Subject: [PATCH] brcmsmac: make array addr static const, makes object smaller
Date: Thu, 19 Aug 2021 13:55:52 +0100 [thread overview]
Message-ID: <20210819125552.8888-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate the array addr on the stack but instead it
static const. Makes the object code smaller by 79 bytes:
Before:
text data bss dec hex filename
176015 54652 128 230795 3858b .../broadcom/brcm80211/brcmsmac/main.o
After:
text data bss dec hex filename
175872 54716 128 230716 3853c .../broadcom/brcm80211/brcmsmac/main.o
(gcc version 10.3.0)
