--- Comment #1 from Hongtao.liu <crazylht at gmail dot com> ---
In the latest gcc version(GCC10_20190820), there's no difference in unroll
factor when applying this patch.
But still there's difference in Profitability threshold which changes from 5 to
4.
That means if loop count less than Profitability threshold, it won't trigger
vectorization.
So if loop count is 4, runtime performance would be different otherwise they
will be the same.
