                    'TempRegister<(TempRegisterType)'\x00'>' to
                    'RegisterID'
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified

Here is the error I encountered while compiling on sipeed licheepi4a (a riscv64gc board)

    m_assembler.sllwInsn(dest, temp, shiftAmount);

    move (imm, temp);
```

I think we should call TempRegister.data() here

```txt
template<TempRegisterType... RegisterTypes>
    struct TempRegister {
        RegisterID data()
        {
            static_assert(((RegisterTypes == Data) || ...));
            return dataTempRegister;
        }
```
