DA is not able to determine the presence of some dependencies, which is caused by the lack of overflow handling.
DA implements different dependence tests, and this issue is about fixing test "Weak-Crossing SIV".
Tests demonstrating the overflow issues and DA making incorrect decisions were committed in: https://github.com/llvm/llvm-project/pull/164246
Other dependence tests that need fixing up, for which we have separate issues, are: Weak-Zero SIV, Symbolic RDIV, and GCD MIV.
