  "message": "[SPIRV] Add native shapes for step op (#24046)\n\nSPIRV\u0027s TypeConverter failed with the following debug message:\n\n\u003e  illegal: not a valid composite type\n\nwhich for vectors and composite types means that the vector had an\ninvalid size.\n`SPIRVInitialVectorLoweringPass` includes the upstream VectorUnroll\npatterns which themselves can unroll vector.step.\nHowever, vector.step was skipped from unrolling since it lacked a target\nshaped defined in the VectorUnroll options.\n\n```\n[vector-unroll VectorUnroll.cpp:92 1] Get unroll shape for op vector.step\n[vector-unroll VectorUnroll.cpp:110 1] --vector op shape: 5\n[vector-unroll VectorUnroll.cpp:114 1] --no unrolling target shape defined \n%20 \u003d vector.step : vector\u003c5xindex\u003e-\u003e SKIP\n```\n\nTo fix this we simply define a target shape for vector.step following\nthe established conventions for other operations.\n\nFixes #24035\n\n---------\n\nSigned-off-by: Erick Ochoa \u003cerick.ochoalopez@amd.com\u003e\nCo-authored-by: Eric Feng \u003c55723758+efric@users.noreply.github.com\u003e",
