Yes, it improves alias-analysis. The interface to optimizers is the same as local points-to analysis. In addition to that it computes IPA mod-ref information and stores it at call sites. That information is used by the alias-oracle as well. There are testcases in gcc.dg/ipa/ipa-pta-*.c (they are mostly correctness testcases but also a few optimization ones).
