Extended Description
/// ConcreteOperator - A helper template for defining operators for individual
/// opcodes.
template<typename SuperClass, unsigned Opc>
class ConcreteOperator : public SuperClass {
~ConcreteOperator(); // DO NOT IMPLEMENT
public:
static inline bool classof(const ConcreteOperator<SuperClass, Opc> *) {
return true;
}
static inline bool classof(const Instruction *I) {
return I->getOpcode() == Opc;
}
static inline bool classof(const ConstantExpr *CE) {
return CE->getOpcode() == Opc;
}
static inline bool classof(const Value *V) {
return (isa(V) && classof(cast(V))) ||
(isa(V) && classof(cast(V)));
}
};
When including the Operator.h file and compiling with g++ 4.6 and C++0x is enabled (--std=c++0x) the not implemented destructor causes a compiler error. Commenting out the line fixes the issue, but I'm not sure if this is the right fix. Anyway it's not clear to me what's the rationale behind such constructor.
