Subject: [PATCH v8 05/13] perf stat: move target check to loop control statement
Date: Wed, 17 Jun 2020 11:38:21 +0300 [thread overview]
Message-ID: <62dc7c05-7195-9001-fbb0-425c6287ad21@linux.intel.com> (raw)
In-Reply-To: <0781a077-aa82-5b4a-273e-c17372a72b93@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.
