  "message": "[LVI] Skip self loops in `solveBlockValueNonLocal` (#127763)\n\nWe cannot infer more information from backedges in\n`solveBlockValueNonLocal`. However, since DT is unavailable in LVI,\nthere is not a precise way to check whether a BB edge is a backedge.\nThis patch only skips self loops to unblock the range analysis.\n\nThe motivating case is extracted from\nhttps://github.com/llvm/llvm-project/pull/127663.\n\nCompile-time impact is high:\nhttps://llvm-compile-time-tracker.com/compare.php?from\u003d84ddda58c870681dd12ed765e9d59d5e00567f94\u0026to\u003daf032f1351358f2f5b5d9f4e87c5601c23b9bd37\u0026stat\u003dinstructions:u",
