--- Comment #13 from Richard Biener <rguenth at gcc dot gnu.org> ---
One option is to introduce a less invasive optimization option to avoid the
undesirable vectorization. For example -fno-vectorize-fp-inductions noting
this particular loop is a floating-point induction. Usually those tend not
to be performance critical.
More general -f[no-]vectorize-{in,re}ductions[={fp,int}] would be possible
as well.
