-Subject: [PATCH] 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.
-
