Subject: [Qemu-devel] [PATCH 7/8] target-ppc: Bug Fix: srawi
Date: Mon, 11 Aug 2014 14:23:28 -0500	[thread overview]
Message-ID: <1407785009-6538-8-git-send-email-tommusta@gmail.com> (raw)
In-Reply-To: <1407785009-6538-1-git-send-email-tommusta@gmail.com>

For 64 bit implementations, the special case of a shift by zero
should result in the sign extension of the least significant 32 bits
of the source GPR (not a direct copy of the 64 bit source GPR).
