+1  Q: 

Resources for (Manual and Automatic) Loop Vectorization

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

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

+2  A: 

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:

A: 

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