Chris Lattner	c048bb3add	ADd two new 'add' methods ... llvm-svn: 5691	2003-03-03 23:28:05 +00:00
Chris Lattner	b5b0b7a934	Make the aliassettracker much more precise by actually tracking size ... information for various accesses. What a concept. llvm-svn: 5647	2003-02-26 22:11:00 +00:00
Chris Lattner	71b82bb494	Convert to work with new AliasAnalysis interface by conservatively assuming all pointers are arbitrarily large accesses ... llvm-svn: 5636	2003-02-26 19:28:57 +00:00
Chris Lattner	7606fb65c0	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. llvm-svn: 5619	2003-02-24 20:37:56 +00:00
Chris Lattner	647df647e1	First try at implementing the AliasSetTracker class. I'm sure it will need ... revision as I start to use it though. llvm-svn: 3954	2002-09-26 21:49:07 +00:00
