Subject: [Qemu-devel] [PULL 05/18] target-alpha: Set EXC_M_SWC for exceptions from /S insns
Date: Wed, 9 Jul 2014 09:20:21 -0700 [thread overview]
Message-ID: <1404922834-28169-6-git-send-email-rth@twiddle.net> (raw)
In-Reply-To: <1404922834-28169-1-git-send-email-rth@twiddle.net>
Previously forgotten, the kernel needs the software completion bit to
know that it needs to emulate software completion qualified insns.
