These changes have already been upstreamed intoGoogle Benchmark and this patch applies the changes to the in-tree version.The main improvement in the addition of a 'compare_bench.py' script whichmakes it very easy to compare benchmarks. For example to compare the nativeSTL to libc++ you would run:`$ compare_bench.py ./util_smartptr.native.out ./util_smartptr.libcxx.out`And the output would look like:RUNNING: ./util_smartptr.native.outBenchmark Time CPU Iterations----------------------------------------------------------------BM_SharedPtrCreateDestroy 62 ns 62 ns 10937500BM_SharedPtrIncDecRef 31 ns 31 ns 23972603BM_WeakPtrIncDecRef 28 ns 28 ns 23648649RUNNING: ./util_smartptr.libcxx.outBenchmark Time CPU Iterations----------------------------------------------------------------BM_SharedPtrCreateDestroy 46 ns 46 ns 14957265BM_SharedPtrIncDecRef 31 ns 31 ns 22435897BM_WeakPtrIncDecRef 34 ns 34 ns 21084337Comparing ./util_smartptr.native.out to ./util_smartptr.libcxx.outBenchmark Time CPU-----------------------------------------------------BM_SharedPtrCreateDestroy -0.26 -0.26BM_SharedPtrIncDecRef +0.00 +0.00BM_WeakPtrIncDecRef +0.21 +0.21llvm-svn: 278147 List of files: /llvm-project-15.0.7/libcxx/benchmarks/unordered_set_operations.bench.cpp Tue, 09 Aug 2016 18:56:48 +0000 Eric Fiselier <eric@efcs.ca> http://172.16.0.5:8080/history/llvm-project-15.0.7/libcxx/benchmarks/unordered_set_operations.bench.cpp#1a06fe5f Skip chash computation in insert/emplace if the unconstrained hash matches.llvm-svn: 276549 List of files: /llvm-project-15.0.7/libcxx/benchmarks/unordered_set_operations.bench.cpp Sun, 24 Jul 2016 06:22:25 +0000 Eric Fiselier <eric@efcs.ca> http://172.16.0.5:8080/history/llvm-project-15.0.7/libcxx/benchmarks/unordered_set_operations.bench.cpp#b08d8b18 [libcxx] Add support for benchmark tests using Google Benchmark.Summary:This patch does the following:1. Checks in a copy of the Google Benchmark library into the libc++ repo under `utils/google-benchmark`.2. Teaches libc++ how to build Google Benchmark against both (A) in-tree libc++ and (B) the platforms native STL.3. Allows performance benchmarks to be built as part of the libc++ build.Building the benchmarks (and Google Benchmark) is off by default. It must be enabled using the CMake option `-DLIBCXX_INCLUDE_BENCHMARKS=ON`. When this option is enabled the tests under `libcxx/benchmarks` can be built using the `libcxx-benchmarks` target.On Linux platforms where libstdc++ is the default STL the CMake option `-DLIBCXX_BUILD_BENCHMARKS_NATIVE_STDLIB=ON` can be used to build each benchmark test against libstdc++ as well. This is useful for comparing performance between standard libraries.Support for benchmarks is currently very minimal. They must be manually run by the user and there is no mechanism for detecting performance regressions.Known Issues:* `-DLIBCXX_INCLUDE_BENCHMARKS=ON` is only supported for Clang, and not GCC, since the `-stdlib=libc++` option is needed to build Google Benchmark.Reviewers: danalbert, dberlin, chandlerc, mclow.lists, jroelofsSubscribers: chandlerc, dberlin, tberghammer, danalbert, srhines, hfinkelDifferential Revision: https://reviews.llvm.org/D22240llvm-svn: 276049 List of files: /llvm-project-15.0.7/libcxx/benchmarks/unordered_set_operations.bench.cpp Tue, 19 Jul 2016 23:07:03 +0000 Eric Fiselier <eric@efcs.ca> http://172.16.0.5:8080/history/llvm-project-15.0.7/libcxx/benchmarks/unordered_set_operations.bench.cpp#c835c12f Add unordered_map::insert benchmark test and rename filellvm-svn: 274424 List of files: /llvm-project-15.0.7/libcxx/benchmarks/unordered_set_operations.bench.cpp Sat, 02 Jul 2016 05:30:54 +0000 Eric Fiselier <eric@efcs.ca>
