Subject: [PATCH 2/2] parser: define __builtin_unreachable
Date: Sat, 10 Jul 2010 10:39:22 +0200	[thread overview]
Message-ID: <1278751162-10053-2-git-send-email-jslaby@suse.cz> (raw)
In-Reply-To: <AANLkTikFmeXz9og4t98jm6QcAdRa6rIeCAv3oeFnTgd8@mail.gmail.com>

Gcc 4.5 defines
extern void __builtin_unreachable(void);
so, add it also to sparse.
