Hi,

You don't need to care about address spaces to check for an int32*:

if (T->isPointerTy()) {
  const Type* intT = cast<PointerType>(T)->getElementType();
  if (intT->isIntegerTy() && intT->getPrimitiveSizeInBits() == 32)
    cout << "Yeah!" << endl;
}

Also, to create a pointer type, if you don't care about address space
at all, use the unqualified version:

const Type* ptrT = PointerType::getUnqual(intT);

cheers,
