Carewolf,
Thanks for the feedback.
For me GCC does use SSE for me with and without '-ftree-vectorize' (when I tweak the C source code).
I couldn't get GCC to do vector math without changing the source file to calculate the number of loops for GCC. In a case as simple as this, the compiler should have been able to handle it.
I know Valhalla is complaining about this specific example (not sure why?), but I do frequently come across issues like this in much more complex code where GCC misses an equally trivial optimization.
