Again, the fact they appear doesn't mean they are good or required. 

Take your example:
```mlir
      %a_ptr = tt.addptr %group_a_ptrs, %g : !tt.ptr<i64>, i32
      %a_ptr_6 = tt.load %a_ptr : !tt.ptr<i64>
      %a_ptr_7 = tt.int_to_ptr %a_ptr_6 : i64 -> !tt.ptr<f16>
```

It could be transformed into something like:

```mlir
      %a_ptr = tt.addptr %group_a_ptrs, %g : !tt.ptr<!tt.ptr<f16>>, i32
      %a_ptr_6 = tt.load %a_ptr : !tt.ptr<!tt.ptr<f16>>
```
