The run page problem were triggered by one of my commits (sorry) and should be mitigated now, see the thread at http://lists.llvm.org/pipermail/llvm-dev/2017-July/115971.html <http://lists.llvm.org/pipermail/llvm-dev/2017-July/115971.html> I don't know about the submission problems, could they just an occasional network problem or are they a common phenomenon?

The debug info statistics bot is triggered by this job: http://green.lab.llvm.org/green/job/clang-stage2-Rthinlto/ which unfortunately hasn't been green in a very long time (>1mo).

Hi llvm-dev@ LNT produces statistics and graphs (such as [0]) of debuginfo metrics, such as number of source variables with locations. It looks like these haven't run [1] since the move from svn to git -- are there any plans to get these running again? I find it highly useful to identify what commits have affected variable locations and how significant an affect. [0]

Hi, I have been following the development of the /zorg/trunk/lnt project for a while and am wondering if there is some regular LLVM performance testing using LNT that can be accessed online? Are there any plans to create an officially used web service for this like e.g the llvm buildbots? Thanks a lot Tobi

Hi, I am currently investigating how to ensure that LNT only shows relevant performance regressions for the -O3 performance tests I am running. One question that came up here is why the default aggregate function for LNT is 'min' instead of 'mean'. This looks a little surprising from the statistical point, but also from looking at my test results picking 'min' seems

Is O3-vectorize redundant now that the loop vectorizer is enabled by default?

Right - you usually won't see a normal distribution in the noise of test results. You'll see results clustered around the lower bound with a long tail of slower and slower results. Depending on how many samples you do it might be appropriate to take the mean of the best 3, for example - but the general approach of taking the fastest N does have some basis in any case. Not necessarily the

Hi, I've lately been wondering where benchmarks for LLVM-generated binaries are hosted, and whether they're tracked over time. I'm asking because I'm thinking of where to put some benchmarks I've written using the open source Google benchmarking library [0] to test certain costs of XRay-instrumented binaries, the XRay runtime, and other related measurements (effect of
