  "message": "[CIR] Add noundef to memchr declaration and call sites (#191457)\n\nThe memchr LLVM declaration created by MemChrOp lowering had no\narg_attrs, so the lowered IR was missing `noundef` on all three\nparameters.  OGCG emits `noundef` on them.\n\nAdds `noundef` to both the `@memchr` declaration and each\n`call @memchr` instruction.\n\nMade with [Cursor](https://cursor.com)",
