I will do a bit more investigation and report back.
I wonder if instead of "visually testing" shouldn't it be verified by some
more exact tests? Could any of these be useful:
https://gcc.gnu.org/ml/gcc-patches/2002-11/msg01391.html
https://gcc.gnu.org/git/?p=gcc.git;a=tree;f=gcc/testsuite/gcc.dg/vmx;h=4765c35dabb4e3891c98084af077c2549fb45dfc;hb=HEAD
https://github.com/llvm-mirror/test-suite/tree/master/SingleSource/UnitTests/Vector/Altivec
or there could be other similar ones around that already have test cases
for these instructions that could provide some more confidence in the
correctness of the implementation.
