  "message": "[LLVMGPUVectorDistribute] Add support for inter-subgroup multi_reduction (#19596)\n\nThis commit adds support for distribute multi_reductions where the\nreduction dimension(s) is/are distributed across subgroups.\n\nWe perform the existing reduction distribution, however, we are left\nwith partial reductions accross subgroups.\n\nThereafter, we insert tranfer_write / transfer_read to shared memory to\nachieve a layout change where\nwe re-distribute reduction subgroup tiles into element tile. Finally, we\ndo another multi_reduction to complete the reduction.\n\ncloses: https://github.com/iree-org/iree/issues/19578\n\n---------\n\nSigned-off-by: Manupa Karunaratne \u003cmanupa.karunaratne@amd.com\u003e",
