If not, then you're right and I will go forth and fix the data on the tables. Also, I noticed something else, those opcodes, while on 2007 binutils, are not in the current version of binutils-and I guess that there are no respective intrinsics in gcc for that matter. Anyone by any chance knows why? If VMX128 is a completely dead and obsolete SIMD unit then perhaps I should not include it, it has been very hard finding documentation on it as it, the only things I could find were these: http://download.microsoft.com/download/2/2/0/2208E622-4365-4C00-A6E7-9C3A0190EAAA/Case_Studies_in_VMX128_Optimization_US.zip and http://download.microsoft.com/download/e/3/7/e3791b88-c41d-4a49-a24c-e4ccfbca4843/Using%20VMX%20and%20SSE%20Instructions%20for%20Performance.zip However, these include some -probably informative- docs on xds.xbox.com, which does not exist anymore. So the links you mentioned and the above are the only info I could find on vmx128. Anyway, thanks a lot for your time. Konstantinos
