  "message": "[ir] Decompose vec2\u003cf16\u003e and vec4\u003cf16\u003e to u16 base type\n\nSmallestElementSize now returns 2 for vec2\u003cf16\u003e and vec4\u003cf16\u003e, making\nSetBaseEleType use u16 instead of u32/vec2u to improve performance for\nORT models.\n\nThis commit also updates some test expectations for\nStorage_AccessU32_StoreVec2h/Storage_AccessU32_StoreVec4h and renames\nduplicate tests for clarity.\n\nBug: 459523229\nChange-Id: I506b9e6508b0586b5dec312d77cd152a88d278c7\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/304595\nReviewed-by: James Price \u003cjrprice@google.com\u003e\nReviewed-by: Shao, Jiawei \u003cjiawei.shao@intel.com\u003e\nCommit-Queue: Mei, Shanxing \u003cshanxing.mei@intel.com\u003e\n",
