--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Well, in this case I don't see any advantage of using collapsed loops, it won't
make the loop more readable and is much harder to vectorize, so why not to
write it that way?
Yes, there is certainly room for improvement to undo this kind of stuff.
