From 355d4d1c00e708907ff391c24ca708f1c9c06bf0 Mon Sep 17 00:00:00 2001 From: Pavel Dovgalyuk Date: Wed, 18 Apr 2018 09:41:53 +0300 Subject: m68k: fix subx mem, mem instruction This patch fixes decrement of the pointers for subx mem, mem instructions. Without the patch pointers are decremented by OS_* constant value instead of retrieving the corresponding data size and using it as a decrement.
