[Bug target/70557] uint64_t zeroing on 32-bit hardware


https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70557

--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
In that case it is a backend enhancement request.  Backends have many ways how
to deal with this, starting from specialized patterns, or using the lower
subreg passes, using their own splitters etc. and many of the actively
maintained backends handle this right.
