Subject: [PULL 05/21] cutils: remove one unnecessary pointer operation
Date: Mon, 15 Jul 2019 15:51:09 +0200 [thread overview]
Message-ID: <20190715135125.17770-6-quintela@redhat.com> (raw)
In-Reply-To: <20190715135125.17770-1-quintela@redhat.com>
From: Wei Yang <richardw.yang@linux.intel.com>
Since we will not operate on the next address pointed by out, it is not
necessary to do addition on it.
After removing the operation, the function size reduced 16/18 bytes.
