Everything up to SSE4.2 as this is what is available on the current generation of CPUs. Thing that won't be supported includes MMX and 3DNow. Its also worth noting that SSE5 is (yet another) weird naming scheme in the superset scheme of things. AMD has announced it, but its not a superset of (all) of SSE4 but a competitor for (some) of it. Just to muddy the water a little more. I imagine when SSE5 is finalized and shipped we'll add support for it to Mono.Simd as well. -g ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
[Mono-dev] Mono's JIT and SSE instructions
Hi all, How does Mono deal with SSE-capable processors (or Altivec capable processors)? That is, does the JIT emit any SSE calls when there's a chance to use them, or are they totally unused in Mono?

On amd64 they are obviously used to implement the fp support. We don't use any altivec instruction as that is pretty much pointless. We don't auto vectorize from IL code, but we're developing an extension that allows people to take advantage of sse instructions with intrinsics (people watching the changes list can see it already). lupus -- - [EMAIL PROTECTED] debian/rules [EMAIL PROTECTED] Monkeys do it better ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
