* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-42/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [NFC] Remove overconfident assert from IRCEMax Kazantsev2018-01-241-0/+42
This patch removes assert that SCEV is able to prove that a value is non-negative. In fact, SCEV can sometimes be unable to do this because its cache does not update properly. This assert will be returned once this problem is resolved. llvm-svn: 323309
