to match exceed combine's maximum.
Yes, I think that's already done - vectorizable_reduction checks for
such supported epilogue operation.
So I think the main issue right now is that vect_is_simple_reduction
needs to identify the beast as a single reduction.
I think it
ents you'd need to
match exceed combine's maximum.

Hi all,
Just looking for some feedback on the approach.
Currently the loop vectorizer can't vectorize the following typical loop
for getting max value and index from an array:
void test_vec(int *data, int n) {
int best_i, best = 0;
for (int i = 0; i < n; i++) {
