* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-107/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* Fix non-determinism in Reassociate caused by address coincidencesDaniel Sanders2019-03-221-0/+107
Summary: Between building the pair map and querying it there are a few places that erase and create Values. It's rare but the address of these newly created Values is occasionally the same as a just-erased Value that we already have in the pair map. These coincidences should be accounted for to avoid non-determinism. Thanks to Roman Tereshin for the test case.
