[PATCH] D108087: [SimpleLoopUnswitch] Create SimpleLoopNestUnswitch pass

[toshiki maekawa via Phabricator via llvm-commits]

uint256_t added a comment.

For example, we may have an opportunity to perform loop-interchange (or some other transformations that require a perfect loop nest) after performing simple-loop-nest-unswitch.
We can perform simple-loop-unswitch after that, so there should be no problem for loop vectorization. 
How we arrange passes including simple-loop-nest-unswitch in a pass pipeline is still a problem though...
