[LLVMdev] PROPOSAL: struct-access-path aware TBAA (new version)
...s coming up. If we see bugs coming up with struct-path aware TBAA, we can do less aggressive TBAA or apply similar tricks as GCC. Scalar TBAA will say NoAlias for the placement new example under test/Analysis/TypeBasedAliasAnalysis/placement-tbaa.ll. If we optimize placement-tbaa.ll with -O1 -gvn, BaiscAA will start saying MustAlias. This may cause problem.
