  "message": "[Codegen][GPU] Guard multi-buffering behind pipelining pre-flight check (#24114)\n\nMove computeStageClassification before multiBufferLDSAllocations as a\npre-flight validation. If stage classification fails (e.g. gather_to_lds\ninside scf.if, insufficient loop iterations), bail out before mutating\nthe IR. This prevents doubled LDS allocations with no actual pipelining.\n\nAfter multi-buffering succeeds, re-run classification on the mutated IR\nto capture the correct double buffered schedule.\n\nSigned-off-by: jerryyin \u003czhuoryin@amd.com\u003e",
