BasicAA: GEPs of NoAlias'ing base ptr with equivalent indices are NoAlias If we can show that the base pointers of two GEPs don't alias each other using precise analysis and the indices and base offset are equal then the two GEPs also don't alias each other. This is primarily needed for the follow up patch that analyses NoAlias'ing PHI nodes. Part 1/2 of fix for PR13564. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163317 91177308-0d34-0410-b5e6-96231b3b80d8
