  "message": "Revert \"[LinalgExt] Generalize ArgCompareOp in GPUGeneralizeNamedOpsPass\" (#23074)\n\nReverts iree-org/iree#23015\n\n**Reason**\n\nDuring my process of plumbing arg_compare op along the VectorDistribute\npipeline, I found that working directly with ArgCompareOp (without\nconverting it to linalg.generic) will be a better solution.\n\nThe reason is that VectorDistribute performs two-level tiling:\n \n * Outer level: Partial reduction (PartialReductionOuterReduction)\n * Inner level: Inter-thread reduction (subgroup-wise)\n\nAdd PartialReductionOuterReduction support for ArgCompareOp directly, in\naddition to the existing PartialReductionOuterParallel (split-reduction)\nsupport. Extending the existing linalg.generic reduction support to\nhandle arg_reduce semantics would require drastic changes to the\ninfrastructure (upstream tilinginterface).\n\nWill add the core implementation back when after tiling we find it is\nuseful for the bufferization + vectorization + vector distribution\nphases.",
