hi, I am writing blas functions in assembly to use in rust I have this project https://github.com/ozgurakkurt/aquila. When I run cargo bench sscal is as fast as openblas but when I run RUSTFLAGS="-C target-cpu=native" cargo bench It is 2x slower than openblas. Does anyone know why target-cpu=native is slowing my code?
