I am applying this pass specifically to omp::simdOp, not to all operations within the function. All the nontemporal examples that I referred so far have omp.simd nested inside a function, so I run the pass at the function level, look for omp::simdOp  and only add the attribute when such an operation(omp::simdop) is present. 

Could you please share an example that explains the scenario "omp.simd" op is not nested inside function? 
That would help me to understand better.
