Hi Sandhya,

Thanks for taking into account ARM SVE!

>From the description, you've mentioned that we just need to get
preferred species by API instead of the hardcoded concrete vector
shape. That's really good. But I just checked current VectorAPI code.
There are only 64, 128, 256 and 512 bit vector shapes. Regarding to
SVE's vector length agnostic feature, do you have a plan to extend
current vector shapes, e.g. introducing some kind of Agnostic shape?
