[edit] VIS support in SPARC64?

Poking around a little on the net, it seems like VIS is supported in at least SPARC64 VI (but maybe not earlier revs?). Can a subject expert weigh in here?--NapoliRoma 21:05, 3 December 2007 (UTC)

Found mention of VIS 1 in SPARC64 V documentation.--NapoliRoma 22:16, 3 December 2007 (UTC)

As far as I know, VIS is supported on relatively new SPARC64 processors. But some instructions are not directly supported by hardware (microcode or trap? not sure), so performance of VIS on SPARC64 might not be as good as that on UltraSPARC. Houyi 10:57, 4 December 2007 (UTC)
