Since you and Bert Tenjy have now posted rival patch versions implementing
vector log, a key performance comparison would be against the version
posted by Bert Tenjy
<https://sourceware.org/ml/libc-alpha/2019-05/msg00054.html> - and in
general, you should compare and contrast the two versions of log to
justify why one might be better than another. It's also important in such
cases to be very clear about where exactly the patch you are posting fits
into exactly what other patch series.
