Subject: [PATCH 2/5] openrisc: link to libgcc
Date: Mon, 25 Jun 2012 14:44:38 +0200 [thread overview]
Message-ID: <1340628281-8774-3-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1340628281-8774-1-git-send-email-s.hauer@pengutronix.de>
To get symbols like __ashrdi3.
Franck started generating these symbols from gcc assembly, which seems
to be the cleaner approach. The simpler approach for now to get additional
symbols is to link in libgcc, which is the same as the kernel does.
