Eric Fiselier 8228b3e8a7 Make Appveyor show test output on failure 2016-08-07 20:09:52 -06:00
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.

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.

Eric Fiselier 1b57a2ad05 Add myself to AUTHORS. 
This is secretly just a test commit to get appveyor to run again.

Eric Fiselier f30028b2a8 Attempt to fix VC 2013 build. 
VC 2013 injects valid when  assigning an initializer list to std::set.
This attempts to work around this issue by using std::set's constructors
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 b7f8e355ee update travis, squash history (#265) 2016-08-02 14:47:29 -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.

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.

Eric Fiselier c5f454957d Workaround missing std::this_thread::sleep_for function in tests. 
GCC 4.7 doesn't provide std::this_thread::sleep_for on my system.
This patch changes the tests to use a different method for wasting
cycles.

Sven ebd37b191c set cpuinfo_num_cpus on Windows (#254) 2016-07-13 13:00:32 -07:00
Elliott Hughes b805b7c6e0 Add missing `volatile`s 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.

Eric Fiselier 7e40ff9e35 Provide a better implementation of DoNotOptimize(...). 
This implementation is less likely to ICE compilers, and is more correct.
It also acts as a memory barrier which will help prevent writes to global memory
from being optimized away.

Steve Downey 2149577f89 Add export linker flags policy to cmake (#251) 
Add policy CMP0056, which honors the link flags in try_compile and
try_run. This allows for building against non-system libc++ by providing
the correct -L and rpath options in a containing project.

For example:

    set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -L ${LLVM_ROOT}/lib -l c++ -l c++abi")
    set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -Wl,-rpath,${LLVM_ROOT}/lib")
