  "message": "[profcheck] Fix missing profile metadata in ExpandMemCmp (#169979)\n\nThis patch fixes a profile metadata missing in the `ExpandMemCmp` pass\nwhen it expanding `memcmp` calls. This would cause branches between\ndifferent blocks to lose their profile data, potentially leading to\nsuboptimal code generation.\n\nThe patch updates the `ExpandMemCmp` pass to set branch weights to a\ndefault `unknown`(50/50 weights) value when a profile is available. This\nprevents the expansion from making a previously profiled branch\nunprofiled.\n\nThe patch also includes updates to the tests to reflect the new branch\nweights.\n\nCo-authored-by: Jin Huang \u003cjingold@google.com\u003e",
