  "message": "[GPU] Don\u0027t swap expand with slice in the same block (#23267)\n\nPrevents swapping tensor.extract_slice ops with tensor.expand_shape ops\nwhen they are in the same block during GPUFuseAndHoistParallelLoops.\nThis pattern is intended to be a tiling fusion pattern for\ntensor.expand_shape operations, which always begin with the ops in\ndifferent blocks. When the ops are in the same block, this does not open\nup more fusions, and instead moves the extract_slice further compute ops\nthat produce loads. This can block later optimizations that fold the\nslice into loading operations like vector.transfer_read.\n\nThis restriction is done through a control function to maintain the\nability to swap same-block slice + expand ops, in case it is needed for\nother use cases.\n\nci-extra: test_torch\n\n---------\n\nSigned-off-by: Max Dawkins \u003cmax.dawkins@gmail.com\u003e",
