  "message": "[HashRecognize] Strip ValueEvolution (#148620)\n\nThe ValueEvolution logic is deeply flawed, and checking that zero-bits\nare shifted can be exploited for miscompiles. In an effort to redo\nHashRecognize with a pattern-matching based approach, extract and fix\nthe core logic of ValueEvolution, and strip it completely, showing that\nnone of the tests rely on the KnownBits computation of ValueEvolution.\n\nCo-authored-by: Piotr Fusik \u003cp.fusik@samsung.com\u003e",
