Subject: [PATCH 4.4 04/37] sh: New gcc support
Date: Tue, 5 Jun 2018 19:01:09 +0200 [thread overview]
Message-ID: <20180605170109.155041777@linuxfoundation.org> (raw)
In-Reply-To: <20180605170108.884872354@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yoshinori Sato <ysato@users.sourceforge.jp>
commit 940d4113f3306e07a1f86541489b686d1a979d54 upstream.
New gcc (4.8 or later) used new shift helper functions.
So we need added new helper to private libgcc.
