* 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.

* remove std::string dependency on public API - changed counter name storage to char*
* Counter ctor: use overloads instead of default arguments
discussion:

* Use raw pointers to remove dependency on std::vector from public API .
For more info, see discussion at https://github.com/google/benchmark/pull/262#discussion_r72319678 .
* Move counter implementation from benchmark.cc to counter.cc.
See discussion: https://github.com/google/benchmark/pull/262#discussion_r72298980 .
* Remove unused (commented-out) code.
* Moved thread counters to ThreadStats.
* Counters: fixed copy and move constructors.
* Counter: use an inplace buffer for small names.
* benchmark_test: move counters test out of CXX11 preprocessor conditional.
* Counter: fix VS2013 compilation error in char[] initialization.
* Fix typo.
* Expose counters from State.
See discussion: https://github.com/google/benchmark/pull/262#issuecomment-237156951
* Changed counters interface to map-like.
* Fix printing of user counters in ConsoleReporter.
* Applied clang-format to counter.cc and console_reporter.cc.
Command was `clang-format -style=Google -i counter.cc console_reporter.cc`
I also applied to all other files, but the changes were very
far-reaching so I rolled those back.
* Rename Counter::Flags_e to Counter::Flags
* Fix use of reserved names in Counter and BenchmarkCounters.
* Counter: Fix move ctor bug + change order of members.
* Fixture: remove tentative methods InitState() and TerminateState().
* Update fixture_test to the new Fixture interface.
* BenchmarkCounters: fixed a bug in the move ctor. Remove call to CHECK_LT().
CHECK_LT() was making the size_t lookup take ~double the time of a string lookup!
* BenchmarkCounters: add option to not print zero counters (defaults to false).
* Add test to compare counter storage and access with std::map.
* README: clarify cost of counter access modes.
* move counter access test to an own test.
* BenchmarkCounters: add move Insert()
* Counters access test: add accelerated lookup by name.
* Fix old range syntax.
* Fix missing include of cstdio
* Fix Visual Studio warning
* VS2013 and lower: fix use of snprintf()
* VS2013: fix use of char[] as a member of std::pair<>.
* change counter storage to std::map
* Remove skipZeroCounters logic
* Fix VS compilation error.
* Implemented request changes to PR #262.
* PR #262: More requested changes.
* README: cleanup counter text.
* PR #262: remove clang-format changes for preexisting code
* Complexity+Counters: fix counter flags which were being ignored.
* Document all Counter::Flag members
* fixed loss of counter values
* ConsoleReporter: remove tabular printing of user counters.
* ConsoleReporter: header printing should not be contingent on user counter names.
* Minor white space and alignment fixes.
* cxx03_test + counters: reuse the BM_empty() function.
* user counters: add note to README on how counters are gathered across threads
* Implement cycleclock::Now for PNaCl
* Make cycleclock::Now compatible with NaCl/ARM
* Support Emscripten (Asm.js, WebAssembly)
* Rearrange #ifs from to handle specific cases first
* DoNotOptimize without inline asm for Emscripten & PNaCl
* 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.
* BENCHMARK_MAIN() now reports unrecognised command-line flags (see google/benchmark#320)
* add benchmark::ReportUnrecognizedArguments()
Update BENCHMARK_MAIN() to use ReportUnrecognizedArguments() instead of
having the reporting code directly in the macro.
See issue google/benchmark#320 for reference
* let's stick to american english -- fix type in ReportUnrecognizedArguments()
* make ReportUnrecognizedArguments() print to stderr
* make ReportUnrecognizedArguments() return true if any arguments have been reported (i.e. argc > 1)
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.
* Test bytes_per_second and items_per_second.
* Test SetLabel.
* Reformat.
* Make State::error_occurred_ private.
* Fix tests with floats.
* Merge private blocks
* 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>.)
* Update CONTRIBUTORS, AUTHORS
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.
* add missing include
* rework windows timers again
* Guard timespec on older Windows versions
* Remove old thread safety annotation workarounds
