[PATCH] D85454: [ARM] Allow vecreduce_add in tail predicated loops

[Sjoerd Meijer via Phabricator via llvm-commits]

SjoerdMeijer added a comment.

Just a remark on this:

> I was temped to try to change the MVETailPredication pass to a simpler "if loop has a activelanemask, convert it to a vctp" pass.

After the rewrite of this pass to use activelanemask, that's essentially all there's left here, so I wouldn't see the benefit of that (unless I miss something). But anyway, what Sam said, nice codegen changes.
