- return Builder.CreateBitCast(Addr, ConvertType(E->getType()));
+ return Builder.CreatePointerBitCastOrAddrSpaceCast(
+ Addr, ConvertType(E->getType()));

It seems for consistency then we would have to assert for both different ASes in non-`addrspacecast` case and equivalent ASes in the other case.
As condition becomes complicated then, I could as well split into either creating `bitcast` or `addrspacecast` explicitly at a cost of one simple check in the return statement but that would be in release build too.
