That's the old test which this patch has changed. Does it still fail
with the new patch?
My test results are indeed from a couple days ago. But, I looked at
your new modifications to this test, and still don't see anything like
the pattern it's looking for, or understand what output you expect to be
happening here. Is the whole test specific to vector ISAs, and not just
your recent changes to it? I've attached the .optimized dump I got on
nios2-elf.
