There are a lot of prefetch instructions and write-barriers in the available intrinsics:

I do not think one has full control over OOO execution on x86-64 processors. Also I do not believe one has control over the execution pipeline even in assembly, although I do not know exactly what you mean by that, so it could just be a misunderstanding.

My whole point is that this isn't C any longer, it is Assembly.

But assembly doesn't have instructions for "out-of-order execution, cache levels, execution pipelines, etc"

That is what Assembly data sheets provide.
