Fix #342: DoNotOptimize causes compile errors on older GCC versions. (#398) * Fix #342: DoNotOptimize causes compile errors on older GCC versions. DoNotOptimize uses inline assembly contraints to tell the compiler what the type of the input variable. The 'g' operand allows the input to be any register, memory, or immediate integer operand. However this constraint seems to be too weak on older GCC versions, and certain inputs will cause compile errors. This patch changes the constraint to 'X', which is documented as "any operand whatsoever is allowed". This appears to fix the issues with older GCC versions. However Clang doesn't seem to like "X", and will attempt to put the input into a register even when it can't/shouldn't; causing a compile error. However using "g" seems to work like "X" with GCC, so for this reason Clang still uses "g". * Try alternative formulation to placate GCC

Enable <cassert> by removing -DNDEBUG when running the tests. In non-debug builds CMake automatically adds -DNDEBUG, this means that uses of `assert` in the tests are disabled for non-debug builds. Obviously we want these tests to run, regardless of configuration. This patch strips -DNDEBUG during non-debug builds and adds -UNDEBUG just to be sure.

Add tests to verify assembler output -- Fix DoNotOptimize. (#530) * Add tests to verify assembler output -- Fix DoNotOptimize. For things like `DoNotOptimize`, `ClobberMemory`, and even `KeepRunning()`, it is important exactly what assembly they generate. However, we currently have no way to test this. Instead it must be manually validated every time a change occurs -- including a change in compiler version. This patch attempts to introduce a way to test the assembled output automatically. It's mirrors how LLVM verifies compiler output, and it uses LLVM FileCheck to run the tests in a similar way. The tests function by generating the assembly for a test in CMake, and then using FileCheck to verify the // CHECK lines in the source file are found in the generated assembly. Currently, the tests only run on 64-bit x86 systems under GCC and Clang, and when FileCheck is found on the system. Additionally, this patch tries to improve the code gen from DoNotOptimize. This should probably be a separate change, but I needed something to test. * Disable assembly tests on Bazel for now * Link FIXME to github issue * Fix Tests on OS X * fix strip_asm.py to work on both Linux and OS X like targets

[RFC] Adding API for setting/getting benchmark_filter flag? (#1254) * [RFC] Adding API for setting/getting benchmark_filter flag? This PR is more of a Request-for-comment - open to other ideas/suggestions as well. Details: This flag has different implementations(absl vs benchmark) and since the proposal to add absl as a dependency was rejected, it would be nice to have a reliable (and less hacky) way to access this flag internally. (Actually, reading it isn't much a problem but setting it is). Internally, we have a sizeable number users to use absl::SetFlags to set this flag. This will not work with benchmark-flags. Another motivation is that not all users use the command line flag. Some prefer to programmatically set this value. * fixed build errors * fix lints again * per discussion: add additional RunSpecifiedBenchmarks instead. * add tests * fix up tests * clarify comment * fix stray : in test * more assertion in test * add test file to test/CMakeLists.txt * more test * make test ISO C++ compliant * fix up BUILD file to pass the flag

Adopt new benchmark timing internals. This patch adopts a new internal structure for how timings are performed. Currently every iteration of a benchmark checks to see if it has been running for an appropriate amount of time. Checking the clock introduces noise into the timings and this can cause inconsistent output from each benchmark. Now every iteration of a benchmark only checks an iteration count to see if it should stop running. The iteration count is determined before hand by testing the benchmark on a series of increasing iteration counts until a suitable count is found. This increases the amount of time it takes to run the actual benchmarks but it also greatly increases the accuracy of the results. This patch introduces some breaking changes. The notable breaking changes are: 1. Benchmarks run on multiple threads no generate a report per thread. Instead only a single report is generated. 2. ::benchmark::UseRealTime() was removed and replaced with State::UseRealTime().

Support optional, user-directed collection of performance counters (#1114) * Support optional, user-directed collection of performance counters The patch allows an engineer wishing to drill into the root causes of a regression, for example. Currently, only single threaded runs are supported. The feature is a build-time opt in, and then a runtime opt in. The engineer may run the benchmark executable, passing a list of performance counter names (using libpfm's naming scheme) at the command line. The counter values will then be collected and reported back as UserCounters. This is different from #240 in that it is a benchmark user opt-in, and the counter collection is transparent to the benchmark. Currently, this is only supported on platforms where libpfm is supported. libpfm: http://perfmon2.sourceforge.net/ * 'Use' values param in Snapshot when BENCHMARK_OS_WINDOWS This is to avoid unused parameter warning-as-error * Added missing include for <vector> in perf_counters.cc * Moved doc to docs * Added license blurbs

Coverage support with LCOV and GCOV This patch adds a `coverage` target that allows coverage statisitics to be retrieved for the project. It requires that lcov and gcov is installed and that the generator is unix makefiles but this can be improved upon in future releases. To make it work use the coverage build type: ``` cmake -DCMAKE_BUILD_TYPE=Coverage . make coverage ```

Add support for GTest based unit tests. (#485) * Add support for GTest based unit tests. As Dominic and I have previously discussed, there is some need/desire to improve the testing situation in Google Benchmark. One step to fixing this problem is to make it easier to write unit tests by adding support for GTest, which is what this patch does. By default it looks for an installed version of GTest. However the user can specify -DBENCHMARK_BUILD_EXTERNAL_GTEST=ON to instead download, build, and use copy of gtest from source. This is quite useful when Benchmark is being built in non-standard configurations, such as against libc++ or in 32 bit mode.

Alias CMake Targets. Fixes #921 (#926) * add Jordan Williams to both CONTRIBUTORS and AUTHORS * alias benchmark libraries Provide aliased CMake targets for the benchmark and benchmark_main targets. The alias targets are namespaced under benchmark::, which is the namespace when they are exported. I chose not to use either the PROJECT_NAME or the namespace variable but to hard-code the namespace. This is because the benchmark and benchmark_main targets are hard-coded by name themselves. Hard-coding the namespace is also much cleaner and easier to read. * link to aliased benchmark targets It is safer to link against namespaced targets because of how CMake interprets the double colon. Typo's will be caught by CMake at configuration-time instead of during compile / link time. * document the provided alias targets * add "Usage with CMake" section in documentation This section covers linking against the alias/import CMake targets and including them using either find_package or add_subdirectory. * format the "Usage with CMake" README section Added a newline after the "Usage with CMake" section header. Dropped the header level of the section by one to make it a direct subsection of the "Usage" section. Wrapped lines to be no longer than 80 characters in length.

CMake: codedrop of googletest cmake magic from me (#809) https://github.com/google/benchmark/pull/801 is stuck with some cryptic cmake failure due to some linking issue between googletest and threading libraries. I suspect that is mostly happening because of the, uhm, intentionally extremely twisted-in-the-brains approach that is being used to actually build the library as part of the buiild, except without actually building it as part of the build. If we do actually build it as part of the build, then all the transitive dependencies should magically be in order, and maybe everything will just work. This new version of cmake magic was written by me in https://github.com/darktable-org/rawspeed/blob/0e22f085c57cd629983c7351c598abd744b421b5/cmake/Modules/GoogleTest.cmake.in https://github.com/darktable-org/rawspeed/blob/0e22f085c57cd629983c7351c598abd744b421b5/cmake/Modules/GoogleTest.cmake, based on the official googletest docs and LOTS of experimentation.

Random interleaving of benchmark repetitions - the sequel (fixes #1051) (#1163) Inspired by the original implementation by Hai Huang @haih-g from https://github.com/google/benchmark/pull/1105. The original implementation had design deficiencies that weren't really addressable without redesign, so it was reverted. In essence, the original implementation consisted of two separateable parts: * reducing the amount time each repetition is run for, and symmetrically increasing repetition count * running the repetitions in random order While it worked fine for the usual case, it broke down when user would specify repetitions (it would completely ignore that request), or specified per-repetition min time (while it would still adjust the repetition count, it would not adjust the per-repetition time, leading to much greater run times) Here, like i was originally suggesting in the original review, i'm separating the features, and only dealing with a single one - running repetitions in random order. Now that the runs/repetitions are no longer in-order, the tooling may wish to sort the output, and indeed `compare.py` has been updated to do that: #1168.

Support optional, user-directed collection of performance counters (#1114) * Support optional, user-directed collection of performance counters The patch allows an engineer wishing to drill into the root causes of a regression, for example. Currently, only single threaded runs are supported. The feature is a build-time opt in, and then a runtime opt in. The engineer may run the benchmark executable, passing a list of performance counter names (using libpfm's naming scheme) at the command line. The counter values will then be collected and reported back as UserCounters. This is different from #240 in that it is a benchmark user opt-in, and the counter collection is transparent to the benchmark. Currently, this is only supported on platforms where libpfm is supported. libpfm: http://perfmon2.sourceforge.net/ * 'Use' values param in Snapshot when BENCHMARK_OS_WINDOWS This is to avoid unused parameter warning-as-error * Added missing include for <vector> in perf_counters.cc * Moved doc to docs * Added license blurbs

Add tests to verify assembler output -- Fix DoNotOptimize. (#530) * Add tests to verify assembler output -- Fix DoNotOptimize. For things like `DoNotOptimize`, `ClobberMemory`, and even `KeepRunning()`, it is important exactly what assembly they generate. However, we currently have no way to test this. Instead it must be manually validated every time a change occurs -- including a change in compiler version. This patch attempts to introduce a way to test the assembled output automatically. It's mirrors how LLVM verifies compiler output, and it uses LLVM FileCheck to run the tests in a similar way. The tests function by generating the assembly for a test in CMake, and then using FileCheck to verify the // CHECK lines in the source file are found in the generated assembly. Currently, the tests only run on 64-bit x86 systems under GCC and Clang, and when FileCheck is found on the system. Additionally, this patch tries to improve the code gen from DoNotOptimize. This should probably be a separate change, but I needed something to test. * Disable assembly tests on Bazel for now * Link FIXME to github issue * Fix Tests on OS X * fix strip_asm.py to work on both Linux and OS X like targets
