Eli Friedman 0e382192c1 PR9634: Don't unconditionally tell the AliasSetTracker that the PreheaderLoad ... is equivalent to any other relevant value; it isn't true in general. If it is equivalent, the LoopPromoter will tell the AST the equivalence. Also, delete the PreheaderLoad if it is unused. Chris, since you were the last one to make major changes here, can you check that this is sane? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129049 91177308-0d34-0410-b5e6-96231b3b80d8		2011-04-07 01:35:06 +00:00
