--- Comment #15 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I've gathered some statistics, the vsx_reduc_<VEC_reduc_name>_v2df
define_insn_and_split is never used during powerpc64-linux bootstrap and
-m32/-m64 testing and during powerpc64le-linux bootstrap and testing is only
triggered on the miscompiled reduction-3.f90.  That doesn't mean it can't be
useful for big endian, I just don't know how to trigger it to verify if it is
beneficial or not.
