2006-06-27Handle alias sets that have been unified, and thus can have other referencesChris Lattner
to them. This fixes a regression in my previous checkin. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28951 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-27Don't implement AliasSetTracker::remove in terms of deleteValue. deleteValueChris Lattner
causes the pointer to be removed from the underlying alias analysis implementation as well. This impl of remove is also significantly faster than the old one. This fixes: Regression/Transforms/DeadStoreElimination/2006-06-27-AST-Remove.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28950 91177308-0d34-0410-b5e6-96231b3b80d8

2004-03-15Ok, the assertion was bogus. Calls that do not read/write memory should notChris Lattner

2003-12-18Add a new AliassetTracker::remove method. Because we need to be able to removeChris Lattner
a pointer from an AliasSet, maintain the pointer values on a doubly linked list instead of a singly linked list, to permit efficient removal from the middle of the list. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10506 91177308-0d34-0410-b5e6-96231b3b80d8

2003-02-26Make the aliassettracker much more precise by actually tracking sizeChris Lattner
information for various accesses. What a concept. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5647 91177308-0d34-0410-b5e6-96231b3b80d8

2003-02-24This is a substantial rewrite of the AliasSetTracker class which now usesChris Lattner
a union-find based algorithm, is significantly faster, and is more general. It will also scale to handle call instructions correctly, which is a nice added bonus. This includes a new pass -print-alias-sets which can be used to show how alias sets are formed for a particular analysis. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5619 91177308-0d34-0410-b5e6-96231b3b80d8
2002-09-26First try at implementing the AliasSetTracker class. I'm sure it will needChris Lattner
revision as I start to use it though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3954 91177308-0d34-0410-b5e6-96231b3b80d8
