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. |

fix version recorded in releases (#1047)
* cmake: fix handling the case where `git describe` fails * cmake: fix version recorded in releases If downloaded as a tarball release, there will be no info from git to determine the release, so it ends up v0.0.0. If that's the case, we'll now use the release specified in the project() command, which needs to be updated for each new release. * cmake: add `--tags` to `git describe` That way, lightweight tags will also be taken into account, which should never hurt, but it'll help in cases where, for some mysterious reason or other, annotated tags don't make it into a clone. * update releasing.md |

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 |

[Tooling] 'display aggregates only' support. (#674)
Works as you'd expect, both for the benchmark binaries, and
the jsons (naturally, since the tests need to work):

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 |

[Tools] A new, more versatile benchmark output compare tool (#474)
* [Tools] A new, more versatile benchmark output compare tool
Sometimes, there is more than one implementation of some functionality.
And the obvious use-case is to benchmark them, which is better?
Currently, there is no easy way to compare the benchmarking results
in that case:
The obvious solution is to have multiple binaries, each one
containing/running one implementation. And each binary must use
exactly the same benchmark family name, which is super bad,
because now the binary name should contain all the info about
benchmark family...
What if i tell you that is not the solution?
What if we could avoid producing one binary per benchmark family,
with the same family name used in each binary,
but instead could keep all the related families in one binary,
with their proper names, AND still be able to compare them?
There are three modes of operation:
1. Just compare two benchmarks, what `compare_bench.py` did:
```
