Compiling for the AMD Athlon 64X2

I have been generating code only for Intel chips but now need to provide optimized code that runs on platforms with the AMD Athlon. Can someone provide the compiler options I need? Is there a document around that provides background information about this? The current version of "Optimizing Applications" doesn't directly adddress this.

/QxW performs SSE2 optimizations suitable for both AMD64 and Intel CPUs.
In ifort 10, /QxO adds SSE3 which is suitable for AMD64 and Intel CPUs which support SSE3. This is most likely to be useful when there is vectorizable complex arithmetic.
