-// Unfortunately there's no standard way of preventing a function from being
-// inlined, so we define a macro for it.
-//
-// You should use it like this:
-// NOINLINE void function() {...}
-#if defined(__GNUC__)
-// This also works and will be defined for any compiler implementing GCC
-// extensions, such as Clang and ICC.
-#define NOINLINE __attribute__((noinline))
-#elif defined(_MSC_VER)
-#define NOINLINE __declspec(noinline)
-#else
-// We give out a warning because it impacts the correctness of one bignum test.
-#warning You should define NOINLINE for your compiler.
-#define NOINLINE
-#endif
-
-// For the following test case, it is useful to use additional tools.
-//
-// The simplest one to use is the compiler flag -ftrapv, which detects integer
-// overflows and similar errors. However, due to optimizations and compilers
-// taking advantage of undefined behavior sometimes it may not actually detect
-// anything.
-//
-// You can also use compiler-based stack protection to possibly detect possible
-// stack buffer overruns.
-//
-// For more accurate diagnostics, you can use an undefined arithmetic operation
-// detector such as the clang's undefined behaviour checker.
-// See also: http://clang.llvm.org/docs/UsersManual.html#controlling-code-generation
-//
-// It might also be useful to use Google's AddressSanitizer to detect
-// stack buffer overruns, which valgrind can't currently detect.
-
-// Let's force this code not to be inlined, in order to actually
-// test a generic version of the function. This increases the chance
-// that -ftrapv will detect overflows.

-// value to 0, then the second one with a non-inlined function.
