  "message": "[AMDGPU] Improve llvm.amdgcn.wave.shuffle handling for pre-GFX8 (#174845)\n\nBefore, GlobalISel would still return true for lowering the intrinsic\nfor GFX7 and earlier even though the required ds_bpermute_b32\ninstruction is not supported. After this change, GlobalISel will\nproperly report failure to select in this case. Testing is updated\nappropriately.\n\nSigned-off-by: Domenic Nutile \u003cdomenic.nutile@gmail.com\u003e",
