bors 00095b3da4 Auto merge of #132527 - DianQK:gvn-stmt-iter, r=oli-obk ... gvn: Invalid dereferences for all non-local mutations Fixes #132353. This PR removes the computation value by traversing SSA locals through `for_each_assignment_mut`. Because the `for_each_assignment_mut` traversal skips statements which have side effects, such as dereference assignments, the computation may be unsound. Instead of `for_each_assignment_mut`, we compute values by traversing in reverse postorder. Because we compute and use the symbolic representation of values on the fly, I invalidate all old values when encountering a dereference assignment. The current approach does not prevent the optimization of a clone to a copy. In the future, we may add an alias model, or dominance information for dereference assignments, or SSA form to help GVN. r? cjgillot cc `@jieyouxu` #132356 cc `@RalfJung` #133474		2025-04-03 19:17:33 +00:00
