David Majnemer f47d325eec AliasSetTracker: UnknownInsts should contribute to the refcount ... AliasSetTracker::addUnknown may create an AliasSet devoid of pointers just to contain an instruction if no suitable AliasSet already exists. It will then AliasSet::addUnknownInst and we will be done. However, it's possible for addUnknown to choose an existing AliasSet to addUnknownInst. If this were to occur, we are in a bit of a pickle: removing pointers from the AliasSet can cause the entire AliasSet to become destroyed, taking our unknown instructions out with them. Instead, keep track whether or not our AliasSet has any unknown instructions. This fixes PR21582. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@222338 91177308-0d34-0410-b5e6-96231b3b80d8		2014-11-19 09:41:05 +00:00
