paulwalker-arm added a comment. As I see it there are a bunch of pragmas that all enable vectorisation, with each pragma providing a unit of information. One component of this information is the vectorisation factor hint provided by vectorize_width.
With the introduction of scalable vectors this hint is using the wrong datatype and thus needs to be updated to allow `vectorize_width(#num,[fixed|scalable])` and `vectorize_width([fixed|scalable])` along side the existing `vectorize_width(#num)` representation that effectively becomes an alias to `vectorize_width(#num, fixed)`. Doing this means all existing usages work as expected and there's now extra power to better guide the chosen vectorisation factor.
