends_on_projects” arguments to them.
Though specifically for clang-aarch64-sve-vla-2stage IIUC its value would be ["llvm", "mlir", "clang", "flang"] (since it's meant to test flang as well), so perhaps it wouldn't change much in practice?
