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


1:

```txt
/home/debian/repo/WiebKit/Source/JavasoriptCore/assenbler/MacroAssenberRISCV64.h:662:36: error: no viable conversion from 'TempRegister<(TempRegisterType)'\x00'>' to 'RegisterID' (aka 'JSC::RISCVé64Registers::RegisterID')
    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;
        }
```
