[PATCH] D88962: [SVE] Add support for scalable vectors with vectorize.scalable.enable loop attribute

Hi @SjoerdMeijer, what I have in the clang pragma patch at the moment is a warning emitted when the target doesn't support scalable vectors, and falling back on fixed width. However, this is something for discussion as I believe there are others who think that the fronted should simply accept the scalable hint regardless and let the vectoriser make that decision based upon cost analysis.
