Hi Bob
Thank you very much for your information

Can you  provide me some documents that explain why automatic 
vectorization is poor? 

I want to know which compiler option is better: using mfpu=neon or not? So 
I am looking for some C source code (no assembly inside) that can be 
compiled to NEON instructions.
However, I can 't find.

Any information would be helpful.
