The ARM64 backend could convert Smi to Operand by assigning tagged Smi to
immediate filed in Operand class, as below code snippet. Then the immediate
field is tagged Smi value, would it cause problem when encoding this
operand?
// src\arm64\assember-arm64-inl.h
template<>
struct ImmediateInitializer<Smi*> {
static const bool kIsIntType = false;
static inline RelocInfo::Mode rmode_for(Smi* t) { return RelocInfo::NONE;
}
static inline int64_t immediate_for(Smi* t) {;
return reinterpret_cast<int64_t>(t);
}
};
