--- Comment #4 from Anna <anna at azul.com> ---
Btw, the loop is no longer vectorized at O3. At O2, we see the same problem as
what occurs in 32396. The vector.recur.extract generated by
fixFirstOrderRecurrence assumes the last index (1) when trip-count=2 contains
the correct element. This is incorrect. 
The fix in 32396 fixes this as well.
