  "message": "[GPU] Allow swizzle promotion for transpose linalg.generic producers (preshuffling prs 1/3) (#24086)\n\nThis PR is the first in a series of PRs meant to enable preshuffling for\nscaled gemms.\n\nCurrently, operands to be swizzled are skipped when producing\nSwizzleHintOps if their producer is a linalg::LinalgOp. This means that\ntranspose linalg.generic ops feeding into a matmul with SwizzleOperand\npromotion would never get XOR swizzle hints applied to their output\nbuffer.\n\nThis change adds an exception: transpose linalg.generic producers\n(identified via linalg::isaTransposeOpInterface) no longer exit early.\nFor a GEMM dispatch where the transpose is folded into memory access,\nthis does not produce any extra allocations, bufferization correctly\nrecognizes that the `tensor.empty` associated to the TransposeOp and the\nSwizzleHintOp are redundant and removes the copy.\n\nNon-transpose linalg.generic producers continue to get the early return\nwith lowering_config annotation as before.\n\nMade-with: Cursor\n\n---------\n\nSigned-off-by: Muzammiluddin Syed \u003cmuzasyed@amd.com\u003e",
