Hi Folks, Looks like our LNT ARM buildbot with the vectorizer is running and producing good results. There are only 11 failures: FAIL: MultiSource/Applications/Burg/burg.execution_time (1 of 1104) FAIL: MultiSource/Applications/ClamAV/clamscan.execution_time (2 of 1104) FAIL: MultiSource/Applications/lemon/lemon.execution_time (3 of 1104) FAIL: MultiSource/Applications/sqlite3/sqlite3.execution_time (4 of 1104) FAIL: MultiSource/Benchmarks/McCat/12-IOtest/iotest.execution_time (...

...could see where we are degrading things? When you say good results, I take it you mean successfully completing the test, not execution time of the resulting binary? Or did you do an analysis of performance, too? > There are only 11 failures: > > FAIL: MultiSource/Applications/Burg/burg.execution_time (1 of 1104) > FAIL: MultiSource/Applications/ClamAV/clamscan.execution_time (2 of 1104) > FAIL: MultiSource/Applications/lemon/lemon.execution_time (3 of 1104) > FAIL: MultiSource/Applications/sqlite3/sqlite3.execution_time (4 of 1104) > FAIL: MultiSource/Benchmarks/McCat/12-IOtest/iot...

... especially as we did not spend  >too much time optimising this. Yes, we should look into the compile-execution performance trade-off.  I have summarized some benchmarks (compile-time overhead is more than 200%) as follows: SingleSource/Benchmarks/Shootout/nestedloop, compile_time(+6355.56%), execution_time(-99.21%) SingleSource/Benchmarks/Polybench/stencils/seidel-2d/seidel-2d, compile_time(+1275.00%), execution_time (0%) SingleSource/Benchmarks/Shootout-C++/nestedloop, compile_time(+1155.56%), execution_time(-99.23%) MultiSource/Benchmarks/ASC_Sequoia/AMGmk/AMGmk, compile_time(+491.80%), executi...

Hi Renato, I've investigated a few of these for AArch64 recently, and some of the results will be applicable in the 32-bit world too. > MultiSource/Benchmarks/McCat/12-IOtest/iotest.execution_time This is because of disagreement between ABIs over whether "char" is signed. ARM says no, x86 says yes. > MultiSource/Benchmarks/MiBench/automotive-bitcount/automotive-bitcount.execution_time This is also failing on x86, I think (http://lab.llvm.org:8011/builders/clang-x86_64-debian...

There is almost certainly a bug in lnt or the makefiles. I changed the body of Burg main to the following: + printf("Hello World\n"); + return 0; I re-ran the test-suite again and got the following errors: --- Tested: 986 tests -- FAIL: MultiSource/Applications/Burg/burg.execution_time (494 of 986) FAIL: MultiSource/Applications/ClamAV/clamscan.execution_time (495 of 986) FAIL: MultiSource/Applications/lemon/lemon.execution_time (496 of 986) FAIL: MultiSource/Benchmarks/MiBench/automotive-bitcount/automotive-bitcount.exec ution_time (497 of 986) FAIL: MultiSource/Benchmarks/Mi...

Hi, I figured out how to resolve the failures. I noticed that Mountain Lion includes Bison 2.3 while Ubuntu 12.04 includes Bison 2.5. I installed Bison 2.3 from source in Ubuntu and the failures went away. I'm a little concerned that the bison version fixed all the failures I was seeing. To my knowledge the only failing test that depended on bison was Burg. It almost looks like one failure

Hi all, I have evaluated Polly's performance on LLVM test-suite with latest LLVM (r188054) and Polly (r187981).  Results can be viewed on: http://188.40.87.11:8000. There are mainly five new tests and each test is run with 10 samples: clang (run id = 27):  clang -O3 pollyBasic (run id = 28):  clang -O3 -load LLVMPolly.so pollyNoGen (run id = 29):  pollycc -O3 -mllvm -polly-optimizer=none

Hi Daniel, I'm trying to add LivermoreLoops test to the benchmark suite (tar ball attached), but I'm getting the error below: --- Tested: 2 tests -- FAIL: SingleSource/Benchmarks/LivermoreLoops/lloops.compile_time (1 of 2) FAIL: SingleSource/Benchmarks/LivermoreLoops/lloops.execution_time (2 of 2) When I use the option to only run this test: --only-test SingleSource/Benchmarks/LivermoreLoops I can see the binary and if I execute, it runs (still missing bits and bobs, but ignore that for now). I've seen some files with extension "reference_output", does that have an...
