-// Creates a `std::unique_ptr<>`, while avoiding issues creating temporaries
-// during the construction process. `absl::make_unique<>` also avoids redundant
-// type declarations, by avoiding the need to explicitly use the `new` operator.
-//
-// This implementation of `absl::make_unique<>` is designed for C++11 code and
-// will be replaced in C++14 by the equivalent `std::make_unique<>` abstraction.
-// `absl::make_unique<>` is designed to be 100% compatible with
-// `std::make_unique<>` so that the eventual migration will involve a simple
-// rename operation.
-//
-// For more background on why `std::unique_ptr<T>(new T(a,b))` is problematic,
-// see Herb Sutter's explanation on
-// (Exception-Safe Function Calls)[https://herbsutter.com/gotw/_102/].
-// (In general, reviewers should treat `new T(a,b)` with scrutiny.)
-//
-// Example usage:
-//
-//    auto p = make_unique<X>(args...);  // 'p'  is a std::unique_ptr<X>
-//    auto pa = make_unique<X[]>(5);     // 'pa' is a std::unique_ptr<X[]>
-//
-// Three overloads of `absl::make_unique` are required:
-//
-//   - For non-array T:
-//
-//       Allocates a T with `new T(std::forward<Args> args...)`,
-//       forwarding all `args` to T's constructor.
-//       Returns a `std::unique_ptr<T>` owning that object.
-//
-//   - For an array of unknown bounds T[]:
-//
-//       `absl::make_unique<>` will allocate an array T of type U[] with
-//       `new U[n]()` and return a `std::unique_ptr<U[]>` owning that array.
-//
-//       Note that 'U[n]()' is different from 'U[n]', and elements will be
-//       value-initialized. Note as well that `std::unique_ptr` will perform its
-//       own destruction of the array elements upon leaving scope, even though
-//       the array [] does not have a default destructor.
-//
-//       NOTE: an array of unknown bounds T[] may still be (and often will be)
-//       initialized to have a size, and will still use this overload. E.g:
-//
-//         auto my_array = absl::make_unique<int[]>(10);
-//
-//   - For an array of known bounds T[N]:
-//
-//       `absl::make_unique<>` is deleted (like with `std::make_unique<>`) as
-//       this overload is not useful.
-//
-//       NOTE: an array of known bounds T[N] is not considered a useful
-//       construction, and may cause undefined behavior in templates. E.g:
-//
-//         auto my_array = absl::make_unique<int[10]>();
-//
-//       In those cases, of course, you can still use the overload above and
-//       simply initialize it to its desired size:
-//
-//         auto my_array = absl::make_unique<int[]>(10);
-
-// `absl::make_unique` overload for non-array types.
-template <typename T, typename... Args>
-typename memory_internal::MakeUniqueResult<T>::scalar make_unique(
-    Args&&... args) {
-  return std::unique_ptr<T>(new T(std::forward<Args>(args)...));
-}
-
-// `absl::make_unique` overload for an array T[] of unknown bounds.
-// The array allocation needs to use the `new T[size]` form and cannot take
-// element constructor arguments. The `std::unique_ptr` will manage destructing
-// these array elements.
-template <typename T>
-typename memory_internal::MakeUniqueResult<T>::array make_unique(size_t n) {
-  return std::unique_ptr<T>(new typename onnxruntime::remove_extent_t<T>[n]());
-}
-
-// `absl::make_unique` overload for an array T[N] of known bounds.
-// This construction will be rejected.
