* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-16/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* Don't claim the udiv created in BypassSlowDivision is exact.Justin Lebar2016-10-281-0/+16
Summary: In BypassSlowDivision's short-dividend path, we would create e.g. udiv exact i32 %a, %b "exact" here means that we are asserting that %a is a multiple of %b. But we have no reason to believe this must be true -- this is just a bug, as far as I can tell.
