* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-68/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [PredicateInfo] Use custom mangling to support ssa_copy with unnamed types.Florian Hahn2018-07-241-4/+4
| | | | | | | | | | | | | | | | | | This is a workaround and it would be better to fix this generally, but doing it generally is quite tricky. See D48541 and PR38117. Doing it in PredicateInfo directly allows us to use the type address to differentiate different unnamed types, because neither the created declarations nor the ssa_copy calls should be visible after PredicateInfo got destroyed.
