* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-35/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [LV] Don't mark multi-use branch conditions uniformMatthew Simpson2016-10-071-0/+35
Previously, we marked the branch conditions of latch blocks uniform after vectorization if they were instructions contained in the loop. However, if a condition instruction has users other than the branch, it may not remain uniform. This patch ensures the conditions we mark uniform are only used by the branch. This should fix PR30627.
