* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-31/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [LICM] Preserve DT and LoopInfo specificallyJun Bum Lim2018-05-241-0/+31
Summary: In LICM, CFG could be changed in splitPredecessorsOfLoopExit(), which update only DT and LoopInfo. Therefore, we should preserve only DT and LoopInfo specifically, instead of all analyses that depend on the CFG (setPreservesCFG()). This change should fix PR37323.
