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 and directory2, respectively. The default weights are 1 for both.
merge-stream
Collect profiles with associated filenames from a gcfn and gcda data stream. Read the stream from the file specified by file or from stdin. Merge the profiles with associated profiles in the host filesystem. Apply the optional weights while merging profiles.
For the generation of a gcfn and gcda data stream on the target system, please have a look at the __gcov_filename_to_gcfn()
and __gcov_info_to_gcda()
functions declared in #include <gcov.h>
.
-v
--verbose
Set the verbose mode.
-w w1,w2
--weight w1,w2
Set the merge weights of the profiles from the gcfn and gcda data stream and the associated profiles in the host filesystem, 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.
