Joao Paulo Magalhaes 6452883027 Unit testing: add facilities to check benchmark results.
This is needed for examining the values of user counters (needed
for #348). It is also needed for checking the values of standard
benchmark results like items_processed or complexities (for example,
checking the standard deviation is needed for unit testing #357
as discussed in #362).

Joao Paulo Magalhaes 693a43013d User counters: add more unit tests. ...
The tests are still missing a way to check actual validity of
numerical results; this will be done next. As they currently are,
the tests pass, but the problem detected with #378 is still
standing and the results with non-standard counters are wrong.

Eric 74b24058ad Add Benchmark::Iterations for explicit iteration count control - Fixes #370 (#373)
* Add Benchmark::Iterations for explicitly specifying the number of iterations to use.

Eric Fiselier 7f87c98d36 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.

rolandschulz 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

jpmag 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

* use (auto-defined) BENCHMARK_HAS_CXX11 instead of BENCHMARK_INITLIST.

far-reaching so I rolled those back.

Eric Fiselier db1af86d16 Fix out-of-bounds std::vector access.
In the `Ranges(...)` generation code a "control" vector which stores
the current index for each range passed to `Ranges`. Previously this vector
was incorrectly initialized to the size of the subranges not the number
of subranges.

Additionally this patch suppresses unused warnings generated by
`stream_init_anchor`.

Eric Fiselier ee54a3f03e Rework Appveyor config
Currently the Appveyor bot is a PIT. It never passes and it often hangs

Eric Fiselier 8267117a92 Add ASAN and UBSAN builders to travis for both GCC and Clang.
This patch adds new builders that test against GCC 6 and Clang 3.8 respectivly.
They also enable both address and undefined sanitizer. MSAN currently won't work
since it requires a sanitized STL.

VC 2013 injects valid when  assigning an initializer list to std::set.

instead of the assignment operators.

Marcin Kolny dfe0260754 Support multiple ranges in the benchmark (#257)
* Support multiple ranges in the benchmark

google-benchmark library allows to provide up to two ranges to the
benchmark method (range_x and range_y). However, in many cases it's not
sufficient. The patch introduces multi-range features, so user can easily
define multiple ranges by passing a vector of integers, and access values
through the method range(i).

* Remove redundant API

Functions State::range_x() and State::range_y() have been removed. They should
be replaced by State::range(0) and State::range(1).
Functions Benchmark::ArgPair() and Benchmark::RangePair() have been removed.
They should be replaced by Benchmark::Args() and Benchmark::Ranges().

Eric Fiselier 1bd62bd0be Revert "Workaround missing std::this_thread::sleep_for function in tests."
GCC 4.6 doesn't provide std::chrono::steady_clock and GCC 4.7 doesn't provide
std::this_thread::sleep_for. I would prefer to support GCC 4.7 but I'm
reverting this since the bots are GCC 4.6.

This reverts commit c5f454957d.
