[llvm-dev] auto simd

[林政宗 via llvm-dev]

Hi, there
I am doing optimization for an new backend. And I have read the auto-vectorization guide,https://llvm.org/docs/Vectorizers.html.
The hardware support vector operation. I wonder how can I get the loop vectorizer tuned for my backend. 
Is there any documents or suggestions? Thanks!




Best regards,
Jerry
