Subject: [PATCH v5 05/13] perf stat: move target check to loop control statement
Date: Mon, 1 Jun 2020 18:55:04 +0300 [thread overview]
Message-ID: <08f23d8b-5406-d9be-2cda-cda187cbbdfd@linux.intel.com> (raw)
In-Reply-To: <e5cac8dd-7aa4-ec7c-671c-07756907acba@linux.intel.com>
Check for target existence in loop control statement jointly with 'stop'
indicator based on command line values and external asynchronous 'done'
signal.
