When was MOVNTQ introduced?

Is it one of the original MMX instructions, or was it added with the SSE instruction set?
I assume it was added with the SSE instruction set, since the intel manuals say you get a #UD if the CPUID.SSE flag is not set... but later it mentions #UD if CPUID.SSE2 is not set :s

Does anybody have a decent and correct reference that shows when the various instructions were introduced?

on this page, movntq is listed as a sse instruction introduced in the pentium 3.

Thanks - I guess I should have a look at sandpile, too - been too long since I visited those sites :)

Intel's manual says that MOVNTQ requires SSE in protected mode, and SSE2 in real-address mode.

Yep, as I wrote before... but this doesn't make any sense, does it? Sounds more like a typo to me :)

well dunno. maybe Pentium 3 doesn't have this instruction in real-address. it's possible (low chance but still possible) that intel wanted to cut the costs and implemented in only for protected mode. the instruciuon itself is "memory instruction" -- it plays with the cache, etc, (and maybe it's harder to do it in real-address? after all we're not intlel architects so we don't know if it is) so it seems like very strange coincidence...

...or just a typo :P

Considering that intel has been known for typos (ask any disassembler author), I would bet on the typo :)
