That's a neat optimisation, but it gets its gains by pushing some of the required processing out of the benchmark.

What I mean by that is that the sets of 32 numbers are manipulated in pairs (of sets).

So, using uicb() I would have to expand one set to the buffer; copy them somewhere else; then expand the second set; before I could then do the manipulations. Ie, the copying would still need to be done, but it is no longer being measured.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
