Subject: [PATCH] mt76: make const array 'data' static, shrinks object size
Date: Sun, 30 Dec 2018 13:26:40 +0000 [thread overview]
Message-ID: <20181230132640.6916-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate the const array 'data' on the stack but instead
make it static. Makes the object code smaller by 78 bytes:
Before:
text data bss dec hex filename
5438 1080 0 6518 1976 mediatek/mt76/mt76x2/usb_mcu.o
After:
text data bss dec hex filename
5296 1144 0 6440 1928 mediatek/mt76/mt76x2/usb_mcu.o
(gcc version 8.2.0 x86_64)
