Daniel Berlin 7a5c0e599c Update BasicAliasAnalysis to understand that nothing aliases with undef values. ... It got this in some cases (if one of them was an identified object), but not in all cases. This caused stores to undef to block load-forwarding in some cases, etc. Added test to Transforms/GVN to verify optimization occurs as expected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236511 91177308-0d34-0410-b5e6-96231b3b80d8		2015-05-05 18:10:49 +00:00
