+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.
