--- Comment #10 from amker at gcc dot gnu.org ---
Patches @https://gcc.gnu.org/ml/gcc-patches/2016-08/msg00058.html and
https://gcc.gnu.org/ml/gcc-patches/2016-08/msg00059.html implements
vcond_mask/vec_cmp/vcond stuff on AArch64 and fix the target dependent problem.
 Number of instructions inside the loop is 8 with them.

The target-independent problem remains and needs different fix.
