It seems that we don't converge for this one. So it would probably
better if you do a complete patch for this that satisfies you
personally.
I need the complete functionality to build on my 128 bit patches and
to have a complete C23 system for my tests. So I will keep my variant
in my series for the moment, and rebase on top of yours once that is
ready and tested.
(Same for `memset` by the way or any other patch that you guys think
can be implemented better than I have foreseen.)
Thanks
