Having the copts set on a per-target level can lead to ODR violations
in some cases. Avoid this by ensuring the regex engine is picked
through compiler intrinsics in the header directly.
* Add Solaris support
Define BENCHMARK_OS_SOLARIS for Solaris.
Platform specific implementations added:
* number of CPUs detection
* CPU cycles per second detection
* Thread CPU usage
* Process CPU usage
* Remove the special case for per process CPU time for Solaris, it's the same as the default.
* Don't include <sys/resource.h> on Fuchsia.
It doesn't support POSIX resource measurement and timing APIs.

* Add BENCHMARK_OS_FUCHSIA for Fuchsia
Change-Id: Ic536f9625e413270285fbfd08471dcb6753ddad1
This patch primarily changes the BENCHMARK_UNREACHABLE()
implementation under MSVC to use __assume(false) instead
of being a NORETURN function, which ironically caused
unreachable code warnings.
Second, since the NOTHROW function attempt generated the
warnings we meant to avoid, it has been replaced with a dummy
null statement.
* Refactor System information collection.
This patch refactors the system information collection,
and in particular information about the target CPU. The
motivation is to make it easier to access CPU information,
and easier to add new information as need be.
This patch additionally adds information about the cache
sizes of the CPU.
* Address review comments: Clean up integer types.
This commit cleans up the integer types used in ValueUnion to
follow the Google style guide.
Additionally it adds a BENCHMARK_UNREACHABLE macro to assist
in documenting/catching unreachable code paths.
* Rename ValueUnion accessors.
Define BENCHMARK_OS_NETBSD for NetBSD.
Add detection of cpuinfo_cycles_per_second and cpuinfo_num_cpus.
This code shared detection of these properties with FreeBSD.
Change ThreadCPUUsage to call ProcessCPUUsage if __rtems__ is defined.
RTEMS real time OS doesn't support CLOCK_THREAD_CPUTIME_ID. See
https://github.com/RTEMS/rtems/blob/master/cpukit/posix/src/clockgettime.c#L58-L59
Prior to this change, ThreadCPUUsage would fail when running on RTEMS with:
ERROR: clock_gettime(CLOCK_THREAD_CPUTIME_ID, ...) failed
* Make Benchmark a single header library (but not header-only)
This patch refactors benchmark into a single header, to allow
for slightly easier usage.
The initial reason for the header split was to keep C++ library
components from being included by benchmark_api.h, making that
part of the library STL agnostic. However this has since changed
and there seems to be little reason to separate the reporters from
the rest of the library.
* Fix internal_macros.h
* Remove more references to macros.h
* 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.
This patch cleans up our use of generic macros and also merges changes in the
build system.
It adds options -DBENCHMARK_ENABLE_TESTING and -DBENCHMARK_ENABLE_SHARED.
