Date: Tue, 25 Mar 2014 22:44:34 +1100 Message-Id: <1395747879-5948-29-git-send-email-anton@samba.org> In-Reply-To: <1395747879-5948-1-git-send-email-anton@samba.org> References: <1395747879-5948-1-git-send-email-anton@samba.org> Cc: linuxppc-dev@lists.ozlabs.org List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , From: Rusty Russell ELFv2 doesn't use function descriptors, so we don't expect symbols to start with ".". But because depmod and modpost strip ".", and we have the special symbol ".TOC.", we still need to do it.
