From d2e8b911c0a0661d395ccac72156040702ac842d Mon Sep 17 00:00:00 2001 From: Mike Frysinger <vapier@gentoo.org> Date: Wed, 29 Jun 2011 11:58:04 +0000 Subject: [PATCH] panic: add noreturn attribute Since panic() never returns, we should add an appropriate attribute to let gcc improve optimization around it.
