* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-33/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* SLPVectorizer: Fix stale for Value pointer arrayArnold Schwaighofer2013-11-191-0/+33
We are slicing an array of Value pointers and process those slices in a loop. The problem is that we might invalidate a later slice by vectorizing a former slice. Use a WeakVH to track the pointer. If the pointer is deleted or RAUW'ed we can tell. The test case will only fail when running with libgmalloc. radar://15498655 llvm-svn: 195162
