// This header file intentionally does not have include guard because
// the purpose of this header file is embedding boilerplate code and
// you may want to use this header file multiple times from a file.

// This header file provides a generic way to save compiler's warning
// settings so that you can restore the settings later by
// "pop_warning_settings.h" when you want to disable some unavoidable
// warnings temporarily.
// Currently Visual C++, GCC 4.6 and later, and Clang are supported.
// On GCC 4.5 and prior, this header does nothing.
//
// Usage example:
//   #include "base/push_warning_settings.h"
//   #if defined(__GNUC__) && (__GNUC__ * 100 + __GNUC_MINOR__ >= 405)
//   #pragma GCC diagnostic ignored "-Wconversion-null"
//   #endif  // GCC 4.5 and greater
//   EXPECT_EQ(false, false);
//   #include "base/pop_warning_settings.h"

#if defined(_MSC_VER)
  // Visual C++
  #pragma warning(push)
#elif defined(__GNUC__) && (__GNUC__ * 100 + __GNUC_MINOR__ >= 406)
  // G++ 4.6 and greater
  #pragma GCC diagnostic push
#elif defined(__clang__)
  // Clang
  #pragma clang diagnostic push
#endif
