Hi,all I have a Value* type named indexValue, and the type is i32. I think "indexValue" must hold a number which type is int. Now I want to use the exact number which pointed by indexValue , so I do like this: ConstantInt* CI = llvm::cast<llvm::ConstantInt>(indexValue); //This is wrong, so is dyn_cast. uint64_t index = index...

Correct, but it might not be a constant. > ConstantInt* CI = llvm::cast<llvm::ConstantInt>(indexValue); //This is wrong, so is dyn_cast. > uint64_t index = indexValue->getZExtValue();...

...will appreciate if you could give me some suggestion on this.
