llvm dev - Nov 2015 - Revisions that cause buildbot problems but aren't on blame lists

Hi Galina,

The failing build was
http://lab.llvm.org:8011/builders/clang-cmake-mips/builds/10220 and the commit
that caused it was 'r251331 [compiler-rt] Fix ptrace interceptor for
aarch64'.

Hello Bill, Daniel,

Could you point me to the exact build and tell me the correct revision to blame,
please?

Most likely, this means that your bot defines wrong dependencies. I can look in
to this, once I'll learn the details.

Thanks

Galina

Hi,

I've had this problem on a compiler-rt change too. It was on the
clang-cmake-mips builder earlier this week.

Hi Bill,

This is a known issue, and maybe we should look into that, now that
the two other critical issues (silent master and ignoring exceptions)
are done. Another repository that has the same effect is Zorg (the bot
infrastructure).

Galina,

First, the easy one: I think we should include Zorg on *all* monitors.

The not so easy one: I believe this is just a matter of creating a
monitor based on the test-suite, and put all test-suite bots checking
on it too. But from what I remember, you can only create lists of
monitors, not necessarily collate them per bot. Is that true?

cheers,
--renato

Adhemerval,

Can you have a look?

I already have a fix for the problem, we just have some definitions in odd
places. I XFAIL'd it while I was in the US but I'll commit the fix
shortly.
