--- Comment #2 from Trass3r <trass3r at gmail.com> ---
Not exactly. Let's forget about the int return type:
https://godbolt.org/g/dm8nvd

 control flow cannot be substituted for a select
 value that could not be identified as reduction is used outside the loop
 cannot identify array bounds

I disabled loop unroll to actually see some vectorizer analysis results.
Is it intentional that the unroller "overrides" the loop vectorizer?
Does the SLP vectorizer kick in after that? I couldn't find any analysis option
for it.
