+               IRB.CreatePointerCast(Addr, IRB.getInt8PtrTy()), Origin});
+      CB->addAttribute(AttributeList::FirstArgIndex, Attribute::ZExt);
+      CB->addAttribute(AttributeList::FirstArgIndex + 2, Attribute::ZExt);
----------------
I suggest `CB->addParamAttr` as a shorter spelling for the same stuff. I noticed DFSan does it that way.
