Subject: [net-next 13/14] net/ixgbevf: make array api static const, makes object smaller
Date: Tue, 10 Sep 2019 09:34:33 -0700 [thread overview]
Message-ID: <20190910163434.2449-14-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <20190910163434.2449-1-jeffrey.t.kirsher@intel.com>
From: Colin Ian King <colin.king@canonical.com>
Don't populate the array API on the stack but instead make it
static const. Makes the object code smaller by 58 bytes.
Before:
text data bss dec hex filename
82969 9763 256 92988 16b3c ixgbevf/ixgbevf_main.o
After:
text data bss dec hex filename
82815 9859 256 92930 16b02 ixgbevf/ixgbevf_main.o
(gcc version 9.2.1, amd64)
