  "message": "[LLVMGPUVectorDistribute] Fix vector step distribute (#19227)\n\nCurrently, the \u0027thread_stride\u0027 of NestedLayoutAttr is misinterpreted as\nthe access stride of multi-dimensional vector.\n\nHowever, it turns out it correspond to tid -\u003e vtid mapping and the\nundistributed vector is packed as :\nsubgroup x batch x outer x thread x element\nwhere vtid is used to index \u0027thread\u0027 dimension.\n\nTherefore, this commit removes the usage of \u0027thread_stride\u0027s and\n\u0027subgroups_stride\u0027 when calculating the base constant offset and rather\nobtain them from packed undistributed vector shape.\n\nSigned-off-by: Manupa Karunaratne \u003cmanupa.karunaratne@amd.com\u003e",
