* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-7/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [GlobalOpt] Dead Eliminate declarationsMehdi Amini2016-09-151-0/+7
GlobalOpt is already dead-code-eliminating global definitions. With this change it also takes care of declarations. Hopefully this should make it now a strict superset of GlobalDCE. This is important for LTO/ThinLTO as we don't want the linker to see "undefined reference" when it processes the input files: it could prevent proper internalization (or even load an extra file from a static archive, changing the behavior of the program!). llvm-svn: 281653
