The following code compiles on clang 11 x86 but not on arm:
```
template <class T>
struct A{
std::array<T,2> data_;
constexpr friend auto operator<=>(const A<T>& a, const A<T>& b)
{
return ( a.data_ <=> b.data_ );
}
};
```
Error message:
```
<source>:12:27: error: invalid operands to binary _expression_ ('const std::array<int, 2>' and 'const std::array<int, 2>')
return ( a.data_ <=> b.data_ );
```
