Subject: [PATCH 20/20] lto: Don't inline __const_udelay
Date: Tue, 18 Feb 2014 15:28:58 +0100 [thread overview]
Message-ID: <1392733738-8290-21-git-send-email-andi@firstfloor.org> (raw)
In-Reply-To: <1392733738-8290-1-git-send-email-andi@firstfloor.org>
From: Andi Kleen <ak@linux.intel.com>
__const_udelay is marked inline, and LTO will happily inline it everywhere
Dropping the inline saves ~44k text in a non LTO build.
