What resources are there for Loop Vectorization (Manual and Automatic) for Visual Studio?

Question

I see some resources for gcc, but not for Visual Studio.

Anyone have a treasure trove of references, examples and tricks?

I don't think VC++ does loop vectorization. If you want it, you'll probably have to use Intel's compiler. Note that it will plugin to Visual Studio as a drop-in replacement.

Also see this question:

What compilers besides gcc can vectorize code?

UPDATE: The 2012 version reportedly does auto-vectorization now, see:

Vectorization is not supported by VC++. But, the SSE support is enabled via intrinsics. Please look this MSDN post.
