+Subject: [PATCH 2/2] geninfo: Add intermediate JSON format support
+
+This change adds support for parsing the output of gcov's intermediate
+JSON file format as implemented by GCC version 9.
+
+Note: The way that the intermediate file format support is implemented
+in geninfo removes the need to parse .gcno files directly. Since geninfo
+does not include support for parsing GCC 9 .gcno files, using the
+intermediate format is the only option for geninfo to collect coverage
+data generated by GCC version 9.
