  "message": "Work around scalar support bug in webgpu compilation. (#14629)\n\nSee https://github.com/openxla/iree/issues/11054#issuecomment-1670260451\r\n- this `multiple_results.mlir` test program uses scalars, and\r\nhttps://github.com/openxla/iree/pull/13711 changed the code path that\r\nscalar dispatches go down. This alternate code path does not appear to\r\nhave the same SPIR-V -\u003e WGSL compatibility patches as the tensor path,\r\nso we see compilation errors with messages like `entry point \u0027d0\u0027\r\nreferences multiple variables that use the same resource binding`. We\r\nshould fix that (and add tests so it doesn\u0027t regress again), but I want\r\nto keep webgpu runtime debugging work unblocked.\r\n\r\nThis modified program exhibits the same runtime-related issue as\r\nreported on https://github.com/openxla/iree/issues/13809 /\r\nhttps://github.com/openxla/iree/pull/14163:\r\n* The first invocation incorrectly returns \r\n  ```\r\n  2xf32\u003d2.23 2.45\r\n  2xf32\u003d0 0\r\n  ```\r\n* The second invocation correctly returns\r\n  ```\r\n  2xf32\u003d1.23 1.45\r\n  2xf32\u003d2.23 2.45\r\n  ```",
