No, I quoted chapter and verse of the relevant Intel and AMD x86_64 docs
for you, complete with URLs and page numbers so it wouldn't take any
effort to verify what I was asserting.

I don't know what else I could have done (it was enough for bcrl, at
least), and you have come up any with suggestions as to what *would*
satisfy you, so I'm stuck.

And we don't have a portable way to do WC anyways, so there is
no portable way to use it.

So just put an ifdef in.

That's fine. Whatever satisfies reviewers :-)
