[PATCH] D154157: [LV] Cost model for out-of-loop reductions

[Anna Thomas via Phabricator via llvm-commits]

anna added a comment.

Gentle ping @fhahn. Anything I could do to move this forward? I have kept the option as off by default, since I would need to help to test this on supported targets upstream. It helps our use-case where loops are not vectorized when out-of-loop reductions are present in small trip count loops. 
There maybe some fallouts where correction in reductions cost modelling will be required.
