  "message": "[Codegen] Add pass to reinsert swizzle hints from alloc attributes (#24001)\n\nPart 2/3 of enabling XOR swizzle with software pipelining (#23919).\n\n**Overall plan:** `SwizzleHintOp` in the SSA chain blocks both\n`memref::multiBuffer` and `scf::pipelineForLoop`. The fix absorbs the\nhint into an alloc attribute before pipelining, preserves it through\nmulti-buffering, then re-inserts hints at leaf users afterward.\n\n**This PR:** Adds `ReinsertSwizzleHintsPass`, which traces `vector.load`\nand `vector.store` ops back to attributed `memref.alloc`s and inserts\n`collapse_shape -\u003e swizzle_hint -\u003e expand_shape` at each use site.\n`gather_to_lds` swizzle is handled separately in\n`AMDGPULowerCoalescedDMAToGatherLDS`, which applies an inverse swizzle\non the source indices directly -- `swizzle_hint` cannot be used there\nbecause the source is strided global memory. The pass is not yet wired\ninto any pipeline.\n\nAssisted-by: Cursor (Claude)\n\n---------\n\nSigned-off-by: Yu-Zhewen \u003czhewenyu@amd.com\u003e",
