94c512c043 Replace int64_t usages with 'int' instead. (#359)
Previously the constants used for converting between
different units of time were declared using int64_t. However
we should only use explicitly sized integer types when they
are required, and should use 'int' everwhere else, and there is
no good reason to use int64_t here.

For that reason this patch changes the type of the constants.
This should help address issue #354 as well.

9b92ed76a8 Fix ICC compiler warnings (#358)
fixes #354

The build fails with ICC17 because of warnings and Werror. What is the correct solution to fix it?
Should a patch

disable Werror for ICC (or maybe all non known compilers)
disable the false postive warnings for all files. This could be done using:
add_cxx_compiler_flag(-wd2102) #ICC17u2: Many false positives for Wstrict-aliasing
add_cxx_compiler_flag(-wd2259) #ICC17u2: non-pointer conversion from "long" to "int" may lose significant bits (even for explicit static cast, sleep.cc(44))
add_cxx_compiler_flag(-wd654) #ICC17u2: overloaded virtual function "benchmark::Fixture::SetUp" is only partially overridden (because of deprecated overload)
disable warnings at file level or some other granularity

f682f7e9a4 Implement ClobberMemory() and fix DoNotOptimize on MSVC. (#352)
I recently learned Windows provides a function called _ReadWriteBarrier
which is literally ClobberMemory under a different name. This patch
uses it to implement ClobberMemory under MSVC.

8ae6448cc7 Fix std::string detection hack for SetLabel.
Previously benchmark_api.h wasn't allowed to include standard library
headers. For this reason SetLabel had a hack to accept std::string
without including <string>. The hack worked by attempting to detect
the injected class name `basic_string`. However Clang has changed
it's behavior regarding injected class names so this hack no longer
works.

This patch removes the hack and replaces it with a function that
actually names std::string. However we still cannot pass std::string
across the dylib boundary because of libstdc++'s dual C++11 ABI.

9e34655602 Rename BenchmarkCounters to UserCounters (#346)

a9a66c85bb Add user-defined counters. (#262)
* Added user counters, and move use of bytes_processed and items_processed to user counter logic.

Each counter is a string-value pair. The counters were
made available through the State class. Two helper virtual
methods were added to the Fixture class to allow convenient
initialization and termination of the counters: InitState()
and TerminateState(). The reporting of the counters is buggy
and is still a work in progress, to be completed in the next commits.

* fix bad removal of BenchmarkCounters code during the merge

* add myself to AUTHORS/CONTRIBUTORS

* fix printing to std::cout in csv_reporter

* bytes_per_second and items_per_second are now in the UserCounters class

* add user counters to json reporter

* moving bytes_per_second and items_per_second to their old state

* console reporter dealing ok with user counters.

* update unit tests for user counters

* CSVReporter now prints user counters too.

* cleanup user counters

* reverted changes to cmake files which should have gone into later commits

* fixture_test: fix gcc 4.6 compilation

* remove ctor with default argument

see https://github.com/google/benchmark/pull/262#discussion_r72298055

246ee86428 Disable iOS CPU Frequency readout (#335)
* Add macro definition for iOS

Add an additional macro definition for iOS.
iOS is defined as a Mac OSX invariant in the TargetConditionals include,
thus we treat it as a subset of OSX within the defines.

* Skip error for hw.cpufrequency on iOS

hw.cpufrequency is not available on iOS devices. As there is no way to reliably
retrieve the CPU frequency on iOS we are printing out a warning
that we were unable to detect the CPU frequency and set it to 0.

This only disables cpu frequency readouts on actual physical iOS devices.
Running this code on the simulator still gives the cpu architecture of
the host computer as the simulator passes down the sysctl calls to OSX.

2373382284 Rewrite compare_bench.py argument parsing.
This patch cleans up a number of issues with how compare_bench.py handled
the command line arguments.

* Use the 'argparse' python module instead of hand rolled parsing. This gives
  better usage messages.

* Add diagnostics for certain --benchmark flags that cannot or should not
  be used with compare_bench.py (eg --benchmark_out_format=csv).

* Don't override the user specified --benchmark_out flag if it's provided.

In future I would like the user to be able to capture both benchmark output
files, but this change is big enough for now.

This fixes issue #313.

917b86e615 Auto-detect whether Benchmark should produce colorized output (#126)
* Auto-detect whether to produce colorized output

Rename --color_print to --benchmark_color for consistency with the other
flags (and Google Test). Old flag name is kept around for compatibility.

The --benchmark_color/--color_print flag takes a third option, "auto",
which is the new default. In this mode, we attempt to auto-detect
whether to produce colorized output. (The logic for deciding whether to
use colorized output was lifted from GTest:
<https://github.com/google/googletest/blob/master/googletest/src/gtest.cc#L2925>.)

b826143ac2 Flush reporters' output streams after writing a benchmark run (#288)
If a reporter's output stream isn't line-buffered (e.g. it's not writing
to a terminal) then it can be some time before a write to it becomes
visible.

This is problematic if, say, you're wanting to use tail -f to view the
file written to via --benchmark_out. Or if the application crashes,
leaving you with no results.

Addressed by flushing the reporters' output streams whenever we invoke
methods that may write to them.

* Refactor benchmark.cc into benchmark_register.cc and benchmark_run.cc

The benchmark.cc file is getting really big and it contains a bunch of
unrelated components. This patch separates the files into two separate
parts. The "runtime" parts and the "registration" parts.

This patch also removes the PIMPL used by Benchmark. Previously we couldn't
have STL types in the interface but now we can. Therefore there is no reason
to keep BenchmarkImp.
