Hi Serge,
this complains on this snippet from v8:
template <LOperand::Kind kOperandKind, int kNumCachedOperands>
class LSubKindOperand final : public LOperand {
public:
static LSubKindOperand* Create(int index, Zone* zone) {
if (index < kNumCachedOperands) return &cache[index];
return new(zone) LSubKindOperand(index);
}
private:
static LSubKindOperand* cache;
explicit LSubKindOperand(int index);
};
