   I see, looking into the case. Both this example and #5130 seems to appear when the iteration is dependent on an outer loop. And we will need to find a detector to insert the condition properly when generating the loops. 
   
   The current compute bound insertion assumes the loop bounds to not being iterator dependent. A contribution would be more than welcomed.
   
   It might also be useful to think about what can be done and (cannot be done) in iterator dependent loops. As the original assumption of compute means the axis should be independent from each other for certain scheduling correctness to hold. In this case, a dependent reduction bound would certainly bring different implications, and possible different analysis for the scheduling to hold
