Subject: [PATCH] iwlegacy: make array interval static, makes object smaller
Date: Mon, 7 Oct 2019 14:41:13 +0100 [thread overview]
Message-ID: <20191007134113.5647-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate the array interval on the stack but instead make it
static. Makes the object code smaller by 121 bytes.
Before:
text data bss dec hex filename
167797 29676 448 197921 30521 wireless/intel/iwlegacy/common.o
After:
text data bss dec hex filename
167580 29772 448 197800 304a8 wireless/intel/iwlegacy/common.o
(gcc version 9.2.1, amd64)
