The testcase is large - what part requires this change? Given the
testcase was added for inconsistent warnings do they now become
inconsistent again as we enable vectorization at -O2?
That said, the testcase adjustments need some explaining - I suppose
you didn't just slap -fno-tree-vectorize to all of those changing
behavior?
Thanks,
Richard.
