I know there is works on AVX on llvm (and so clang) but I don't know what the status of this feature and I don't know if Xcode include a version that support it (if one exists).
Alternatively, you can isolate you AVX code in asm files that you compile using yasm (which support AVX for some times now).

I don't seen any public release notes anywhere so it's not easy to check, and I don't really need Xcode 4 yet unless it has AVX support.
