Hi, we encounter some weird problem on llvm generated codes, seems caused by current llvm tbaa annotations. The function `AddAliasInfo` will distinguish the index of scalar form and vectorized form. If we pass a scalar index but actually it is just the head of a ramp access, there is a possibility that overlapped accesses are infered as `NoAlias` by tbaa analysis unsafely. However, I am not sure how to reproduce the problem on common target like X86 cpu. Glad to see any suggestions:) cc @Lunderberg -- This is an automated message from the Apache Git Service.
