[LLVMdev] The performance of LLVM vs GCC
Hi Martin, > Here's a more recent one: > > http://www.phoronix.com/scan.php?page=article&item=gcc_46_llvm29&num=1 a few comments: (1) The smallpt benchmark uses openmp which dragonegg supports but clang does not. That's why on the machines with N processors the clang compiled binary takes N times as long as the others: it is only using one processor unlike the others. (2) On the Himeno benchmark dragonegg beats the pants off everyone el...

[LLVMdev] The performance of LLVM vs GCC
...ng OpenMP or not, yes, I mentioned this in another email in this thread. I particularly enjoyed the use of -O0 :) They know about these issues since they added notes about -O0 and openmp to one of their previous sets of benchmarks, probably because of feedback. They never seemed to realize that smallpt uses openmp though! I notice that they do have a note about openmp after the graphicsmagick benchmark, and don't report results for himeno (they were using -O0 for this before), so I guess that's progress. Ciao, Duncan. and (in this case) are testing on a micro architecture that only o...

Hi all, This talk includes the performance comparison between LLVM and GCC (page 30/31): LLVM wins a lot for both compilation and execution time. http://llvm.org/pubs/2008-10-04-ACAT-LLVM-Intro.pdf That talk and data were in 2008, I was wondering if there is any updated performance evaluation between the latest LLVM and GCC?

[LLVMdev] [RFC] AArch64: Should we disable GlobalMerge?
Hi all, I've started looking at the GlobalMerge pass, enabled by default on ARM and AArch64. I think we should reconsider that, at least for AArch64. As is, the pass just merges all globals together, in groups of 4KB (AArch64, 128B on ARM). At the time it was enabled, the general thinking was "it's almost free, it doesn't affect performance much, we might as well use it".

[LLVMdev] Proposal: change LNT’s regression detection algorithm and how it is used to reduce false positives
tl;dr in low data situations we don’t look at past information, and that increases the false positive regression rate. We should look at the possibly incorrect recent past runs to fix that. Motivation: LNT’s current regression detection system has false positive rate that is too high to make it useful. With test suites as large as the llvm “test-suite” a single report will show hundreds of

How to get optimization remarks while testing with lnt in llvm
Hi, I'm new to llvm and am trying to run benchmarks from the test-suite using lnt to check loop-vectorization for various benchmarks. Test are compiling and executing fine, but I am not getting optimization remarks while using flags like -Rpass-missed=loop-vectorize and -Rpass-analysis=loop-vectorize I've tried running it like this: lnt runtest test-suite --sandbox SANDBOX --cc

[LLVMdev] Please benchmark new x86 vector shuffle lowering, planning to make it the default very soon!
Hi Chandler, Thanks for fixing the problem with the insertps mask. Generally the new shuffle lowering looks promising, however there are some cases where the codegen is now worse causing runtime performance regressions in some of our internal codebase. You have already mentioned how the new shuffle lowering is missing some features; for example, you explicitly said that we currently lack of

[LLVMdev] [3.6 Release] RC3 has been tagged
Hello testers, Start your engines, RC3 has just been tagged (at r229050 on the branch). If this one looks good, it will become the release. There has been quite a bit of activity on the branch since RC2; let's hope it's all goodness :-) Please let me know how it looks, and upload binaries to the sftp as usual. Thanks for all your efforts so far! - Hans
