Oh, I see. So, you meant something like this?
void foo(std::vector<float * __attribute__((nontemporal))> av, float * b, int
N) {
for (auto a: av) // << `a` doesn't have nontemporal attribute here
for (int i = 0; i < N; i++)
a[i] = b[i]+1;
}
One can easily work around it by using an explicit type here (`float *
__attribute__((nontemporal))` instead of `auto`), but I agree that disappeared
attribute might be a surprise for the user. Do you think it would be a frequent
case?
BTW, there are other type attributes, which also suffer from the same issue,
e.g. `vector_size`. What was the rationale of making them type attributes?
