  "message": "Introduce Flow InferNumericNarrow, OptimizeNumerics and CleanupNumericNarrowing passes (#7975)\n\nTogether, these passes:\r\n\r\n* Infer where it is safe to use a narrower, low precision type in place of floating point arithmetic.\r\n* Use this information to do targeted rewrites of linalg math ops.\r\n* Propagate casts.\r\n\r\nWhen combined with constant hoisting and eval, this will perform most of the work needed for low-precision optimization of inference workloads.\r\n\r\nAlso adds a new Util::NumericCastOpInterface and applies it to the casting ops in the arith dialect. I\u0027m going to put some more mileage on this and then will likely propose it for upstream.\r\n",
