* [Tests] Autogen a bunch of Reassociate tests for ease of updatePhilip Reames2019-08-011-14/+29
| | | | llvm-svn: 367634
* Revert "Temporarily Revert "Add basic loop fusion pass.""Eric Christopher2019-04-171-0/+45
| | | | | | | | The reversion apparently deleted the test/Transforms directory. Will be re-reverting again. llvm-svn: 358552
* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-45/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [Reassociate] Don't propogate flags when creating negationsDavid Majnemer2015-06-241-0/+11
| | | | | | | | | Reassociate mutated existing instructions in order to form negations which would create additional reassociate opportunities. This fixes PR23926. llvm-svn: 240593
* [Reassociate] Canonicalize negative constants out of expressions.Chad Rosier2014-11-111-3/+3
| | | | | | | | This is a reapplication of r221171, but we only perform the transformation on expressions which include a multiplication. We do not transform rem/div operations as this doesn't appear to be safe in all cases. llvm-svn: 221721
* [Reassociate] Better preserve NSW/NUW flags.Chad Rosier2014-11-071-0/+34
