Nicholas Hutchinson 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>.)

Nicholas Hutchinson 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.

Eric d038472c18 Refactor benchmark.cc into benchmark_register.cc and benchmark.cc (#287) 
* 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

biojppm 83561f0580 CMake: add headers to the list of source files. (#284)

Eric Fiselier 2e0796e148 Cleanup and optimize Range generation. 2016-08-28 23:15:55 -06:00
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`.
 2016-08-28 23:07:38 -06:00
Eric Fiselier cbcd7b656e Fix std::cout/std::cerr static initialization order fiasco. 
The benchmark library internals write to std::cout/std::cerr during program
startup. This can cause segfaults when the user doesn't include <iostream> in
the benchmark (which init's the streams). This patch fixes this by emitting
a dynamic initializer in every TU which initializes the streams.
 2016-08-28 22:48:48 -06:00
Eric a11fb69c89 Add --benchmark_report_aggregates_only={true|false} flag for better summary output. (#267) 2016-08-10 18:20:54 -06:00
Eric Fiselier 95dee3c699 Work around bogus GCC warning 2016-08-08 02:22:49 -06:00
Eric Fiselier c04f703ab4 Fix signed integer overflow UB in complexity computations. 
Previously the FittingCurve functions for n^2 and n^3 did the calculation
using int types. This can overflow and cause UB. This patch changes the
calculations to use std::pow to prevent this.

Also re-enable VC 2013 appveyor bot since I *hope* this is what was causing
the failures.
 2016-08-07 17:33:18 -06:00
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().
 2016-08-04 12:30:14 -07:00
Eric Fiselier 44128d87d2 Add --benchmark_out=<filename> and --benchmark_out_format=<format> options. 
These options allow you to write the output of a benchmark to the specified
file and with the specified format. The goal of this change is to help support
tooling.

Elliott Hughes b805b7c6e0 Add missing volatiles to 32-bit ARM cycleclock assembler. (#253) 
Without these, clang reorders these instructions as if they were
regular loads/stores which causes SIGILL from the kernel because
it performs all the loads before it starts testing the values.

Kai Wolf cded70a166 Add optional ms time unit for console reporter 
Some benchmarks may run a few milliseconds which makes it kind of hard to visually compare, since the currently only available nanoseconds numbers can get very large in this case. Therefore this commit adds an optional command line flag --benchmark_time_unit which lets the user choose between ns and ms time units for displaying the mean execution time.

ThreadPerCpu().

Eric Fiselier 7a767012f1 Adopt new benchmark timing internals. 
This patch adopts a new internal structure for how timings are performed.
Currently every iteration of a benchmark checks to see if it has been running
for an appropriate amount of time. Checking the clock introduces noise into
the timings and this can cause inconsistent output from each benchmark.

Now every iteration of a benchmark only checks an iteration count to see if it
should stop running. The iteration count is determined before hand by testing
the benchmark on a series of increasing iteration counts until a suitable count
is found. This increases the amount of time it takes to run the actual benchmarks
but it also greatly increases the accuracy of the results.

This patch introduces some breaking changes. The notable breaking changes are:
1. Benchmarks run on multiple threads no generate a report per thread. Instead
   only a single report is generated.
2. ::benchmark::UseRealTime() was removed and replaced with State::UseRealTime().
 2015-03-12 18:03:33 -04:00
Dominic Hamon d68127d8ad Enable UseRealTime and fix documentation for SetLabel. 
Fixes #89

UseRealTime was defined in the internal namespace by mistake.
Similarly, documentation suggested that benchmark::SetLabel should be
used to set a label, and a function was declared but not defined, while
actually the call should be 'state.SetLabel'.

This patch does two things:

1. It overhalls the static initialization in Walltime to be simplier. It uses
   a static variable inside WallTime::Now() to initialize the timer.

2. Add a logging mechanism so that the -v flag actually has meaning and
   reimplement the CHECK macros to allow extra messages to be streamed in.

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 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.

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.
