--- Comment #1 from ktkachov at gcc dot gnu.org ---
I think this is a problem with the <shift>di3_neon pattern in neon.md and in
particular the neon_for_64bits/avoid_neon_for_64bits stuff in the arch
attribute.
I think the last two alternatives that generate the NEON version should have
avoid_neon_for_64bits in their arch attribute rather than neon_for_64bits
