Dominic Hamon a3b5e44c52 Remove CHECK_* from public API. 
CHECK_* are now private and used internally in the library. The test
uses have been replaced with asserts.

Fixes #62.

Chris Kennelly 2c9b29c9ff Resolve race on approx_time_ in FastClock. 
InitType should hold a lock before storing to approx_time_, which is later
read by the background worker.  When the worker is actively running (i.e., not
blocked on bg_cond_) it holds bg_mutex_.

InitType is called during benchmark setup only, so any contention induced for
the mutex should not have performance/accuracy consequences.

Chris Kennelly 77106c1f68 Statically initialize benchmark_mutex and extend its lifetime. 
RunSpecifiedBenchmarks destroys benchmark_mutex before its last usage,
typically in RemoveBenchmark during cleanup of the BenchmarkFamilies singleton.

Chris Kennelly 54e18b8992 Resolve benchmark cleanup race condition in issue #20. 
The multithreaded API for benchmarks provides that teardown can happen in
thread 0.  For this to be safe, all other threads executing the benchmark
function need to have exited.  Otherwise, thread 0 may begin to teardown shared
resources before the other threads have stopped using these resources as they
are in their last loop of while (KeepRunning()) { ... }.

This change creates a single exit point for KeepRunning() to return false.
When running a multithreaded benchmark, thread 0 blocks on KeepRunning() until
all other threads have exited.  This approach allows for there to be no change
to the user-facing API exemplified in the BM_MultiThreaded example.

Chris Kennelly 9f27edbb16 Resolve memory leak from benchmark instances in google/benchmark#17. 
This shifts registration from a global vector to a singleton that manages
benchmark destruction during shutdown.

Chris Kennelly fa908926c7 Partially resolve google/benchmark#17 by fixing regular expression leak. 
This adds a unit test to validate the wrapper without running the entirety of
benchmark_test.

Arne Beer 50f459d2c0 Unable to compile because of unused parameter 
There is a unused parameter at benchmark:866 Benchmark::MeasurePeakHeapMemory .
The function is marked as TODO and the code that uses the parameter is commented out.
I just removed the parameter so it can compile again without editing the CMake compile flags.

Felix Homann a7c57939c8 Fix cycleclock.h for gcc/ARM. 
Currently there are tests for ARMV3 and ARMV6 in cycleclock.h which are not
defined using gcc on ARM. Since there is also a cast to the unknown type
int64 I assume that the ARM code has not been tested. Therefore this patch
replaces the checks for ARMV3 and ARMV6 by checks for __ARM_ARCH. Also, the
cast to int64 is fixed by casting to int64_t.

Yusuke Suzuki 45b79c3e01 Check families is not nullptr before using it 
When there's no benchmarks, families becomes nullptr. So before touching
it, we need to ensure families is not nullptr.

Dominic Hamon 403f354423 Initial commit 
Benchmark library builds and runs but only single-threaded. Multithreaded
support needs a bit more love.

Currently requires some C++11 support (g++ 4.6.3 seems to work).
