[llvm-dev] PSA: debuginfo-tests workflow changing slightly

Adrian, Mike, Chris? Any update on this? I've temporarily switched to
working on something different, but I plan to be back on this in a couple
of weeks. It's been a month since my first revert of this CL, which seems
like a reasonable amount of lead-time to deal with issues surrounding
downstream buildbot failures. I'm planning to move forward with this in a
couple of weeks once I finish up my current task, and I would really prefer
to not be further blocked by downstream buildbot failures.
Is there any way you can try Don's patch above on one of the failing
machines? Or proceed with your earlier solution of fixing up all the
jenkins builders?
