Option |
Default |
|
-follow-child-processes |
no |
|
Controls whether PureCoverage monitors child processes created when an instrumented program forks. If this option is not specified, PureCoverage does not accumulate counts for child processes, and does not write counts data for the child process to the .pcv file. If this option is set to yes, PureCoverage accumulates coverage data for the child process. When the child process exits or executes another process, PureCoverage writes the accumulated counts in the child to the .pcv file. Likewise, when the parent process exits, PureCoverage writes counts accumulated in the parent to the .pcv file. By default, PureCoverage writes both parent and child counts to the same .pcv file ( %v.pcv ), so that viewing that file shows the combined coverage data. To
separate the counts for parent and child, you can use the option -counts-file
= %v.%p.pcv
to specify a counts file including the process pid
in the
filename, or call the API function purecov_set_filename()
in either
or both the parent or child process to control where the data is written.

-purecov-granularity |
line (if debug data is available) |
|
Controls the level of detail at which PureCoverage collects data. Allowable values are line, basic-block, and function. By default, PureCoverage collects data at line level if debug data is available; otherwise, it collects data at the function level.
