Subject: [Qemu-devel] [PATCH 01/12] tcg-s390: Fix movi
Date: Wed, 27 Mar 2013 11:52:22 -0700 [thread overview]
Message-ID: <1364410353-24728-2-git-send-email-rth@twiddle.net> (raw)
In-Reply-To: <1364410353-24728-1-git-send-email-rth@twiddle.net>
The code to load the high 64 bits assumed that the insn used to
load the low 64 bits zero-extended. Enforce that.
