* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-18/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* Use a WeakVH for UnknownInstructions in AliasSetTrackerSanjoy Das2017-03-111-0/+18
Summary: This change solves the same problem as D30726, except that this only throws out the bathwater. AST was not correctly tracking and deleting UnknownInstructions via handles. The existing code only tracks "pointers" in its `ASTCallbackVH`, so an UnknownInstruction (that isn't also def'ing a pointer used by another memory instruction) never gets a `ASTCallbackVH`. There are two other ways to solve this problem: - Use the `PointerRec` scheme for both known and unknown instructions. - Use a `CallbackVH` that erases the offending Instruction from the UnknownInstruction list. Both of the above changes seemed to be significantly (and unnecessarily IMO) more complex than this.
