Re: tsan buildbot failure possibly due to DWARFv5 switch

2022-01-25 Thread David Spickett
That libl deadlock test has been flaky for us across many bots
recently, you just had bad timing there and there is a green build
later. (scudo resident memory size is another test like this). I'll
make sure these are investigated properly.

What I did see was a debug related profiling test failing
"Linux/instrprof-debug-info-correlate.c"
https://lab.llvm.org/buildbot/#/builders/176/builds/1325. This was
fixed by 
https://github.com/llvm/llvm-project/commit/38e16e1cebb891ad47b85727bf46f7dac6d7da94
and our 2 stage SVE bots are just lagging behind.

Otherwise we're all green on our bots. Thanks for following up and
we'll root out what's causing the flaky tests.

Thanks,
David Spickett.

Ah, great - thanks for the details & for looking into the flakiness to help
improve buildbot quality and confidence!
