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.
