You study autovectorizers, then you enable autovectorization warning flags, and carefully read your compilers output.

If the compiler says autovectorization failed, you rewrite the code until the autovectorizer works.

hm, I have had limited success with such nudging - it's certainly not a programming model with a predictable outcome. And as soon as the compiler or its flags are updated, maybe the situation changes.
