From e3809a37d45651f2a08be03dda0b48275a6e04d8 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Tue, 15 Mar 2011 20:10:12 +0000 Subject: sim: bfin: skip acc/ASTAT updates for moves No point in moving unchanged acc values to the acc regs, and avoid updating the acc ASTAT bits when only reading. This fixes incorrect changing of the ASTAT bits when they're only being read.
