Subject: [PATCH] net: hns3: make array spec_opcode static const, makes object smaller
Date: Thu, 19 Aug 2021 12:58:13 +0100 [thread overview]
Message-ID: <20210819115813.6692-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate the array spec_opcode on the stack but instead it
static const. Makes the object code smaller by 158 bytes:
Before:
text data bss dec hex filename
12271 3976 128 16375 3ff7 .../hisilicon/hns3/hns3pf/hclge_cmd.o
After:
text data bss dec hex filename
12017 4072 128 16217 3f59 .../hisilicon/hns3/hns3pf/hclge_cmd.o
(gcc version 10.3.0)
