================
Comment at: llvm/lib/Transforms/Instrumentation/HWAddressSanitizer.cpp:674
+      Int8PtrTy,
+      ArrayRef(&HWAsanMemTransferArgTys[0], HWAsanMemTransferArgSize), false);
+  const size_t HWAsanMemsetArgSize = UseMatchAllCallback ? 4 : 3;
----------------
Can you make use of this constructor
```
template <size_t N>
    /*implicit*/ constexpr ArrayRef(const std::array<T, N> &Arr)
```

```
FunctionType *HWAsanMemTransferFnTy = FunctionType::get(
      Int8PtrTy,       ArrayRef(HWAsanMemTransferArgTys), false);
```
