[llvm-dev] clang-ppc64be-linux-lnt flakiness
Hi Bill, just a heads up but this bot seems to have spuriously failed on a build that only pulled in my commit r272505 which is unrelated. http://lab.llvm.org:8011/builders/clang-ppc64be-linux-lnt/builds/4883 -- Sean Silva -------------- next part -------------- An HTML attachment was scrubbed...

[llvm-dev] clang-ppc64be-linux-lnt flakiness
Also, `Clang Tools :: include-fixer/merge.test` seems to be a bit flaky: http://lab.llvm.org:8011/builders/clang-ppc64le-linux-multistage/builds/1304 http://lab.llvm.org:8011/builders/clang-ppc64le-linux-multistage/builds/1315 Ben, it looks like you're the one that added that test. Is there any chance it could be a nondeterminism or something in the code? -- Sean Silva On Sun, Jun 12, 2016 at 1:41 AM, Sean Silva <chisophugis at gmail.com> wrote:> Hi Bill, just a heads up but this bot seems to have spuriously failed on a > build that only pulled in my commit r272505 which is unrelated. > > http://lab.llvm.org:8011/builders/clang-ppc64be-linux-lnt/builds/4883 > > -- Sean Silva >-------------- next part -------------- An HTML attachment was scrubbed...

I threw all the sanitizers I had access to on this test and didn't find anything. The merging uses threads so I can't rule out nondeterminism. It's strange that it only happens on ppc64le and only on stage 2, so an actual miscompile wouldn't surprise me either.
