@fengyuentau This patch does not make many changes to SIMD optimization, so there should be no widespread performance degradation. After applying this patch, the compilation does not need to specify parameters such as -DCPU_BASELINE. I didn't see such a big performance gap in my local tests. I recommend that you can run a few more times.

This patch does not make many changes to SIMD optimization

So these changes are unintended, right?

No, these were intentionally modified by me. I just changed the implementation method to avoid mixing LSX instructions, and the number of instructions did not increase.
