[PATCH] D99723: [ARM] Transforming memcpy to Tail predicated Loop

[Sjoerd Meijer via Phabricator via llvm-commits]

SjoerdMeijer added a comment.

I know you've worked on this for a while and investigated different strategies, but I think we also need to argue here why we would like to emit a memcpy loop instead of e.g. having optimised versions in the clib. In other words, is this the best we can do for all different alignments, sizes, etc.?
