Jilin Zhou d205ead299 [#774] implement GetNumCPUs(), GetCPUCyclesPerSecond(), and GetCacheSizes() (#775)
- On qnx platform, cpu and cache info is stored in a syspage struct which
  is different from other OS platform.
- The fix has been verified on an aarch64 target running qnx 7.0.
Fixes #774

Jilin Zhou 0ae233ab23 [#766] add x-compile support for QNX SDP7 (#770)
Since googletest already supports x-compilation for QNX, it is nice to
 have google benchmark support it too.

Daniel Kraft 97393e5ef8 Add -lpthread to pkg-config Libs.private. (#755)
Since pthread is required at least for GCC (according to the
documentation), this should be reflected by the pkg-config file.

The same is, for instance, also done by the gflags library:

Reid Kleckner dc10645549 Set CMP0048 policy before project() to silence warnings (#750)
If this policy isn't set, CMake emits a large warning when project() is
called from a cmake subdirectory.

This came up when the benchmark library was added to the LLVM build, and
it was reported in https://llvm.org/PR38874. This patch was the fix I
applied locally to fix the issue, and I wanted to send it upstream.

Print at least three significant digits for times. (#701)
Some benchmarks are particularly sensitive and they run in less than
a nanosecond. In order for the console reporter to provide meaningful
output for such benchmarks it needs to be able to display the times
using more resolution than a single nanosecond.

This patch changes the console reporter to print at least three
significant digits for all results.

Unlike the initial attempt, this patch does not align the decimal point.

Remove use of std::tmpnam. (#734)
std::tmpnam is deprecated and its use is discouraged. For our purposes
in the tests, we really just need a file name which is unlikely to
exist.

This patch converts the tests to using a dummy random file name
generator, which should hopefully avoid name conflicts.

Aggregates: use non-aggregate count as iteration count. (#706)
It is incorrect to say that an aggregate is computed over
run's iterations, because those iterations already got averaged.
Similarly, if there are N repetitions with 1 iterations each,
an aggregate will be computed over N measurements, not 1.
Thus it is best to simply use the count of separate reports.

Fixes #586.

[NFC] BenchmarkRunner: always populate *_report_aggregates_only bools. (#708)
It is better to let the RunBenchmarks(), report() decide
whether to actually *only* output aggregates or not,
depending on whether there are actually aggregates.

It's subtle indeed.

Previously, `BenchmarkRunner()` always said that "if there are no repetitions,
then you should never output only the repetitions". And the `report()` simply assumed
that the `report_aggregates_only` bool it received makes sense, and simply used it.

Now, the logic is the same, but the blame has shifted.
`BenchmarkRunner()` always propagates what those benchmarks would have wanted
to happen wrt the aggregates. And the `report()` lambda has to actually consider
both the `report_aggregates_only` bool, and it's meaningfulness.

To put it in the context of the patch series - if the repetition count was `1`,
but `*_report_aggregates_only` was set to `true`, and we capture each iteration separately,
then we will compute the aggregates, but then output everything, both the iteration,
and aggregates, despite `*_report_aggregates_only` being set to `true`.

Ilya A. Kriveshko 8503dfe537 benchmark_color: fix auto option (#559) (#699)
As prevously written, "--benchmark_color=auto" was treated as true,
because IsTruthyFlagValue("auto") returned true.  The fix is to
rely on IsColorTerminal test only if the flag value is "auto",
and fall back to IsTruthyFlagValue otherwise.  I also integrated
force_no_color check into the same block.

[NFC] Refactor RunBenchmark() (#690)
Ok, so, i'm still trying to get to the state when it will be a trivial change to report all the separate iterations.
The old code (LHS of the diff) was rather convoluted i'd say.
I have tried to refactor it a bit into *small* logical chunks, with proper comments.
As far as i can tell, i preserved the intent of the code, what it was doing before.
The road forward still isn't clear, but i'm quite sure it's not with the old code :)

[Tooling] Rewrite generate_difference_report(). (#678)
My knowledge of python is not great, so this is kinda horrible.

Two things:
1. If there were repetitions, for the RHS (i.e. the new value) we were always using the first repetition,
    which naturally results in incorrect change reports for the second and following repetitions.
    And what is even worse, that completely broke U test. :(
2. A better support for different repetition count for U test was missing.
    It's important if we are to be able to report 'iteration as repetition',
    since it is rather likely that the iteration count will mismatch.

Now, the rough idea on how this is implemented now. I think this is the right solution.
1. Get all benchmark names (in order) from the lhs benchmark.
2. While preserving the order, keep the unique names
3. Get all benchmark names (in order) from the rhs benchmark.
4. While preserving the order, keep the unique names
5. Intersect `2.` and `4.`, get the list of unique benchmark names that exist on both sides.
6. Now, we want to group (partition) all the benchmarks with the same name.
   ```
   BM_FOO:
       [lhs]: BM_FOO/repetition0 BM_FOO/repetition1
       [rhs]: BM_FOO/repetition0 BM_FOO/repetition1 BM_FOO/repetition2
   ...
   ```
   We also drop mismatches in `time_unit` here.
   _(whose bright idea was it to store arbitrarily scaled timers in json **?!** )_
7. Iterate for each partition
7.1. Conditionally, diff the overlapping repetitions (the count of repetitions may be different.)
7.2. Conditionally, do the U test:
7.2.1. Get **all** the values of `"real_time"` field from the lhs benchmark
7.2.2. Get **all** the values of `"cpu_time"` field from the lhs benchmark
7.2.3. Get **all** the values of `"real_time"` field from the rhs benchmark
7.2.4. Get **all** the values of `"cpu_time"` field from the rhs benchmark
          NOTE: the repetition count may be different, but we want *all* the values!
7.2.5. Do the rest of the u test stuff
7.2.6. Print u test
8. ???
9. **PROFIT**!

Martin Storsjö 439d6b1c2a Include sys/time.h for cycleclock.h when building on MinGW (#680)
When building for ARM, there is a fallback codepath that uses
gettimeofday, which requires sys/time.h.

The Windows SDK doesn't have this header, but MinGW does have it.
Thus, this fixes building for Windows on ARM with MinGW
headers/libraries, while Windows on ARM with the Windows SDK still
is broken.

Un-deprecate [SG]et{Item,Byte}sProcessed, re-implement as custom counters. (#676)
As discussed with @dominichamon and @dbabokin, sugar is nice.
Well, maybe not for the health, but it's sweet.
Alright, enough puns.

A special care needs to be applied not to break csv reporter. UGH.
We end up shedding some code over this.
We no longer specially pretty-print them, they are printed just like the rest of custom counters.

Fixes #627.

Track two more details about runs - the aggregate name, and run name. (#675)
This is related to @BaaMeow's work in https://github.com/google/benchmark/pull/616 but is not based on it.

Two new fields are tracked, and dumped into JSON:
* If the run is an aggregate, the aggregate's name is stored.
  It can be RMS, BigO, mean, median, stddev, or any custom stat name.
* The aggregate-name-less run name is additionally stored.
  I.e. not some name of the benchmark function, but the actual
  name, but without the 'aggregate name' suffix.

This way one can group/filter all the runs,
and filter by the particular aggregate type.

I *might* need this for further tooling improvement.
Or maybe not.
But this is certainly worthwhile for custom tooling.

*Display* aggregates only. (#665)
There is a flag 
d9cab612e4/src/benchmark.cc (L75-L78)
and a call
d9cab612e4/include/benchmark/benchmark.h (L837-L840)
But that affects everything, every reporter, destination:
d9cab612e4/src/benchmark.cc (L316)


It would be quite useful to have an ability to be more picky.


More specifically, i would like to be able to only see the aggregates in the on-screen output,
but for the file output to still contain everything. The former is useful in case of a lot of repetition
(or even more so if every iteration is reported separately), while the former is **great** for tooling.

Fixes https://github.com/google/benchmark/issues/664

Roman Lebedev f274c503e1 Backport LLVM's r341717 "Fix flags used to compile benchmark library with clang-cl" (#673)
`MSVC` is true for clang-cl, but `"${CMAKE_CXX_COMPILER_ID}" STREQUAL
"MSVC"` is false, so we would enable -Wall, which means -Weverything
with clang-cl, and we get tons of undesired warnings.

Use the simpler condition to fix things.
