* | [LoopRotate] Rotate loops with loop exiting latches | David Green | 2018-04-01 | 1 | -0/+234 |
If a loop has a loop exiting latch, it can be profitable to rotate the loop if it leads to the simplification of a phi node. Perform rotation in these cases even if loop rotate itself didnt simplify the loop to get there. Differential Revision: https://reviews.llvm.org/D44199 llvm-svn: 328933 |
