+From ec3e1f411c332cbc2f2bc7ab7e2175ebf918b37a Mon Sep 17 00:00:00 2001
+From: Peter Oberparleiter <oberpar@linux.ibm.com>
+Date: Fri, 24 May 2019 16:56:52 +0200
+Subject: [PATCH 1/2] geninfo: Add intermediate text format support
+
+This change adds support for parsing the output of gcov's intermediate
+text file format as implemented by GCC versions 5 to 8.  The use of the
+gcov intermediate format should increase processing speed. It also
+provides branch coverage data when using the --initial command line
+option.
+
+Users can control whether geninfo uses the intermediate format via the
+geninfo_intermediate configuration file option. Valid values are:
+
+     0: Use normal text format
+     1: Use intermediate format
+  auto: Use intermediate format if available. This is the default.
+

+From e13b2b6f8443da660cafa0679c3b16240843ce9f Mon Sep 17 00:00:00 2001
+From: Peter Oberparleiter <oberpar@linux.ibm.com>
+Date: Fri, 24 May 2019 17:16:56 +0200
+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.
