You're leaving out Atmel AVRs, and Crays.

Regrettably, that's the option limit on polls, apparently. Though I suppose I could have gone with a continuation as the second question.. Atmel especially. And that Hitachi widget in the Dreamcast.. I had Alpha in there too, but as I recall, you needed to be fairly masochistic to try assembly development on an Alpha.

Can you lay claim to Cray assembly, then? How is/was it?

Okay, so I still do have Alpha. The rest of the sentence stands. ^_^;

I know people who have. I've only ever run compiled code on any Crays, and this a long while ago. I think the Y-MP had a 42 bit fast int data type... The main thing about those is that they're more or less one or two digit serial number machines, so sometimes it really IS a compiler bug. They're also vector machines in a way that I don't think SSE type things really are. The granularity of the vector operations for max throughput isn't cache line sized; it's bigger than that, and there are special vector registers, and funny pick'm choose'm registers, in imperfect recollection...
