From b5edcddda31b464e73cc0a79e88457e603c3b247 Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Tue, 16 Jun 2015 22:57:47 +0200 Subject: target-s390x: fix MOVE LONG instruction The MOVE LONG instruction should pad the destination operand with the byte from bit positions 32-39 of the source length (r2 + 1), not with the same byte in the source address.
