Actually, I believe Jonathan is correct. I misread the CWG. The "range" of an
enum class has nothing to do with how many enumerators it has.

With the following function signature (that is within a struct):
void compute(int *__restrict x) { /* ... */ }
Adding an additional __restrict for the this pointer as

The following code will get much better assembly if it is not in main():
for (int i = 0; i < 1024; ++i)
result[i] = first[i] * sec
