Chris Lattner	319d05bff4	ADd two new 'add' methods ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5691 91177308-0d34-0410-b5e6-96231b3b80d8	2003-03-03 23:28:05 +00:00
Chris Lattner	31a9d185bf	Make the aliassettracker much more precise by actually tracking size ... information for various accesses. What a concept. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5647 91177308-0d34-0410-b5e6-96231b3b80d8	2003-02-26 22:11:00 +00:00
Chris Lattner	2d0a4a4eb8	Convert to work with new AliasAnalysis interface by conservatively assuming all pointers are arbitrarily large accesses ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5636 91177308-0d34-0410-b5e6-96231b3b80d8	2003-02-26 19:28:57 +00:00
Chris Lattner	9971ac4a36	This is a substantial rewrite of the AliasSetTracker class which now uses ... 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	2003-02-24 20:37:56 +00:00
Chris Lattner	009cc3d2e8	First try at implementing the AliasSetTracker class. I'm sure it will need ... 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	2002-09-26 21:49:07 +00:00
