  "message": "[Codegen][CPU] Fold reshape-containing encoding relayouts to map_store. (#24533)\n\nGPU\u0027s configuration pipeline folds the `pack`/`expand_shape`/`transpose`\nrelayout chain from encoding materialization into a single\n`iree_linalg_ext.map_store` before tiling; CPU did not. For a non-row-\nmajor encoding swizzle the intervening `tensor.expand_shape` (not a\n`TilingInterface` op) blocks producer fusion and strands an untiled,\nwhole-tensor `pack` intermediate.\n\nMirror GPU on CPU:\n- Add `RelayoutCombinationScope::DispatchReshape`: like `Dispatch` but\nrestricted to chains whose backward slice contains an\nexpand/collapse_shape. Pure pack/unpack/transpose chains tile fine and\nare left alone.\n- Run `CombineResultLayoutTransformation` with that scope in the CPU\nconfiguration pipeline, after MaterializeDeviceEncoding.\n- Skip `map_load`/`map_store` as `getRootOperation` candidates, so a\ndispatch with a real compute op plus a `map_store` roots on the compute\nop.\n\nInert for existing (row-major) CPU encodings.\n\nProgress towards #24515.\n\nSigned-off-by: Benoit Jacob \u003cjacob.benoit.1@gmail.com\u003e\nCo-authored-by: Claude Opus 4.7 \u003cnoreply@anthropic.com\u003e",
