Eric Fiselier 3b2d0abd2b Use correct integer type for complexity. MSVC warns otherwise 2016-07-22 17:48:37 -06:00
Eric Fiselier 950c8b7440 Fix suprious failures in complexity_test.cc 2016-07-22 17:31:05 -06:00
Eric Fiselier 440df36e7a Improve failure mode in complexity_test.cc 2016-07-22 16:18:34 -06:00
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")
