Member Data Documentation

Use* llvm::User::OperandList [protected]

OperandList - This is a pointer to the array of Users for this operand. For nodes of fixed arity (e.g. a binary operator) this array will live prefixed to the derived class. For nodes of resizable variable arity (e.g. PHINodes, SwitchInst etc.), this memory will be dynamically allocated and should be destroyed by the classes' virtual dtor.
