Prerequisites

• MSVC 2019+ It's better to use clang-cl because of this bug
• Clang 7.0+
• GCC 8.3+
• Gtest
• CMake
• Ninja build (optional)

For Windows:

Use vcpkg or conan package managers to install Gtest library

For Linux (depends on your distro):

Ubuntu

sudo apt-get install libgtest-dev

Fedora

sudo dnf install gtest-devel

Building

Don't forget to specify toolchain file if you use package managers (-DCMAKE_TOOLCHAIN_FILE=...)

cmake -G "Ninja" ..
ninja

Diff

For each compilation you will get different assembly code

uint64_t diff_me(uint64_t x) {
  using u64 = uint64_t;
  CNNInt<u64> r(std::chrono::system_clock::now().time_since_epoch().count());
  CNNInt<u64> test(x);
  test++;
  test--;
  test|=r;
  test^=r;
  test&=r;
  test^=r;
  test = ~test;
  return test.value();
}

For example:
