11.2 Invoking gcov-tool
gcov-tool [global-options] SUB_COMMAND [sub_command-options] profile_dir
gcov-tool
accepts the following options:
-h
--help
- Display help about using
gcov-tool
(on the standard output), and exit without doing any further processing. -v
--version
- Display the
gcov-tool
version number (on the standard output), and exit without doing any further processing. merge
- Merge two profile directories.
-o directory
--output directory
- Set the output profile directory. Default output directory name is
merged_profile
. -v
--verbose
- Set the verbose mode.
-w w1,w2
--weight w1,w2
- Set the merge weights of the
directory1
anddirectory2
, respectively. The default weights are 1 for both.
rewrite
- Read the specified profile directory and rewrite to a new directory.
-n long_long_value
--normalize <long_long_value>
- Normalize the profile. The specified value is the max counter value in the new profile.
-o directory
--output directory
- Set the output profile directory. Default output name is
rewrite_profile
. -s float_or_simple-frac_value
--scale float_or_simple-frac_value
- Scale the profile counters. The specified value can be in floating point value, or simple fraction value form, such 1, 2, 2/3, and 5/3.
-v
--verbose
- Set the verbose mode.
overlap
- Compute the overlap score between the two specified profile directories. The overlap score is computed based on the arc profiles. It is defined as the sum of min (p1_counter[i] / p1_sum_all, p2_counter[i] / p2_sum_all), for all arc counter i, where p1_counter[i] and p2_counter[i] are two matched counters and p1_sum_all and p2_sum_all are the sum of counter values in profile 1 and profile 2, respectively.
-f
--function
- Print function level overlap score.
-F
--fullname
- Print full gcda filename.
-h
--hotonly
- Only print info for hot objects/functions.
-o
--object
- Print object level overlap score.
-t float
--hot_threshold <float>
- Set the threshold for hot counter value.
-v
--verbose
- Set the verbose mode.
