   > Hi @zhanchangbao-sanechips , as you probably have in seen the SVE-handling 
code above your changes, we are using 
[xsimd](https://github.com/xtensor-stack/xsimd/) for instruction set detection. 
Can we ask you to do that for RVV too?
   > 
   > (you may need to contribute the required additions to xsimd if not already 
available)
   
   I referred to my previous PR: https://github.com/apache/orc/pull/2639. I 
will follow the same approach as the SVE handling and use xsimd for RVV 
instruction set detection.
