Subject: [PATCH] wireless: iwlegacy: make const array static to shink object code size Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 8bit
Date: Thu, 21 Sep 2017 23:56:30 +0100 [thread overview]
Message-ID: <20170921225630.21916-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate const array ac_to_fifo on the stack in an inlined
function, instead make it static. Makes the object code smaller
by over 800 bytes:
text data bss dec hex filename
159029 33154 1216 193399 2f377 4965-mac.o
text data bss dec hex filename
158122 33250 1216 192588 2f04c 4965-mac.o
(gcc version 7.2.0 x86_64)
