  "message": "Reapply \"[SCEVExp] Use SCEVPtrToAddr in tryToReuseLCSSAPhi if possible. (#180257)\"\n\nThis reverts commit cb905605b2e95f88296afe136b21a7d2476cb058.\n\nRecommit the patch with a small change to check the destination\ntype matches the address type, to avoid a crash on mismatch.\n\nOriginal message:\n\nThis patch updates tryToReuseLCSSAPhi to use SCEVPtrToAddr, unless using\nSCEVPtrToInt allows re-use, because the IR already contains a re-usable\nphi using PtrToInt.\n\nThis is a first step towards migrating to SCEVPtrToAddr and avoids\nregressions in follow-up changes.\n\nPR: https://github.com/llvm/llvm-project/pull/178727\n",
