[PATCH] D67392: [ARM][ParallelDSP] Change smlad insertion order

[Sjoerd Meijer via Phabricator via llvm-commits]

SjoerdMeijer added a comment.

I also hadn't though much about complexity, but indeed, function `RecordMemoryOps`, for example, is a bit of an expensive hobby.
Looking at it again, the bookkeeping looks essential, I don't see an easy way to reduce complexity. Delaying it may help a bit, but fundamentally that won't change much I think.
The usual way to deal with expensive hobbies is to introduce a threshold, and bail if it exceeds that.
