IIRC the Alpha did that as well but due to instruction pipelining it was more complicated in practice. I want to say it was used on some SCADA software but that's an ancient memory -- and it wasn't even everywhere in that software as I remember an integer overflow error in an alarm processing program that we had to hot-patch one night with live data, that was exciting.

Making myself nostalgic for the Alpha again ... I'll be over in the corner crying into my beer.
