This patch fixes compilation on Solaris, addressing the problems reported
in Issue #1499:
* Provide `HOST_NAME_MAX` definition.
* Match `sysconf(3C)` return type.
* Avoid `-Wcast-qual` warnings with `libkstat(3KSTAT)` functions.
* Avoid clash with `<floatingpoint.h>` `single` typedef.
* Add option to set the default time unit globally
This commit introduces the `--benchmark_time_unit={ns|us|ms|s}` command line argument. The argument only affects benchmarks where the time unit is not set explicitly.
* Update AUTHORS and CONTRIBUTORS
* Test `SetDefaultTimeUnit`
* clang format
* Use `GetDefaultTimeUnit()` for initializing `TimeUnit` variables
* Review fixes
* Export functions
* Add comment
* Fix#1159 Harmonize the types between the loop counter and the vector of indices
The loop counter is a size_t, but they're stored in a vector-of-int leading to
potential overflow warnings. In order to avoid accidental run-time overflow
this change modifies the vector type, rather than the loop counter.
* Fix up line endings
* Update AUTHORS

* Implement custom benchmark name
The benchmark's name can be changed using the Name() function
which internally uses SetName().
* Update AUTHORS and CONTRIBUTORS
* Describe new feature in README
* Move new name function up
Fixes#1106
As per discussions in here [1], LLVM is going to get backend support on
Motorola 68000 series CPUs (a.k.a M68K or M680x0). So it's necessary to
add CycleTimer implementation here, which is simply using `gettimeofday`
same as MIPS. This fixes#1049

* Add CartesianProduct with associated test
* Use CartesianProduct in Ranges to avoid code duplication
* Add new cartesian_product_test to CMakeLists.txt
* Update AUTHORS & CONTRIBUTORS
* Rename CartesianProduct to ArgsProduct
* Rename test & fixture accordingly
* Add example for ArgsProduct to README
* add Jordan Williams to both CONTRIBUTORS and AUTHORS
* alias benchmark libraries
Provide aliased CMake targets for the benchmark and benchmark_main targets.
The alias targets are namespaced under benchmark::, which is the namespace when they are exported.
I chose not to use either the PROJECT_NAME or the namespace variable but to hard-code the namespace.
This is because the benchmark and benchmark_main targets are hard-coded by name themselves.
Hard-coding the namespace is also much cleaner and easier to read.
* link to aliased benchmark targets
It is safer to link against namespaced targets because of how CMake interprets the double colon.
Typo's will be caught by CMake at configuration-time instead of during compile / link time.
* document the provided alias targets
* add "Usage with CMake" section in documentation
This section covers linking against the alias/import CMake targets and including them using either find_package or add_subdirectory.
* format the "Usage with CMake" README section
Added a newline after the "Usage with CMake" section header.
Dropped the header level of the section by one to make it a direct subsection of the "Usage" section.
Wrapped lines to be no longer than 80 characters in length.
* Add DEBUG_POSTFIX to libraries.
Makes it possible to install Debug and Release versions on the
same system. Without this, there were only linker errors when using
the wrong configuration.
* Update CONTRIBUTORS and AUTHORS according to guide
* Update AUTHORS and CONTRIBUTORS
* Fix WSL self-test failures
Some of the benchmark self-tests expect and check for a particular
output format from the benchmark library. The numerical values must
not be infinity or not-a-number, or the test will report an error.
Some of the values are computed bytes-per-second or items-per-second
values, so these require that the measured CPU time for the test to be
non-zero. But the loop that is being measured was empty, so the
measured CPU time for the loop was extremely small. On systems like
Windows Subsystem for Linux (WSL) the timer doesn't have enough
resolution to measure this, so the measured CPU time was zero.
This fix just makes sure that these tests have something within the
timing loop, so that the benchmark library will not decide that the
loop takes zero CPU time. This makes these tests more robust, and in
particular makes them pass on WSL.
Created BenchmarkName class which holds the full benchmark
name and allows specifying and retrieving different components
of the name (e.g. ARGS, THREADS etc.)
Fixes#730.
* Add myself to CONTRIBUTORS under the corp CLA for Stripe, Inc.
* Add support for building with Bazel.
Limitations compared to existing CMake rules:
* Defaults to using C++11 `<regex>`, with an override via Bazel flag
`--define` of `google_benchmark.have_regex`. The TravisCI config sets
the regex implementation to `posix` because it uses ancient compilers.
* Debug vs Opt mode can't be set per test. TravisCI runs all the tests
in debug mode to satisfy `diagnostics_test`, which depends on `CHECK`
being live.
* Set Bazel workspace name so other repos can refer to it by stable name.
This is recommended by the Bazel style guide to avoid each dependent
workspace defining its own name for the dependency.
* Fix reading CPU info from file
Macro CHECK do nothing for release mode, meaning it doesn't invoke the
arguments
* Add myself to AUTHORS and CONTRIBUTORS
* 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

* bytes_per_second and items_per_second are now in the UserCounters class

* 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
* 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
get_git_version CMake function uses 'git' command directly, instead of
GIT_EXECUTABLE variable. This causes CMake errors while generating
project files in environments, where 'git' command is not present
in PATH.
