Is it valid to dereference a pointer that have undef bits in its offset?
...will store zero to one of the array's elements. The reason is that I want to improve no-undef analysis by suggesting that a pointer that is passed to load/store is well-defined, by making it raise UB when a pointer with undef bits is given. A suggested patch is here: https://reviews.llvm.org/D87994 I wonder whether there is a case using this to do something that I'm not aware.
