If avoiding the crash is the main concern, I think it is better to insert a TODO, as you pointed out and as mentioned in my comment, the situation is more complex and you need to have the acc.loop returning a "branching code" and insert the jump after the loop to properly cover the different cases.

Dropping the acc.loop all together is also a bit problematic because it is used to carry the data directive that it may have (even if sequential).
