Subject: [PULL 02/10] target/s390x: Fix SLDA sign bit index
Date: Wed, 19 Jan 2022 09:32:07 +0100 [thread overview]
Message-ID: <20220119083215.120911-3-thuth@redhat.com> (raw)
In-Reply-To: <20220119083215.120911-1-thuth@redhat.com>
From: Ilya Leoshkevich <iii@linux.ibm.com>
SLDA operates on 64-bit values, so its sign bit index should be 63,
not 31.
Fixes: a79ba3398a0a ("target-s390: Convert SHIFT DOUBLE")
Reported-by: David Hildenbrand <david@redhat.com>
Signed-off-by: Ilya Leoshkevich <iii@linux.ibm.com>
