[llvm-dev] LLVM flags for Vectorization

[Santanu Das via llvm-dev]

Hi,

I have been analyzing the LLVM vectorizer by running some benchmarks. For
vectorization, I have used the following flags:

-O3
-ffast-math
-mavx2

Am I missing any other flags which will improve vectorizer performance?

Thanks,
