* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-53/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [LoopUnroll] Fix the way we update DT after complete unrolling.Michael Zolotukhin2016-04-061-0/+53
Updating dominators for exit-blocks of the unrolled loops is not enough, as shown in PR27157. The proper way is to update dominators for all dominance-children of original loop blocks. llvm-svn: 265605
